Iptv System Design And Deployment Research For Tianjin Unicom

"IPTV is defined as multimedia services such as television, video, audio, text, graphics data delivered over IP based networks managed to provide the required level of quality of service and experience, security, interactivity and reliability. The appearance of IPTV has brought the new business income growth for telecom operators. At the same time, IPTV’s service development and its requirement of bandwidth will promote the telecom operators to update their broadband networks. Therefore, both the system design and the deployment and test of IPTV have a great significance for telecommunication industry.This paper introduces the basic principles related to IPTV, and then with Tianjin Unicom as a study case, proposes IPTV’s market demand for Tianjin Unicom, including the number of online users, the number of live channels, duration of video on demand, the offer of time shifting and playback, and the proportion of SD and HD channels etc. Then the deployment scheme of IPTV is designed according to the market demand analysis, including the node network condition, the number of servers and storage capacity. Tianjin Unicom metro and access network status are taken in to consideration, including the core, aggregation and access layers of the device model performance, network structure, the Internet relay bandwidth. Combining the above indicators and the demand of IPTV service, network upgrade and expansion program is proposed. At last, the reliability of the conceptual design of IPTV service is testified by the testing of relevant IPTV services after the accomplishment of the system deployment.After official commercial use of Tianjin Unicom IPTV system, its platform and bearer network have stood the actual inspect. In the recent year, the stable performance and optimized network structure has brought a good sense of experience to the users. Therefore, IPTV service has made a rapid development and attracted a great number of users, which has brought new business income growth to Tianjin Unicom and also enhanced its competitiveness, which fully demonstrates that the design scheme of the platform system and network upgrade is greatly successful. These achievements have profound referential significance and important guiding function for the development of similar new services and the design of more reliable and stable new system.
