Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a program recording system for recording a broadcast program, and a remote control device, method and program.

[0002]

2. Description of the Related Art Television broadcasting through satellite waves or terrestrial waves is being digitized. The digitization of broadcasting will increase the number of channels. As the number of channels increases, the user's options for selecting programs also increase, but it becomes difficult for the user to select programs only by switching channels. Therefore, for example, in BS digital broadcasting, information for electronic program guide (hereinafter referred to as “EPG information”) is multiplexed with a video signal and an audio signal and transmitted in a television signal. The EPG information indicates the broadcast schedule of the program, and the broadcast receiving device determines the EP
The program guide is displayed on the monitor in correspondence with the G information. The user may select a program to watch from among the programs included in the program guide displayed on the monitor. If the selected program is not currently being broadcast, it means that viewing or recording of the program has been reserved.

The EPG information is repeatedly broadcast, and when the broadcast schedule of the program is changed, the change is reflected in the EPG information on the broadcasting station side. For example, even if a program is added, if the program is found in the program guide corresponding to the changed EPG information, the user can select the added program for viewing or recording reservation, or can newly view the program. You can make a recording reservation in.

If the user is out, the user can check the program table by using the mobile phone. The EPG information is provided not only by broadcasting but also through the Internet. As described in Japanese Patent Laid-Open No. 2001-145140, the user confirms the program guide with a mobile phone having a browser function. Moreover, it is also possible to make a recording reservation of a program.

[0005]

However, the display area secured in a remote control device such as a mobile phone or a remote controller is limited. For this reason, the listing of programs is often insufficient, and the user may overlook even if the program added to the latest program guide is included.

The present invention has been made in view of the above problems in the prior art, and a program recording system which allows a user to easily and surely notice a change in a broadcast schedule by using a remote control device, Another object of the present invention is to provide a remote control device, method and program.

[0007]

According to the present invention, a recording device for recording a broadcast program, a server device for storing information indicating a broadcast schedule of the broadcast program, and a remote control device for remotely controlling the recording device. There is provided a program recording system including:

[0008] In the recording device, the holding means holds the recording reservation information including at least the recording start time and the recording time or the recording end time of the program reserved for recording. The control means controls the recording means based on the held recording reservation information, and the program reserved for recording is recorded. The update method is
When there is an update request from the outside, the recording reservation information is updated accordingly.

The user can update the recording reservation information by using the remote control device. In this case, the acquisition means acquires the broadcast schedule information from the server device and the recording reservation information from the recording device. The determining means determines the display information displayed on the display means based on the content of the acquired recording reservation information different from the broadcast schedule information.
Then, the remote control means requests the recording device to update the recording reservation information.

In such a program recording system, the user can easily and surely notice the change in the broadcast schedule by checking the display information.

The display information includes, for example, information for displaying, in a identifiable manner, a program whose broadcast schedule has been changed among programs reserved for recording. The user does not need to check the information for all the programs reserved for recording, but only the recording reservation information for the programs whose broadcast schedule has been changed.

When the user changes the recording reservation information in accordance with the change of the broadcast schedule, the update request is a request for matching the recording reservation of the program whose broadcast schedule has been changed with the changed broadcast schedule.

The server device may be provided in the recording device instead of separately from the recording device. In this case, the acquisition means substantially acquires the recording reservation information and the broadcast schedule information from the recording device.

When a new program is added to the broadcast schedule, the added program may be included in the display information to notify the user. However, as described in Japanese Patent Laid-Open No. 2000-358199, recording is performed. The device may actively notify the user of the added program. When determining that the new program newly added to the schedule information of the program is the program desired by the user, the broadcast receiving device described in this publication notifies the user that the program desired by the user has been added. The determination is made based on the program narrowing information preset by the user. The program narrowing-down information is information on keywords or genres input or selected by the user to narrow down the programs that the user desires. However, the user has to set keywords and genres in advance, and it is necessary to set the program narrowing-down information every time the program desired by the user changes due to changes in program organization or tastes. If the user feels annoyed to change the settings,
The user's recent interest will not be reflected in the notified new program.

In order to avoid such troublesomeness, the recording apparatus may include additional program selecting means and program notifying means. The additional program selecting means selects a program from the programs added to the broadcast schedule based on at least one of the recorded program information regarding the recorded program and the recording reservation information. The program notifying means notifies the remote control device of the selected program. The interest of the user is reflected in the programs already recorded or the programs reserved for recording. The recorded program information or the recording reservation information is not the information registered by the user to narrow down the notification programs, but the recording device can automatically hold such information. Therefore, the recorded program information or the recording reservation information is notified based on the recorded program information or the recording reservation information. By selecting the program, it is possible to significantly reduce the user's annoyance.

Further, in the recording device, the control means may automatically record or record the program added to the broadcast schedule. If the program added to the broadcast schedule is automatically reserved for recording or recorded, even if the period from the addition of the program to the broadcast is short and the user does not immediately know the addition of the program, You can avoid missing the program.

However, in this case, the recording device may reserve or record the program for which the user does not feel the recording reservation or the necessity of recording. Therefore, the recording device reserves the recording of the program added to the broadcast schedule. Alternatively, it is preferable to send a message notifying that the recording has been performed to the remote control device.

Further, the remote control device may include comparison means and deletion instruction means. The comparison means compares the recording capacity required for recording the program to which the recording reservation is added with the remaining capacity of the recording medium on which the program is recorded, and displays the comparison result on the display means. If the user determines from the displayed comparison result that the remaining capacity of the recording medium is insufficient for recording the program, the user deletes the program already recorded on the recording medium by using the deletion instruction means. With this, even when the user adds a program to be reserved for recording by using the remote control device, the recording capacity for recording the program is appropriately secured,
It is possible to avoid that only a part of the program is recorded or the recorded program is inadvertently overwritten.

Further, in order to secure a recording capacity for recording a program, the remote control device may include a bit rate instruction means. When it is determined from the displayed comparison result that the remaining capacity of the recording medium is insufficient for recording the program, the user uses the bit rate instructing means to instruct the recording bit rate of the program. Thus, even when the user adds a program to be reserved for recording by using the remote control device, the recording capacity for recording the program is appropriately secured.

Further, the update request made by the remote control means of the remote control device to the recording device may include personal information for specifying the user of the remote control device. As personal information,
For example, a telephone number of a mobile phone or an ID stored in an IC card detachably attached to the mobile phone is used. If the personal information included in the update request is used, the recording device can identify the user of the remote control device, and can control recording or reproduction based on the identification result.

For example, a recording device capable of reproducing and displaying a program is often shared by families, but the storage capacity of the recording medium is also increased, and the number of recorded programs is significantly increased. It is difficult for the user to find the recording reservation or the recorded program. Similarly, a plurality of people may add markers to different scenes in one program, but it is difficult to find a marker added by the user himself. Even in such a case, if the recording device filters and displays recorded programs and marked images based on personal information, the user reproduces and displays from among the programs for which the user himself has performed the recording operation. You can easily select programs and scenes.

According to another aspect of the present invention, the above remote control device and remote control method are also provided. In the remote control method of remotely controlling the recording device by using the remote control device, the broadcast schedule information is acquired from the server device and the recording reservation information is acquired from the recording device. Then, the display information displayed on the display means is determined based on the content of the acquired recording reservation information different from the broadcast schedule information,
A request for updating the recording reservation information is issued to the recording device.

Further, a program for causing a computer to execute this remote control method is also provided. In this case, for example, a computer operating as a remote control device acquires schedule information and recording reservation information, determines display information, and makes an update request. This program can be distributed through telecommunication lines such as the Internet,
It is distributed in the state of being stored in a computer-readable recording medium such as a CD-ROM.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. (Embodiment 1) As shown in FIG.
The program recording system in 1 includes a recording device 1 and a remote control device 100.

The recording device 1 receives the output signals of a plurality of transponders (repeaters) at the antenna 2. Tuner 3
Selects one of the signals received by the antenna 2 and outputs the selected signal to the transport decoder 4. The transport decoder 4 selects one of the plurality of channels included in this signal. Usually, this output signal (transport stream) contains programs of 4 to 6 channels. Further, the transport decoder 4 uses a signal of a selected channel (which may be referred to as “channel 1” in the following description) to generate a video signal, an audio signal, and an SI (Service Information).
Etc. are separated and the video signal and the audio signal are output to the recording means 5. SI is the EIT for the program for each channel
(Event Information Table)
including.

The EIT is a table in which program information is described for each of a plurality of events (programs), and is used here as information indicating the broadcast schedule of the program. The event information in which the program identification number is described in the program information
D field, start in which the start time of the program is described
A field, a duration field in which the length of time the program is broadcast is described, and a program name field in which the title of the program is described are included.

