Receiving device, delay-information transmitting method in receiving device, audio output device, and delay-control method in audio output device
A television receiver computes a delay time of an image displayed on the television receiver with respect to an audio signal transmitted from the television receiver to an audio amplifier, based on video delay information as EDID data, delay information transported from a disc recorder and information of a time required until audio data received from the disc recorder is transmitted to an audio amplifier. The audio amplifier controls a delay time lasting until the audio responsive to the received audio data is outputted so that the delay time matches the aforementioned delay time. Thereby, the displayed image in the television receiver and the audio output in the audio amplifier are synchronized.
