DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a broadcast program transmitting / receiving system for transmitting a predetermined broadcast program including video information and audio information from a predetermined transmitting device in a broadcasting station to a receiving / reproducing device in each region, a transmitting device, The present invention relates to a broadcast program transmission method, a reception / playback apparatus, a broadcast program playback method, and a recording medium.

[0002]

2. Description of the Related Art In recent years, digital communication technology has been remarkably developed, and a broadcast program transmitting / receiving system for transmitting / receiving a broadcast program has reached a major turning point.

Conventionally, in terrestrial television broadcasting and the like, video signals and audio signals are transmitted as analog radio waves from a broadcasting station.
The radio wave was received by the television receiver to reproduce the video and audio.

On the other hand, recently, so-called digital communication broadcasting, in which video and audio are broadcast as digital signals through a wireless communication path or a wired communication path, has been implemented.

[0005] This digital communication broadcasting mainly consists of broadcasting of a digital television program that broadcasts digital video signals and audio signals as information elements.
When a broadcast program is recorded on the user (viewer) side and the broadcast program is reproduced later, handling the broadcast program as digital data facilitates the handling.
Also, since large-capacity communication is possible, various data other than video and audio can be transmitted together from the broadcast station side.
There is an advantage that transmission of information and the like accompanying the broadcast program becomes easy.

[0006]

When a user is not present at a predetermined broadcast time, a recording reservation of a broadcast program is made on the basis of time counting by a timer provided in the recording device, and the answering machine is recorded. In addition, it is possible to watch a broadcast program at a desired place at a desired time later. However, when the number of recorded broadcast programs increases, a large amount of time is required to collectively reproduce the broadcast programs later, and the reproduction may be troublesome and the opportunity to view may be missed. In particular, even though not all of the answering machine-recorded programs are worth watching from the beginning to the end, if the user does not watch all the answering machine-recorded broadcast programs, it is difficult to determine whether the user has the desired content. Therefore, there is a request from a user who wants to view only a partially interesting scene and judge whether or not he / she wants to actually watch the scene from the contents.

[0007] For example, in the case of recording on an analog type time lapse video or the like, it is possible to perform so-called frame advance to reproduce a video at a higher speed than usual. Alternatively, there are devices capable of viewing recorded video with relatively high quality and high speed reproduction.

However, in these cases, the recorded video is reproduced uniformly from the beginning to the end. In order to roughly grasp the entire content structure, it is necessary to reproduce the excessive video. No. Therefore, it is hard to say that the method is time-efficient.

In view of such a situation, a method has been disclosed in which, after a broadcast program is once recorded in a predetermined recording device, only a predetermined digest scene is reproduced (Japanese Patent Laid-Open No. Hei 8-2).
No. 94083). According to this method, since a digest is created by displaying a list of representative frames extracted from one continuous scene, only a predetermined digest scene of the recorded video can be displayed on the display device. In addition, it is possible to easily confirm whether or not a broadcast program or the like recorded by answering machine is worth watching, and it is possible to reduce a time burden on the user.

However, in this method, it is not easy to change the setting of the digest scene in the broadcast program.

An object of the present invention is to provide a broadcast program transmission / reception system capable of easily changing a reproduction time or a reproduction content in reproducing only a digest scene in which a user can quickly grasp the content structure of an answering machine recorded program. , A transmission device, a broadcast program transmission method, a reception / playback device, a broadcast program playback method, and a recording medium.

The broadcast wave selected by the tuning circuit 32 is transmitted by the demodulation circuit 33 to the transmitting device 1.
The demodulation process corresponding to the transmission modulation device 14 is performed to convert the broadcast wave into the video frame data 12a and the audio data 12b.
(See FIG. 4 or FIG. 5), perform predetermined demodulation processing, and output.

