Abstract:
1. A device control system for controlling an operation of a first information processing device mounted on a mobile apparatus, the first information processing device having a function to receive data, broadcast at low speed or high speed from an information center, through a low-speed broadcast channel or a high-speed broadcast channel and being switched between an ON state and an OFF state normally in response to switching of the mobile apparatus between an ON state and an OFF state, the device control system comprising: a first processing section to recognize whether the first information processing device is set to receive data through the high-speed broadcast channel; and a second processing section, when the mobile apparatus is switched from the ON state to the OFF state, to maintain the first information processing device in the ON state and cause the first information processing device to receive designated data through the high-speed broadcast channel on the condition that it is recognized by the first processing section that the first information processing device is set to receive data through the high-speed broadcast channel, wherein when it is recognized by the first processing section that reception of the designated data through the high-speed broadcast channel by the first information processing device has been interrupted, the second processing section switches the first information processing device from the ON state to the OFF state on the conditions that the mobile apparatus is in the OFF state and that an amount of an unreceived portion of the designated data is equal to or eater than a threshold value and the second processing section maintains the first information processing device in the ON state and causes the first information processing device to receive the unreceived portion of the designated data through the low-speed broadcast channel on the condition that the amount of the unreceived portion of the designated data is less than the threshold value.
