Abstract

The embodiment of the invention discloses a decoding method, server and system for superimposing windows, which solves the technical problem of window opening failure caused by limited decoding resources in the current window superimposing mode. The decoding method of the superimposed window in the embodiment of the present invention includes: the window decoding task refreshing module triggers the decoding task of the mosaic wall display node corresponding to the window operation according to the obtained window operation instruction; the window decoding task allocation module performs the decoding task of each display node Analyze, and determine the display node corresponding to the window to be operated corresponding to the window operation instruction according to the window information corresponding to the window operation instruction and the display position information of each display node on the splicing wall; the window decoding task assignment module judges the determined display node Whether the window to be operated is completely covered, and if so, stop assigning the decoding task corresponding to the window to be operated to the determined display node.

Description

technical field [0001] The present invention relates to the technical field of signal processing, in particular to a decoding method, server and system for superimposing windows. Background technique [0002] At present, the splicing wall system has been applied to many system fields including transportation, electric power, security and so on. Putting various application software and monitoring video images on the splicing wall greatly facilitates people's monitoring of various data, and provides the possibility for data analysis and rapid resource allocation. [0003] As an important product type of video wall processors, distributed processors occupy a special position in large video wall products because of their flexible scalability. Such as figure 1 As shown, generally speaking, a distributed processor is composed of a main server and a display node machine. The main server is responsible for the management of system resources and the distribution of video data, and ...