For example, when baseball is broadcast from 7:00 to 9:00, as shown in FIG. 2A, "01" is described in the eventid field for the program,
“7:00” is described in the start field, and du
"2:00" is described in the relation field, and "baseball" is described in the program name field. Also, 9: 0
If the drama will be broadcast from 0 to 11:00
As shown in (B), the eventid for the program
“02” is described in the field, “9:00” is described in the start field, “2:00” is described in the duration field, and “drama” is described in the program name field.

The recording control means M takes out such an EIT from the transport decoder 4, and the recording means 5
Under the control of the recording control means M, the EIT information is displayed on the monitor 6 as a program guide.

When the recording of the program selected from this program table is reserved, the recording control means M extracts the identification number, title, start time and broadcast time of the selected program from the EIT. The recording control means M defines the extracted start time and broadcast time as the recording start time and recording time, and stores the program identification number, title, broadcast channel, recording start time, and recording time in the storage means 7 as program recording information. To do. If recording is reserved for the program with the identification number "01" shown in FIG. 2, the holding unit 7 stores the identification number "01", the title "baseball", the broadcast channel "1", and the recording start time. "7:00",
The recording reservation information including the information "2:00" is held as the recording time.

At the recording start time, the recording control means M
Controls the recording means 5 based on the recording reservation information held in the holding means 7, and the recording means 5 decodes the video and audio signals of channel 1 output from the transport recorder 4, and decodes the decoded video and The audio signal is recorded on the recording medium 8. Under the control of the recording control means M, the recording means 5 records the video and audio signals on the recording medium 8 from the start of recording until the recording time elapses, and when the recording time elapses, the recording is terminated. By this, the holding means 7
The program holding the recording reservation information is recorded.

The updating means 9 updates the recording reservation information held in the holding means 7 in response to an update request from the outside.

The user can use the remote control device 100 in order to update the recording reservation information and remotely control the other recording devices 1. Remote control device 100
Corresponds to a remote control attached to the recording device 1 or a mobile phone owned by the user.

When the user uses the remote control device 100 to instruct to update the recording reservation information, the acquisition means 101, the determination means 102, and the remote control means N of the remote control device 100.
Operates according to the procedure shown in FIG.

First, the acquisition means 101 acquires information indicating a broadcast schedule and recording reservation information from the recording device 1 (S1). In this embodiment, the server device 10 is
It is provided in the recording device 1, and the server device 10 receives the request from the acquisition means 101 and transmits the broadcast schedule information and the recording reservation information to the acquisition means 101. For example, the server device 10 operates as an HTTP server, and the acquisition unit 101 operates as an HTTP client.
The server device 10 always takes out EIT information from the transport decoder 4 and stores it as broadcast schedule information. In addition, in this embodiment, the acquisition unit 1
When the request is received from 01, the program on the server device 10 operates, and the recording reservation information held in the holding means 7 is read by the server device 10 according to the program. The recording reservation information read by the server device 10 is transmitted from the server device 10 to the acquisition means 101 together with the broadcast schedule information. The acquisition means 101 is broadcast schedule information separately from the server device 10 and the holding means 7. Alternatively, the recording reservation information may be acquired. For example, as shown in FIG. 4, the program recording system may include a server device 10 as an HTTP server device on the Internet separately from the recording device 1. In that case, the acquisition means 101 causes the server device 10 to operate. Broadcast schedule information and recording reservation information from the recording device 1.

When the acquisition unit 101 acquires the broadcast schedule information and the recording reservation information, the determination unit 102 displays the display information displayed on the display unit 103 based on the contents of the acquired recording reservation information different from the broadcast schedule information. Is determined (S2).

For example, the determining unit 102 compares the title, the recording start time, and the recording time with the title, the start time, and the broadcast time included in the EIT for each program for which the recording reservation information is acquired, and there is a difference. Determine whether or not. If there is a different program, the determining unit 102 extracts the program as a program whose broadcast schedule has been changed, and generates display information based on the extracted program. This display information includes information for displaying the extracted program in a distinguishable state among the programs reserved for recording. This information is
It may be information indicating the display color of the character indicating the extracted program, or the background color of the area indicating the extracted program or the thickness of a rectangular frame surrounding the area. These pieces of information on the extracted program will be different from the information on the other programs for which recording is reserved. When the server device 10 is in the recording device 1, since the recording device 1 holds both the recording reservation information and the broadcast schedule, the recording device 1 does not communicate with an external device. It is also possible to generate difference information based on the difference between the two. In this case, as shown in FIG. 5, the recording device 1 is provided with the difference information generating means 7A for generating the difference information based on the difference between the recording reservation information and the broadcast schedule.
The acquisition means 101 of the remote control device 100 acquires the difference information from the recording device 1, and the determination means 102 acquires the acquisition means 10.
The display information is generated on the basis of the difference information acquired by No. 1 or transmitted from the recording device 1.

When the determining means 102 generates the display information,
The display information is output to the display means 103, and the display means 10
Display information is displayed in 3 (S3).

Recording is reserved only for the two programs shown in FIG. 2, and thereafter, the EI received by the recording device 1 is reserved.
In the information of T, it is assumed that the program broadcasted on channel 1 for two hours from 9:00 is changed from drama to news.
In this case, the recording reservation screen as shown in FIG. 6 is displayed on the display means 103. In this recording reservation screen, the thickness of the rectangular frame surrounding the area for the program whose broadcast schedule has been changed is larger than the thickness of the rectangular frame surrounding the area for the program whose broadcast schedule has not changed,
Both can be distinguished by the difference in the thickness of the rectangular frame. For simplification, the example in which recording is reserved for only two programs is shown, but even if recording is reserved for three or more programs, the user can easily select a program whose broadcast schedule is changed in the same manner. Moreover, it is possible to surely notice, and it is possible to immediately determine whether or not the recording reservation information needs to be updated.

The remote control device 100 indicates that the user who has judged that it is not necessary to record the news updates the recording reservation information using the input means 104 and deletes the recording reservation.
(S4), the remote control means N requests the recording device 1 to update the recording reservation information according to the instruction (S5). This request is transmitted to the updating means 9, and the updating means 9 deletes the corresponding recording reservation information held in the holding means 7 according to the received request.

Also, when the user determines that the news needs to be recorded and instructs the remote control device 100 to change the recording reservation, the remote control means N also
According to the instruction, the recording device 1 is requested to update the recording reservation information. In this case, the update request is a request for matching the recording reservation of the program whose broadcast schedule has been changed with the changed broadcast schedule. The remote control means N
The new recording reservation information generated from the broadcast schedule information may be transmitted to the updating means 9, and the updating recording means 9 may overwrite the corresponding recording reservation information held in the holding means 7 with the received recording reservation information, or remote control. The means N may simply request a match, and the updating means 9 may update the corresponding recording reservation information held in the holding means 7 according to the changed broadcast schedule.

When the remote control device 100 is a mobile phone having a browsing function and is equipped with a CPU and a memory for storing a program for realizing the browsing function and other functions, the remote control device 10
Even if 0 is not provided with dedicated hardware, the CPU can execute the above-described procedure and operate as each unit if the above-described procedure is described in the program. (Embodiment 2) In this embodiment, a recording device 1 and a remote control device 100 as shown in FIG. 7 are used as a recording device and a remote control device of a program recording system.

In this recording apparatus 1, the recording means 5 is A
The V decoder 5A is used, and the HDD 8A is used as the recording medium 8 for recording the program. In addition, RAM11
Is used as the holding unit 7, and the recording reservation information is held in the management table in the RAM 11. The recording device 1 uses the infrared interface 1 for communication with the remote control device 100.
2 or the communication network face 13 can be used. The communication network interface 13 is an interface for using a communication network such as a public telephone line network, a mobile communication network, or the Internet. Further, the recording device 1 includes a CPU 14 and a ROM 15, and the CPU 14 executes various programs stored in the ROM 15 to realize various functions. The updating unit 9 and the recording control unit M are also the CPU 14
Is realized by executing the program.

On the other hand, in the remote control device 100, the monitor 103A is used as the display means 103, and the input means 10 is used.
The input interface 104A is used as 4. Further, this remote control device 100, like the recording device 1,
Infrared interface 105, communication network interface 1
06, RAM 107, CPU 108, and ROM 109
The CPU 108 executes various programs stored in the ROM 109 to realize various functions.
Acquisition means 101, determination means 102, and remote control means N
Is also realized by the CPU 108 executing the program. The infrared interface 1 is used for communication performed by the acquisition unit 101 and the remote control unit N with the recording device 1.
05 or the communication network interface 106 will be used. In this embodiment, the remote control means N
Not only makes an update request, but also controls the entire remote control device 100.

The input interface 104A of the remote control device 100 is provided with a plurality of selection keys K as shown in FIG. 6, and the user can operate the selection keys K to give various instructions.

