Abstract
An audio device (e.g. an AV amplifier), with a plurality of audio output terminals according to the HDMI standard, converts audio data of a source device into audio signals suited to audio reproduction abilities (e.g. channel counts) of sink devices. The audio device stores a plurality of audio reproduction ability information describing the predetermined channel count thereof and the channel counts of sink devices, wherein arbitrary audio reproduction ability information precluding audio reproduction ability information of a sink device with the smallest channel count is provided to a source device. The audio device performs down-mixing on audio signals with respect to a sink device whose channel count is smaller than the predetermined channel count, while the audio device performs signal processing on audio signals with respect to a sink device whose channel count is larger than the predetermined channel count.
