Method and display system for large-screen projection on the wall based on network combined video stream desktop

Abstract

The invention provides a desktop on-the-wall large screen projection method based on network combined video streams and a display system thereof. The system comprises a video application module of anapplication client workstation, a sending display network module of the application client workstation, a local decoding module of the application client workstation, and the like. Video sources sendnetwork video streams to the local decoding module and send the network video streams to an on-the-wall decoding module at the same time. When the sending display network module sends an application client desktop, video source display parts are removed, and positions and sizes of the video sources and video frame synchronization information are carried. A receiving display network module receivesthe videos of the client desktop, adjusts the video frame resolution of the application desktop to the display resolution on a large screen through utilization of an image interpolation method, combines the images of the video sources of the on-the-wall decoding module into a complete desktop image according to the positions of the video sources and the video frame synchronization information andsends the complete desktop image to an on-the-wall display module. The display resolution of the video sources on the large screen is improved, and a display effect of the large screen for the videosources is improved.

Description

technical field [0001] The invention relates to the technical field of cloud computing and network communication, in particular to a method and a display system for projecting a large screen on a desktop with a combined video stream based on a network. Background technique [0002] Video applications mainly include video applications such as video surveillance, but also non-video applications such as GIS. In the command center, the workstation video output of the video application client is usually put into the TV wall matrix, and all operations performed by the operator on the application client are synchronized. Splicing large-screen display in TV wall matrix, see figure 1 shown. The local desktop of the application client is usually enlarged by the video wall to bring a greater look and feel, but it also brings a problem. For example, the resolution of the video source is 1080P, the resolution of the local desktop of the application client is also 1080P, and the video so...

AI Technical Summary

Problems solved by technology

At this time, the camera displays 1080P pixels on the wall and desktop of the application client, but can only display 720P enlarged images. The actual display resolution of the video source has a huge impact on the final display effect, so the final display effect is severely reduced, and a better one is needed. way to solve the problem
