Abstract

The invention relates to a collaboration wireless display system, which comprises a source device, a target device and collaboration devices; the source device is respectively connected with a plurality of collaboration devices through a wireless transmission network; the collaboration devices are respectively connected with the target device through the wireless transmission network; and the source device is connected with the target device through the wireless transmission network. The source device transmits display data, the collaboration devices are used for receiving the display data of the source device and for forwarding the display data to the target device, and the target device receives the display data and performs the screen display. Due to the adoption of the system and the working method thereof, not only are the link stability of the wireless screen and the data transmission reliability improved, and is the image quality under a complicate wireless communication environment improved, but also a visual effect of the wireless screen can be enhanced.

Description

technical field [0001] The invention relates to a cooperative wireless screen sharing system and a working method thereof, belonging to the technical field of computer network multimedia transmission. Background technique [0002] With the development of network technology and digital multimedia technology, the free information interaction capability between digital multimedia devices has become the development direction of home appliances and communication industries, so the interconnection and intercommunication between multimedia devices has become a basic requirement. The application of wireless screen transfer technology realizes the wireless interconnection between media terminals (such as smart TVs, mobile phones, tablet computers, notebooks, etc.) natural interaction between them. [0003] The wireless screen transfer technology refers to the interception of the screen display content of the source multimedia terminal through the wireless network, and real-time tran...