When the user uses the input interface 104A to instruct the recording reservation, this instruction is notified to the remote control means N of the remote control device 100. Upon receiving the notification, the remote control means N displays an initial screen as shown in FIG. 8 on the monitor 103A of the remote control device 100 (FIG. 9, step S101). The user sets the EPG display time, the EPG display channel, and the place of use while looking at this display.

The EPG display time means a time range of EPG information displayed on the monitor 103A. User is 7: 0
To display the EPG information from 0 to 11:00, the input interface 104A is used to display "7:00" in the display start time setting area E1 and "11:00" in the display end time setting area E2. Set.

The EPG display channel is the monitor 103A.
It means the channel of EPG information displayed in. When the user wants to display the EPG information of channel 1, "channel 1" is set in the display channel setting area E3.

The use place means a place where the remote control device 100 is used at the time of recording reservation. When the remote control device 100 is used in the room where the recording device 1 is installed, "indoor" is set in the use place setting area E4.
When "indoor" is set as the place of use, communication between the recording device 1 and the remote control device 100 is performed via the infrared interfaces 12 and 105. On the other hand, when the remote control device 100 is used outside the room where the recording device 1 is installed, "outdoor" is set in the use place setting area E4. When “outdoor” is set as the place of use, communication between the recording device 1 and the remote control device 100 is performed via the communication network interfaces 13 and 106.

When the EPG display time and the EPG display channel do not have to be limited in particular, the user can set a value of "ALL" indicating that they are not required to be limited in these items. However, with such a setting, the number of display objects increases, so that the communication time and the communication cost required for communication between the recording device 1 and the remote control device 100 increase.

After setting the EPG display time, the EPG display channel, and the place of use, the user places the cursor on the enter button on the monitor 103A. When the user presses the selection key K included in the input interface 104A of the remote control device 100 in this state (FIG. 9, step S10).
2) The information set as above is notified to the remote control means N.

Here, the remote control means N indicates that the EPG display time is from 7:00 to 11:00.
A recording reservation start command including a parameter indicating that the G display channel is channel 1 is transmitted to the recording device 1 (FIG. 9, step S103).

When the recording apparatus 1 receives the recording reservation start command (FIG. 10, step S11), the recording control means M
Interprets the content of the parameter included in this command, recognizes that the EPG display channel is channel 1, and controls the tuner 3 to select channel 1. Further, the recording control means M stores the parameter included in the recording reservation start command in the RAM 11 and starts the process of taking out the EIT from the transport decoder 4 based on the content of this parameter (FIG. 10, step S1).
2).

As the parameter, the EPG display time is 7: 0.
Since it is shown that it is from 0 to 11:00,
In this case, the recording control means M will take out the information of all the programs whose values described in the start field are from 7:00 to 11:00. However,
Here, it is assumed that the information of the two programs shown in FIGS. 2A and 2B is taken out.

The recording control means M operates from 7:00 to 9:00.
Until 9:00 to 11:00 with baseball being broadcast
Recognize that the drama will be broadcast until 0. That is, the recording control means M stores the management table T on the RAM 11.
After generating, the information of the baseball broadcast and the information of the drama broadcast are stored in each field of the management table T (see FIG. 1).
0, step S13). As shown in FIG. 11, the management table T stores the recording reservation state indicating whether the recording reservation is ON or OFF and the information corresponding to the EIT in association with each other. In the case of the example of FIG. 11, FIG.
The recording reservation state is described in the recording presence / absence field for each of the information of the two programs shown in (A) and (B).

However, the baseball broadcast and the drama broadcast are not reserved for recording, and are only candidates for recording reservation at this point. Therefore, “OFF” is set in the recording / non-recording field of the management table T for these broadcasts.

Next, the recording control means M stores information indicating that the notification destination is indoors in the RAM 11 and then
An EPG information notification including various kinds of information stored in the RAM 11 as parameters is transmitted to the remote control device 100 (FIG. 10, step S14). When the EPG information notification is received by the remote control means N of the remote control device 100,
A recording reservation screen is displayed on the monitor 103A in which the necessity of recording reservation of the broadcast program can be selected (FIG. 9, step S10).
4 → S105).

On this recording reservation screen, as shown in FIG. 12, not only the area E12 for setting the necessity of recording reservation of the broadcast program but also the setting contents on the recording device 1 side (that is, the EPG information notification is displayed). An area E11 for displaying (contents of included parameters) is also provided.

The user can easily know the current setting contents on the recording device 1 side by referring to the display in the area E11.

However, the areas E11 and E12 do not necessarily have to be provided separately. For example, when the necessity of recording reservation of a broadcast program is set using a pull-down menu, the pull-down menu displays the setting contents of the recording device 1 side (that is, the contents displayed in the area E11) by default. Leave.

A setting information display area E20 is provided in the recording reservation screen. In the setting information display area E20, the EPG display time, the display channel, and the notification destination are displayed for each "recording device" and "setting". By displaying "Recording device" and "Setting" separately like this,
As with the case where not only the area E12 but also the area E11 is provided in the EPG information display area, the user can easily confirm the setting contents.

That is, the EPG display time and the like displayed together with the heading "Recording device" indicate the setting contents on the recording device 1 side at the present time. On the other hand, the EPG display time and the like displayed together with the heading "Setting" indicate the contents set by the user on this screen.

Of the items set in this way, the notification destination means the destination to which the recording apparatus 1 which has detected the change in the broadcast schedule notifies when the broadcast schedule is changed. In the program recording system in this embodiment, it is determined whether or not the broadcast schedule is changed, and the program added to the broadcast schedule is notified from the recording device 1 to the remote control device 100. When the CPU 14 executes the program, the recording device 1 is provided with the program notification means 16 as shown in FIG. The program notification means 16 notifies the added program, but if the setting of the notification destination is not fixed,
Notifications may not be delivered properly. Therefore, in the area E21 for setting the notification destination, a value of "indoor" is set in a situation where it is expected to know the change of the broadcast schedule indoors, while it is expected to be known outdoors. Under the circumstances, the value "outdoor" is set.

Therefore, when going out between 7:00 and 11:00 set as the EPG display time, it is preferable to set "outdoors". It may be set as "outdoors" when there is no plan to go out, but it is not appropriate considering the communication time and communication cost.

Here, when the user makes a recording reservation for a baseball broadcast, as shown in FIG. 14, the cursor is moved to the baseball setting area E12A on the recording reservation screen, and the setting state is changed from "OFF" to "ON". change. If the user plans to go out between 7:00 and 11:00, the user moves the cursor to the notification destination setting area E21 on the recording reservation screen and changes the setting state from "indoor" to "outdoor". change.

When the user presses the selection key K included in the input interface 104A while the cursor is on the decision button (FIG. 9, step S106), the remote control means N which has detected this indicates the contents of the change. A recording presence / absence setting command including parameters is transmitted to the recording device 1 (FIG. 9, step S107).

When the recording apparatus 1 receives the recording presence / absence setting command, the updating means 9 updates various information stored in the RAM 11 based on the contents of this command (FIG. 1).
0, steps S15 → S16). That is, the updating means 9
As shown in FIG. 15, the contents of the recording / non-recording field of the baseball record are changed from “OFF” to “ON”, and the notification destination is changed from “indoor” to “outdoor”.

When the contents of the RAM 11 are updated, the recording control means M returns a setting completion notification to the remote control device 100.
Upon receiving this notification, the remote control means N of the remote control device 100 displays a recording reservation screen on which the setting state of the recording device 1 side is reflected on the monitor 103A, as shown in FIG. 16 (FIG. 9, Steps S108 → S109).

When the recording reservation is made in this way, the recording control means M causes the information of the program stored in the management table T and the EIT which is repeatedly broadcast at a predetermined time interval.
Always check for changes to the broadcast schedule by comparing and. And
If there is no change in the broadcast schedule, 7:
The recording control means M controls the AV decoder 5A so that the writing to the HDD 8A is turned on from 00 to 9:00.

For example, since baseball has been extended for 30 minutes,
When news and news commentary are additionally broadcast between the baseball and the drama, the EIT is shown in FIG.
It includes information on four programs shown in (A) to (D).

That is, as shown in FIG.
"01" is described in the ventid field, and
“7:00” is described in the rt field, and durt
Information of a program in which "2:30" is described in the ion field and "baseball" is described in the program name field is 7:00
Indicates that the baseball broadcast was extended from 0 to 9:30.
Also, as shown in FIG. 17B, “02” is described in the eventid field, “10:30” is described in the start field, “2:00” is described in the duration field, and the program name field is described. The information of the program in which "drama" is described indicates that the drama broadcast start time has been delayed to 10:30.

