As a result, the TS signal of the broadcast program recorded on the optical disk 18 is read and reproduced, and the image and sound can be viewed through the monitor receiver (television receiver) or the like. It

For example, an external IRD (Integrated
When recording a digital signal input from a receiver decoder via a digital interface such as IEEE 1394, the digital signal is input to the digital interface circuit 3 through the digital input / output terminal 2.

Although the connection with the IRD has been described here, AV (audio / visual) equipment such as TV,
It is also possible to connect the personal computer and the recording / reproducing apparatus of this embodiment shown in FIG.

Further, in the recording / reproducing apparatus of this embodiment shown in FIG. 1, the digital BS / CS tuner 1 is also connected to the multiplexing / demultiplexing circuit 16. This digital BS /
The CS tuner can output the TS signal to the multiplexing / demultiplexing circuit 16. The operation of each circuit portion after the multiplexer / demultiplexer circuit 16 in this case is as described above.

[Detection of CM Section and Recording on Optical Disc] Next, the CM section detection processing performed in the recording / reproducing apparatus of this embodiment shown in FIG.
Recording of information indicating the section on the optical disc will be described in detail.

FIG. 2 is a block diagram showing a part of the recording / reproducing apparatus shown in FIG. 1 in more detail. Mainly, the pre-audio signal processing circuit 9, the pre-video signal processing circuit 14 and the MPE are shown.
The G audio / video decoder 19, post audio signal processing circuit 20, and post video signal processing circuit 23 are shown.

Audio data is input from the audio A / D converter 8 to the pre-audio signal processing circuit block 9. The pre-voice signal processing circuit block 9 includes a signal processing circuit 31 and a silence detecting circuit 32. In the signal processing circuit 31,
The input voice data is filtered to remove noise.

The silence detecting circuit 32 detects a low level portion of the audio data. The position information of the detected silent portion is stored in the RAM 30 by the system controller 28. The audio data is compressed by the MPEG audio encoder 10 and transferred to the multiplexing / demultiplexing circuit 16.

On the other hand, the pre-video signal processing circuit block 14
The image data is input from the NTSC decoder 13. The pre-video signal processing circuit block 14 includes a field memory 33, a scene change detection circuit 34, and another signal processing circuit 35.

The scene change detection circuit 34 detects a scene change point at which a scene changes by using, for example, a field difference. The position information of the detected scene change point is stored in the RAM 30 by the system controller 28. After the video data passes through the signal processing circuit 35,
It is compressed by the MPEG video encoder 15 and transferred to the multiplexing / demultiplexing circuit 16.

Then, the system controller 28 performs CM detection using the position information of the silent portion and the position information of the scene change point stored in the RAM 30. Various methods have been proposed for CM detection, and one method will be described here.

For example, a CM included in a television broadcast program
Is a multiple of 15 seconds, and there is a scene change point where the scene changes significantly between CM.
That part is silent. Therefore, the system controller 28 analyzes the position information of the silent portion and the position information of the scene change point stored in the RAM 30 to find a section in which the above feature appears.

If this section is longer than a certain length, C
Determined as M section. Of course, the CM detection method is not limited to the method described here. For example, when flag information indicating a CM section is added to the supplied signal, the CM section can be specified by detecting this flag information. Also, a flag indicating the scene change position may be added,
You may make it specify a CM area using this scene change flag.

The CM section information thus obtained is sent to the multiplexing / demultiplexing circuit 16 by the system controller 28. The aforementioned audio data sent to the multiplexer / demultiplexer 16,
The video data and CM section information are multiplexed and sent to the buffer control circuit 17 and recorded on the optical disc 18. If the input source is the digital BS / CS tuner 1, in addition to the above data, character information data, screen information data, etc. are multiplexed and recorded.

As described above, in the recording / reproducing apparatus of this embodiment, the CM section which is the CM portion included in the broadcast signal such as the supplied television signal is detected, and the CM section of this CM section is detected. The CM section information indicating the position can also be recorded on the optical disc together with the video signal and the audio signal.

