Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a program recording / reproducing method, a program recording / reproducing apparatus, and a program recording / reproducing program for reserving and recording a program to be broadcast on a randomly accessible recording medium such as a hard disk recorder. .

[0002]

2. Description of the Related Art Conventionally, VTRs, hard disk recorders, etc. have been equipped with a program reservation recording function for recording a program to be broadcast at a set recording time. Is reserved and recorded, and is used as a time shift machine for viewing when the user's viewing time can be secured.

A video signal recording / reproducing apparatus using a randomly accessible information signal recording medium such as a hard disk as a recording medium can record a plurality of video signals simultaneously because the access time for recording and reproducing is short.
Further, it has a function of being able to record and reproduce the video signal at the same time.

Further, a video signal recording / reproducing apparatus having the simultaneous recording / reproducing function reproduces a video signal, which has started recording in the past, so as to catch up with a video signal being currently recorded, and a chasing reproduction and a program being broadcast. It has a convenient function such as cache playback that allows you to watch while continuously shifting the time from the present to the past.

The conventional cache recording / playback function has been used as an auxiliary function relating to program viewing, such as recording while viewing a program and playing back the missed program portion again for viewing. If the recording / reproducing function can be used as a more convenient recording / reproducing function, viewing / listening of a video signal becomes more preferable.

The cache recording / reproducing function for constructing the preferable viewing environment is different from the program recording function in the so-called VTR, which is different from the program recording reservation in which the start time and the end time are explicitly designated. Even if you do not make a recording reservation for such a program, the program broadcast on the set broadcasting channel is recorded for a certain period of time, and you can watch the recorded program retroactively from the present to the past as necessary. Is something that can be done.

The cache recording / reproducing function, for example, designates a program to be re-received by using the electronic program guide information acquired in advance, so that the designated program can be reserved for recording by a simple operation. It can be used as a recording device for viewing while watching.

Further, in the case of a normal recording device such as a VTR, it is impossible to record a program exceeding the recording capacity of the recording medium to be set, and it is necessary to delete the program recorded by the recording reservation sometime. Although there is a method of automatically deleting the deletions in order from the oldest program, such automatic deletion is not necessarily a deletion processing method preferable for the user.

Further, in the usual case, since the reproduction of the recorded program is completed on a program-by-program basis, it is possible to record three programs continuously or discontinuously on the time axis. In this case, it is not possible to skip the second program from the first program and skip the third program as a continuous program while using the search function.

On the other hand, in the case of cache recording / playback,
When a program is recorded in a preset recording area and the program is recorded beyond the recording area, the oldest program is
The program is automatically erased, and the recorded programs from the latest recording position to the oldest recording position in the current cache recording can be watched regardless of the type of the program.

[0011]

By the way, the cache recording / reproducing function is a convenient function as described above. However, the cache recording / reproducing function which has been conventionally realized is such that the receiving channel is changed during the cache recording. In this case, the recorded contents relating to the reception channel before the change recorded in the cache are erased, and the record signal recorded before the time when the reception channel is changed cannot be reproduced.

This is because noise occurs in the video signal received when the receiving channel is changed, for example, in the period until the TV tuner is switched and the signal is synchronized with the broadcast signal of the receiving channel, and when the channel is switched during normal TV viewing. The noise component that is generated takes measures for viewing by muting processing such as turning off the video signal, and the viewer also operates the muting processing when switching channels by the viewer's own operation. This is a phenomenon caused by doing so and I do not feel a big discomfort.

However, when the noise signal generated by the channel switching operation in the past or the muted video signal is viewed by the cache reproduction function, it occurs in the past which is not based on the current operation of the viewer. The discontinuous signal causes an uncomfortable feeling, which is unfavorable. In order to prevent the uncomfortable feeling, the cache recording / reproduction exceeding the changed portion of the receiving channel is prohibited.

Regarding the processing of the noise signal generated at the time of changing the reception channel, Japanese Patent Application No. 2001-219421 filed by the present inventor and filed by the present applicant.
No. “Video signal recording / reproducing method and video signal recording / reproducing apparatus” (unpublished at the time of filing of the present application), the cache recording / reproduction has a more convenient function for the user when used together with the solution. The cache recording / playback function can be realized.

