2. Description of the Related Art In recent years, digital satellite broadcasting has started, and it has become possible to select and receive a desired program from television programs of 100 channels or more which are broadcast at home. In this type of digital hygiene broadcasting, program guide information (a list of titles, genres, broadcasting dates, etc.) is sent in the broadcast radio wave to facilitate the viewer's program selection, and the receiver receives it. Using this, a program guide is displayed so that the viewer can select a program to watch.

FIG. 2 is a diagram showing a transmission state of a broadcast signal. Many programs (programs) are time-divisionally transmitted in the same band as signals of digital satellite broadcasting, and program table information is inserted between these program signals at predetermined intervals. The header distinguishes the program signal from the program guide information. In addition to the video signal and the audio signal, the program signal includes program information associated with the program such as the title and genre of the program and the presence or absence of a violent scene in a predetermined position in a predetermined format.

On the other hand, in a domestic VTR, when a television broadcast is recorded, program information such as channel, recording date and time, genre, cassette number, etc. is stored in a memory built in the VTR main body, and the contents thereof are stored as necessary. Is displayed so that the viewer can search the contents recorded so far. Regarding the cassette number, there are ones in which cassette number information is inserted into a part of the video signal at the time of recording, and a sticker on which a bar code indicating the cassette number is printed is attached to a predetermined position of the cassette.

Since information about the title and genre cannot be obtained automatically in ordinary terrestrial broadcasting, the viewer can select information such as the genre from the list displayed on-screen, or input the title etc. from the keyboard. By doing so, it may be stored in the second memory 303 via the microcomputer 301.

Also in the case of analog video signals, for example, US EIA (Electronic Industries Association) is used.
n) As shown in the standard EIA-608-A, a digital signal is superimposed on a predetermined line of the vertical blanking period, and the title, genre, and rating (whether there is a violent scene of the program) of this digital signal are superimposed. It has been proposed to transmit information associated with the program, such as those classified into ranks by evaluating the suitability of showing to children about the degree and degree). When receiving an analog signal on which such a signal is superimposed, the program information superimposed on a predetermined line in the vertical blanking period may be extracted and stored in the second memory 303.

Further, even when an already recorded medium in which contents such as movies are recorded is obtained on the recording medium, the information of the attribute of the program written at a predetermined position in the recording medium is reproduced and the second information is reproduced.
May be transferred to the memory 303, or may be manually input using a keyboard or the like.

The tape number is set at the time of the first recording on the cassette, and is recorded within the vertical blanking period of the recorded video signal, or the number represented by the bar code affixed to the cassette in advance is used. The number makes it possible to identify the individual cassettes.

The contents stored in the second memory 303 are as follows.
There are tape number, source type, channel, start time, recording time, start position (position on tape), title, genre and the like. First memory 302 and second memory 30
The contents stored in 3 are not limited to those described above, but include, for example, information indicating the aspect ratio of an image (16: 9, 4: 3, etc.) and memo information input by the listener using a keyboard, etc. For memory 303 of VT
Information on the recording mode of R is considered.

As described above, the first memory 302 stores program guide information obtained from digital satellite broadcasting and terrestrial broadcasting, and the second memory 303 stores program information of programs recorded in the VTR. It And the third memory 3