The CM section information is information that can specify the position of the CM section in the entire program, such as the address on the optical disc on which the CM section is recorded and the time information from the beginning of the program. Further, although it is conceivable that video signals and audio signals of a plurality of programs are recorded on the optical disc 18, the CM section information can also identify which program the CM section is.

[CM Providing Mode Using CM Section Information] Next, when reproducing the broadcast signal recorded on the optical disc, the CM section information recorded on the optical disc is used to reproduce the CM as described above. The process of controlling the provision mode of will be described.

The data read from the optical disk 18 is sent to the multiplexing / demultiplexing circuit 16 as video data, audio data,
It is separated into CM section information, character information data, screen information data, and the like. The CM section information is stored in the RAM 30 by the system controller 28, and is used in the calculation and determination described later.

OSD for character information data and screen information data
24. MPE for video and audio data
Data is expanded in the G audio / video decoder 19 and transferred to the post audio signal processing block 20 and the post video signal processing block 23, respectively.

In this embodiment, the MPEG audio / video decoder 19 is composed of two MPEG audio decoders 36 and 37 and two MPEG video decoders 38 and 39.

Each of the two decoders is configured to reproduce and display the CM video and the main video at the same time. If the decoder has more than double speed decoding performance, only one decoder is required. In that case, while the main part decoding and the CM decoding are performed alternately, the decoded data continues to be supplied to the memories 41 and 43, while the main part and the CM are synchronized, the two data are combined, and the subsequent stage is performed. It can be realized by outputting.

In the recording / reproducing apparatus of this embodiment, for example, the MPEG audio / video decoder 19
, The MPEG audio decoder 36 is for main program audio, and the MPEG audio decoder 37 is CM.
The audio, MPEG video decoder 38 is used for the main program video, and the MPEG video decoder 39 is used for the CM video under the control of the controller 28 based on the CM section information recorded in the RAM 30.

The post audio signal processing block 20 comprises a signal processing circuit 40 and a memory 41. The signal processing circuit 40 mixes the CM audio and the main audio, controls the audio reproduction start and end timings, and performs a fade process in order to realize the simultaneous reproduction display of the CM video and the main video described later. I am.

The post video signal processing block 23 comprises a signal processing circuit 42 and a memory 43. The signal processing circuit 42 performs screen composition of the CM video and the main video in order to realize simultaneous playback display of the CM video and the main video,
Filtering for noise removal is also performed.

The image data output from the post video signal processing block 23 is input to the OSD 24. OSD
In 24, character data and graphics for screen display according to the character information data and screen information data are generated,
It is added to the input image data and output.

The simultaneous reproduction display of the CM image and the main feature image will be specifically described below. FIG. 3 shows an example of recorded data when a certain program is recorded. This recorded data is 2
It is composed of book CMs and three main volumes divided by these CMs. Since the CM section is determined in advance at the time of recording, it is known at the time of reproduction how many CMs are present, and CM cut reproduction can be performed based on this information.

This state is shown in FIG. Main story 1 (between AB)
It is also possible that the main part 2 (between CDs) and the main part 3 (between EFs) are continuously reproduced, and CM1 (between BCs) and CM2 (between DEs) are not reproduced. CM cut reproduction as shown in FIG. 4 is a very attractive reproduction method for users, but it is a problem because advertisement sponsors and broadcasters cannot see CMs at all. .

Therefore, the recording / reproducing apparatus of the present invention realizes the simultaneous display / reproduction of the main part and the CM as follows. FIG. 5 is a diagram showing a reproducing operation when the present invention is applied, and FIG. 6 is a flowchart showing a processing method of the present invention. The description will be made with reference to FIGS. 5 and 6 and also with reference to FIGS. 2 and 3 as necessary.

First, when the reproduction key of the remote controller or the like is pressed, the system controller 28 of the recording / reproducing apparatus of this embodiment shown in FIG. 1 controls each part to make the object recorded on the optical disk 18. The reproduction of the main part of the broadcast program is started (reproduction from point A in FIGS. 3 and 5) (step S1).