In the cache recording / playback thus realized, cache recording reservation can be made by designating time information to be recorded and an input source such as a broadcast channel. The cache recording reservation may be made by designating a recording start time, an end time, a broadcast channel, and the like similarly to the recording reservation in the conventional VTR, and further, using the electronic program guide, the program guide The recorded program may be selected by performing the recording reservation operation on the display screen of.

Therefore, in order to make the cache recording / playback, which is a convenient function for the user, a more convenient function, the present invention automatically caches it by designating a plurality of programs that are discontinuous in time. Allows you to record,
Enables cache recording / playback even when programs to be cache-recorded are broadcast continuously over time, or when they are not continuously broadcast, and even when broadcast on different channels. Even if the broadcast times of the programs to be played are designated in duplicate, the conditions for the suitable cache recording / playback are selected.

Further, according to the present invention, in order to improve the cache recording / reproducing function, in the conventional cache, the cache reproduction is stopped when the reserved time for the normal recording arrives while watching the program recorded backward in the past. The normal recording program was displayed, and the program that was being watched was deleted. However, the cache recording / playback method improved even for such an operation that the user does not want. Is also disclosed.

Is read out in response to a request from the -2 decoder 72 and supplied to the MPEG-2 decoder 72.

In the MPEG-2 decoder 72, the supplied compression-encoded video signal is decoded by the encoder 53 based on the MPEG-2 standard, and the decoded digital video signal is OSD 73. Is supplied to the D / A converter 74 via the digital video signal, where the digital video signal is converted into an analog video signal and the monitor TV 90 is connected.
Supplied to and displayed.

In the OSD 73, a display signal to be displayed by being multiplexed with a video signal displayed on the monitor TV 90 is generated as needed, and the generated display signal is directly displayed on the monitor TV 90 or is decoded. An analog signal supplied to the D / A converter 74 and supplied to the monitor TV 90 is generated as a digital video signal to be displayed as a composite signal multiplexed with the generated video signal. A video signal is obtained.

As described above, in the program recording / reproducing apparatus capable of recording / reproducing at high speed in the cache area of the hard disk divided by the sector size, the data is recorded at distant positions in the cache area. A program can be continuously reproduced, and a program that has been cache-recorded in the past can be reproduced while cache-recording a program that is currently being broadcast.

Next, cache recording / reproduction for recording / reproducing such a program will be further described. The signal for the cache recording is a coded bit stream obtained by being coded by the MPEG-2 encoder 53, and a predetermined part of the recorded program is searched for and reproduced, or the beginning of the program is searched for. Information for GOP is obtained from the signal encoded by the MPEG2 encoder 53 for reproduction and reproduction, a management table is generated by the management table generator 57 based on the obtained GOP information, and the generated management is performed. The table is recorded on the hard disk 63.

FIG. 2 shows the relationship between the management table and the stream area for recording the encoded stream. In the same figure, the relationship between 25 stream area portions each having a vertical and horizontal length of 5, and 25 management table portions provided corresponding to the respective area portions is shown.

.., 24, 25, 1, 2, 3, ...
The encoded bitstreams are recorded in the order of ... And the GOP information and the like relating to each of the stream area portions are recorded in the corresponding management table portion.

In this way, the coded data is cyclically recorded in the 25 stream area parts, and the recorded old coded data is sequentially overwritten by the new coded data. The GOP information and the like are also overwritten.

In the example shown here, the management table has 25 entries for each management table section, and the 26th section overwrites the first recorded area section. Capacity is 1
In the actual cache recording area which is time, in the case of recording encoded data in GOP units in the stream area part,
Since the time interval of a normal GOP is about 0.5 seconds, the number of entries in the table is about 7,200. However, the number of entries in the table and the setting method of the cache recording time are design items, and future Since the price of large-capacity hard disks is decreasing, the cache recording time tends to be long, such as 8 hours and 12 hours.

