Ｖ位置に切り換えるようにしたこと、 を特徴とするＡＶシステム。[Scope of Claim for Utility Model Registration] (1) A CDV player that outputs a PLAY signal at the start of PLAY, and an AV amplifier that inputs video and audio signals from an external source including the CDV player, and selectively selects and outputs each. This AV amplifier has a video switching means for selectively outputting one of two or more systems of video signals;
Audio switching means for selectively selecting and outputting one of the audio signals of more than one system, and video switching means and audio switching means based on an input designation signal from the input designation means or a PLAY signal from the outside. In the AV system, the CDV player has a disc discrimination means that discriminates whether the disc is a CD or a CDV and outputs a discrimination signal to the AV amplifier, When the PLAY signal is input from the CDV player, the switching control means switches only the audio switching means to the CDV position when the disc discrimination signal is CD, and switches both the video switching means and the audio switching means to the CDV position when the disc discrimination signal indicates CDV. An AV system characterized by the following. (2) This AV amplifier has a CDV player that outputs a PLAY signal at the start of PLAY, and an AV amplifier that inputs a video signal and an audio signal from an external source including the CDV player, and selectively selects and outputs each of them. 2. Video switching means for selectively selecting and outputting one video signal from two or more systems;
Audio switching means for selectively selecting and outputting one of the audio signals of more than one system, and video switching means and audio switching means based on an input designation signal from the input designation means or a PLAY signal from the outside. In an AV system, the AV system includes a switching control means for controlling switching to a corresponding position, wherein the AV amplifier is provided with a video signal detection means for detecting the presence or absence of a video signal from a CDV player, and the switching control means receives a PLAY signal from the CDV player. When the video signal detection means does not detect a video signal, only the audio switching means switches to the CDV position.
When the video signal detection means detects a video signal, both the video switching means and the audio switching means
An AV system characterized by: switching to the V position.
