The invention provides a method for transmitting and receiving HDMI video signals based on 60GHz microwave wireless transmission and a method for realizing two-way touch control based on bluetooth wireless transmission of coordinate information. Contains a pair of HDMI signal transceiver modules, with a central processing unit inside to control the work of the HDMI transceiver modules. Firstly, the HDMI video signal is input to the central processing unit, processed by the internal encoder, then sent to the high-end modulator, and then sent to the transmitter module for networking; after the receiver module completes the networking, the HDMI signal is sent to the central processing unit through the network A high-end demodulator is sent to the internal video decoder, and finally the video is output to the terminal display device for display. Connect the touch interface of the display device to the data interface of the processor, the processor reads the touch coordinate information transmitted from the display device and then transmits it to the Bluetooth module through the data port, and uses the Bluetooth protocol to complete the two-way coordinate information transmission and exchange, thereby realizing Two-way touch control.