As described above, in the conventional program reservation recording, recording for the purpose of storage in a predetermined recording medium is made.
It was used so that the recorded contents were saved until a new program was overwritten and recorded.However, like the cache recording / playback described here, the cache recording area is set in advance in the recording medium and the cache area is set. With the usage method of recording and playing broadcast programs, many programs can be recorded and viewed easily, such as recording a program with a cache reservation and watching it once, or watching only the necessary part. It is a thing.

In the cache recording which is carried out easily, the electronic program guide is obtained from the electronic program guide provider via the network, or the electronic program guide information is obtained from the auxiliary received signal, and the obtained electronic program guide is obtained. Is displayed on the monitor TV 90 by the OSD 73, and the name of the program to be reserved for recording is selected by operating the arrow keys and the enter key of the remote controller 95, or a plurality of reserved program names are selected, and the broadcast date is selected from the selected program information. Get information such as start time and end time,
A program signal received by a broadcast channel broadcast based on the obtained information or a tuner unit connected to an external input terminal is obtained, and the obtained program signal is recorded in a cache area. .

In this way, the encoded signal recorded in the arbitrary stream area portion is cache-recorded by designating and reading the arbitrary area portion of the recorded signal based on the management information recorded in the management table. It is possible to realize recording / reproduction of a video signal in which an arbitrary part of the video signal can be selected and reproduced.

Then, even if the electronic program guide information cannot be obtained, the cache reservation recording thus realized is announced, for example, by the information of the weekly magazine that publishes the TV program guide or from the television station. It is also possible to make a similar cache recording reservation by designating a program to be cache-recorded by a G code or a remote control key operation based on the program advance notice information.

In this manner, the so-called cache recording / reproducing function is a function of recording the program being viewed and easily viewing the past program portion when there is missed information or program information to be repeatedly viewed. However, the cache recording reservation function is an addition of the program recording reservation function.

In the program recording by the cache recording reservation thus made, a plurality of programs can be reserved and recorded, but if the plurality of programs are not continuously broadcast, the recording is intermittent. The cache recording reservation that is performed in this way will be described next.

FIG. 3 shows a display example in which a plurality of programs are reserved for cache recording on the electronic program guide. In the figure, the horizontal direction indicates the broadcaster, the vertical direction indicates the time, and the program enclosed by the red line (indicated by the thick line in this figure) is the program for which the cache recording is reserved.

That is, the programs reserved for cache recording are "program A" broadcasted by the broadcaster A from 17:50 to 18:00, and from 18:00 to 19:00.
The “program B” is broadcast by the broadcaster B until 0 minutes, and the “program C” is broadcast by the broadcaster A from 19:40 to 19:45.

In the case of normal cache recording, the program being viewed is always recorded, but in the case of cache reservation recording described here, when recording of a program is reserved intermittently. , The period from 18:00 to 18:30, which is not the target of other scheduled recording,
Also, the period from 19:00 to 19:40 is a pause period for cache recording, and cache recording is paused in these sections.

In this way, since the cache recording is suspended, the programs broadcast during those periods cannot be cache-reproduced, but the programs recorded in other periods and the cache recording are reserved. The recorded and recorded program can be reproduced.

By describing the identification mark in the management information of the recording start portion of the cache recording portion thus intermittently performed, the user can easily perform the cue reproduction operation of the cache recording reserved program.

When the cache recordable area for the cache recording time is not large enough, the program recorded first is reserved by recording by stopping the cache recording after recording the last cache reserved program. It is possible to prevent the operation of overwriting and recording a new program.

In this way, the cache recording before the first reserved program is cache-recorded is operated, but whether the non-reserved program is cache-recorded after the cache reserved recording is started or is temporarily stopped. Setting is free and it is also a design matter, but in the example described here, if there is an unrecorded cache reserved program after the recording of the reserved program is started, the cache recording of the unreserved program during that period is not possible. I try not to do it.

The design of the cache operation after the recording of all the reserved programs is finished is also a design matter. However, if the cache recording area is not large, the subsequent cache recording is stopped. In this way, the normal continuous cache recording is performed after the cache recording reserved program is viewed.

In this way, in the cache recording reservation when the cache recording area is not set for a long time, the reserved and recorded program is cached so that other programs are not overwritten and recorded with the passage of time. Although the recording operation is limited, if the cache recording area is secured for a long time of, for example, about 12 hours, the cache recording is continued without pausing the cache recording.