Then, the system controller 28 uses C
It is checked whether or not the data has been reproduced up to the start point of the M section (step S2). While the AB portion of the main part 1 is being reproduced, the processing shifts from step S2 to step S6, from step S6 to step S9, and then returns to step S2 again. When the reproduction position reaches the point B shown in FIG. 3, it means that the reproduction has been performed up to the start point of the CM 1, and therefore the system controller 28 executes the process of step S3.

That is, the system controller 28
The respective parts are controlled so that CM1 (between BCs) shown in FIG. 3 is skipped and reproduction is performed from the starting point C of the main part 2 (step S3). At the same time, the system controller 28
The respective units are controlled to start the reproduction of the skipped CM1 (between BCs in FIG. 3) (step S4). Thus, as shown in FIG. 5, following the main story 1, the main story 2 and the CM 1 are simultaneously reproduced.

At this time, for example, the main audio data is input from the MPEG audio decoder 36 and the CM audio data is input from the MPEG audio decoder 37 to the audio signal processing circuit 40. To the video signal processing circuit 42, the main video data is input from the MPEG video decoder 38 and the CM video data is input from the MPEG video decoder 39. Then, the system controller 28
Controls each unit to synthesize the main part and the CM video and audio (step S5).

That is, in the audio signal processing circuit 40, the main part audio and the CM audio are mixed. For example, the main part sound and the CM sound are mixed one-to-one. The mix ratio is not limited to this, and the ratio of the sound of the main part may be increased or the ratio of the sound of CM may be increased.
Alternatively, only one of the sounds may be output.

In the video signal processing circuit 42, the main image and the CM image are combined. For example, a two-screen display format as shown in FIG. 7 and PinP (Pictur) as shown in FIG.
e inPicture) format. At this time, the main video and C
The display ratio of the M video may be arbitrary, and an effect such as zooming may be applied in the process of transition from the display of only the main video to the simultaneous display of the main video and the CM.

Then, the system controller 28 checks whether or not the CM being reproduced has ended (step S
6). When the reproduction of the CM 1 (between BCs shown in FIG. 3) is completed, the system controller 28 stops the reproduction of the CM (step S7), stops the display of the CM, and returns the display of only the main part (step S8). .

Then, the system controller 28 checks whether or not the reproduction of all the main parts has been completed (step S9). If the reproduction of all the main parts has not been completed, the system controller 28 returns to the processing from step S2 and controls each part so that the reproduction of only the main part is continued until the next CM start point.

In this way, the CM 2 shown in FIG. 3 is also simultaneously reproduced and displayed with the main part 3. When the reproduction reaches the point F of the main part 3, the reproduction of the main part is also stopped, and the process ends (step S10).

Here, as described with reference to FIGS. 7 and 8, the CM is shown to the user by simultaneously reproducing and displaying the main part and the CM. However, if you change the way of thinking here, the advertisement sponsors and broadcasters
The reason why I hate M-cut playback is that the commercial effect on the user is completely lost, and it can be convinced that whatever the advertising effect on the user, it will be convinced.

For example, in digital BC / CS broadcasting, character data information is sent in a stream, so if the demultiplexing / demultiplexing circuit 16 separates the character data information and sends it to the OSD 24, the character data information will be displayed in the video. Can be synthesized. By doing so, for example, as shown in FIG. 9, the CM can be displayed by character data instead of the CM video and audio.

FIG. 11 shows the flow of processing in the recording / reproducing apparatus when using this character data. As can be seen by comparing FIG. 11 and FIG. 6 described above, step S1
4, step S15, step S17, step S18
6, except that the CM character data is used instead of the CM video and audio, the other processing is as shown in FIG.
The processing is almost the same as the processing shown in.

Further, as shown in FIG. 10, the CM character data is used in addition to the CM image and sound, so that the main part, the CM image / audio, and the character CM are simultaneously reproduced. It is also possible.