Of the various data demodulated by the demodulation circuit 33 in this manner, the video frame data 12a is subjected to processing such as descrambling and deinterleaving in the decoding circuit 34 to return to the original code string. Performs error correction and bit decompression, etc.
Is performed to return to the original video information 11a. In addition, the decoding circuit 34 outputs the audio data 12b.
The PCM subcarrier is extracted through a bandpass filter, converted into a digital signal of a PCM code string, and returned to the original audio information 11b in the information source 11.

The video information 11a output from the decoding circuit 34 of the tuner / decoding circuit 21 is adjusted by a video signal processing unit 41 of the information editing processing unit 22 to a synchronization signal, a luminance signal, a color difference signal, and the like. It is converted into a moving image signal. The audio signal processing section 42 also performs predetermined processing such as noise removal on the audio information 11b. Preferably, the audio signal processed by the audio signal processing unit 42 is
The video signal processed by the video signal processing unit 41 is associated with each frame or every fixed number of frames.

The video signal and the audio signal output from the information editing processing section 22 are output to the recording device 46 according to the user's request.
Will be recorded. In this case, the remote controller 24
The recording may be instructed to the recording device 46 through the control unit 23, or the recording may be instructed by pressing a recording button or the like provided on the recording device 46 itself. Here, the information is recorded on the recording device 46 by directly storing and recording the video signal output from the video signal processing unit 41 and the audio signal output from the audio signal processing unit 42. For the video signal related to the frames belonging to the digest scene of the above, the digest flags Df1 and Df2 are added to the header of each frame.
Recording is performed in a state where (the small amount digest flag Df1 or the large amount digest flag Df2) is added.

If the user wants to output a broadcast program from the information editing processing unit 22 and reproduce it, the information editing processing unit 2
Display device 3 for the video signal output from
The predetermined signal processing is performed by the image processing circuit 51 of
In addition to displaying an image on the speaker 2, the audio signal supplied from the audio signal processing unit 42 is amplified by the amplifier 53 and output to the built-in speaker 54.

Next, when the user wants to view the broadcast program once recorded in the recording device 46 as it is, the user operates the remote controller 24 to operate the information editing processor 22.
The digest mode switching unit 41a is set to the normal reproduction mode, and the user operates the remote controller 24 or the predetermined operation button of the recording device 46 to perform the operation.
The video signal and the audio signal recorded in the recording device 46 are input to the video signal processing unit 41 and the audio signal processing unit 42.
After performing predetermined processing in the video signal processing unit 41 and the audio signal processing unit 42, the video is displayed on the display unit 52 through the image processing circuit 51 of the display device 3, and the audio signal is amplified by the amplifier 53. Built-in speaker 5
4 is output.

Here, when the user wants to view only the digest scene, the user operates the remote controller 24 to set the digest mode switching unit 41a of the information editing processing unit 22 to a desired one of the small digest mode and the large digest mode. And the digest mode switching section 41a of the information editing processing section 22 is switched to the small digest mode or the large digest mode. When the mode switching is performed, the digest scene detecting unit 41b sets the digest flag Df related to the desired digest mode added to the header part for each frame in the video signal recorded in the recording device 46.
1, and Df2 are detected in time series, and while digest scenes are extracted, these are sequentially output and displayed on the display device 3. When the audio signal in the recording device 46 is associated with the video signal in a time-series manner, the audio signal corresponding to the digest scene detected and extracted by the digest scene detection unit 41b is output to the audio signal processing unit. 42
To the speaker 54 through the amplifier 53 in the display device 3.

In this way, it is possible to easily confirm whether or not the broadcast program once recorded in the recording device 46 is worth watching, and it is possible to reduce the time burden on the user. In particular, if the user does not have much time to spare, specify the small digest mode.If the user has relatively little time, designate the large digest mode. Just by switching, the playback time of the digest scene can be easily changed.

{Second Embodiment} In the above-described first embodiment, all digest scenes have to be determined in advance on the broadcast station side and digest flags Df1 and Df2 have to be set. On the other hand, in the second embodiment, the digest is automatically reproduced on the receiving / reproducing apparatus 2 side according to the user's request without using the digest flags Df1 and Df2 described in the first embodiment. It is made possible. Note that, in this embodiment, elements having the same functions as those in the first embodiment are denoted by the same reference numerals.