That is, the recording is started at 17:50 and the recording by the cache reservation is finished at 18:00, but the recording of the program broadcast from the broadcaster A is continued thereafter, and the recording is started at 18:30. Broadcaster B immediately before receiving channel
Change to, and the cache recording of "Program B" is started.

Then, even after the end of recording of "Program B" at 19:00, "Professional baseball" started at 19:00 is continuously cache-recorded, and the reception channel is set to the broadcaster A immediately before 19:40. Change to and record "program C" in cache.

In this cache recording method, the reception channel is changed to a channel for newly reserved recording just before the start of a new cache-reserved program, but when a program broadcast on the same channel is reserved for recording, it is changed to that channel. The received program is continuously cache-recorded.

In such an operation, the recording reservation is designated by reserving the timing when the receiving channel is changed, but the cache area can be set to a large capacity.
For example, when the time that can be cache-recorded without overwriting is 8 hours or 12 hours, the above configuration is used, and in such a configuration, the programs recorded in the cache area are temporally consecutive. Therefore, when the program recorded by the user is viewed retrospectively, it is easy to obtain a feeling of the time when the broadcast program was actually recorded.

As described above, the broadcast program is recorded on the basis of the cache reservation setting. For example, the current time is 19:30, and the reserved recording of "program A" or "program B" is performed. However, the program recording / playback apparatus described in this example can perform the cue playback of those programs reserved for recording by a simple operation.

In the cue reproduction of the cache recording reserved program, the recording start position information of the program is stored in the management table 57 described above during the cache recording, and the stored management table information is recorded in the hard disk 63. Since the recorded management table information is read out and temporarily stored in the management table 75, the recording position desired to be viewed is read out by the key operation of the remote controller 95 or the like, and the reproduction position of the hard disk is controlled by the controller 65. By reproducing, the target program can be easily found and reproduced.

Then, the designation of the program for the cue reproduction is reserved and cache-recorded by operating the arrow key and the decision key of the remote controller for the thick frame reserved for cache on the electronic program guide. A desired program may be selected and the start position of the program may be searched for and reproduced.

Further, when the cache recording of the program designated for the cue reproduction is not started yet, the program cannot be reproduced, but the cache-recorded program has already been overwritten with another program. However, when the program is overwritten, it is not possible to reproduce the cueed program.

The reproduction of the program which has been erased by such overwrite recording of the first portion is started from the oldest recording area of the recording portion which has not been erased yet.

Further, when all of the designated programs have been overwritten and recorded, the programs can no longer be reproduced. Therefore, for programs that can be played back only from the middle and programs that cannot be played back, the identification display such as the red frame (thick frame) displayed on the electronic program guide is deleted, or the display color inside the frame is changed. The viewer is identified as a program that cannot be played back.

In this way, the cache recording reservation is made on the electronic program guide, and the recorded program is recorded in the cache area, the program erased by the partial overwrite recording, the program erased all, etc. By displaying such information by changing the line thickness on the electronic program guide, changing the type of line such as a solid line or a dotted line, changing the color of the line, or changing the display color inside the frame, the user can Makes it possible to obtain the identification information related to the recording state of the program reserved for cache recording.

As a practical application example relating to the designation of the recording reservation on the electronic program guide and the state identification of the recorded program, for example, the program desired to be cache-recorded in the evening busy time is displayed on the electronic program guide. Only some designated programs are recorded in the cache area, and the cache recording is stopped as it is after the last designated program is recorded.

Then, at midnight, the electronic program guide is displayed when the viewing time is obtained such as when the child goes to bed, and the program desired to be reproduced is selected from the cache-recorded program information. For example, today is late so don't watch the first show
After the viewing is started from the second time, and after the viewing of the program part for the viewing purpose of the user after the viewing is started, the cue reproduction of the next cache-recorded program is performed by operating the remote controller keys.

Then, in order to reproduce the next cache recording reserved program, the "next cache recorded program cue reproduction" button provided on the remote controller 95 is operated without displaying the electronic program guide on the monitor TV. Therefore, the microcomputer 76 is adapted to perform the cue reproduction of the program displayed on the electronic program guide for recording identification display.

