[Conventional technology]

Conventionally, in a broadcasting station, for example, when broadcasting a news program, a news program, etc., a relay video from each relay station,
For playing back a studio video from a TV camera in a studio that captures the facilitator (moderator, announcer, caster, etc.) of the news program, and a video cassette tape (transmission tape) on which pre-edited video and the like are recorded. The playback video from the VTR (for example, there is a video related to the news) is supplied to the transmission control console, and the supplied video is switched by the transmission control console, and then supplied to the transmission device and broadcast. .

The transmission tape to be reproduced by the reproduction VTR is, for example, a material tape on which a video taken before the broadcast of the program (for example, an interview, a relay, etc.) is recorded and edited according to the program to be broadcast. After the material tape is used in the production operation of the transmission tape, and after the transmission tape is used in the program, the identification tapes are respectively attached and stored in, for example, a warehouse. Hundreds of thousands of material tapes and output tapes are stored in this way in several years.

The identification tag affixed to each of the material tape and the transmission tape includes a code number or program data such as a program name (title), a broadcast date, a broadcast start / end time, and the like for which the material tape and the transmission tape are to be used. The code number and program data are recorded in a storage device via a computer. This is for searching for a material tape used for the program to be used in order to use a video of a previously broadcasted program related to a program to be broadcasted next.

Next, a description will be given of a case where a material tape used in a program broadcast in the past is used at a stage of producing a transmission tape of a program scheduled to be broadcast.

For example, when broadcasting a special program on the theme of a certain person, as a configuration of the program, for example, in a studio of a broadcasting station, a talk between the moderator and the person is broadcasted as a so-called live broadcast, and the past related to the person is broadcasted. It often broadcasts video and the like.

In the above-mentioned program, the times at which the live broadcast video and the reproduced video from the VTR are broadcast are each demarcated within the time frame of the program. Therefore, the reproduced video must be recorded on the transmission tape in accordance with the program. To make such a transmission tape, examine past cases and the like related to the person, and broadcast date and name of the person (material title) up to several days after the date when the case occurred. Is entered into the computer to search. The code number and the program data corresponding to the input information are displayed on, for example, a monitor screen of a computer, and the displayed code number or the material tape on which the identification tag with the program data is written is stored. Search all the places and play the found material tape. Then, only the video necessary for the transmission tape to be produced is edited and produced from the found material tape.

[Problems to be solved by the invention]

As is evident from the above, when broadcasting a video taken in the past in a certain program, all the material tapes with the identification tags obtained by searching with a computer are retrieved from the material tape storage location and taken out. After that, all the found tapes are played back to find the tape on which the necessary video is recorded, and further edited from the tape to produce a transmission tape, so the necessary video is recorded. It takes a lot of time to find a tape. Therefore, during that time, others cannot use the large number of tapes taken out.

Also, since many tapes are taken out of the storage area at once, tapes cannot be returned to the storage area,
Tapes often break. Therefore, it is very difficult to maintain the quality of the material tape stored in the storage place and the reliability as data.

In view of such a point, the present invention provides a storage video recording medium on which a desired storage video signal is recorded from a large number of storage video recording media on which respective storage video signals are recorded, in a simple and short time. Another object of the present invention is to propose a library search device for a storage video recording medium that can be reliably searched.
