Description of operation during G3 operation Next, operation when the system of this example is used during flight of an airplane will be explained.

First, at the start of each flight of this airplane, the crew operates the keyboard (20) of the central control unit (1), etc.
Power on the entire system. For example, as shown in FIG. 4, the power is turned on at point a while the airplane is landing at the airport. At this time, the mask controller (19) detects that the power-on detection signal has changed from the low level signal "0" to the high level signal "1".

Then, when the power of the system is turned on, that is, the power-on detection signal becomes a high level signal "1", the mask controller (19) controls each VTR (11), (12) connected to the system controller (10). ), (13
), (14) and the audio players (25) and (26), all video tapes and music tapes installed in the tape playback devices are rewound to the beginning. When the rewinding is completed, the tape is stopped running and placed on standby with the tape rewound to the starting end.

In this way, according to the system of this example, when the system is powered on, all video tapes and music tapes are automatically rewound to the beginning, so that all VTRs (11) to (14) and music player (
25) The video tape and music tape loaded in the tape playback device of (26) are rewound to the beginning.

Therefore, even if the crew does not have to rewind the tape, video programs such as movies and music, and music programs will always be played from the beginning, saving the crew the trouble of rewinding the tape, and allowing each passenger to Since you can always watch movies, music, etc. from the beginning, serviceability is improved.

In the above embodiment, a system was described in which a video signal was supplied to a receiver provided for each passenger seat.
For example, if a large video projector device is installed in each zone of the aircraft, and multiple passengers view the video program displayed by the projector device, the tape rewind of the VTR used to transmit the video program is performed when the system is turned on. You may also do so. Furthermore, in the above embodiments, the present invention was applied to an airplane, but it goes without saying that the present invention can also be similarly applied to other vehicles such as trains and buses.

Furthermore, it goes without saying that the present invention is not limited to the above-described embodiments, and can take various other configurations without departing from the gist of the present invention.

H Effects of the Invention According to the present invention, the video tape and music tape loaded in the VTR and tape playback device are automatically rewound when the system is powered on, so that the video program and music program are always played from the beginning at the start of operation. This has the advantage of improving service to passengers and saving the crew the trouble of rewinding the film.