In this way, the reproduction of the program recorded by the next automatic cache recording reservation is automatically performed.
By easily designating a predetermined recording address position of the hard disk 63 on the basis of the information on the recording start position of the program information recorded in the cache area recorded in the management table 75, the cue and reproduction can be easily performed. Is.

The automatic cue reproduction of the program recorded in the cache by making the cache recording reservation on the electronic program guide has been described above. Next, the designation of the cache recording reservation performed on the electronic program guide will be further described. FIG. 4 shows a case where the broadcast times of the cache reserved recording programs are designated in an overlapping manner.

In the figure, from 11:25 to 13:00
Program "Program G" that is broadcast by Broadcaster C until 0 minutes,
The program "program F", which is to be broadcast by the broadcaster B from 12:00, is reserved for cache recording.

The reason why the recording reservation is made in the overlapping time is that the recording reservation can be set for each program, and the hard disk 63 of the program recording / reproducing apparatus 40 has the high-speed random access function. Although it is possible to record two programs by utilizing the above, the program recording / reproducing apparatus 40 has only one recording unit 50 for economic reasons, and therefore two programs to be broadcast are recorded simultaneously. You cannot do it.

Therefore, when two systems of programs overlapping in time are reserved for recording, it is necessary to select and record one of the programs, which is selected at 12:00.
There is a selection such that the reception channel is recorded according to the broadcaster B from 0 minute, or the program of the broadcaster B is recorded from 13:00. Temporary setting is made in advance by performing either method.

The contents of the temporary setting can be changed by the user as necessary, or the user may select any one of the methods at the time of setting the reservation of those programs. The set reservation status is displayed on the program guide so that the user can recognize it.

In FIG. 5, cache recording reservation is set,
A display example in the case where a portion to be recorded is displayed with a thick frame is shown. In the same figure, it is shown that the programs of the broadcaster C that have been initially set to be reserved for recording are all finished and that the programs broadcast from the broadcaster B after 13:00 are reserved for recording. ing.

In FIG. 6, cache recording reservation is set,
A display example in another case where a portion to be recorded is displayed with a thick frame is shown. In the figure, the receiving channel is switched to the broadcaster B at the time when the program of the broadcaster C that is initially set for recording reservation and received is not finished, and the program to be broadcast from 12:00 is reserved for recording. Is shown.

As described above, as to which of the programs having the same broadcast time to be selected and recorded, for example, the "reservation mode switching" icon is operated by operating the arrow keys and the decision button of the remote controller 95 or the like. The reservation mode may be set and the recording reservation may be made later.

There is also a method of recording the program reserved for duplication by recording the other program on the way and then returning to the program of the channel before switching again.
FIG. 7 shows a display screen of a recording reserved program in which a recording reservation of another program is set within the recording reserved time.

In the figure, from 11:25 to 13:00
11:03 between programs broadcast by Broadcaster C until 0 minutes
This shows a state in which the program to be broadcast by the broadcaster D is reserved for recording from 0 to 12:00.

It is considered preferable for the user not to make such a recording reservation that another program is inserted between one program, but for such recording reservation setting. It is a matter of design whether to issue a warning and schedule recording of a single program, or to record two programs according to a method set by the user.

FIG. 8 shows a state where the broadcasters A and B have reserved the programs to be broadcast at the same time. In the figure, programs of broadcasters A and B to be broadcast from 18:00 to 18:30 are reserved. With regard to such program reservation, at present, one of the programs is selected and recorded as described above.

The method of recording a broadcast program by making a recording reservation in the cache recording / reproducing function has been described above. In the program recording / playback device equipped with the cache recording / playback function that has been used as a product, the specifications of the cache-recorded program are extremely easy to erase, such as deleting the contents of the cache-recorded program when the receiving channel is changed. Although there were many cases, the function of recording while changing the receiving channel as described above and viewing the recorded program at the user's desired time is realized as a suitable recording function for a new broadcast program.

The cache recording reservation function is
The conventional program also has a function of recording a program in a program storage recording area different from the cache area. Next, those recording functions will be further described.

