Abstract

The invention discloses a spliced display concurrent processing system, comprising a desktop processor, at least one signal receiving processor and at least one superposition selecting circuit; an output end of the desktop processor and an output end of the signal receiving processor are respectively connected with an input end of the at least one superposition selecting circuit. The signal receiving processor receives and transfers input video images to the superposition selecting circuit after a display processing, the superposition selecting circuit performs a superposition processing to the received video images in accordance with location superposition information transmitted by the desktop processor, and then transmits the video images to a corresponding display unit for output. Various parts of the inventive spliced display concurrent processing system do not occupy scarce computer resources mutually, which fully guarantees respective processing abilities of the desktop processor, the signal receiving processor and the superposition selecting circuit, such that the inventive spliced display concurrent processing system can run effectively, process at the rapid rate, has high refresh rate and lower development cost, maintenance cost and update cost.

Description

Technical field [0001] The invention relates to the field of electronic display systems, in particular to a splicing display parallel processing system. Background technique [0002] As a new type of display device, the splicing display processing system has been widely used. The performance requirements are getting higher and higher, especially the requirements for display speed. For example, the refresh rate of 3D images with more than 5 million pixels is 60Hz, which puts forward new requirements for the transmission rate of display signals; mosaic display walls are in addition to displaying computer desktops or large-scale applications In addition, display output signals from surveillance cameras, DVD players, computers, network display data, and IP video data. For the image information collected by each image acquisition channel, it is usually necessary to superimpose the display output on the entire mosaic display wall. [0003] figure 1 It is a spliced ​​display processin...
