Wireless video transmission method

Abstract

The invention discloses a wireless video transmission method. The wireless video transmission method includes following steps: 1) starting a receiving terminal, and starting an AP (access point) and a DHCP (dynamic host configuration protocol) service module of the receiving terminal and a decoder; 2) starting an upper computer, connecting the upper computer with the receiving terminal by connecting the upper computer into the AP of the receiving terminal through a WEB (world wide web) server, and obtaining an IP (internet protocol) address through the DHCP service module; 3) enabling upper computer software to start to capture a screen so as to obtain screen capturing data, transmitting coding data obtained by coding the screen capturing data to the receiving terminal, and generating data between the upper computer and the receiving terminal so as to obtain a data link; 4) decoding the coding data received by the receiving terminal through the decoder so as to obtain decoding data, and transmitting the decoding data to a display device through a HDMI (high definition multimedia interface) or a VGA (video graphics array) interface so as to display the decoding data. The wireless video transmission method sends a screen of a computer or a mobile phone to the receiving terminal through a wireless network in real time, converts the screen of the computer or the mobile phone into HDMI or VGA signals, transmits the HDMI or VGA signals to the display device for display, and thereby can effectively solve an HDMI or VGA wiring problem.

Description

technical field [0001] The invention relates to a wireless video transmission method, belonging to the technical field of wireless video transmission. Background technique [0002] Existing wireless video transmission technologies, for example, WHDI uses ultra-wideband transmission, which requires special WHDI hardware support, and the computer must support WHDI to use it. If external interface hardware is used, then when switching user displays, the hardware needs to be pulled out and handed over to Another user, another user can only perform wireless video transmission after plugging in, which seriously affects the wiring of the terminal and the plugging and unplugging of the input source. And usually video transmission uses time stamps to control the time interval between frame rates, which will cause video time delay and affect customer experience. Contents of the invention [0003] In order to overcome the shortcomings of the prior art, the present invention provides...