The recording for the purpose of storing the program and the cache recording for temporarily recording the program have different priorities for recording, and the recording for storing the program is prioritized. That is, when the normal recording is started during the cache recording, the cache recording is stopped and the normal recording is stopped in both the case where the recording is manually operated and the case where the recording is started by the recording reservation. Recording starts.

[0100] Such an operation in which normal recording has priority takes priority over normal recording in the case of a recording / reproducing apparatus equipped with only one expensive MPEG-2 encoder for performing normal recording. Although the cache recording is stopped in that case as well, in the past, such recorded contents that were in the middle were erased without watching, but in the cache recording described in this example, The contents of the cache, which is a record, are not erased, and although the contents of the cache that have been recorded are halfway recorded, the video signal of the recorded portion can be reproduced.

In such an operation, for example, while watching a program having a time difference by the cache recording / reproducing function, the program content is suddenly changed to the program to be reserved for recording,
Even if the replayed video of the recorded program is displayed, the cached recording contents recorded up to that point are not deleted, and the cached program of the time difference can be viewed as it is. It can be said that this is the more preferable reproduction method for the viewer.

As described above, there have been many examples of products in which the contents of the program recorded in the cache are erased when the receiving channel is changed. However, in the program recording / reproducing apparatus shown in this embodiment, recording is performed. Of the recording area of the hard disk to be recorded, video and audio signals can be recorded up to a specified time length or a predetermined time length determined by the ratio to the free space of the medium,
A recording / reproducing method using a recording area of a medium as a recursive buffer, in which video and audio signals exceeding the upper limit are overwritten in order from the oldest signal so that the area in which the oldest signal is recorded is erased. , The recording in the cyclic buffer is already recorded without erasing the recorded contents of the cyclic buffer even if the recording cannot be continued due to another type of recording process that is prioritized. As for the contents, it is possible to freely play back the recorded part even during the recording process of another different form, and to continue recording at the position of the area where the previous recording was stopped again, and to record the recorded part as it was done conventionally. The present invention realizes a recording / reproducing method capable of resuming recording in the cyclic buffer without erasing all the data.

As described above, program recording for so-called storage,
The method of program recording / playback that has a cache recording / playback function for recording video signals in a cyclic buffer has been described. In the program recording / reproducing apparatus configured to prevent the programs recorded in the cache from being erased as much as possible, unlike the conventional case, it is convenient if the programs recorded in the cyclic buffer (cache memory) can be easily reproduced at the beginning. Is improved.

Next, a method for facilitating the cue reproduction of a program recorded in such a cache memory will be described. FIG. 9 shows a display example of a search screen for performing a cue reproduction of a cache-recorded program signal.

In the figure, the content (program) names recorded in the cache memory are obtained from the electronic program guide and displayed in the form of a list on the video screen being reproduced. Of the displayed program names, Remote control the desired program 95
When a new program is overwritten from the beginning of the program or the first recording area of the program by operating the key of, the program from the oldest recording area position that can be played at present is selected. I'm trying to play.

That is, here, three programs can be selected, and the title names of those programs are displayed. The numbers shown on the left side of the program names are serial numbers, and the numeric keys 1 to 9 of the remote controller. The program can be selected and reproduced by the, but it is a design matter whether the reproduction is designated by the numeric keys or is selected by using the arrow keys and the decision key of the remote controller.

The title name of the program can be obtained from the electronic program guide, but in a device that cannot display the title name based on the description data of the electronic program guide, the broadcast channel and the recording time information are displayed. Alternatively, a method of performing access reproduction by designating a recorded program from the display information may be used.

Furthermore, whether the recording status of the cache-recorded program is currently being recorded or has been recorded,
Or, information on whether or not another program is erased by overwriting recording or the like is displayed in the recorded first portion by, for example, changing the display color of the program name or changing the icon.

Further, by displaying the programs for which the recording is not started but the cache is reserved by the same list, the user can easily grasp the state of the cache recording reservation,
It may be performed in combination with the above display, and in this way, a convenient cache recording / playback function for the user can be realized.

In the figure shown here, the list of recorded program names is displayed by being multiplexed with the video signal being reproduced, but the recorded program list is displayed directly instead of being multiplexed with the video signal. You may do it.