When the CM section information can be read out separately from the TS signal, such as when the CM section information is recorded in a region different from the TS signal such as TOC, the optical disc is read. Immediately after being loaded in the recording / reproducing apparatus, the CM section information may be read and stored in the RAM 30.

Then, when the reproduction of the target program signal is instructed, the CM section information corresponding to the program signal previously read and stored in the RAM 30 is used to obtain C
It is possible to perform M-cut reproduction. That is, the CM section information is not limited to being read when the program signal is reproduced, but can be read and used at an appropriate timing.

[Various Modes of Execution Timing of Simultaneous Playback Display of Main Part and CM] In the above-mentioned method, the position where the CM was originally sandwiched triggered the main part and C
Simultaneous playback of M was displayed. It is also possible to display the main part and the CM at the same time at an arbitrary place designated by the user or at a position designated in advance by the advertisement sponsor or the broadcaster. In the following, the main part and CM
Various aspects of execution timing of simultaneous reproduction display with and will be described.

FIG. 12 shows an example of recorded data when a broadcast signal of a certain program is recorded on the optical disc by the recording / reproducing apparatus shown in FIG. This recorded data consists of 4 CMs
(CM1 to CM4) and three program main parts (main part 1 to main part 3) divided (divided) by CM. In the following, various aspects of the execution timing of the simultaneous reproduction display of the main part and the CM will be described by taking the case of reproducing the recorded data shown in FIG. 12 as an example.

[Method of Simultaneously Reproducing and Displaying Main Part and CM at Arbitrary Time] First, the case where the simultaneous replay and display of main part and CM is performed at an arbitrary time will be described. 13 and 14
FIG. 6 is a diagram for explaining an example of a case where the main part and the CM are simultaneously reproduced and displayed at an arbitrary time point. As shown in FIG. 13, for example, when it is desired to disperse and reproduce CMs in the entire main part including main part 1, main part 2, and main part 3, or as shown in FIG. There are times when you want to let it.

In such a case, the CM reproduction flag is used. This CM playback flag was originally CM
This is a flag prepared to start the CM reproduction regardless of the position where there was a problem, for example, when the CM reproduction key prepared on the remote controller is pressed, or it is sent from the broadcaster together with the program. It is set by the system controller 28 when there is time designation information for CM reproduction.

When reproducing the video signal or audio signal of the main part in which the CM reproduction flag is set, the CM is reproduced at the same time as the reproduction of the main part.
It is possible to simultaneously reproduce the main part and the CM as shown in FIG. That is, FIG. 13 shows a case where the CM reproduction flags are set to be dispersed, and FIG. 14 shows that the CM reproduction flags are
This is the case when they are set in quick succession.

[Method of playing back all CMs by the end of the main part]
Next, a method for surely ending the simultaneous reproduction display of all CMs until the end of the main story will be described. The recording / reproducing apparatus according to the present invention is intended to allow the user to see the CM firmly while improving the convenience and comfort of the user by the CM cut reproduction, and the reproduction of all the main parts of the program is completed. By then, all commercials contained in the program must also be played.

However, when the recorded program is the one recorded as shown in FIG. 12, the CM4 can be reproduced by the time the reproduction of all the main parts is completed only by performing the processing described above with reference to FIG. And cannot be displayed simultaneously.
This is because CM4 is located at the end of the program. Therefore, this is solved by comparing the remaining time of the main part that has not yet been reproduced with the remaining time of the commercial.

Specifically, the system controller 28 of the recording / reproducing apparatus grasps the reproduction time of all the main parts and the reproduction time of all the CMs, and at the time of reproduction, the reproduction remaining time of the main part and the reproduction remaining time of the CM are always maintained. And monitor. Usually, the remaining time of the main story is longer than the remaining time of the commercial.

However, when the remaining time of the main part becomes equal to the remaining time of the CM, the reproduction of the CM is immediately started, and the main part and the CM are simultaneously reproduced and displayed. By performing such processing, for example, as shown in FIG. 15, the simultaneous reproduction display with the main part of CM 4 can be completed before the reproduction of main part 3 is completed.

