Abstract:
In an audio output system including a TV, an AV amplifier, a DVD player, and the like, a simple control program decides an audio output mode setting, i.e., whether to output audio from a built-in speaker of the TV or output audio from an external speaker connected to the AV amplifier by linking operations of the respective devices. A control unit of a DVD player transmits a request signal concerning the audio output mode to a control unit of a TV. According to a request from the DVD player, the control unit of the TV instructs a control unit of an AV amplifier to be set to a mode for outputting audio from an external speaker connected to the AV amplifier or a mode for not outputting audio and sets a built-in speaker of the TV to a state opposite to the state of the external speaker.
