BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a video recording apparatus and a video recording method according to the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram of a video recording apparatus for explaining an embodiment of the video recording apparatus and the video recording method according to the present invention. This device is an example in which the present invention is applied to a tuner compatible with digital broadcasting such as BS digital having a built-in hard disk drive (hereinafter referred to as HDD) that is a large-capacity storage medium.

Reference numeral 1 is an antenna for receiving a digital broadcasting signal such as BS digital, 2 is a tuner for receiving a signal from the antenna 1, and a tuner for selecting a desired channel from the antenna 3 is obtained from the tuner 2. It is a decoder that decodes a packet of a transport stream (hereinafter referred to as TS). Reference numeral 4 is a video processing circuit for performing format conversion of the video signal decoded by the decoder 3 into an appropriate picture frame, and reference numeral 5 is a cathode ray tube for image display. Also, 6
Is a HDD, which is a large-capacity recording medium for mainly recording the TS output from the decoder 3, and 7 is a microprocessor unit (hereinafter referred to as MPU) that controls the entire apparatus.
Is. A RAM 8 for temporarily recording various data, a ROM 9 capable of recording data in a non-volatile manner, an infrared receiving section 11 for receiving an infrared signal from a remote controller 10 and a keyboard 12 are connected to the MPU 7 via a bus line 13. Has been done.

Next, the operation of this apparatus will be described. A digital broadcast signal such as BS digital received by the antenna 1 is input to the tuner 2 to select a desired channel, and the TS packet obtained here is a command from the MPU 7 that controls the entire apparatus. It is received and decoded by the decoder 3 which decodes the TS and further decodes the MPEG signal. The video signal decoded by the decoder 3 is format-converted into an appropriate image frame by the video processing circuit 4, and finally displayed on the screen of the cathode ray tube 5.

On the other hand, the TS decoded by the decoder 3
When the data is recorded on the HDD 6, the TS input to the decoder 3 is converted into a special format such as compression or encryption, and H
It will be recorded in DD6. In addition, the decoder 3
Has a dual role of displaying video and recording to the HDD 6, and may be divided into two or more chips. Further, the HDD 6 is equipped with a file system, and the unit of data can be handled as a file.

Next, details of securing the recording capacity in this apparatus will be described with reference to the flowchart of FIG. In this embodiment, when a program is reserved for recording or actually recorded, a retention time limit of a program to be recorded by the user is set, and when the time limit is reached, the device automatically deletes the program. It is a thing.

First, the general flow of the operation in this embodiment will be described with reference to the flow chart of FIG.
Step S1 is the starting point of the operation of recording a program, and the user specifies the program to be recorded. This can be specified by, for example, the user pressing a record button on the remote controller 10 or using a predetermined key on the remote controller 10 from an electronic program guide (hereinafter referred to as an EPG) displayed on the screen for recording reservation on the remote controller 10. The action such as selecting the program is applicable.

Next, if the recording button is pressed, the program currently being viewed is the program to be recorded in the HDD 6, and if it is the recording reservation, the program selected by the EPG is the program to be recorded in the HDD 6, respectively.
Information about the program and setting information about recording are displayed on the screen (step S2). The user confirms, among the information displayed in step S2, contents set in advance when the device is shipped, and then decides whether or not to change the holding condition of the file for recording the designated program (step S3). . If it needs to be changed, the holding condition is selected again (step S4).

When the above is determined, a file is created in the HDD 6 immediately when the recording button is pressed and when the program start time is reached when the recording is reserved, and the TS is recorded in the file from the decoder 3. Go (Step S
5). At the time of this recording, in order to manage the information of the recorded programs and files by the device and present it to the user in a list, in addition to the files of the TS recording, the program information and the file information are used as a management table in the HDD 6 or the nonvolatile memory. It is stored in the ROM 9 (step S6). Further, the setting value of the file holding condition set in step S3 or step S4 is also stored in this management table (step S6). This is the end of the recording operation.

After recording, the file holding conditions of the management table recorded in step S6 are acquired (step S6).
7) Then, the set value is constantly monitored to check whether it is within the set value of the holding condition (step S8). If the holding conditions are met, the process returns to step S7 again.
If the holding condition is not satisfied, the TS file recording the corresponding program is deleted (step S9). With regard to this step S9, automatic deletion processing may be executed at the discretion of the apparatus, or the result of the deletion may be notified to the user as a notice together with the program name. Alternatively, it may be possible to notify only that the holding condition has passed, and remind the user to confirm whether or not to delete by the screen display. When the file is deleted as described above, the automatic file deletion by the user's retention condition setting ends.