Further, as described above, in the case where the CM reproduction position is arbitrarily controlled by the user's designation and the user does not specify the CM reproduction forever, the present processing method is applied, For example, as shown in FIG. 16, all the CMs can be forcibly reproduced and displayed at the same time, and all the CMs can be surely reproduced at the same time as the main part to be shown to the user.

Further, as shown in FIG. 15, basically, the simultaneous reproduction display with the CM is performed at the beginning part of each main part, as shown in FIG. It is also possible to display the main part and the CM at the same time in the part.

[Suspension and Resumption of Reproduction] The processing method in the case where the reproduction is stopped by the user during the simultaneous reproduction and display control of the main part and the CM by the processing method so far will be described. Even if the playback is stopped,
Next, it is necessary to record information about how much has been reproduced for each of the main part and the CM so that the continuation of the previous processing can be executed again when the reproduction of the program is started.

Therefore, when the reproduction stop key is pressed, the reproduction history information indicating how far the main part and the CM have been reproduced at that time is recorded. The reproduction history information is written in the RAM 30 by the system controller 28. Then, when the reproduction is resumed by pressing the reproduction key of the remote controller or the like, the system controller 28 reads the reproduction history information from the RAM 30,
The reproduction is restarted based on the reproduction history information.

FIG. 18 shows the operation when the reproduction is stopped during the processing of FIG. In this example, the main part ends the reproduction of the main part 1 and the main part 2 up to the point X, and the CM is the CM.
It is recorded as reproduction history information that reproduction of 1 and CM 2 is completed. After the reproduction is resumed, as shown in the lower part of FIG. 18, the state before the reproduction is stopped is taken over, and the main reproduction and the CM are simultaneously reproduced and displayed.

FIG. 19 shows the operation when the reproduction is stopped during the processing of FIG. In this example,
It is recorded as the reproduction history information that the reproduction of the main volume to the point Y of the main volume 1, the main volume 2 and the main volume 3 is completed, and the reproduction of the CM to the Z point of CM1, CM2 and CM3 is completed. After the reproduction is resumed, the state before the reproduction is stopped is taken over as shown in the lower part of FIG.
Even in such a case, it is possible to surely reproduce and display all the CMs at the same time until the end of the main story.

The reproduction history information is stored in the RAM before the optical disc 18 is ejected or before the power of the apparatus is turned off.
30 to system controller 28, multiplexing / demultiplexing circuit 1
6, and is transferred to the optical disk 18 through 6.

Again, after the power of the apparatus is turned on or the optical disc 18 is loaded, the optical disc 18 is loaded.
The reproduction history information is transferred from the RAM to the RAM 30. As a result, even when the reproduction of the program recorded on the optical disc that has been ejected from the recording / reproducing apparatus of this embodiment is resumed, it can be properly resumed as shown in FIGS. 18 and 19. .

[Summary of operation of recording / reproducing apparatus] Next, as described above, the CM reproduction flag can be used to simultaneously reproduce and display the main part and the CM, and during the main part reproduction period. With reference to FIGS. 20 and 21, the operation of the recording / reproducing apparatus of this embodiment capable of surely reproducing and displaying all the CMs at the same time as the main part, and capable of properly performing the reproduction interruption and the reproduction restart explain.

First, when a reproduction key such as a remote controller is pressed, the system controller 28 of the recording / reproducing apparatus of this embodiment reads reproduction history information from the RAM 30 (step S21). Then, when the reproduction history information exists, the reproduction is started from the position on the optical disc 18 corresponding to the reproduction history information, and when the reproduction history information does not exist, the reproduction is started from the head of the target program data (step S22).

When the optical disk is ejected from the recording / reproducing apparatus, the reproduction history information is written in a predetermined position such as TOC of the optical disk ejected from the RAM 30, as described above. And
When this optical disc is newly loaded in the recording / reproducing apparatus, the system controller 28 reads the reproduction history information from the optical disc, stores it in the RAM 30, and makes it available.

