Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video signal recording / reproducing apparatus, and more particularly to recording and reproducing a television signal and the like and receiving a VBI (vertical blanking interval) broadcast including the television signal. The present invention relates to a control method using VBI data of a video signal recording / reproducing apparatus such as a VTR and its apparatus (VTR).

[0002]

2. Description of the Related Art VBI broadcasting means a so-called VBI program which is broadcast by superimposing additional information of a program on a gap portion where a video signal is actually sent from Vsync.

Conventionally, VBI of a television broadcast signal
In the (vertical blanking period), various signals (programs) are superimposed and various data services are provided. Of which
The most typical and oldest one is a character multiplex broadcasting in which character (mainly character) information is superimposed on the VBI.

The teletext is internationally called Teletext, and was developed in England around 1972.
If television means "see distant things,"
Teletext means "reading distant things".

In Europe, the teletext called teletext has been available since 1976 in the British broadcasting station BBC.
Broadcast started by. The original purpose of teletext was started for the hearing impaired, but in recent years, information for the general public has been enriched, and various information such as weather forecasts, news, and traffic information has come to be provided. ing.

The teletext system in Japan was also developed at about the same time as the British teletext, but it was devised because of the peculiarity of Japanese (Kanji).
A test broadcast was started in 983, and N was released in November 1986.
The main broadcasting has started from HK and NTV.

[0007] Furthermore, the character multiplex broadcasting in the United States is 1
From March 980, ABC, NBC and PBS (Publi
c Broadcasting Service: Broadcasting is started by the US public broadcasting service.

By the way, the character multiplex broadcasting in the United States,
It is called closed captioning and is mainly broadcast for people with hearing loss. In recent years, all the programs of prime time (time zone with a high audience rating at night) provided by the three major networks (CBS, ABC, NBC) are broadcast with captions. Moreover, these are not limited to TV programs, but are expanding to package media such as video software and video discs, and cable TV.

On the other hand, FIG. 5 shows the first and second NTSC systems.
During VBI (vertical blanking interval) in the field,
The vertical sync signal period and the equalization pulse periods before and after it are
It is the figure which expanded and showed.

As can be seen from the figure, VBI in the first field consists of 21H (line), and 1H (line) to 9H (line) of VBI in the first field is divided into 3H every 3H. ~ 3H pre-equalization pulse period 41,4H ~ 6H vertical sync pulse 42,7
It is composed of a post-equalization pulse period 43 of H to 9H. Therefore, in the character multiplex broadcasting, data is transmitted using a period other than the above, that is, several horizontal periods of 10H to 21H in the first field and 273H to 284H in the second field.

FIG. 6 shows the first and second NTSC systems.
In the VBI in the field, 14H to 21H and 277 which are horizontal periods in which the character information data is superimposed.
It is the figure which expanded and showed H-284H.

In the figure, the television video signal 31 is inserted in the periods other than VBI (horizontal period) except the horizontal blanking period. In the closed caption system which is the character multiplex broadcasting in the United States, the horizontal period 3 in the VBI of the first field shown in FIG.
The character information data is superimposed on 5 (21H).
On the other hand, in teletext, which is teletext in Japan,
Horizontal periods 32 to 39 in the VBI of the first field shown in (a) and the second field shown in (b) of FIG.
(14H, 15H, 16H, 21H, 277H, 278
H, 279 and 284H), the character information data is superimposed. It should be noted that the reason why Japanese text broadcasting has more text information data superimposing areas than the US closed caption system is because the data volume is large because it contains complicated characters such as Chinese characters.

[0013] Next, another example of the one in which the data service is provided by superimposing the signal on the VBI of the television broadcasting signal, that is, the secret broadcasting is made available only to the residential units of each contractor, CATV. A brief description of the (cable TV) secret broadcasting system will be given.

FIG. 7 is a diagram showing the principle of the video scramble system. FIG. 8 is a diagram showing a pay satellite broadcasting system.

Generally, in a commercial satellite broadcasting station, in order to prevent anyone other than the contractor from receiving the broadcasting, COAT
Scrambled broadcasting is being carried out by the EC (Conditional Access Technoloqy Research Laboratory) system and the like. This is, for example, for an image without scramble as shown in FIG. 7A, cut points are provided in the scanning line as shown in FIG. 7B, and the left and right are interchanged (line permutation method). As shown in FIG. 7C, the positions of the images are exchanged (line rotation system) to broadcast in a state where viewing is impossible without a decoder. The contractor can restore the original video / audio using the decoder and view it.

