When working, the HDMI signal is sent to the HDMI switch module, and then directly output after being transferred by the HDMI switch module. The HDMI switch module has three input ports and one output port

Various signals of VGA and two-channel signals, AV, and USB signals are sent to the central CPU processor, and the various signals are converted into corresponding analog signals or corresponding digital signals by the central CPU processor and sent to the analog-to-digital conversion module. The conversion module converts the analog or digital signal into an HDMI data format and outputs it to the HDMI switch module for direct output after being transferred.

If the TV has CEC function, and the HDMI output cable of the multimedia socket should be connected to the HDMI socket of the TV, after any external signal is connected, the various signal input conversion control and CEC control signal output modules will output a control signal, If the TV is in the standby state, the TV will automatically turn on and enter the playback state. 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.

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.

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.

According to the disclosure and teaching of the above specification, those skilled in the art to which the present utility model belongs can also change and modify the above embodiment. Therefore, the utility model is not limited to the specific implementation manners disclosed and described above, and some modifications and changes to the utility model should also fall within the scope of protection of the claims of the utility model. In addition, although some specific terms are used in this specification, these terms are only for convenience of description, and do not constitute any limitation to the present invention. The use of other sockets identical or similar thereto is within the protection scope of the present invention.
