The Design And Implementation Of TJBTN VOD System Media Distribution Network

MDN system, that is, media distribution network, as a VOD video request systemis of vital importance to the link, this system can realize to the media’s record, storage,distribution, and so on the many kinds of VOD business.This paper discusses the MDN system hardware and software design method. Thepaper topics first analysis of the construction of two-way interactive businessbackground, points out that the construction hd interactive TV system (compatible withstandard and video format clear), development hd interactive TV business importanceand necessity. For VOD system after the design theory of knowledge, industrystandards and professional term for VOD system for the whole in the paper. And thendiscusses the VOD system video distribution system framework and realization, pointsout that in the video distribution system for the design and implementation of technicalproblems to solve and finally realize the way.Based on this, the comprehensive detailed description of the video distributionsystem operation of the overall structure and the design and realization of the modules,including vod system program storage, distribution and push the flow design andimplementation; Medium resource access platform (MAP) in the function of videodistribution system; The database to the media distribution system functions; Videoserver (VS) in the recording, pushing flow, distribution of the method; Center storageserver in the film on demand, the function of distribution. Video distribution systemanalysis software configuration, description of the whole system operation ability;Analysis on the user requested to realize from the motion, playback and when demandoverall business process; Analysis in video distribution system is running functionaltest report, specific analysis on video on demand quality of the important parameters,this paper mainly analyzes the case, analyzes the study corresponding solutions;Describes system improvement scheme and the concrete implementation method. Inthe end, system overall operating conditions and application status summary do, andfuture prospects of system to prospect.