More specifically, as shown in FIG. 7, the receiving / reproducing apparatus in the broadcast program transmitting / receiving system uses commercial-message (CM) CM0-CM
4 is inserted, the CM (CM0 to CM
4) and the boundary time between the broadcast program images P1 to P4 as reference timings Tc0 to Tc4.
Scenes from 0 to Tc4 to a certain time (first time: for example, “1 minute”) tca are digest scenes D in a small amount.
ca (a hatched portion in FIG. 7), and a fixed time (second time: for example, “3 minutes”) tcb longer than the first time tca from the reference timings Tc0 to Tc4.
A large amount of the digest scene Dcb (the hatched portion and the hatched portion in FIG. 7).
When a user designates one of the digest modes and performs digest reproduction for a broadcast program once recorded, first, CM (CM0 to CM4)
Time points (reference timings) Tc0 to Tc4 between the data and the broadcast program images P1 to P4 are detected in time series, and the first time tca or the second time corresponding to the digest mode designated from the reference timings Tc0 to Tc4. tc
By playing back only b images in time series,
The reproduction time of the digest scenes Dca and Dcb can be easily changed.

Here, the configuration of the transmitting apparatus 1 in this embodiment is the same as that of the first embodiment described with reference to FIG. 1, except that the header 12c includes the digest flags Df1 and Df2. They differ in that they do not need to.

As shown in FIG. 8, a digest mode switching unit 41a is installed in the video signal processing unit 41, and the broadcast program (CM) once recorded in the recording device 46 is configured as shown in FIG. CM (C)
M0 to CM4) and a reference timing detection unit 41c for sequentially detecting the boundary time points between the broadcast program images P1 to P4 in time series.
The time from the reference timing is changed according to the digest mode (the small amount digest mode or the large amount digest mode) switched by the digest mode switching unit 41a, and the respective digest scenes Dca, D
a time changing unit 41d for extracting cb. The reference timing detecting section 41c and the time changing section 41d constitute a digest scene extracting means for extracting a small digest scene or a large digest scene and outputting the digest scene to the display device 3.

Here, the digest mode switching section 41a
Are the same as those of the first embodiment, and therefore the description is omitted.

The detection of the reference timing by the reference timing detection section 41c is based on a change in the audio level of the audio signal associated with the video signal in the recording device 46.
There are a method of recognizing a boundary between M (CM0 to CM4) and the broadcast program video P1 to P4, a method of detecting a reference timing based on information of a header part for each frame in a video signal as a digital signal, and the like. However, any method can be used. The reference timing detection unit 41c sequentially detects the video signal corresponding to the reference timing in a time-series manner in the information in the recording device 46, and outputs the detected video signal of the reference timing to the recording device 46.
And outputs it to the display device 3 until the time measurement by the time change unit 41d is completed.

Further, the time changing section 41d includes a first time tca and a second time tca set in advance as shown in FIG.
cb is selected based on the switching by the digest mode switching unit 41a, and at the time when the time of the reference timing is detected with respect to the video information 11a in the recording device 46, the time counting by the built-in timer 41e is started, This time measurement result is compared with the first time tca or the second time tcb selected earlier, and when the time measurement result exceeds the first time tca or the second time tcb, the output of the video signal to the display device 3 is stopped. In addition, it has a function of instructing the reference timing detection unit 41c to transfer the processing to the next reference timing in a time series.

The other components in the receiving and reproducing apparatus 2 are the same as those in the first embodiment shown in FIG.

The following operation is performed in the receiving and reproducing apparatus 2 of this embodiment.

First, when a transmission wave is transmitted from the transmission device 1, the reception and reproduction device 2 installed in a general home receives the transmission wave by the reception circuit 31 of the tuner / decode circuit 21 as shown in FIG. I do.