Then, the system controller 28 determines whether or not the reproduction stop key has been operated (step S2).
3), when it is determined that the playback stop key has been operated,
The reproduction history track information is acquired and recorded in the RAM 30 (step S40), the process proceeds to step S34 shown in FIG. 21, and the reproduction of the main part is stopped.
The reproduction process shown in 1 is ended.

When it is determined in step S23 that the reproduction stop key has not been operated, the system controller 28 determines that the remaining C which has not been reproduced yet.
The M time (commercial remaining time) is compared with the entire main part time (all main part remaining time) that has not yet been reproduced, and it is determined whether or not both are equal (step S24).

When it is determined in step S24 that the CM remaining time and the main program remaining time are not equal, the system controller 28 determines that the program data being reproduced is
It is determined whether the start point of the CM section has arrived (step S25). In the determination processing of step S25, CM
When it is determined that the start point of the section has arrived, the system controller 28 jumps the CM to reproduce the main part (step S26) and separately starts the reproduction of the jumped CM (step S).
27).

Then, the system controller 28 uses C
The M reproduction flag is reset (step S28), and the video and audio of the main part and the video and audio of CM are synthesized and output (step S29). That is, the main part and the CM are simultaneously reproduced and displayed.

When it is determined in step S25 that the start point of the CM section has not arrived, the system controller 28 determines that the data currently being reproduced is
It is determined whether the CM reproduction flag is set (step S35). When it is determined in step S35 that the CM reproduction flag is set, the system controller 28 executes the processing from step S27, and performs the simultaneous reproduction display of the main part and the CM as described above.

After step S29, or step S
If it is determined in the determination processing of step 35 that the CM reproduction flag is not set, the system controller 2
The process proceeds to step S30 shown in FIG. 21, and it is determined whether the reproduction of one CM section is completed (step S3).
0).

In the judgment processing of step S30, CM
When it is determined that the reproduction of one section is completed, the system controller 28 controls each unit, stops the reproduction of the CM (step S31), and continues the reproduction of only the main part (step S32).

After the processing of step S32, and when it is determined in step S30 that the reproduction of one CM section has not ended, the system controller 28
It is judged whether or not the reproduction of all the main parts is completed (step S3
3) When it is determined that the process is finished, the respective units are controlled to stop the reproduction of the main part (step S34), and the process shown in FIG.
0, the processing shown in FIG. 21 ends. In the process of step S33, when it is determined that the reproduction of all the main parts is not finished, the process from step S23 shown in FIG. 20 is repeated.

Further, in the determination processing of step S24 shown in FIG. 20, when the CM remaining time and the main program remaining time become equal, the system controller 28 causes the system controller 28 shown in FIG.
The process proceeds to step S36 shown in step S36. First, each unit is controlled so as to reproduce the CM that has not been reproduced yet (step S36), and the video and audio of the main part and the video and audio of the CM are synthesized and output. Yes (step S37). That is, the main part and the CM are simultaneously reproduced and displayed.

Then, the system controller 28 uses C
It is determined whether or not the reproduction of the M section has been completed (step S38). This judgment is made because once the remaining time of the main part and the remaining time of the commercial become equal, after that, all the remaining commercials must be continuously reproduced in succession.

In the judgment processing of step S38, CM
When it is determined that the reproduction of one section has been completed, the system controller 28 controls the related units so as to jump to the next CM so as to perform the simultaneous reproduction display of the next CM and the main part (step S39). ).

After the processing of step S39, or when it is determined in the determination processing of step S38 that the reproduction of one CM segment has not ended, the system controller 28 proceeds to the processing of step S33, and as described above. , It will be determined whether or not the reproduction of the entire main part is completed.

As described above, in the recording / reproducing apparatus of this embodiment, the CM which is broadcast alternately with the main part is reproduced and displayed at the same time as the main part, so that the user can surely watch the CM. be able to. Moreover, since the main part and the main part can be continuously reproduced, the convenience for the user can be improved.

As can be seen from the above description, at the time of recording, the recording / reproducing apparatus according to the present embodiment has address information on a recording medium capable of specifying the position of the CM section in the entire program, and The time from the beginning of the program can be recorded as CM section information, and
It is possible to grasp the entire time of the main program section and the time of the CM section.

