Method for real-time mapping video signals of mosaic display screen at control terminal

Abstract

The invention discloses a method for real-timely mapping video signals of a mosaic display screen at a control terminal. An H.264 coding device is arranged before the input end of a image mosaic processor, one output end of the H.264 coding device is connected with the input end of the image mosaic processor, and the other output end of the H.264 coding device is connected with a control terminalcomputer via a network cable connected with the network signal input port of the control terminal computer. The invention has the following advantages that: the content of the large mosaic display screen, which is displayed on the software operation interface of the control terminal computer, is not transmitted back by the image processor but is transmitted back as signals taken before the input end of the image mosaic processor; since the acquired IP video steam is compressed, the code stream is small, the IP video steam can be recorded and played back when needed, and consequently, the invention solves the problem on how to remotely operate and manage the mosaic display screen, and realizes the window display of specified input signals on the large mosaic screen and the real-time display of the specified input signals on the virtual interface of the control terminal computer.

Description

technical field [0001] The invention relates to a method for realizing mapping of video signals on a large-screen splicing display screen at a control end, in particular to a method for realizing real-time mapping of video signals on a splicing display screen at a control end. Background technique [0002] The existing large-screen splicing display is composed of multiple independent display units, which are driven by a splicing image processor to form an ultra-high-resolution large screen. In order to facilitate the operation of the display signal on the large screen, the software that controls the large screen Generally, the service / client structure is adopted. The server is generally installed on the splicing processor, and the client software is usually installed on the computer at the control end. A virtual box, on which the user opens a window, zooms in and out of the window, and closes the window, there will be corresponding actions on the corresponding spliced ​​larg...

AI Technical Summary

Problems solved by technology

In order to reduce the impact of image return on the processing ability of the image processor, generally the content displayed on the splicing screen returned to the control computer is displayed on the operating software interface, and the display is refreshed every few seconds and the resolution is very low, which cannot be seen clearly. content, and cannot be videotaped, which brings certain difficulties to actual use