Here, the user operates the channel selection circuit 32 through the control unit 23 by operating the remote controller 24.
Is operated to select a broadcast wave of a desired reception channel, and after undergoing demodulation processing in a demodulation circuit 33, the broadcast wave is decomposed into video frame data 12a and audio data 12b and output. The demodulated video frame data 12a and audio data 12b are decoded by the decoding circuit 34 and returned to the original video information 11a and the original audio information 11b.

The video information 11a output from the decoding circuit 34 of the tuner / decoding circuit 21 is adjusted by a video signal processing section 41 of the information editing processing section 22 to a synchronization signal, a luminance signal, a color difference signal, and the like. It is converted into a moving image signal. The audio signal processing section 42 also performs predetermined processing such as noise removal on the audio information 11b. Preferably, the audio signal processed by the audio signal processing unit 42 is
The video signal processed by the video signal processing unit 41 is associated with each frame or every fixed number of frames. The video signal and the audio signal output from the information editing processing unit 22 are recorded in the recording device 46 as desired by the user.

Next, when the user wants to reproduce only the digest scene of the broadcast program once recorded in the recording device 46, the user operates the remote controller 24 to
The user designates a desired one of the small digest mode and the large digest mode, and switches the digest mode switching unit 41a of the information editing processing unit 22 to the small digest mode or the large digest mode.

At this time, the reference timing detector 41c
Detects a video signal in the recording device 46 corresponding to the reference timing (for example, reference symbol T0 in FIG. 7), outputs the video signal to the display device 3, and outputs the digest scenes Dca and Dcb.
Start playing. At the same time, the timer 41e of the time changing unit 41d starts measuring time. Then, the time changing unit 41d
Is a first time tca set in advance as shown in FIG.
And the second time tcb is selected based on the switching by the digest mode switching unit 41a,
The measurement result at 1e is continuously compared with the previously selected first time tca or second time tcb. Then, when the time measurement result exceeds the first time tca or the second time tcb,
The output of the video signal to the display device 3 is stopped. At the same time, it instructs the reference timing detection unit 41c to transfer to the processing of the next reference timing in a time series from the video signals in the recording device 46.

When the audio signal in the recording device 46 is associated with the video signal, the digest scene D
The audio output from the speaker 54 is also performed in synchronization with the video reproduction of the display device 3 of ca and Dcb.

In this way, for the video signal once recorded in the recording device 46, for example, if the user does not have much time, the small amount digest mode is designated, and if the user has relatively little time, The user can easily change the digest scene playback time by simply switching to a digest mode according to the user's request, such as specifying a large number of digest modes. Moreover, since it is not necessary to add the digest flags Df1 and Df2 in advance as in the first embodiment, the work of the broadcast program creator can be greatly reduced. Especially the video before and after the CM,
Since the story of a broadcast program tends to be unfolded significantly, a small amount of video after CM is collected as digest scenes Dca and Dcb to compose a digest, and a digest that expresses the story unfolding automatically is automatically created. There is an advantage that it can be reproduced.

In a normal broadcast, a predetermined video and audio called an eye catch may be played before and after a CM. The eye catcher always plays the same video and audio irrespective of the story of the broadcast program, and is a signboard part of the broadcast program. Therefore, since it is an unnecessary part mainly for the digest for quickly knowing the story of the broadcast program, it is desirable to treat this eye catch as a CM and not to include it in the digest scene.

By the way, each of the digest scenes Dca and Dcb described in this embodiment is limited to the digest scenes Dca and Dcb after the CM, but the image portions after the CM (the digest scenes Dca and Dc)
In addition to b), a small amount of digest scene Dcc and a large amount of digest scene Dcd can be defined for the video portion before the CM as shown in FIG. 9 and detected from the video information 11a in the recording device 46. In, a small digest scene Dcc before the CM for 30 seconds,
30 seconds for a small digest scene Dca after CM
For example, it is possible to reproduce the digest before and after the CM by defining the preceding large-capacity digest scene Dcd as 2 minutes and the large-capacity digest scene Dcb after the CM as 1 minute.