On the other hand, in FIG. 8, a transmitter (broadcasting station) 1
The BS broadcast radio wave transmitted from 00 is received by the BS antenna 2 for joint reception via BS1, and is sent to the headend 3 as a BS-IF signal. The headend 3 performs FM detection by the BS tuner, separates the scrambled video signal from the BS 1 and the bit stream, and further separates the information signal and the related information packet (program information etc.) for descrambling from the bit stream. Then, after the information signal for descrambling is packetized and time-division multiplexed with the related information packet, the horizontal period in the VBI of the first field shown in FIG. 6A of the scrambled video signal. 51, 52 (17
H, 19H) and horizontal periods 53, 54 (280H, 282) during VBI of the second field shown in FIG. 6B.
HBI), and the VBI-multiplexed scrambled video signal and the descrambled signal of the scrambled audio signal are respectively re-modulated (AM-modulated), frequency-multiplexed and transmitted to the cable 4.

The cable 4 is provided with a decoding device (hereinafter, referred to as VBI) corresponding to a plurality of VBI multiplexing of each user.
A corresponding decoder) 5 is connected. Also, VB
The I decoder 5 performs AM detection by the VHF / UHF tuner, separates the scrambled video signal and the audio signal, further separates the packet multiplexed in the VBI of the scrambled video signal, and then demultiplexes the separated packets. The scrambled video signal is descrambled based on the information packet for scrambling. And
The descrambled video signal is demodulated and output by a television receiver or the like (not shown).

The above is a typical example in which a data service is performed by superimposing a signal (program) on the VBI of a television broadcast signal.

By the way, in a conventional VTR capable of receiving VBI broadcast, the contents of the VBI broadcast are recorded on a tape or stored in a memory, the contents of this VBI broadcast are taken out at the time of reproduction, and the VTR is based on these contents. It would be very convenient to have a VTR that controls the operation of the VTR at the time of reproduction, as well as a reservation setting operation (currently none exists).

Currently, in order to correctly execute the recording reservation,
There is a VTR having a function of superimposing a signal containing a program code of a program currently being broadcast on the VBI and recording the program while the program code and the program code designated by the recording reservation match. However, this is because the user judges from the program contents and the user sets and controls the operation of the VTR.
This is different from the one in which a signal for controlling the operation of the VTR at the time of reproducing the VTR is superimposed on the BI and the VTR makes a judgment based on the data and controls itself.

Generally, television broadcast programs often contain redundant content. That is, since a common program is broadcast to an unspecified number of viewers (hereinafter, also referred to as users), one program may include a lot of unnecessary information. Will be there. Further, when the time to watch the program is restricted (such as when the user is busy), it is convenient if only the main part of the program can be viewed by cutting other less important information (part) in the program. However, the conventional VTR does not have a function of cutting an unnecessary portion (or a portion that is not so important) of the program as described above. Therefore, V
The following inconveniences have arisen for viewers watching programs recorded in TR and the like. That is, (1) When viewing a playback video of a VTR, when the viewer wants to skip a scene that he / she does not want to see, such as during soccer half time or basketball timeout, Since we don't know where the match will be restarted, we have to keep looking at the fast-forward playback screen to find the position where the match will restart. (2) The VTR originally has a time compression function, which is generally realized by editing the recorded video. On the other hand, if such an editing operation is to be performed by an individual each time, a lot of time is required for this editing. Therefore, if you try to shorten the recorded program (video) by a method other than editing, you should continue to view the fast-forward playback screen and skip unnecessary playback parts as in (1) above. You have to shorten the playback time with. (3) If the viewing time is limited and you want to watch only the main points (important parts) of the program (video) within a predetermined time,
Which part to play and which part to skip (fast forward)
I don't know if it's good. If you really want to watch the important points (important parts), you must follow the same method as (1) or (2) above. (4) For a program that is broadcasted continuously (periodically) such as a drama or one that is completed in one episode, do not make a timer reservation next time unless you finish watching the program or watch the next trailer. I don't know whether to do it or not. Also, when I want to see it next time, I often forget to set timer reservation at a later date unless I make a timer reservation on the spot. That is, it is convenient if the next timer reservation setting for the program is easily (automatically) performed at the end of the program reproduction.

[0022]

As described above, various control contents of the VTR, etc., which are currently performed by superimposing a signal on the VBI of the television broadcast signal, are used to control the operation of the VTR during the VTR reproduction. A service provided by superimposing data for performing a reservation setting operation or the like on the VBI is not currently provided. Therefore, when viewing a program recorded by the VTR, the program is only continuously played back, and the time shift function of the VTR, that is, the function of watching the program while shortening the playback time is sufficient. There was a problem that it was not utilized.

Therefore, in order to solve such a problem, the present invention enables not only the continuous reproduction but also the time shift function of the VTR when watching the program recorded by the VTR.

For example, during the recording of the program, the detailed program content information is accumulated in the internal memory of the control circuit 14, etc., and when the recording of the program is completed, a detailed program information list is created from the accumulated data, The program detailed information list or the plurality of accumulated data is recorded on the recording medium 11 by the VASS system or stored in an external memory such as the program information memory 15 and the program detailed information list is read at the time of reproduction, or It is possible to obtain the detailed program information list by creating the detailed program information list from the accumulated data.

Further, the broadcasting station transmits important scene rank information as the detailed program content information (list of detailed program information), so that the viewer can select only the desired scene from the desired programs. It is possible to watch the program in a shorter time.

