Abstract
When the main power supply is turned off, the power supply of a video display unit is turned off and the audio signal is muted. At the same time, a time counting unit counts time, and before reaching a predetermined time, a display unit is lighted to notify a quick restart period. In the case where the main power supply is turned on during the predetermined time, the power supply of the video display unit is turned on to cancel the audio mute mode. In the case where the main power is not turned on upon lapse of the predetermined time, the power supply of the receiving unit is also turned off.