As shown in FIG. 17C, eventi
Information on a program in which "98" is described in the d field, "9:30" is described in the start field, "0:30" is described in the duration field, and "news" is described in the program name field is: Indicates that news will be additionally broadcast after baseball. In addition, FIG.
As shown in (D), "9" is entered in the eventid field.
9 "is described and" 10: 0 "is set in the start field.
“0” is described and “0: is entered in the duration field.
The information of the program in which “30” is described and “news commentary” is described in the program name field indicates that news commentary is additionally broadcast after the news.

The recording control means M extracts the EIT in which the information of these programs is described from the transport decoder 4 (FIG. 10, step S18). And
When the recording control means M recognizes that the scheduled baseball broadcast schedule has been changed, the content of the duration field of the management table T changes from "2:00" to "2:30" as shown in FIG. Is changed to.

Further, in the EIT extracted as described above, information on programs that do not exist in the management table T at the present time (that is, information having an eventid of 98 and even) is included.
The information whose ntid is 99) is included.

Therefore, the recording control means M recognizes that a new program will be additionally broadcast and, as shown in FIG. 18, adds information relating to news and news commentary, which are these additional programs, to the management table T. (FIG. 10, steps S19 → S20). The recording control means M selects the communication network interface 13 because the notification destination is "outdoor", and sends a program addition notification including the contents of the management table T to the remote control device 100 (FIG. 10, step). S
21 → S22).

As a result, the remote control means N of the remote control device 100 that has received the program addition notice displays a recording reservation screen reflecting the contents of this program addition notice on the monitor 103A as shown in FIG. FIG. 9, step S11
0 → S111). However, since it is not possible for the user to predict when such a notification will be given, it is preferable to ring a ring tone when the recording reservation screen is displayed. Also, when there is a request for acquisition from the acquisition means 9,
It may be transmitted as recording reservation information.

In this way, the user recognizes that a new program will be additionally broadcast. When the user wants to record, for example, a news broadcast from the additional programs, he or she moves the cursor to the news setting area on the recording reservation screen, and as shown in FIG.
It may be changed from "F" to "ON". Then, when the user presses the selection key K while the cursor is aligned with the decision button (FIG. 9, step S112), the remote control means N generates a recording presence / absence setting command including a parameter indicating the change content, This recording presence / absence setting command is transmitted to the recording device 1 via the communication network interfaces 106 and 13 (FIG. 9, step S113).

According to the above description, since the place of use is still set to "indoor", it seems that this recording presence / absence setting command is transmitted via the infrared interface 105/12. However, here, since the recording apparatus 1 selects the communication network interface 13 to make a call (see step S21 in FIG. 10), the remote control means N receiving this call automatically sets the communication network interface 106. You have selected.

In order for the remote control means N to select the communication network interface 106 when the remote control device 100 makes a call, the user changes the use place from "indoor" to "outdoor" in advance. That is, the switching between the use locations “indoor” and “outdoor” can be freely performed as long as the screen shown in FIG. 8 is displayed.

The recording control means M which has received the recording presence / absence setting command shows the contents of the management table T shown in FIG.
When the setting completion notification is transmitted after the contents are changed to those shown in FIG. 10 (steps S23 → S24 → S25 in FIG. 10), the remote control means N which has received the setting completion notice displays the recording reservation screen shown in FIG. 22 on the monitor 103A. Is displayed (step S114 → S115 in FIG. 9). Thereby, the recording device 1 records the baseball broadcast from 7:00 to 9:30 and the news broadcast from 9:30 to 10:00 on the HDD 11 based on the remote operation received by the remote control device 100. To do.

As described above, this program recording system can surely record the program reserved for recording, and can also newly record the program additionally broadcast when the broadcast schedule is changed. Can be surely recorded.

Moreover, the user can recognize the program to be additionally broadcast, and the selection becomes easier than the case of selecting the program to be viewed from all the programs to be broadcast.

The user can use the input interface 104 of the remote control device 100 to add a recording reservation as well as change or cancel the recording reservation.

In the example of FIG. 16, the recording reservation setting for the baseball broadcast on the recording device 1 side is ON, but the user can cancel the recording reservation of this program. In this case, the user moves the cursor to the "setting" area for baseball broadcasting on the recording reservation screen and changes the setting state to "O".
After changing from "N" to "OFF", the cursor may be moved to the decision button and the selection key K may be pressed in that state.
When this is detected, the remote control means N transmits a command including a parameter indicating the content of cancellation to the recording control means M of the recording device 1. When the recording device 1 receives this command, the recording control means M turns off the recording reservation setting for the baseball broadcast information stored in the management table T based on the parameter included in the command. After this,
When the remote control device 100 receives the cancellation completion notification, the remote control means N turns off the recording reservation setting on the recording device 1 side regarding baseball broadcasting even in the recording reservation screen.

As in the case of canceling the recording reservation, the user can change the recording start time.

In the above description, when a new program is added due to a change in the broadcast schedule, the remote control device 100 is notified of the addition of the program. It is also possible to automatically schedule or record the program added to the. In this case, the recording control means M adds the information of these additional programs described in the EIT to the management table T and unconditionally turns on the recording reservation state. However,
In this case, there is a possibility that the user reserves or records a program for which the user does not feel the necessity.
Preferably transmits a message to the remote control device 100 informing that the program added to the broadcast schedule has been reserved or recorded. For example, the recording control means M automatically generates a list of information such as a title of a program for which recording reservation or recording is performed, a broadcast channel, a recording start time, and a recording time, and the communication network interface 1
Output to 3. The communication network interface 13 transmits the list to the remote control device 1 under the control of the recording control means M, and when the remote control device 1 receives the list, the list is displayed on the monitor 103A according to the control of the remote control means N. It As a result of checking this list, if the user determines that the recording reservation information needs to be updated, the user may delete or change the recording reservation as described in the first embodiment.

Further, the recording control means M may automatically make a recording reservation for only a part of the additional program. In this case, the user predefines the conditions of the additional program for which the recording control means M automatically makes a recording reservation. If there is a program satisfying this condition in the additional program, the recording control means M adds the information of the additional program to the management table T, and turns on the recording reservation setting for that. As conditions for the additional program to be automatically reserved for recording, the user must be a program that is broadcast in a specific time zone, a program that is broadcast on a specific channel, or a program with a specific name. It is possible to predetermine the condition that there is. Since a special program such as a disaster report is likely to be important to many users, it is preferable that conditions are set so that the special program is automatically scheduled for recording.

In addition, in the program recording system as described above, there is a possibility that the additional programs to be notified include programs that the user is not interested in at all.

Therefore, as shown in FIG. 13, the program recording system may include the additional program selection means 17 in the recording device 1. The additional program selecting means 17 is also realized by the CPU 14 executing the program.

The additional program selecting means 17 selects a program from the programs added to the broadcast schedule, here, based on the recording reservation information.

The recording control means M controls the information on the programs stored in the management table T and the EIT which is repeatedly broadcast.
It is recognized that a new program has been added by comparing the information of the program included in the additional program selection means 17
Notify additional programs to.

The additional program selection means 17 is the recording control means M.
When the additional program is notified from, the information of the program whose recording reservation is ON is taken out from the management table T.

The program information described in the EIT may include detailed information such as the program title, genre, brief description, and creator in addition to the above-mentioned program title and broadcast time, and additional program selection. The means 17 extracts these pieces of information.

Further, the additional program selecting means 17 extracts the information of the additional program from the updated EIT, and compares the information of the additional program with the information of the program whose recording reservation is ON. As a result of this comparison, if there is a relationship such that the information of both programs matches, the additional program selecting means 17 selects the additional program.

For example, if there is a performer of a program whose recording reservation is ON among the performers of the additional program, the additional program selecting means 17 selects the additional program. As described above, the case where the information of both programs coincides includes not only the case where the information of both programs completely coincides but also the case where they partially coincide.

Further, the additional program selecting means 17 uses not only the program for which the recording reservation is ON but only the recorded program information of the already recorded program, or both the recorded program information and the recording reservation information. Then, a program may be selected from the additional programs.

The recorded program information is the same as the recording reservation information on the already recorded programs, and the recording means 5
Records the recorded program information in the HDD 8A together with the program. In addition to the EIT information, the recording means 5 may record the recording bit rate for recording a program, the capacity consumed for recording the program, etc. in the HDD 8A as recorded information.

The additional program selecting means 17 extracts the recorded program information from the HDD 8A and compares the recorded information with the additional program information, as with the program information for which the recording reservation is ON.

If the recorded program information relating to a plurality of programs is stored in the HDD 8A, the additional program selecting means 17
Can also select programs using the statistics of recorded information about each program.

For example, if a plurality of programs already recorded include a predetermined number or more of sports programs and news programs,
The additional program selecting means 17 may select only sports programs and news programs.