Next, referring to FIGS. 3 and 4, step S2
The screen display and operation in S3 and S4 will be described by taking a case of recording reservation as an example. Note that these figures are merely examples of screen images. When the program for which the recording reservation is desired is specified in step S1, a screen display for confirming the setting of the recording reservation appears as shown in FIG. Here, the program information 21 and the recording setting information 22 are displayed.
If it is not the program you are hoping for, click "Stop" 24,
If it is desired to change the recording setting information and make a reservation, "change setting" 25 is selected and set using the predetermined operation keys of the remote controller 10.

The selected item is displayed separately from other unselected items by changing the color. Further, the above-mentioned selection change and setting can be performed using a predetermined operation key (a dedicated cursor key, a decision key, etc.) provided on the remote controller 10.

In FIG. 3, "reservation date" 26 and "holding condition" 27 are displayed as recording setting information, but other settings such as "record subtitles" are also necessary. If the setting information is displayed. The setting values of all of these setting information are set at the time of shipment of the apparatus, and the "holding condition" 27, which is the most safe, is set not to be deleted as an initial setting value. However, in general, the purpose of recording is often clear before the program is recorded,
"I want to make a permanent preservation version" or "I need to see it only once"
There are also things such as, "I can't watch it at that time, so I don't know if I should watch it or not, but keep it for now." Therefore, when it is desired to change this, "Change setting" is selected, and the screen is displayed as shown in FIG.

Since a holding condition close to the purpose of recording is sufficient, the user is allowed to select one from the prepared values for the apparatus. In FIG. 4, “do not delete” 28,
"1 day" (deleted if held (elapsed)) 29, "1 week"
(Delete if held) 30, "1 month" (Delete if held) 31, "1 year" (Delete if held) 32, "Until play once" (Delete if held) 33, "Record same program" “(Delete when held) 34 is prepared as a set value.

The set value of the holding condition selected as described above is stored for each program recorded in the management table in step S6 and monitored in steps S7 and S8. Of course, the holding condition set here can be changed by the user thereafter.

Next, the table for managing the program and file information stored in step S6 is shown in FIG.
Will be explained. This table is used for the purpose of managing the recorded files in the device and for displaying the contents of the recorded program on the screen of the user. As shown in FIG. 5, the format is such that information about files, information about programs, and information such as setting values of holding conditions are collected in units of recorded programs and are sequentially connected.
The method of holding the set value relating to this holding condition is arbitrary for the device, and for example, "do not delete" 28 and "1 day" 2 in FIG.
9, "1 week" 30, "1 month" 31, "1 year" 32,
It is also possible to have a fixed numerical value such as 1, 2, 3, ..., 7 in order for "until played once" 33 and "until recording the same program" 34.

The management table stored as described above is referred to and constantly monitored to automatically delete files. For example, if the retention condition is set to "1 day", the current time and the "recording start date" in the management table will always be displayed.
The “recording start time” is compared, and when 24 hours have elapsed, it is determined that the file should be deleted, and the device automatically deletes the file. It is a matter of design whether to delete the file immediately or to notify the user only that the retention condition has passed.

According to the present embodiment, by ensuring the recording capacity according to the user setting information, it is possible to use the recording medium efficiently and reduce the risk of recording failure due to insufficient capacity.

Next, another embodiment of the video recording apparatus and the video recording method according to the present invention will be described. The block diagram of the apparatus is the same as that shown in FIG. In this embodiment, although the previous embodiment constantly checks the data concerning the record holding condition and deletes the broadcast program out of the record holding condition among the broadcast programs recorded in the recording means. On the other hand, for the already recorded program, the user has set to allow deletion when the capacity becomes insufficient, and if the capacity actually becomes insufficient during recording, the device deletes according to the setting information. The program is decided and the deletion is executed. Hereinafter, the operation will be described focusing on the points different from the previous embodiment.

FIG. 6 is a flow chart of this embodiment. It is judged that the capacity is insufficient during recording, whereas the previous embodiment always checks files and automatically deletes them while the apparatus is running. When it is done, the automatic deletion is executed for the first time.

When recording is started (for example, an operation in which the user presses a record button on the remote controller 10 or a recording reservation is executed at a designated time) corresponds to the HDD 6
A file is created for recording in (step S1
1) Then, the TS is recorded in the file (step S12). In step S13, it is detected whether or not the recording is completed. Therefore, the TS recording is continued until the user presses the stop button on the remote controller 10 or the program designated for recording is completed. HD
It is always checked whether or not there is still capacity in D7 (step S14), and it is judged whether or not there is a recording capacity (step S15). It should be noted that the determination of the presence or absence of the recording capacity is made such that it is determined that there is no empty recording capacity before the empty recording capacity is completely exhausted, in consideration of the time for securing the free recording capacity by file deletion described later.

