The project achieves the data services via Ethernet transceiver, realizes VoIP services in conjunction with the DSP which have voice compression processing functions;With the collaboration of AVIA9700-QCK and FH8601,the two chips can deal with two kinds of video signals encoded by MPEG-2 and H.264. Especially on the aspect of the video business,the system combines the advantages of IPTV and the DVB to offer a platform for receiving two signals,allows users to use an ordinary television which can both watch there content-rich resources of high-definition digital TV programs encoded by MPEG-2 and watch time-lapse and interactive IPTV video programs encoded by H.264.It meets the needs of users requirements of watch high-definition and interactive television program.In the conditions of EPON,it achieves the broadcasts of high-definition programs,along with the access and return of data,voice and other business-wide.Through the simulation analysis,we focuses on the two encoding mode on the impact of bandwidth consumption and make analyse and comparison through simulation.we can intuitively see the advantages of H.264 video coding in the video-on-demand business.On the perspective of benefits and technique,video-on-demand system based on H.264,will be the development trend of the VOD business.