Further, the additional program selecting means 17 uses only statistics about the information of the programs already recorded, and selects the programs based on the statistics and the programs whose recording reservation is ON. Good.

It is assumed that a plurality of programs already recorded include a predetermined number or more of sports programs and news programs, and a news program is notified as an additional program while the recording reservation of the sports program is ON. The additional program selecting means 17 selects a new news program even if the recording reservation of the news program is not ON.

The program thus selected is notified from the additional program selecting means 17 to the program notifying means 16. The program notification unit 16 notifies the remote control device 100 of only the selected programs as the programs added to the broadcast schedule.

As a result, the monitor 103A of the remote control device 100 displays a notification screen showing only the selected program. Since the interest of the user is naturally reflected in the selected program, in this case, the user does not need to perform troublesome registration in order to narrow down the notified programs.

If the recording reservation information and the recorded program information are stored in a non-volatile memory built in the remote control device 100 or a removable memory card, the additional program selection means 17 of the recording device 1 can be used. Alternatively, remote control device 100 may select a program from the additional programs based on the stored information. (Embodiment 3) When the recording reservation of the program is added as described above, the recording medium 8 on which the program is recorded does not always remain for the programs for which the recording reservation is added. Therefore, the remote control device 100 according to the present embodiment.
23 includes a comparison unit 110, as shown in FIG. The comparing means 110 compares the recording capacity required for recording the program to which the recording reservation is added with the remaining capacity of the recording medium 8 in which the program is recorded, and the comparison result is displayed by the displaying means 103.
To display.

In this embodiment, the recording control means M is
It manages the remaining capacity of the recording medium 8. This remaining capacity is calculated from the total capacity of the recording medium 8 as the capacity of the area where the program is recorded (hereinafter, recorded capacity) and the capacity consumed for recording the program already reserved for recording (hereinafter, allocated capacity). Is subtracted. Here, the allocated capacity is 2.8 Gbytes and the remaining capacity is 10.1 Gbytes.
Suppose The recording control means M is the remote control device 100.
When the recording reservation information is transmitted to, the information indicating the remaining capacity of the recording medium 8 is also transmitted.

When the remote control device 100 receives this information, the comparison means 110 acquires from the remote control means N the recording time and the recording bit rate of the program for which the recording reservation is added.

The recording time of the program for which the recording reservation is added is 2
Time, and the recording bit rate is 9.2 Mbps (10
24M = 1G). In this case, the capacity consumed for recording the program for which the recording reservation is added is about 8.1 Gb.
It becomes y tes. The comparison means 110 compares this capacity with the received remaining capacity and, for example, displays the difference between the two on the display means 103 as a comparison result.

In this case, the difference between the two is 2.0 Gbyte.
Therefore, even if all the programs for which recording reservations are made are recorded, including the programs for which recording reservations are added, the capacity of the recording medium 8 remains. In this way, by confirming the display of the comparison result, the user can easily determine whether or not the recording medium 8 has a sufficient capacity by using the remote control device 100.

If it is confirmed that the remaining capacity of the recording medium 8 is sufficient, the user may instruct the remote control device 100 to update the recording reservation information. The remote control means N sends an update request to the recording device 1 according to the user's instruction. When the recording device 1 receives the update request, the updating means 9 adds the recording reservation according to the user's instruction. Also, the recording control means M adds the capacity of the program to which the recorded program has been added to the allocated capacity, and further updates the remaining capacity. here,
The capacity of the program to which the recorded program is added is 8.1 Gbyte.
Therefore, the assigned capacity is 10.9 Gbytes. As a result of the addition, the allocated capacity is 2.8 Gbyte.
Since s changes to 10.9 Gbytes, the remaining capacity is updated to 10.1 Gbytes to 2.0 Gbytes.

Each time the program reserved for recording is actually recorded, the recording control means M subtracts the capacity of the recorded program from the allocated capacity and adds it to the recorded capacity. As described above, the remaining capacity = total capacity-recorded capacity-assigned capacity has a relationship, so that the remaining capacity does not change even when a program reserved for recording is actually recorded. When all the programs reserved for recording are recorded, the allocated amount is 0 Gbytes.

As described above, in the present embodiment, as long as the recording device 1 transmits the remaining capacity to the remote control device 100, the remote control device side can perform calculation for the user to confirm the capacity. it can. Not only the remaining capacity,
The remote controller 1 also has the capacity required to record additional programs.
00 may be transmitted to the recording device 1. In this case, the comparison means 110 may use the capacity of the received additional program as the capacity of the program to which the recording reservation is added, without calculating the capacity of the program to which the recording reservation is added. When there are a plurality of additional programs, the recording control means M calculates the capacity of each program, and the comparison means 110 may select one of them according to the user's instruction.

It is assumed that after all the programs reserved for recording have been recorded in this way, a recording reservation for a program for 2 hours is added. The recording bit rate for recording this program is 9.2M
If it is bps, since the remaining capacity is 2.0 Gbytes, the value obtained by subtracting the capacity of the program for which the recording reservation is added from the remaining capacity is −6.1 Gbytes.

Also in this case, the comparison means 110 displays on the display means 103 a value obtained by subtracting the capacity of the program for which the recording reservation is added from the remaining capacity as the comparison result. The calculation result is not displayed as the comparison result, but the comparison means 1
Reference numeral 10 denotes a display means 1 as a comparison result, which is a symbol such as “◯” or “×” indicating whether or not the recording medium 8 has a sufficient capacity.
03 may be displayed.

By checking this display, the user can easily know that the capacity of the recording medium 8 is insufficient for recording the program to which the recording reservation is added.

When the comparison result shows that the capacity is insufficient, in order to record all the parts of the program for which the recording reservation is added, the remaining capacity of the recording medium is increased or the remaining capacity of the program is increased. It is only necessary to reduce the capacity consumed for recording.

Therefore, the program recording system includes the bit rate instructing means 111 and the deleted program instructing means 112. The user uses the bit rate instruction means 111 to
By suppressing the capacity consumed for recording the program for which the recording reservation is added, the consumed capacity can be made less than or equal to the remaining capacity. For example, by using the bit rate instructing means 111, the recording bit rate is from 9.2 Mbps to 4.0 Mbps.
When changed to ps, the capacity consumed for recording the program for which the recording reservation is added is 3.5 Gbytes. Therefore, when a program is recorded at this recording bit rate, the remaining capacity becomes -1.5 Gbytes. If the user who confirms this reduces the setting value of the recording bit rate to 2.0 Mbps, the capacity consumed for recording the program for which the recording reservation is added becomes 1.8 Gbytes. Therefore, when a program is recorded at this recording bit rate, the remaining capacity is 0.
It becomes 2 Gbytes. By confirming the display of the comparison result in this way, the user can adjust the recording bit rate so that all the programs to which the recording reservation is added can be recorded.

The recording bit rate thus adjusted is included in the update request when the remote control means N makes a request to update the recording reservation information of the corresponding program. The recording means 5 has an AV encoder in addition to the AV decoder,
Under the control of the recording control means M, recording is performed at the recording bit rate included in the updated recording reservation information. As a result, even if the remaining capacity of the recording medium 8 is insufficient to record the program for which the recording reservation is added at the time when the recording reservation is added, all the programs can be recorded.

Further, the user is instructed to delete program 112.
By deleting the recorded program using, the capacity consumed for recording the program to which the recording reservation is added can be secured in the recording medium.

In this embodiment, the remote control device 100 is used.
In addition to the recording reservation information, all the program information that the user has instructed to record is transmitted from the recording apparatus 1. When the user deletes the recorded program, for example, as shown in FIG. A recorded program list including information such as recording date, size, recording bit rate, etc. for each program is displayed on the display unit 103.

In this recorded program list, the remaining capacity of the recording medium 8 is also displayed. In this example, the remaining capacity of the recording medium 8 is 6.5 Gbytes, and the capacity consumed for recording the program for which the recording reservation is added is 8.1 Gbyte.
If s, the capacity will be insufficient. When the capacity is insufficient, the user may select an unnecessary program from the recorded programs by using the delete program instructing means 112 and delete the program. Here, the user is the program ID “103”.
, The remote control means N requests the recording device 1 to delete the selected recorded program. When the recording device 1 receives this request, the corresponding program is deleted from the recording medium 8. As a result, the remaining capacity of the recording medium 8 becomes 8.3 Gbytes. Therefore, it is possible to record the entire recording of the program to which the recording reservation is added.

Although it has been explained that the programs to be deleted contained in the recorded program list are basically all the program information that the user himself has instructed to record, this deletes the programs recorded by others. This is because the user usually does not have the right. The program to be deleted may be specified by the recording control means M based on the user ID added to the information of each program or the deletion permission flag added to the program permitted to be deleted in advance. For example, if the remote control device 100 is equipped with a memory card for storing the user's ID, the recording control means M extracts only the program corresponding to the ID received from the remote control device 100 from the recorded programs.

