Decoding method, server and system of superimposed windows

Abstract

The embodiment of the invention discloses a decoding method, a server and a system of superimposed windows. The technical problem that the window opening existing window superimposing mode is failed due to limited decoding resources is solved. The decoding method of the superimposed windows of the embodiment of the invention comprises the following steps: a window decoding task refreshing module triggering the decoding task of a spliced wall display node of the corresponding window operation according to an acquired window operation instruction; a window decoding task distributing module analyzing the decoding task of each display node, and determining the display node corresponding to the to-be-operated window 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 spliced wall; the window decoding task distributing module judging whether the to-be-operated window of the determined display node is completely covered, if so, stopping distributing the decoding task corresponding to the to-be-operated window 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. like 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 the...
