Transcoder ofuniversal video monitoring platform

Abstract

The invention provides a transcoder of a universal video monitoring platform, comprising an interface unit and a system control module, a resource acquisition module, a resource selecting module, a video acquisition module and a DSP encoding module respectively connected with the interface unit by buses, wherein the resource acquisition module is used for reading monitoring resource node data in the client memory page of the existing video monitoring platform; the resource selecting module is used for switching the client of the existing video monitoring platform, connected with the transcoder of the universal video monitoring platform, under the control command of the system control module; the video acquisition module is used for intercepting video data in client show video cache of theexisting video monitoring platform; and the DSP encoding module is used for carrying out H.264 encoding on RGB or YUV video data acquired by the video acquisition module and then synchronously outputting analog video signals and digital video code streams with H.264 formats.

Description

technical field [0001] The invention relates to a universal video monitoring platform transcoder. The invention belongs to the technical field of image communication, and in particular relates to a device capable of uniformly scheduling and transcoding images of various video monitoring networking platforms. Background technique [0002] According to statistics, before 2008, my country's video surveillance applications were mainly concentrated in government departments and special departments and industries such as finance, public security, transportation, and electric power. Among them, the government sector and the financial industry accounted for 20.9% and 20.6% of the market share respectively. However, with the advancement of social informatization, the demand for video surveillance in more and more industries and fields has increased significantly. So far, video surveillance has begun to extend from individual fields such as banking and transportation to multiple fiel...
