The invention provides a method for transmitting and receiving HDMI video signals based on 60GHz microwave wireless transmission and a method for realizing bidirectional touch control based on Bluetooth wireless transmission coordinate information. A system comprises a pair of HDMI signal receiving and transmitting modules, and a central processor is arranged in the HDMI signal receiving and transmitting modules to control the HDMI signal receiving and transmitting modules to work. An HDMI video signal is firstly input into the central processing unit, processed by the internal encoder, then sent to the high-configuration modulator and then sent to the transmitter module for networking; after networking is completed by the receiver module, HDMI signals are sent to the high-definition demodulator of the central processing unit through a network and then sent to the internal video decoder, and finally videos are output to the terminal display device to be displayed. The touch interface of the display device is connected to the data interface of the processor, the processor reads the touch coordinate information transmitted by the display device and then transmits the touch coordinateinformation to the Bluetooth module through the data port, bidirectional coordinate information transmission and exchange are completed through a Bluetooth protocol, and therefore bidirectional touchcontrol is achieved.
