Abstract
In a television device (audio output device), audio output performance information of the television device is pre-stored in an EDID-ROM. When an AV amplifier is connected to the television device, a control unit rewrites '2ch' audio output performance information of the television device stored in the EDID-ROM of an HDMI port which is different from the HDMI port to which the AV amplifier is connected, to '5.1ch' audio output performance information of the AV amplifier.