By the way, according to the embodiment of the present invention, the control information for controlling the VTR is acquired (Oh,
There are two methods as the method of (I broadcast data), that is, VBI broadcast data and VASS signal.

FIG. 3 is a flow chart showing an example of a criterion for judging which of VBI broadcast data and VASS signal is used for VTR control.

According to an exemplary embodiment of the present invention, FIG.
As shown in (a), writing to the recording medium 11 is performed. That is, the control circuit 14 first reads the VBI broadcast data (step s1), determines whether or not the content of the VBI broadcast data has changed (step s2), and if there is no change, the above step is performed. The operation of s1 is repeated. When the content of the VBI broadcast data is changed, the VASS signal is embedded in the storage medium 11 (step s
3). At this time, the content of the VBI broadcast data may be inserted in the address portion of the VASS signal, and then the VASS signal may be embedded.

Then, it is judged whether or not the program has ended (step s4). If the program has not ended, the process returns to step s1 to repeat the above process. On the other hand, when the program ends, the VASS signal (and VB
The writing of the I broadcast data) is completed.

Next, as shown in FIG. 3B, when reading the VASS signal (and VBI broadcast data) from the recording medium 11, for example, the setting of the VTR playback mode from the operation key 16 is set to the low speed CUE / In the case of REV or normal reproduction, control of the VTR is performed based on the VBI data (steps t1 and t2), and the setting of the reproduction mode of the VTR from the operation key 16 is set to the high speed CUE / REV or FF / R.
In the case of EW, the VTR is controlled based on the VASS signal (steps t1 and t3).

When the VTR control is performed as shown in FIG. 3B, for example, when the VTR playback mode is set to the high speed CUE / REV mode or the FF / REW mode, only the VASS signal is sent. If a VASS signal is detected (changes in detailed information of the program content are detected), the speed is reduced to the low-speed CUE / REV mode, or rewinding and playing back the VBI recorded directly on the tape. The signal is detected and VTR control is performed.

Further, in FIG. 3A, when the VASS signal is input to the recording medium 11, the VASS signal is input after the content of the VBI broadcast data is inserted in the address portion of the VASS signal. The VTR playback mode is set to high-speed CUE / REV mode or FF / R.
In EW mode, when VASS signal is detected, it is possible to detect VBI signal directly from VASS signal and perform VTR control by reading the content of VBI broadcast data inserted in the address part of VASS signal. Is.

As described above, according to the present embodiment, the unnecessary portion in the program for the viewer is VASS.
It is possible to skip using the information obtained from either the signal or the VBI signal. That is, when the viewer sets a selection key, the control circuit 14 automatically skips unnecessary playback portions by fast-forwarding or fast-forwarding playback based on the program detailed information list, and shortens playback time (semi-automatic playback). (Reduction of time) is possible.

Further, at this time, as the program broadcast by the broadcasting station and the detailed content information of the program, for example, the following are listed. That is, in addition to the contents of (a) to (e) above, (f) content information in news programs (for example, sports news, economic news, political news, weather forecasts, etc.) (ki) Individual players in golf programs, etc. Information, etc. for each (h) Important scene rank information, etc. (Priority is given to the scenes that the broadcaster wants the viewer to see, and this is used by the viewer as a reference to see where and where they do not see) And so on. Then, the VTR control described above is performed based on these pieces of information.

Furthermore, according to the embodiment of the present invention, the following operation can be performed in addition to the contents already described.

That is, the broadcasting station transmits a list of detailed program information by VBI broadcasting and broadcast time for each program content as detailed program content information at the beginning of each program. Using this, a detailed information list of program contents is created, and from this, the part that the user has designated (selected) by prioritizing (or the stored data of the selection information that the user has made in the past) and the ) With reference to important scene rank information, etc., automatic calculation (setting) is performed so that the playback is completed within the time specified by the user, and only the selected portion is played back in the standard mode. The portion can be fast-forwarded or fast-forwarded and played back so that the program can be viewed (played) within a time designated by the user. If the automatic calculation does not fit within the user's desired time, the user specifies (selects) from the detailed information list of the program contents, and performs standard playback only on the specified part. Short playback is performed.

Further, in the case where the automatically edited program does not fit well within the time specified by the user, the result time automatically calculated may be displayed in the detailed information list so that the user can correct it. . When the program detailed information list and the broadcast time for each program content are not known at the beginning of the program, time data is added to the program content detailed information during recording of the program to add an internal memory of the control circuit 14 or a program information memory. 15, the detailed program information list is created from the accumulated data at the time when the recording of the program is finished, and the broadcast time of each program content is also the VBI transmitted by the broadcasting station at the end of the program.
Get by broadcasting.

As described above, according to the above-described embodiment, unnecessary portions of the program are skipped by fast-forward reproduction or fast-forward, so that the program is automatically reproduced within the time specified by the user. Can be completed.