Further, when the capacity of the recording medium becomes insufficient due to the new recording reservation of the program, the recording control means M automatically deletes the program already recorded on the recording medium as appropriate. By doing so, it is possible to eliminate the lack of capacity.

In this case, the recording control means M records on the basis of the recording time of the recording-reserved program, the recording bit rate for recording this program, and the remaining capacity of the recording medium in which the recording-reserved program is recorded. It is determined whether or not to delete the program recorded on the medium. The determination of the deleted program is performed, for example, when the recording device 1 receives an update request from the remote control device 100.

Here, in the example of FIG. 14, the user uses the input interface 104A of the remote control device 100 to change the recording reservation setting of the drama from "OFF" to "ON" and adds the recording reservation of the drama. I shall.

Thus, the user inputs the contents of the recording reservation (FIG. 25, S200), and when the remote control means N detects this input operation, the remote control means N uses the infrared interface 105 or the communication network interface 106. Then, the command for requesting the recording reservation including the parameter indicating the addition of the recording reservation is transmitted to the recording device 1.

When the recording device 1 receives this command (FIG. 25, S300), the recording control means M acquires the recording time of the program to which the recording reservation is added from the parameters included in the command. Furthermore, the recording control means M acquires the current recording bit rate setting and the remaining capacity of the HDD 8A. The recording control means M calculates the consumed capacity consumed for recording the program, for example, based on the setting of the recording time and the recording bit rate of the program to which the recording reservation is added, and the consumed capacity and the remaining capacity of the HDD 8A. Compare the magnitude relationship with. Based on the comparison result, the recording control means M
It is determined whether or not the program recorded in the HDD 8A is deleted (FIG. 25, S301).

When the consumed capacity is larger than the remaining capacity of the HDD 8A, the determination result indicates that the program recorded in the HDD 8A is deleted. When the consumed capacity is less than or equal to the remaining capacity of the HDD 8A, the determination result is stored in the HDD 8A. Indicates that the recorded program is not deleted.

If the determination result indicates that the program recorded on the recording medium is deleted, the recording control means M selects from among the programs recorded on the recording medium,
The deleted program is selected based on a predetermined condition (FIG. 25, S302).

The predetermined condition is, for example, the condition that the program is the earliest recorded one of the programs permitted to be deleted.

In order to select the program to be deleted, the recording control means M
Refers to the management table of recorded programs. The recorded program management table includes, for example, as shown in FIG. 26, a program ID, a program title, a channel, a recording date and time, a start address and an end address.

In the example of FIG. 26, since "Baseball □□□ Battle" is the oldest recorded program, the recording control means M is used.
Selects this recorded program as a deleted program and calculates the occupied capacity of the recorded program in the HDD 8A based on the start address and the end address.

The recording control means M adds the notified occupied capacity and the remaining capacity of the HDD 8A to calculate the remaining capacity after the deletion of the selected deleted program. The recording control means M compares the remaining capacity after deletion with the consumed capacity of the program reserved for recording, and determines deletion based on the comparison result. The above-described procedure by the recording control means M is repeated until the determination result indicates that the program recorded in the HDD 8A is not deleted.

Even if all the recorded programs which are permitted to be deleted are selected as the deleted programs by repeating the procedure as described above, if the remaining capacity after the deletion is smaller than the consumed capacity of the program reserved for recording, the recording is performed. The control means M determines that it is impossible to record the program reserved for recording. on the other hand,
When the remaining capacity after deletion becomes equal to or larger than the consumed capacity of the program reserved for recording, the recording control means M determines that the program reserved for recording can be recorded.

In this way, it is determined whether or not the program reserved for recording can be recorded (FIG. 25, S).
303), if it is determined that the program for which the recording reservation is requested can be recorded, the recording control means M updates the management table T (FIG. 25, S304) and sets the information of the program to the management table T. And set the recording reservation setting for that information to ON.

After the management table T is updated, or when it is determined that the program requested to be reserved for recording cannot be recorded, the recording control means M causes the infrared interface 12 to operate.
Alternatively, the communication network interface 13 is used to transmit to the remote control device 100 a notification indicating that recording reservation is completed or recording reservation is impossible.

The actual deletion of the selected deleted program is preferably performed immediately before the recording start time of the recording-reserved program after the completion of the recording reservation notification.

This is to prevent the deleted program from being already lost when the user cancels the recording reservation.

When the recording control means M deletes the deleted program immediately before the recording start time (FIG. 25, S305), the recorded program management table is updated accordingly (FIG. 25,
S306).

When the current time reaches the recording start time, the recording control means M starts recording the program reserved for recording according to the program information stored in the management table T and the like (FIG. 25, S307).

When the recording of the reserved program is finished,
The recording control means M deletes the information of the program just recorded from the management table T and adds the corresponding information to the recorded program management table (FIG. 25, S308). (Embodiment 4) In this embodiment, as shown in FIG. 27, remote control device 100 of the program recording system is provided with personal information storage means 113 for storing personal information of the user. At the time of the update request, the remote control means N reads the personal information identifying the user from the personal information storage means 113 and includes the personal information in the update request. The personal information that identifies the user may be the telephone number of the mobile phone or the ID unique to the user.

When the recording device 1 receives the update request including such personal information, the recording device 1 can manage the recording reservation information to be updated and the personal information in association with each other.
Based on the personal information, it is possible to control the reproduction display of the recorded program or the marked image.

The playback / display control will be described using the recording / playback system shown in FIG. This recording / reproducing system includes a mobile phone 500 and a recording / reproducing device 600.

And a remote controller function unit 500B. In the telephone function unit 500A, the telephone number storage unit 501 stores the telephone number of the mobile phone 500. The personal identification number storage unit 502 stores the personal identification number of the mobile phone 500. The input unit 503 is used to operate the mobile phone 500. The display unit 504 displays information for controlling the recording / reproducing device 600. Also, the remote control function unit 5
In 00B, the user certifying unit 511 determines that the mobile phone 5
The person who operates 00 is specified. External device control unit 512
Controls an external device from the mobile phone 500. The transmission / reception unit 513 transmits / receives a command for controlling an external device.

In the recording / reproducing apparatus 600, the transmitting / receiving section 621 transmits / receives commands to / from the mobile phone 500. The operator identifying unit 622 identifies a person who operates the recording / reproducing apparatus 600 from the mobile phone 500 based on the telephone number and the personal identification number sent from the mobile phone 500. The program registration unit 623 records the person who performed the recording operation in the recording information management table 630. The program search unit 624 searches for a program recorded by the person who performed the reproduction operation. Marker registration unit 626
Records the person who performed the marker registration operation in the marker information management table 631. The marker search unit 627 searches for an image marked by the person who has operated the marker. The scene reproduction unit 628 reproduces the scene selected by the person who performed the marker reproduction operation.

Further, in the user management table 629 of the recording / reproducing apparatus 600, information of a person who operates using the mobile phone 500 is registered in advance in the format of FIG.

After that, when the user presses the reproduction equivalent button of the mobile phone 500, the mobile phone 50
0 creates a transmission command (OPC = 2) shown in FIG. 41 for instructing the recording / reproducing apparatus 200 to reproduce. In the list shown in FIG. 38, the command for instructing "playback" has no operand, but in this case, the date of birth is set in the operand of the command. Mobile phone 500
Transmits this command to the transmission / reception unit 513 of the mobile phone 500.
To the recording / playback apparatus 600.

The transmitting / receiving unit 621 of the recording / reproducing apparatus 600 is
When the transmission command transmitted from the mobile phone 500 is received, the operator identifying unit 622 searches the user management table 629 of FIG. 40 with the subscriber identification information included in the received command. As a result of the search, if the password of the operator ID in the user management table 629 matches the received password, the operator identifying unit 622 issues a reproduction command to the program searching unit 624.
And the recording / playback apparatus sends the transmission command (OP
"0 (= Authentication OK)" is set in the operand of C = 9), and the command is transmitted from the transmission / reception unit 21 to the mobile phone 10.
Send to 0.

If the password in the user management table 629 and the received password are different, the recording / reproducing apparatus sets "1 (= authentication NG)" in the operand of the transmission command (OPC = 9) in FIG. Then, the command is transmitted from the transmission unit 621 to the mobile phone 500.

The program search unit 624 is the operator specified by the operator specifying unit 622 and is the recording information management table 630 of FIG.
To search. In addition, the program determination unit 632 determines that the mobile phone 5
Based on the date of birth of the operator in the command received from 00, it is determined whether the specified operator is a minor. When it is determined that the identified operator is not a minor, the determination result is from the program determination unit 632 to the program search unit 6
24 will be notified.

