摘要：
In an audiovisual system in which a source device and a television are connected via an AV amplifier, even when the AV amplifier is placed in a “Power Supply Standby State”, video/audio signals outputted from the source device can be viewed/listened to on the television without changing the wiring connections between the devices.An AV amplifier (100) is provided with a data storing means (106) used for indicating a signal reproduction ability to a source device (200). During a “Power Supply Standby State” of the AV amplifier (100), the content of data that is saved in the data storing means (106) and indicates an audio signal reproduction ability is rewritten into data that indicates not the reproduction ability of the AV amplifier (100), but the signal reproduction ability of a television (300), thereby producing a state that is equivalent to a state in which the source device (200) and the television (300) are directly connected.
