And set the timer time, for example, 90 minutes in 30 minute increments.
It is possible to set up to the minute, and by pressing the sleeve key (671) while the time is displayed, the timer time is set according to the number of times the sleeve key (671) is pressed. When the timer time is set, the personal computer (65) determines whether the difference between the time at the time of setting and the current time data transmitted from the central controller (1) corresponds to the timer time. This determination operation is performed every time time data is supplied, and when the timer time comes, the monitor receiver (63) is powered off.

For example, when the sleeve timer time is set to 60 minutes by the above operation, the memo U (65a) stores the time when it was set, and checks whether the difference between this stored time and the current time is 60 minutes. The personal computer (65) makes this determination and controls the power to be turned off when 60 minutes have elapsed. If a passenger wants to watch the video signal channel again when the scoop timer function is activated and the power is turned off, for example, by pressing the enter key (67g), the power is turned off using the sleeve timer function. (in other words, turn on the power).

It is easy to use and allows you to turn off the monitor. In addition, each terminal device (6a), (6b), (
Since the 6c) side does not have a clock function, the configuration becomes simpler, and all terminal groups W (6a), (6b) can be set by synchronizing the time only on the central control unit (1) side.
, (6'c)... The time displayed is accurate, and there is an advantage that the crew can easily manage their clocks.

In addition to the sleeve timer function, a timer function may be provided to automatically turn on the monitor receiver (63) when a set time has elapsed, so as to operate as a so-called alarm clock. In this case, press the wake-up key (67m) a predetermined number of times while the time is displayed to select the time until you wake up, and the timer function determines whether this time has elapsed or not, and when it has elapsed, the power is automatically turned on. to start receiving a predetermined video channel.

Furthermore, the on/off control of the audio played through the headphones (68) connected to the terminal side controller (66) may be performed simultaneously (or separately) with the on/off control of the monitor receiver (63). good.

Further, in the above embodiment, each terminal device (6a).
