Abstract
To enable listening with a desired number of channels at a lower cost and without wasting resources. According to the present invention, a multi-channel digital audio signal is processed through the cooperation of a plurality of AV amplifier devices. One AV amplifier deviceserves as a master, and distributes the audio channels to be processed to the other AV amplifier devicesincluding the own device, and determines, on the basis of the signal processing time of each AV amplifier device, the output delay time of each AV amplifier devicesuch that the output timings of the analog audio signals of all AV amplifier devicesmatch each other. Then, the AV amplifier devicedecodes the input digital audio signal into an analog audio signal for an audio channel distributed to the own deviceby the master, and delays and outputs the decoded analog audio signal by the output delay time of the own devicedetermined by the master.
