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.
Claims7
An audio output device comprising:
- a first and a second connection terminal;
- a first and a second storage unit corresponding to the first and second connection terminals, respectively, and configured to pre-store audio output performance information of the audio output device;
- and
- a control unit configured to acquire the audio output performance information of an audio system connected to the first connection terminal, and perform control to rewrite the audio output performance information stored in the second storage unit to match the acquired audio output performance information of the audio system.
A method of controlling an audio output device including a first and a second connection terminal, and a first and a second storage unit corresponding to the first and second connection terminals, respectively, and configured to pre-store audio output performance information of the audio output device, the method comprising the steps of:
- acquiring audio output performance information of an audio system from the audio system via the first connection terminal when the audio system is connected to the first connection terminal, and
- performing control to rewrite the audio output performance information stored in the second storage unit to the acquired audio output performance information of the audio system.