When the lack of the recording capacity is recognized (NO in step S15), the set value of the "automatic deletion mode" preset by the user is acquired (step S16). Then, it is checked whether the "automatic deletion mode" is set (step S17), and if it is set, the file to be deleted is specified according to the setting condition (step S18). Then, it is checked whether there is a file to be deleted (step S19). Once the file is identified (step S
If YES in 19), the file is deleted (step S20). If the file can be deleted, it means that the capacity for the file size has been secured, and therefore TS recording is continued (step S12). When the user presses the stop button on the remote controller 10 or when the program for which recording is designated ends (YES in step S13), recording ends.

On the other hand, if it is determined in step S17 that the "automatic deletion mode" is not set, or that there is no file that can be deleted, the TS recording cannot be performed any more and recording is performed. Interrupt (step S2
1), it will end.

Next, the method of setting the "automatic deletion mode" obtained in step S16 will be described using an example of the screens shown in FIGS. "Automatic deletion mode"
Is set in advance by the user in the menu setting, and as described above, the automatic deletion is executed when the capacity is insufficient by looking at this set value.

"Automatic deletion mode" in menu settings
Although various setting methods can be designed according to the device, for example, by pressing a menu button (not shown) of the remote controller 10 to display a "menu" screen as shown in FIG. It suffices to let the user perform the setting in "3-1. Automatic deletion mode setting" 42 included in ". HDD recording setting" 41. When "3-1. Automatic deletion mode setting" 42 of this menu is selected by the selection key of the remote controller 10 (for example, the above-mentioned item in the menu is selected by the cursor key and the selection key is determined by the decision key), as shown in FIG. The "Automatic deletion mode setting" screen is displayed, and "Do not set" 43, "Set" 44, and "Change setting contents" 45 can be selected on this screen.

When setting the "automatic deletion mode",
It is also possible to set a condition for specifying a file to be deleted by automatic deletion, and the condition that has already been set or the factory default initial setting condition is displayed on the screen as "automatic deletion setting content" 46. The user sets “set” 44 when the setting content is acceptable, “changes the setting content” 45 when the user wants to change the setting, and “does not set” 43 when the automatic deletion is not performed. select.
As the "automatic deletion setting contents" 46, for example, "recording information" 47, 1 for preferentially deleting oldest recorded ones, etc.
There is information about "unreproduced" 48 such as deleting only those that have been reproduced once, information about "genre" 49 that deletes only applicable genres such as dramas, and "change settings" 4
When 5 is selected, the user sequentially sets these deletion conditions.

The deletion condition for the "recorded information" 47 is "not specified" 51 in the screen display as shown in FIG.
A selection is made from "from oldest recorded image" 52, "from newest recorded image" 53, "from large recording amount" 54, and "from small recording amount" 55. In addition, the deletion condition regarding the information of "unreproduced" 48 is as shown in FIG.
In the screen display as shown in, "No designation" 56,
A selection is made from "from once reproduced" 57 and "from never reproduced" 58. Also, "genre"
The deletion condition regarding the information of 49 is "No designation" 59, "Movie" 60, in the screen display as shown in FIG.
"Sports" 61, "Music" 62, "News" 63,
Selection is made from major categories such as “drama” 64 and “animation” 65. Even if these deletion conditions are set, it is of course possible to individually lock a recorded program which is difficult to be deleted by another user interface to prohibit deletion.

The user sets the "automatic deletion mode" by the above-mentioned procedure, and if the capacity is insufficient during recording, the file to be deleted is specified and deleted from this set value. It will be. “Recorded information” 4
When conditions are set for each of the three types of information, 7, "unreproduced" 48, and "genre" 49, files to be deleted are those that satisfy all of the above setting conditions.

According to the above-described embodiment, when it is determined that the recording capacity is insufficient during recording, the apparatus determines the program to be deleted according to the setting information and executes the deletion, so that the recording capacity shortage is resolved. This has the effect of reducing the risk of recording failure. Further, since a plurality of conditions can be set as the deletion condition, it is possible to perform file deletion (record deletion) more in accordance with the user's wish.

The present invention is not limited to the above embodiments. For example, in various settings such as the record holding condition, the set value at the time of shipment from the device is adopted unless the setting is changed, but the set value can be changed according to the user's preference. . For example, it is possible to store the last selected item so that the item is selected and displayed first at the time of the next setting, or a specific item is always selected and displayed. Besides, various modifications can be made without departing from the gist of the present invention.

[0045]

As described above, according to the present invention, the recording capacity is secured according to the user's setting information, so that the recording medium can be used efficiently, and the recording failure may occur due to insufficient capacity. A video recording device and a video recording method that can reduce the number of video recording devices can be provided, which is useful.
