Abstract

The invention discloses a DVB (Digital Video Broadcasting) transmission-based high-definition online inspection system, which relates to the technical field of DCB. The system comprises an audio and video signal acquisition end, an audio and video signal receiving end, a lower-level display device and an upper-level command center, wherein the audio and video signal acquisition end is connected with the audio and video receiving end; the audio and video receiving end is connected with the lower-level display device; and the audio and video receiving end is also connected with the upper-level command center. The system has the beneficial effects of front-end 1080P full high-definition video acquisition, local 1080P full high-definition video storage, local 1080P full high-definition video large screen display and upper-level automatic transcoding display. Network bandwidth is applicable; coaxial cable signal transmission is adopted locally; a single cable can be connected with 99 cameras maximally; illegal stealing of the local video can be effectively prevented; the project, the construction and the daily maintenance are simple, time-saving, labor-saving and money-saving.

Description

technical field [0001] The invention relates to the technical field of DCB, in particular to a high-definition online inspection system based on DVB transmission. Background technique [0002] DVB (Digital Video Broadcasting) is a series of internationally recognized digital TV open standards maintained by the DVB project, which are widely used in digital TV and broadcast transmission media. [0003] The traditional high-definition online inspection system adopts the TCP / IP protocol technology architecture, which mainly faces the following technical bottlenecks: [0004] 1) Test center bandwidth limitation: The standard transmission rate of 1080P full HD video is 6Mb / s. When multi-channel high-definition video is distributed, uploaded, retrieved, and concurrently played, the bandwidth requirements of the test center are high. In order to ensure smooth image playback, the traditional TCP / IP architecture usually implements multi-stream splitting applications for cameras, and ...
