Method for realizing screen projection from single PC screen to multiple different device screens

Abstract

The invention provides a method for realizing screen projection from a single PC screen to multiple different device screens. The method comprises the following steps of (1) deploying screen projection software on a source terminal device to realize screen audio-video data acquisition and reception of a terminal, and sending audio-video data by using an RTSP protocol through H264 standard coding compression; (2) establishing local area network communication between the source terminal device and a display terminal device; (3) providing a display operation interface by the screen projection software, and displaying a searched display terminal device list in a local area network, wherein a user can check a plurality of display terminal devices for output and display; and (4) deploying display software on the display terminal devices to realize search response to the source terminal device, and decoding, displaying and outputting the received audio-video data subjected to the H264 standard coding compression. According to the method, the purpose of projecting screen audios and videos of a terminal to a plurality of terminals for display without a forwarding server in a wireless screen projection application at present is achieved.

Description

technical field [0001] The invention relates to a method for realizing projection of a single PC screen to multiple screens of different devices. Background technique [0002] Existing technical solutions can be used for one-to-many screen projection through wires or wireless methods, but one-to-many in wireless projection cannot be realized. One screen needs to be wired to project multiple screens, and it is greatly affected by the construction environment. The transmission distance and the number of screens are very limited. Contents of the invention [0003] The present invention proposes a method for realizing projection of a single PC screen to multiple screens of different devices, and solves the problem that in the current wireless projection application, in the absence of a forwarding server, the audio and video of a terminal screen cannot be projected to multiple terminals for display (Because the data that the network card of the source terminal can send at the ...
