摘要： 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 device 1 serves as a master, and distributes the audio channels to be processed to the other AV amplifier devices 1 including the own device 1, and determines, on the basis of the signal processing time of each AV amplifier device 1, the output delay time of each AV amplifier device 1 such that the output timings of the analog audio signals of all AV amplifier devices 1 match each other. Then, the AV amplifier device 1 decodes the input digital audio signal into an analog audio signal for an audio channel distributed to the own device 1 by the master, and delays and outputs the decoded analog audio signal by the output delay time of the own device 1 determined by the master.

摘要： [Problem] To provide a network AV receiver device capable of preventing the suspension of the playback of music when the music can no longer be inputted from a media server that is inputting the music, the network AV receiver device playing back the music inputted from the media server, which is connected via a network and accumulates music. [Solution] A network AV receiver device is provided with a music information storage unit for storing the music information of the music recorded in each media server connected to a network, an input state detecting unit for detecting the input state of a media server which inputs the music currently being played back, and a control unit, wherein when the input state detecting unit detects that the input state of the music data currently being played back is not normal, a media server of the music data currently being played back is switched to music data recorded by another media server on the basis of the music information of the music recorded in the media server stored in the music information storage unit.