{Third Embodiment} In this third embodiment, the contents of each scene of a broadcast program are determined in a predetermined manner instead of using the digest flags Df1 and Df2 described in the first embodiment. The content is designated in association with the video by the content designating code described above, and based on this, only the video of this content is extracted on the receiving / reproducing apparatus 2 side, and this is reproduced as a digest. Note that, in this embodiment, elements having the same functions as those in the first embodiment are denoted by the same reference numerals.

That is, the broadcast program creator, in the video information 11a in the information source 11 of the transmitting device 1,
A content designating code corresponding to the video content, such as information on the performer (cast) and information on the scene such as "action scene" and "love scene", is determined, and the content designating code is stored in the header portion for each frame. Include it. The content designation code is an international program classification (IPC) generally used in the broadcasting industry for classifying broadcast content into genres such as drama, music, and news. Is assigned to each content and used. The association between the content designating code and the program content is distributed to each user in advance through a predetermined booklet or the like.

In this embodiment, in the receiving / reproducing apparatus 2, the user can designate any one of the content designation codes. A small digest mode in which only the given video frame (hereinafter referred to as a “content designation frame”) is selected and reproduced as a small digest scene (reference numeral Dd in FIG. 10). It is possible to switch between a large-capacity digest mode for reproducing as a large-capacity digest scene (denoted by De in FIG. 10) including a video having a certain margin time.

Here, the designation of the content designation code is performed by the remote controller 24 shown in FIG. 1, and the digest scene detection in the video signal processing section 41 of the information editing processing section 22 through the infrared light receiving element 25 and the control section 23. The digest scene detection unit 4
1b detects a corresponding video frame of the video information 11a in the recording device 46 using the content designation code as a key. In particular, when the large-capacity digest mode is set, after detecting the frame to which the content designation code is added (the small-capacity digest scene Dd), a predetermined number of frames (for example, the number corresponding to one minute) before and after the frame are detected. Also digest scene (mass digest scene D
e).

The components of the transmitting apparatus 1 and the receiving / reproducing apparatus 2 in this embodiment are different from the digest flags Df1, Df1 in that the content specifying code is used as described above.
Although it is different from the first embodiment using Df2, the other device configuration is substantially the same as that of the first embodiment, and the description thereof is omitted.

The operation of this embodiment will be described.

First, on the broadcast station side, the program creator determines that the video information 11a and the audio information 11b
Is created, a content designating code based on an international program classification or the like is added to the header portion of each frame of the video information 11a. The content designating code includes, for example, information on cast (cast) and "action". Information such as an outline of a scene such as “scene” and “love scene” is included. The transmission device 1 includes the content specifying code.
Is transmitted to the receiving and reproducing apparatus 2.

When a transmission wave is transmitted from the transmission device 1, the reception / reproduction device 2 installed in a general home or the like receives the transmission wave and displays it on the display device 3 or records it in the recording device 46. .

Next, when the user wants to reproduce only the digest scene of the broadcast program once recorded in the recording device 46, the user operates the remote controller 24 to
The user designates a desired one of the small digest mode and the large digest mode, and switches the digest mode switching unit 41a of the information editing processing unit 22 to the small digest mode or the large digest mode. At this time, the user also inputs, via the remote controller 24, a content designation code indicating a favorite cast (cast) or the like.

When the mode switching is performed, the digest scene detecting section 41b converts the digest scene based on the content designation code given to the header part for each frame in the video signal recorded in the recording device 46. While extracting, it is output and displayed on the display device 3 sequentially.

That is, when the user designates the small amount digest mode, the user
Based on the content designating code specified and input through, only the content designating frame is selectively extracted from the video information in the recording device 46, read as a small amount digest scene (code Dd in FIG. 10), and output and reproduced on the display device 3. I do. Then, for example, when the user designates a favorite performer as a content designation code, all scenes (content designation frames) in which the designated performer appears are extracted from all the videos of the broadcast program and reproduced. it can.