In this case, the program search section 624 extracts all the program titles that the operator matches and creates a specific operator recording title list table.

On the other hand, when it is determined that the identified operator is a minor, the program determination unit 632 determines that the program search unit 62
Among the programs searched for by No. 4, the non-permitted program belonging to the category not permitted to the minor is determined, and the program is notified to the program search unit 624. The program search unit 624 extracts the programs excluding the non-permitted programs from the programs having the same operator for recording and reproduction, and creates a specific operator program title list table.

After that, the recording / reproducing apparatus 600 creates the transmission command (OPC = 3) shown in FIG. 41, and transmits the command from the transmission / reception unit 621 to the mobile phone 500.
When the transmitting / receiving unit 513 of the mobile phone 500 receives the command, the mobile phone 500 displays the program title of the operand and the recording date on the display unit 504, as shown in FIG. When the operator selects a program to be reproduced from the displayed program titles, the mobile phone 500 transmits the selected program ID from the transmitting / receiving unit 513 to the recording / reproducing device 600 (OPC = 4). The transmitting / receiving unit 21 of the recording / reproducing apparatus 600 receives the command transmitted from the mobile phone 500, and sends the program ID selected for reproduction to the program reproducing unit 625. The program reproducing unit 625 reproduces the program of the title selected from the specific operator recording title list table (FIG. 34).

In such a recording / playback system, even if an operator who is a minor records a program that is not permitted by the minor, the minor is selected from among the options of the programs that the operator wants to reproduce. The program cannot be played because the programs that are not allowed by are excluded. Therefore, viewing of such programs can be restricted.

In the above description, the viewing of the recorded program by reproduction is restricted, but the present invention is not limited to this. If the operator is a minor, the recording / playback apparatus 600 may limit recording of the program itself.

In addition, for example, the recording / reproducing apparatus 600 is equipped with an EPG.
If the display of information is requested, the recording / playback apparatus 600
May control to select a program for which the EPG information is displayed.

[0209] In this case, when it is determined that the operator is a minor, the recording / reproducing apparatus 600 selects a program that is not permitted by the minor from the EPG information, and selects the selected program. Do not display information. As a result, when the operator is a minor, selection of programs to be viewed using EPG information is limited.

[0210] Further, it is possible to restrict viewing without using the personal information stored in the IC card 514. For example, each operator ID in the user management table 629
May be associated with a flag indicating the presence or absence of parental control.
In this case, if the flag associated with the operator ID of the reproduction operator indicates that there is a viewing restriction, the program determination unit 632 determines that the program searched by the program determination unit 624 is assigned to a specific section. The program to which the program belongs is determined, and the program search unit 624 is notified of the program. The program search unit 624 extracts the programs excluding the notified program from the programs having the same recording and reproducing operators, and creates a specific operator title list table. (Embodiment 7) When the additional program selecting means 17 in the embodiment 2 selects a program from the additional programs based on not only the recording reservation information but also the recorded program information,
The number of programs that are normally selected is increased as compared with the case where the programs are selected based on the programs reserved for recording. Further, for example, when the recording device 1 is shared by a family, based on a program recorded by another person in the family or scheduled for recording,
The program may be selected.

Therefore, the operator may be specified and the program may be selected based on the operator, as in the recording / reproducing system according to the fourth and fifth embodiments.

Therefore, in the recording system according to the seventh embodiment, as shown in FIG. 44, the recording device 1 manages the history of information for specifying the operator who has performed the recording or recording reservation operation. 18 is provided.

Further, the remote control device 100 uses a portable telephone to which an IC card 110 storing subscriber identification information and the like is detachably mounted.

For example, it is assumed that each family member who shares the recording device 1 owns a different mobile phone and uses each mobile phone as the remote control device 100. In this case, the IC mounted on each remote control device 100
The subscriber identification information stored in the card 114 will be used as information for identifying the operator.

In this recording system, the history management means 18 manages the same user management table and recording operator management table as shown in FIG. As shown in FIG. 45, the recording operator management table stores the ID of the recorded program and the ID of the operator who performed the operation of recording the program in association with each other. The ID of the recorded program corresponds to the ID of the recorded program, and the ID of the operator and the information of the recorded program are associated with each other via the ID of the program. The management table T also stores an operator ID for each program identification ID, as shown in FIG. The recording operator management table stores the operator ID of the person who performed the recording operation, whereas the management table stores the operator ID of the person who performed the recording reservation operation.

Then, the additional program selecting means 17 selects a program from the additional programs based on the history managed by the history managing means 18.

When it is recognized that a new program has been added, the additional program selection means 17 acquires from the management table T the operator ID associated with the program for which the recording reservation is ON, for example. In the example of FIG. 46, the recording reservation is ON.
The program that is marked is only the baseball broadcast, and the operator ID associated with this program is "1". When the additional program selection unit 17 acquires the operator ID for the program reserved for recording, the additional program selection unit 17 notifies the history management unit 18 of the operator ID. When the history management means 18 is notified of the operator ID, the program ID corresponding to the notified operator ID.
From the recording operator management table. In the example of FIG. 45, the acquired program IDs are “1” and “2”.
The acquired program ID is notified from the history management means 18 to the additional program selection means 17. When the program ID is notified, the additional program selecting means 17 acquires only the recorded program information identified by this program ID. Assuming that information corresponding to the recording information management table shown in FIG. 43 is stored as the recorded program information, the additional selected program means 1
The information of the programs acquired by 7 is “News ○○○” and “△
△ News ”information only. The additional selection program means 17 does not acquire the information of the “baseball □□□ battle” recorded by another operator.

As a result, the additional program selecting means 17 causes the additional program to be based on only the three programs for which the operator is the same, that is, the baseball broadcast for which recording is reserved, and the information of "News ○○○" and "△△ news". You will be selecting a program from.

As a result, even if the recording apparatus 1 is shared by a plurality of people, the operator's individual interest is reflected in the selected program.

As described in the third embodiment, the operator deletes the recorded program recorded in the recording medium in order to secure the capacity for recording the program to which the recording reservation is added in the recording medium. be able to.

When the recording apparatus 1 is shared by a plurality of people, the list of recorded programs shows not only the programs recorded by the operator himself but also the programs recorded by other operators. Is also included.

It is difficult for the operator to judge whether or not a program which the operator has not performed a recording operation may be deleted. For this reason, when the operator himself / herself searches for the recording operation in the list of recorded programs, it takes time and effort for the operator to select the program to be deleted. Also, even if the operator does not intend to delete the program that has not been recorded, if the program is included in the list of recorded programs,
The operator may erroneously delete a program that another operator has recorded.

Therefore, the remote control means N uses the monitor 103.
Of the programs recorded in the HDD 8A, only the programs that the operator of the mobile phone has performed the operation of recording in the HDD 8A may be displayed in A.

In this case, when the recording apparatus 1 receives the command requesting the information of the recorded program from the mobile telephone, the recording control means M acquires the ID of the operator corresponding to the program recorded in the HDD 8A, The operator ID is added to the information of each recorded program, and the information is transmitted to the mobile phone. When the mobile phone receives the information on the recorded program to which the operator's ID is added, the remote control means N causes the IC card 114 to read the I
D is acquired, and the information of the recorded program with the same ID is extracted from the received information. The remote control means N creates a list of recorded programs only from the extracted information of the recorded programs, and displays the list of recorded programs on the monitor 103A.

With this, the operator can easily select the program to be deleted, and there is no fear of accidentally deleting the program recorded by another person.

When the remote control means N operates as the additional program selecting means 17, the recording apparatus 1 not only notifies the additional programs, but also adds the operator ID to the information of each recorded program. If the information is transmitted to the remote control device 100, the remote control means N may select a program from the additional programs based on the operator's ID, similar to the additional program selecting means 17 in this embodiment. it can.

Further, the remote control means N may display on the monitor 103A only the programs which have been previously permitted to be deleted among the programs recorded in the HDD 8A.

In this case, the user uses the input interface 104A to select a program to be deleted from the list of recorded programs in advance. When the user selects a program,
The remote control means M creates a command instructing deletion permission of the selected program, and sends the command to the recording device 1. When the recording device 1 receives the command, the recording control means M adds the recorded information of the program permitted to be deleted to the recorded information.
Add a flag indicating that deletion is allowed.

[0229] When the mobile phone receives the recorded information,
The remote control means N creates a list of recorded programs only from the recorded information to which the flag is added, and displays the list of recorded programs on the monitor 103A.

Also in this case, the operator can easily select the program to be deleted, and it is possible to avoid the risk of carelessly deleting the recorded program. (Embodiment 8) In the above-mentioned Embodiment 3, the recording control means M is based on the condition that it is the oldest recorded program among the programs permitted to be deleted.
The program to be deleted has been selected, but the program is not limited to this.

