Abstract


With the needs and aspirations of the rapid growth of the Chinese audience personalized , digital TV - based video-on-demand ( VOD ) system , more and more attention , but there are still many problems in the course of its development . Such as program source of the film is too old , the ratings are way too single , the lack of interactive user interaction , far unable to meet the needs of users ; addition , the system is not unified , open interfaces, system expansion , cross-platform support , with the first tripartite integration of value-added applications are difficult to achieve ; this greatly hinders the further development of the cable industry . With the development of the \Therefore, set up a meet the various needs of users , and has strong vitality of the the VOD technology platform will be an important task for the cable industry . This paper analyzes the development of VOD and interactive VOD business advantage , based on HFC cable network design transmission system architecture designed to develop TV look back at the core functionality of interactive services , TV appointment and system processes . Based on this analysis based on the overall structure of the ISA architecture interactive VOD system , subsystem framing . The deeper study business management system , session resource management system , the media management system , subsystem and video servers, time-shifting collection equipment, application servers and other equipment Fine deployment . And for a variety of interactive services in accordance with its operational characteristics , the use of HTML / HTTP, FTP, LSCP agreement , Pause Live, nPVR interactive industry carried out a detailed design . The ultimate realization of interactive VOD system based on HFC network . Confirmed the practical test of the Beijing area users , the system reached the desired effect.