The configuration and operation of the program recording / reproducing apparatus equipped with the cache recording / reproducing function for performing the cache recording reservation based on the electronic program guide and reproducing the recorded program signal have been described above. And, those operations are performed by the microcomputer 7.
There are many operations performed under the control of a computer program stored in 6.

Next, the operation executed by the computer program will be further described. FIG. 10 is a flowchart showing a flow of operations relating to cache recording reservation, cache recording, and updating of an identification electronic program guide created for cache recording.

In the figure, first, it is necessary to acquire an electronic program guide for easily making a cache recording reservation. However, in S11, the EPG decoder 5 in FIG.
In step 6, it is determined whether or not the electronic program guide information has been acquired, and when the electronic program guide information has not been acquired, the electronic program guide provider via the Internet determines in step S12.
Or an electronic program guide that is multiplexed with the broadcast wave being received
Obtained from the tuner 51.

Next, the acquired electronic program guide information is stored in the temporary storage memory 78 connected to the microcomputer 76 in S13, and in S14, a plurality of recording reserved programs are set as shown in FIG. To do.

The recording-reserved programs thus set are S1.
5, the identified electronic program guide is displayed by identifying the recorded program of the electronic program guide stored in the temporary storage memory 78 by enclosing it with a red frame, for example.

The program information to be identified and displayed is managed by the microcomputer 76. When it is determined in S16 that the broadcast start time approaches, the microcomputer 76 changes the reception channel of the TV tuner 51 in S17.
Alternatively, the video signal supplied from the external input terminal is supplied to the A / D converter 52 depending on the program received by switching to the video signal supplied from the external input terminal or the program for recording.

Although not shown, when a video signal to be recorded is supplied as a digital signal from an external input terminal, the supplied signal is directly supplied to the MPEG-2 encoder 53.
Supply to. The video signal thus supplied is MP
The encoded signal is compression-encoded by the EG-2 encoder, and the encoded signal is recorded in a predetermined cache area of the hard disk 63 in S18.
In step 19, the start of recording of the program of interest in the identification electronic program guide is updated by, for example, changing the color of the identification display.

Although the recording of the program is continued in this way, it is checked in S20 whether there is a program to be newly overwritten and erased, and when the overwriting recording to a new program is started, By S21, the electronic program guide for the program recorded in the past, which has been erased by overwriting recording, is updated, and the operations of S20 and S21 are continued until the end of recording is detected in S22.

Next, when the recording end of the recording reserved program is detected in S22, the identification program table to be displayed as the recorded program name of the recording reserved program is updated in S23.

Then, in S24, it is detected whether or not recording of all the recording reserved programs has been completed, and if not completed, the recording start time is detected in S16, and the same steps are performed. , S24, when the recording end of all recording reserved programs is detected, the recording operation related to the recording reservation is ended.

The programs recorded in this way are displayed in a list for the cue reproduction. Next, the flow of operation for that purpose will be described. FIG. 11 is a flowchart showing the operation for generating the identified program list from the identified electronic program guide information.

In the figure, first, the identification electronic program guide is obtained in S31, the identification program name described in the identification electronic program guide is obtained in S32, and the obtained identification program guide information is obtained in S33. Then, an identification program list is created.

Then, by S34, S19, S21,
Alternatively, it is detected in S23 or the like whether or not the identification electronic program guide is updated, and if detected, the identification program list is updated in S35 based on the updated identification electronic program guide information.

Then, in S36, it is detected whether or not the recording of all the reserved programs in S24 is completed, the information of the detected recording end is obtained, and the operation of updating the identified program list is completed. Although not shown, when a new recording reservation for cache recording is made, an identification program list for displaying the program names reserved for recording in the identification program list information is also created.

The identification program list thus created is supplied to the OSD 73 when an operation for displaying the list is made by the remote controller 95 or the like, and supplied from the MPEG-2 decoder. It is multiplexed with the displayed video signal or its identification program list is displayed alone.

