Will be automatically recorded. In this case, the internal operation is to detect (search) a program corresponding to the time and channel of the program reserved for recording from the TV broadcast program being broadcast, and superimpose it on the detected broadcast program or TV broadcast signal. The transmitted identifier is detected, and the program with the matched identifier (for example, 12345) is automatically recorded on another recording device.

By the above operation, the moving image can be provided to the viewer as the information about the program contents easily and inexpensively with a simple structure by using the information transmission medium such as the existing television broadcasting network. Therefore, it is possible for the viewer to easily understand the content of the program and to provide sufficient program information to the viewer.

In the video search device according to the above embodiment, the "program digest" as shown in FIG.
The information including the program name of this program and its broadcast channel and broadcast time, or the information including the "program digest" and the program name of this program and its identifier, as shown in FIG. The information is supplied by an information recording medium and is stored in the storage section 8a in the control means 8 via the information input means 3. However, the above "program digest", the program name of this program, its broadcast channel and broadcast. As shown in FIG. 5, the information consisting of time, or the information including the “program digest” and the program name and its identifier of this program is transmitted from the antenna A1 by the television signal transmitted by the television broadcasting radio wave and superposed on the teletext. The information separating means receives information from the information contained in the transmission data of the teletext which is received via the television broadcasting receiving means 1 and is superimposed on the television signal.

In the video search device shown in FIG. 5, for example, the "program digest" is recorded and reproduced by the video recording / reproducing means 2.
When recording is to be performed on, the program name, channel, broadcast time, and digest program identifier are included as various program information from the teletext data sent in advance by teletext as shown in FIG. After the information is separated by the information separation means 12, it is stored in the storage section 8a as a program guide tabulated based on the information via the information input means 3, and thereafter, as described above. When the digest program corresponding to the program guide transmitted in advance by text broadcasting is broadcast, the identifier added to the broadcast signal of the digest program is separated by the identifier separating means 13, and the identifier is stored in the storage unit. If it is in the identifier in the program table stored in 8a, the video of the digest program currently being broadcast is automatically recorded in the video recording / playback means 2. It can also be configured.

The program guide stored in the storage section 8a can be displayed on the video presenting means 6 through the information visualizing means 4 if necessary. In this way, when an identifier is associated with the video of a program (here, a digest program) to be recorded in the video recording / playback means 2, the program guides sent in advance are sent together for about one week. Since the broadcast time is usually changed, the broadcast time of the program may be changed. Can be increased. In other words, even if the broadcast time slot is shifted due to the convenience of the broadcaster (interruption of a special program or the like), it is possible to prevent the viewer from recording an incorrect program.

Also, from 6 to 3 days before the broadcast date of this program, a short digest program is broadcast with an identifier, and the detailed digest program corresponding to the digest program is the same as the day before the broadcast of this program. By broadcasting with an identifier, the viewer can see the short digest program for the same program up to the day before, just by recognizing the identifier, and see the detailed digest program on the broadcast day. be able to. That is, the broadcaster side can arbitrarily decide the broadcast time and broadcast.

As described above, for example, a detailed digest program is desired as information for deciding whether or not to watch the main program for today's broadcast. However, such a detailed digest program is available for one week before the day before the broadcast date. If it is recorded, the storage capacity of the video recording / playback means 2 becomes very large. However, as described above, the detail level of the digest program is switched and broadcast depending on how many days before the broadcast date of this program. Therefore, the storage capacity of the video recording / playback means 2 can be suppressed to a necessary minimum, and the above-mentioned storage capacity problem can be solved.