When the program recorded on the optical disk 18 is reproduced, the time of the main program section not reproduced (main program remaining time) and the time of the CM section not reproduced (C
M remaining time) can be calculated and managed. That is, the recording / reproducing apparatus of the above-described embodiment is
It is provided with a clock circuit or a counter for managing time.

Also. The reproduction history information is information that can specify the address indicating the recording position on the optical disc of the main section and CM section to be reproduced next, such as the address information on the optical disk that indicates the recording position of the main section and the CM section where reproduction is interrupted. Is.

Further, the reproduction order of the CM sections is not limited to the order in which they are inserted in the program, but can be changed in any order.

The present invention is not limited to what has been described in the above-described embodiment, and various modifications such as the following are possible.

For example, a magnetic disk, a magneto-optical disk,
The present invention can be applied to a recording / reproducing apparatus using any storage medium such as an HDD and a semiconductor memory.

Further, the position information of the CM section, the reproduction history information indicating how much the main part and the CM are reproduced,
Instead of the optical disc 18, the RAM 30 may be kept stored. In addition, a new non-volatile memory etc. is prepared,
It can be stored and managed there.

The compression method of image data and audio data does not have to be MPEG2, and any other compression method may be used. Further, it may remain uncompressed.

The character data information is not limited to that sent as a stream like digital broadcasting,
In the case of analog broadcasting, the acquisition source is not limited, such as information superimposed on the synchronization signal, and it is possible to support various cases.

Further, although the recording / reproducing apparatus is configured in the above-described embodiment, a CM section other than the main program section can be detected, and a section indicating the detected section other than the main program section. It is also possible to configure a recording-only machine capable of recording information on a recording medium.

When a recording medium in which section information indicating a section other than the main program is recorded is loaded and the program recorded in the recording medium is reproduced from the recording medium, as in the recording / reproducing apparatus described above, It is also possible to configure a reproduction-only machine that reproduces a signal section other than the main program section at the same time as the main program section.

Further, in the above-described embodiment, the signal section other than the program main section is described as a CM section. However, the signal section other than the main program section is not limited to the CM section. For example, a portion other than the main program section inserted in the program such as temporary news, traffic information, and weather forecast is detected, and this section is detected. By recording the information indicating the above, it is possible to reproduce the signal section other than the CM at the same time as the main program.

It should be noted that detection of signal sections such as temporary news, traffic information, and weather forecasts inserted in a program may be detected according to the characteristics of the respective signal sections, or may be added to the signal of the program. It can be detected by detecting a pilot signal or the like indicating a signal section other than the provided main program.

In the above embodiment, the terrestrial tuner or the analog audio input terminal 5,
The CM section of the program signal supplied through the analog video input terminal 6 is detected. However, it is not limited to this.

For example, digital BS / CS tuner 1
With respect to the digital program signal supplied through the digital input / output terminal 2 or the digital input / output terminal 2, the main program part and the CM part added to the program data in the preceding stage of the multiplex / separation circuit 16 or in the multiplex / separation circuit 16 are distinguished. It is possible to detect the CM section based on the flag information for recording, record the information indicating this section on the recording medium, and use it during reproduction.

If the input is digital data that has been data-compressed, the data may be compressed and decompressed, the CM section may be detected, and the data may be compressed again and recorded. If information indicating which part is the main program and which part is the CM part is added to the input digital data, it is added without detecting the CM section. Using the data, the CM cut reproduction can be performed as in the case of the reproduction described above.

Further, the detection of the CM section is not limited to that described above, and various methods can be used. For example, the CM section may be detected only from the video signal, or the CM section may be detected only from the audio signal.

Therefore, the CM section is detected for the program signal only of the video signal or the audio signal,
By recording the CM section information indicating the position of the CM section on the recording medium, the CM is cut and reproduced in the same manner as in the case of the recording / reproducing apparatus described above, and the CM is reproduced simultaneously with the main part. You can
