Patent ID: 8451388

Claim:
An audio processing apparatus comprising: a transmission signal input/output unit that inputs or outputs a video signal, an audio signal, and a control signal; a reproduction processing unit that reproduces the audio signal inputted to the transmission signal input/output unit or an audio signal inputted to any other audio signal input unit; an output unit that outputs the audio signal, which is processed by the reproduction processing unit, through a loudspeaker; and a control unit that when detecting that a control signal signifying that a predetermined mode concerning the display image quality represented by the video signal should be designated is inputted to the transmission signal input/output unit, controls (i) changing to an audio reproduction mode for audio outputting for the apparatus, so that sounds represented by an audio signal from other apparatus will be outputted from the output unit and the apparatus is in a muting state in which audio output is not outputted from the apparatus, and (ii) transmission to the other apparatus of a control signal with which the sounds represented by the audio signal and outputted through a loudspeaker of the other apparatus are muted, and instructs the reproduction processing unit to perform predetermined sound-field processing or sound-quality processing during the reproduction.
