NVD Program Player System On The Base Of Personal Computer

In recent year,with the rapid development of multimedia technology,HD video is inthe climax of a development,HD video source is increaseing and more and more diversification,next generation of HD video disc has a strong market demand.In this form,withindependent intellectual property rights,"the next generation of red HD network video discplayers"came into being,in the case of compatible DVD,take a large number of independent research and development,has a full support for HD video playback.as basic functions technology continues to improve,with many aspects of the patented technology, introduced a lot of use with the current commercial,scientific and technological development,develop ment in the two aspects of the core technology and industrializa tion, ICS system,VODsystem,intelligent community all are new applications are introduced in the context of network development.Launched to support NVD player in the PC also an importantmeasure to promote the industry chain of NVD.The popularity of PC and the development of hardware and soft ware level allowsthe study of HD video playback on PC,in addition to decode and show HD video in thesystem of player,also support the navigation and video formats of NVD,to NVD-ICSauthentication system, you also provide functions of network authentication and fill videoetc.An middle layer extracted from the system of player,take the differences of differentsources of video programming in the processes、input/output formats、 interface and otheraspects to the middle layer processing,can improve the scalability of system software. Thismiddle layer provides a common interface,with add sub-module can be completed to thesupport programming in the processes、 input/output formats、 interface of other sourcesof video.The copyright protection of system software and NVD, achieve by hardware_based encryption provied by software dongle,use dedicated hardware to start the normaloperation of the system software.This need research the principle of encryption chip, theencryp tion process as well as conversion between the different protocol interfaces etc.Atthe same time,in order to provide convenience of opera tion, operating interfaces ofsystem software optimized. Test results show that, player system this article is designed to achieve not only provide for NVD and NVD-ICS support of navigation and playback, also provide supportfor other common format video.