On the other hand, when the user designates the large amount digest mode, after detecting the contents designation frame (small amount digest scene Dd) based on the contents designation code,
Further, it includes a certain number of frames before and after that and reproduces and reads them as digest scenes (mass digest scenes De), and outputs and reproduces them on the display device 3 as more detailed digest scenes (mass digest scenes De). Then, for example, when the user specifies a favorite performer as the content specifying code, not only can all scenes (content specifying frames) in which the specified performer appear from all the videos of the broadcast program be extracted. , A certain number of frames before and after that can be displayed. Therefore,
It is possible to display the details of the scenes and the like in which the performer is appearing in more detail, while reducing the time and reproducing the digest with a particular performer as the center.

<< Fourth Embodiment >> A broadcast program transmission / reception system according to a fourth embodiment of the present invention enables a user to arbitrarily change the time settings of individual digest scenes as desired by the user. It is. FIG. 11 shows the lengths tg1 to dg1 of the digest scenes Dg1 to Dg8 and Dh1 to Dh8 generated based on the time settings specified by the user in the broadcast program images P1 to P4 in the fourth embodiment.
It is a timing chart which shows tg8 and th1-th8. Reference signs Dg1 to Dg8 indicate a small amount digest scene, and reference signs Dh1 to Dh8 indicate a large amount digest scene.

In this embodiment, based on reference timings T0 to T4 at predetermined time intervals when broadcast program images P1 to P4 progress in chronological order, the preceding and succeeding images are digested into digest scenes Dg1 to Dg8, Dh1 to Dh1. At this time, the length of each of the digest scenes Dg1 to Dg8 and Dh1 to Dh8 can be easily changed based on the operation of the remote controller 24 by the user. .

Here, the appearance of the remote controller 24 is shown in FIG. This remote control 24
Means a liquid crystal display element or electroluminescence (E
L) Display panel 24 using an image display element such as an element

FIG. 9 is a diagram illustrating an example of a state in which the length of the image is changed.

Reference numeral 61 in FIG. 13 indicates a progress line of a broadcast program, and the time elapses from left to right. The vertical axis of FIG. 13 shows a time difference from the reference timing 61 when each time point of the progress line 61 of the broadcast program is set as the reference timing, and the time earlier than the reference timing 61 is the progress of the broadcast program. The position is higher than the line 61, and the higher the position, the higher the position. The time after the reference timing 61 is located below the progress line 61 of the broadcast program, and the longer the time difference is, the lower the time is.

Reference numeral 62 in FIG. 13 indicates a small amount of digest scene immediately before this reference timing (reference numerals T1 to T4 in FIG. 11) 61 when each point of the progress line 61 of the broadcast program is used as a reference timing. Dg2, Dg4, Dg
6 is an initial line showing the initial state of the timing of Dg8. In the example of FIG. 13, these small digest scenes Dg2 and Dg2 are initially set one minute before the reference timing 61.
It means that Dg4, Dg6, and Dg8 are started. Further, reference numeral 63 in FIG. 13 is an initial line indicating an initial state of the timing of the small amount digest scenes Dg1, Dg3, Dg5, Dg7 immediately after the reference timing (reference numerals T0 to T3 in FIG. 11). In the example, it means that these small digest scenes Dg1, Dg3, Dg5, and Dg7 end at one minute after the reference timing 61. That is, in the example of FIG. 13, all the digest scenes Dg1 to Dg8, D
The lengths tg1 to tg8 and th1 to th8 of h1 to Dh8 are uniformly set to one minute.

