用不具AV端子的电视机接收AV设备播放的节目,要想获得高质量的图像效果,就要为该种类型电视机加装AV端子。彩电加装AV端子后一般是用外加一只手动开关来控制其AV/TV功能的切换。早期生产的不具AV端子的遥控彩电,其遥控系统CPU大都具有AV功能,只是因为该电视没有AV端子而未被利用。只要对CPU中的有关电路稍加改动并对所加装的AV端子增加一接口电路,便能实现该彩电AV/TV转换功能的本机键控和手机遥控控制,省去了手动开关,操作使用更为方便。长虹CK53A彩电CPU增加AV功能的方法如下:
To receive a program played by an AV device with a TV without an AV terminal, add an AV terminal for that type of TV for high-quality video. After the installation of color TV AV terminal is usually used plus a manual switch to control its AV / TV function switch. Earlier production of remote control TV without AV terminal, the remote control system CPU mostly has AV function, just because the TV without AV terminal but not being used. As long as the circuit in the CPU a little change and added to the AV terminal to add an interface circuit, you can achieve the color TV AV / TV conversion function of the local keying and mobile phone remote control, eliminating the need for manual switching, operation Use more convenient. Changhong CK53A color TV CPU to increase the AV function as follows:
