Abstract
When a changeover instruction is input to video output changeover control section 108, power control section 112 turns on the power to changeover target video output section 102. Timing change section 111 synchronizes sync signal Y output by changeover target video output section 102 with sync signal X output by changeover source video output section 101. Power control section 112 turns off the power to changeover source video output section 101.