When the user changes, for example, the lengths tg1 to tg8 of the small amount digest scenes Dg1 to Dg8, the user first presses the push button 24c of the remote controller 24 shown in FIG.
13A shows the reference timing 61 and the initial line 6 shown in FIG.
2 and 63 are displayed. Then, the pointer operation device 24b
, The pointer 59 in FIG.
Is moved to an arbitrary point Q0, and the push button 24c is pressed (clicked) only once to specify the point Q0 on the initial line 63. In this case, the initial line 6 is displayed on the display panel 24a.
It is desirable that the point specified by the user can be visually recognized by increasing the light emission amount of the point specified in 2, 63 or displaying a predetermined mark.

Next, while pressing the push button 24c, the pointer operating device 24b is moved, and the pointer 59 displayed on the display panel 24a is moved (drag) to an arbitrary point Q1.
I do. Then, the point Q0 of the initial lines 62 and 63 moves to the point Q1 to which the pointer 59 moves. As described above, the point Q0 of the linear initial line 63 moves to the new point Q1. At this time, the point Q0 moves to the new point Q1 while maintaining the continuity of the line. As a result, the shape of the linear initial line 63 changes to a curved broken line curve 65. Similarly, any other point on the initial line 63,
An arbitrary point on the other initial line 62 is dragged and moved, and dashed curves 64 and 65 are displayed in the display panel 24a of FIG.
To form The dashed curves 64, 6 thus formed
5, distances tg1 to tg8 in the vertical axis direction from the progress line 61 of the broadcast program are the progress lines 61 of the respective broadcast programs.
This means the length of the small digest scenes Dg1 to Dg8 when the upper point is set as the reference timing. That is, the distance t defined by the upper broken line curve 64 in FIG.
g2, tg4, tg6, and tg8 define the starting point of the small amount of digest scenes Dg2, Dg4, Dg6, and Dg8 immediately before the reference timing (reference symbols T1 to T4 in FIG. 11), and the lower side in FIG. Tg1, tg3, tg5, tg7 defined by the broken line curve 65 of FIG.

The user operates the pointer operation device 24b and the push button 24c.
By clicking and dragging using, the pointer 59 in the display panel 24a can be moved and the lengths tg1 to tg8 of the small-sized digest scenes Dg1 to Dg8 can be easily changed.

Also, a large number of digest scenes Dh1 to Dh1
As for h8, similarly to the small amount digest scenes Dg1 to Dg8 shown in FIG. 13, the pointer 59 in the display panel 24a is moved by clicking and dragging using the pointer operation device 24b and the push button 24c. The timing can be easily changed.

The timing setting operation is performed by the control unit 23 and the digest scene detection unit 41b in the video signal processing unit 41 in FIG. Then, the input signal is transmitted through the control unit 23 to the digest scene detection unit 4.
1b, when the digest is actually reproduced, the digest scene detection unit 41b sets the small amount of digest scene Dg1 in the recording device 46 based on the newly set and inputted instruction values tg1 to tg8 and th1 to th8. ~
Dg8 or a large number of digest scenes Dh1 to Dh8 may be detected, sent to the display device 3, and output and reproduced.

As described above, in this embodiment, the small amount of digest scenes Dg1-Dg1
There is an advantage that the reproduction time of g8 and the large amount of digest scenes Dh1 to Dh8 can be freely changed.

Further, it is possible to change the digest amount only by specifying the time during which viewing is possible by the viewer. That is, if 10 scenes are to be extracted, 1 minute per scene can be prepared for 10 minutes of viewing, but if there is only 1 minute of viewing time, 6 seconds per scene is set to suit the viewer's convenience. It is possible. In this case, the viewer specifies the total digest playback time (digest viewing time) of “10 minutes” or “1 minute”, and calculates the time of each digest scene to obtain “1 minute” or “6 minutes”. Seconds ".

[0129] Furthermore, the 3rd program at the beginning, middle and end of the program
For a scene, 20 seconds may be extracted per scene.

In this embodiment, the digest scenes Dg1 to Dg8 and Dh1 to Dh8 are set based on the reference timings T0 to T4 at regular intervals. For example, in the second embodiment, In this manner, the setting may be made based on the boundary point between the broadcast program video and the CM.
