AUDIO OUTPUT SYSTEM CONTROL METHOD AND AUDIO OUTPUT SYSTEM

摘要

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 (403) of a DVD player (400) transmits a request signal concerning the audio output mode to a control unit (105) of a TV (100). According to a request from the DVD player (400), the control unit (105) of the TV (100) instructs a control unit (203) of an AV amplifier (200) to be set to a mode for outputting audio from an external speaker (300) connected to the AV amplifier (200) or a mode for not outputting audio and sets a built-in speaker (110) of the TV (100) to a state opposite to the state of the external speaker.