For example, there is a condition that the person who has performed the operation of recording the program on the recording medium and the person who has performed the operation of the recording reservation are the corresponding programs, and the condition that the program is a deletion-permitted program whose deletion is permitted. On the basis of this, the recording control means M may select the deleted program.

In the eighth embodiment, the deleted program is selected based on the condition that the operator who has performed the recording reservation operation complies with the deletion level of the program for which the recording operation has been performed.

The recording system according to the eighth embodiment, as shown in FIG.
A mobile phone to which the IC card 110 is detachably mounted is used.

Here, for the sake of convenience, there are two mobile phones used as the remote control device 100, and the IC card 110 mounted on one mobile phone has a user ID of “0” and the other mobile phone. The user ID "1" is stored in the IC card 110 attached to the.

The deletion level is set by two users respectively using these mobile phones, or the recording device 1 sets a default value.

The deletion level is made up of three levels, for example, a deletion target level, a deletion permission level and a non-deletion level. The deletion target level is a level indicating that the recorded program is deleted from the recording medium, and the deletion permission level is a level indicating that the recording control means M may select the recorded program as the deleted program. Yes, the unerasable level is a level indicating that the recording control means M is prohibited from selecting a recorded program as a deleted program.

In the eighth embodiment, for example, a recorded program management table as shown in FIG. 47 is prepared, and this recorded program management table is provided for each program with the user ID of the operator who recorded the program. , The recording time of the program and the deletion level are associated with each other.

The value "0" of the deletion level indicates the deletion target level, and the value "2" indicates the non-deletion level. Although not shown in FIG. 47, the value “1” indicates the deletion permission level.

The user ID "10" shown in FIG.
The value of "0" indicates that the value of the recording time corresponding to this value is the time when the program can be recorded on the recording medium. In this example, the remaining time that can be recorded on the recording medium is 2.5 hours.

Further, in the management table T, as shown in FIG. 48, each program is associated with the user ID of the operator who has performed the recording reservation operation for the program.

The user ID included in the recorded program management table or the management table T is I when each user performs recording or recording reservation operation using his or her own mobile phone.
It is taken out from the C card 114 and transmitted from the mobile phone to the recording device 1.

A procedure for a user to make a recording reservation for such a recording device 1 by using a mobile phone (remote control device 100) is as shown in FIG.

For example, in step S200, when the user adds a program to be reserved for recording, as shown in FIG. 50, by using a mobile phone equipped with an IC card storing a user ID of "1". The mobile phone transmits to the recording device 1 a command requesting a recording reservation including a parameter indicating the user ID and additional contents.

When the recording device 1 receives this command,
The recording control means M acquires the recording time of the program for which the recording reservation is added from the parameter included in the command (FIG. 25, S300). In the example of FIG. 50, the recording time of the program to which the recording reservation is added is 4 hours. Further, the recording control means M acquires from the management table T the recording time corresponding to the user ID having the value “100”, that is, the recordable time of the recording medium. In the example of FIG. 48, the recordable time is 2.5 hours. The recording control means M, based on the recording time and the recordable time of the program to which the recording reservation is added,
It is determined whether or not the program recorded in the recording medium is deleted (FIG. 25, S301).

In this example, since the recording time of the program to which the recording reservation is added is longer than the recordable time, the recording control means M decides to delete the program recorded in the recording medium. When the deletion is determined, the recording control means M acquires the user ID from the parameter included in the command and selects the deleted program from the recorded programs associated with the user ID (FIG. 25). , S30
2). For this selection, the recording control means M refers to the recorded program management table, but in the example of FIG.
There is no program associated with the user ID with the value "1" and the deletion level with the value "1". In this case, there is no recorded program that can be deleted.

Therefore, the recording control means M refers to the recorded program management table and acquires the recording time of the program associated with the deletion level of the value "0" or "1",
When there are a plurality of programs that satisfy the condition, the recording times of those programs are summed up. The recording control means M compares the recording time or an added value obtained by adding the total value thereof and the recordable time with the recording time of the program reserved for recording, and based on the comparison result, recording of the program reserved for recording. It is determined whether or not is possible (S303 in FIG. 25).

If the added value is equal to or longer than the recording time of the program reserved for recording, it is determined that the program reserved for recording can be recorded, and the recording control means M, as shown in FIG. Is updated (FIG. 25, S304).

On the other hand, when the added value is smaller than the recording time of the program to be reserved for recording, the recording control means M notifies the portable telephone that the recording reservation is impossible, which indicates that the recording reservation cannot be made.

When it is notified that the recording reservation cannot be made, the user needs to change the setting of the deletion level in order to record the program for which the recording reservation was made on the recording medium.

In this case, when the user gives an instruction to display the contents of the recorded program management table of the recording apparatus 1 to the mobile phone (FIG. 50, S400), the mobile phone uses the IC
A command including a user ID stored in the card 114 and requesting display contents is transmitted to the recording device 1. When the recording device 1 receives this command (FIG. 50, S450), the recording control means M extracts the information of the recorded program in the recorded program management table (FIG. 50, S451). At this time, the recording control means M uses the user ID included in the command.
You may extract only the information of the program corresponding to. When the information is extracted from the recorded program management table, the recording device 1
Transmits the information of the extracted recorded program to the mobile phone (FIG. 50, S452). When the mobile phone receives the information of the recorded program, a deletion level setting screen as shown in FIG. 51 is displayed on the monitor of the mobile phone.

When the user refers to this deletion level setting screen and decides the program to be deleted among the programs that he or she has recorded, the value of the deletion level of the program is changed from "2" to "0". Input to the mobile phone (Fig. 5
0, S401). Here, for example, as shown in FIG. 53, it is assumed that the deletion level of the program name “3” is changed to “0” on the deletion level setting screen. When the input content is determined by the user's operation, the mobile phone transmits to the recording device 1 a command requesting a setting change of the deletion level including a parameter indicating the change content.

When the recording apparatus 1 receives this command (FIG. 50, S453), the recording control means M updates the recorded program management table on the basis of the contents of change indicated by the parameter included in the command (FIG. 50, S453). S454).
After that, the recording device 1 notifies the mobile phone that the setting is completed (FIG. 50, S455).

As a result, the deletion level of the recorded program management table is changed as shown in FIG. The value of the deletion level corresponding to the program ID of "3" is "2"
Has been changed to "0".

By thus setting the deletion level for the program as the deletion target level, the total value of the recording times corresponding to the deletion level of "0" is 2
Time + 2 hours = 4 hours, and the added value of this value and the recordable time is 6.5 hours. Since this added value is larger than the recording time of the program reserved for recording, in this state, the recording control means M determines that the program reserved for recording can be recorded.

[0255]

As described above, according to the present invention, it is possible to confirm from the display information displayed on the display means of the remote control device that the recording reservation information differs from the broadcast schedule information. It is possible to easily and surely notice the change in the broadcast schedule and update the recording reservation information in accordance with the change.

When the display information includes information for displaying the program whose broadcast schedule has been changed among the programs reserved for recording in an identifiable manner, the user immediately recognizes the program whose broadcast schedule has been changed. It is possible to specify, and it is not necessary to confirm the recording reservation information for all the programs reserved for recording.

Further, by notifying the remote control device of the program selected by the recording device based on at least one of the recorded program information and the recording reservation information, the program of interest to the user can be obtained without the user being bothered. Can be notified to the user.

If the control means of the recording control device automatically schedules or records the program added to the broadcast schedule, the period from the addition of the program to the broadcast is short, and the user can Even if you did not immediately know about the addition, you can avoid missing the program.

In this case, if the recording device sends a message notifying that the program added to the broadcast schedule has been reserved or recorded, the user can confirm that the program has been added. You can, and you can see if unnecessary programs are recorded.

If the recording device displays on the display means the comparison result of the recording capacity required for recording the program to which the recording reservation is added and the remaining capacity of the recording medium on which the program is recorded, Can determine from the displayed comparison result that the remaining capacity of the recording medium is insufficient for recording the program. When the user determines that the remaining capacity is insufficient, the user can record the program by deleting the program already recorded on the recording medium or changing the recording bit rate of the program to which the recording reservation is added. It is possible to appropriately secure the recording capacity for the recording, and to prevent only a part of the program from being recorded or the recorded program from being inadvertently overwritten.

Further, when the update request made by the remote control means of the remote control device to the recording device includes the personal information for specifying the user of the remote control device, if the personal information included in the update request is used, The recording device can identify the user of the remote control device and can control recording and reproduction based on the identification result.

In this case, the recording apparatus is capable of reproducing and displaying the program by filtering and displaying the recorded program or filtering and displaying the marked image based on the personal information. Even when shared by a plurality of people, the user can easily select a program or a marker to be reproduced and displayed from the programs that the user himself has performed the recording operation.
