发明名称 SOUND REPRODUCING APPARATUS AND AUDIOVISUAL SYSTEM
摘要 <p>In an audiovisual system having a source device and a television set connected thereto 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 on the television set without changing the connection between the devices. An AV amplifier (100) has a data storing means (106) used for notifying a source device (200) of a signal reproduction ability. During a "Power Supply Standby State" of the AV amplifier (100), the content of the data, which is stored in the data storing means (106) and indicative of the audio signal reproduction ability, is rewritten into a data not indicative of the reproduction ability of the AV amplifier (100) but indicative of the signal reproduction ability of a television set (300), thereby realizing a state that is equivalent to the fact that the source device (200) is connected directly to the television set (300).</p>
