If the TV is playing a TV program, the TV will automatically switch from the current playback mode to the HDMI playback mode. When the external input signal is removed, the TV will automatically switch from HDMI mode to TV program mode.
具体的,各种信号输入插座为自动转换模式。例如:先接入HDMI信号,此各种信号输入转换控制及CEC控制信号输出模块只认可HDMI输入信号,HDMI信号经HDMI开关模块中转后直接输出(在无5V供电的情况下,只有HDMI输入信号有效,其它输入信号无效),当再接入VGA及双声道信号时,通过各种信号输入转换控制及CEC控制信号输出模块将HDMI信号屏蔽,此时各种信号输入转换控制及CEC控制信号输出模块只认可VGA及双声道信号输入有效,又接入AV信号时,通过各种信号输入转换控制及CEC控制信号输出模块将HDMI信号和VGA及双声道信号都被屏蔽,此时各种信号输入转换控制及CEC控制信号输出模块只认可AV信号输入有效。又接入USB信号时,通过各种信号输入转换控制及CEC控制信号输出模块将HDMI信号和AV、VGA及双声道信号都被屏蔽,此时各种信号输入转换控制及CEC控制信号输出模块只认可USB信号输入有效。此时如果需要VGA及双声道信号时,只要将AV、USB信号接入拔出,则各种信号输入转换控制及CEC控制信号输出模块自动认可VGA及双声道信号输入有效。即在每次使用过程中,各种信号输入转换控制及CEC控制信号输出模块自动记录该次各种信号接入的顺序。 Specifically, various signal input sockets are in an automatic conversion mode. For example: first connect to the HDMI signal, the various signal input conversion control and CEC control signal output modules only recognize the HDMI input signal, and the HDMI signal is directly output after being transferred by the HDMI switch module (in the case of no 5V power supply, only the HDMI input signal valid, other input signals are invalid), when VGA and two-channel signals are connected again, the HDMI signal is shielded through various signal input conversion control and CEC control signal output modules. At this time, various signal input conversion control and CEC control signals The output module only recognizes VGA and dual-channel signal input as valid, and when AV signals are connected, the HDMI signal, VGA and dual-channel signals are all shielded through various signal input conversion controls and CEC control signal output modules. The signal input conversion control and CEC control signal output modules only recognize AV signal input as valid. When the USB signal is connected again, the HDMI signal, AV, VGA and dual-channel signals are all shielded through various signal input conversion control and CEC control signal output modules. At this time, various signal input conversion control and CEC control signal output modules Only USB signal input is valid. If VGA and two-channel signals are needed at this time, as long as the AV and USB signals are inserted and pulled out, the various signal input conversion control and CEC control signal output modules will automatically recognize the VGA and two-channel signal inputs as valid. That is, during each use, the various signal input conversion control and CEC control signal output modules automatically record the sequence of various signal accesses.
另外,电路板3上还可以根据客户需求可增加蓝牙连接等功能,满足不同的使用需求。 In addition, functions such as Bluetooth connection can also be added to the circuit board 3 according to customer requirements, so as to meet different usage requirements.