The part of the computer program for executing the microcomputer 76 incorporated in the program recording / reproducing apparatus has been described above. In addition to the above-described cache recording / playback function, the program recording / playback apparatus also has a function of changing the input source at a predetermined time, pausing cache recording, or stopping cache recording. Have

The predetermined time is the time at which the reservation of the cache recording is executed, and the time is the same as the recording reservation by the designation of the program on the electronic program guide or the time designation used in the conventional VTR. Is done.

When the received broadcast program is a compressed coded signal coded by the MPEG-2 system, the coded signal is directly supplied to the stream analyzer 54 for recording. It also includes a change of the input source in the case where a digital video signal is supplied without going through the TV tuner 51.

Further, the recording medium used in the medium section has been described focusing on the hard disk, but the recording medium is a medium that can be accessed at high speed, such as a magneto-optical disk or a RAM.
It is also applicable to an apparatus using another recording medium such as a DVD type or RW type DVD and a semiconductor memory type recording medium.

It has been described that the recording area for performing the cache recording / reproducing defines a predetermined amount of recording area in the recording medium, and cyclically records and erases in the defined recording area.

That is, according to the method, the information signal including the supplied video signal is recorded in the end area portion of the recording area in which the predetermined amount of time-series signal can be recorded, and When the recording reaches the end area portion, the next recording is performed from the first area portion so that the information signal is cyclically recorded in the recording area and is recorded in the recording area. A recording / reproducing method of a program for performing a cache recording / reproducing in which the recorded video signal is reproduced by designating and reading an arbitrary area portion, and a program is scheduled to be broadcast in a plurality of programs to be broadcast. A first step of obtaining the electronic program guide information, and a second step of attaching a related identification mark to a plurality of program names to be reserved for recording among a plurality of program names described in the electronic program guide information. And a third step of obtaining the video signal relating to a received signal received by broadcasting the program with the identification mark, and recording the information signal including the obtained video signal in the recording area. And a plurality of programs recorded in the recording area, or programs being recorded,
A fourth step of selecting an arbitrary program from among the above and reproducing the selected program to obtain the video signal.

On the other hand, for the predetermined recording area for performing the cache recording, the distribution ratio between the area for recording the program signal for storage on the recording medium and the area for performing the cache recording is set, and the distribution is performed. The ratio depends on the size of the free area on the recording medium, for example, when the free area is large, the cache area is set to a large ratio to perform cache recording / playback, depending on the size of the free area where the information signal can be recorded. The cache area can be set to increase or decrease.

Further, the set recording area for the cache recording / reproducing is performed by setting a cluster number or the like as an area fixed in the recording medium, and also by setting a predetermined ratio to the recording medium. There is a method of performing cache recording / playback while moving the cache recording area while maintaining the ratio thus set.

The cache recording performed while moving the cache recording area has, for example, 10,000 free clusters on the hard disk from number 1 to 10000.
This is a case where the cache recording area is set to 1/10 and 1000 cache recording areas are secured.

The cache recording of the information signal is started in the areas having the cluster numbers 1 to 1000 set in this way, and the next recording of all the information signals is recorded as the cluster number 1001.
Recording is performed over 1000 areas such as 1002, ..., And the already recorded cluster numbers 1, 2, ...
It is a cache record that is erased in the order of.

In the case of such recording, the area secured as the cache area is 1/10 of the entire recording medium.
While the cache recording area is moved, the cache recording and the reproduction thereof are performed cyclically and continuously while the cache recording area is moved.

As described in detail above, by using the cache recording / reproducing function of recording and viewing a program simply, such as cyclic recording on a recording medium, the name of the recorded program is changed to an electronic program. The cache recording reservation made using the program names described in the table can realize a new program viewing environment, such as enabling time-shifted program viewing with a simpler operation than before. It is possible.

[0138]

According to the first aspect of the invention, a program recording / reproducing function is provided which has a cache recording / reproducing function of cyclically recording in a recording area of a predetermined recording capacity and reproducing a signal of an arbitrary recorded area portion. In the method, the electronic program guide information is acquired, and a desired program of the electronic program guide is reserved for recording and recorded in a recording area, and any recorded program is selected and reproduced. Provides a program recording / playback method that allows cache reservation recording even when programs to be cache-recorded are continuously broadcast in time, or not continuously, and even when broadcast on different channels There is an effect that can be done.
