The Research And Implementation Of IPTV Distributed System Based On HLS

With the booming popularity of multimedia technology and broadband networks, the major broadband operators began to pay attention to a variety of value-added services, the Applied Ecology chain of broadband is slowly formed. IPTV is just such a platform. It will promote the prosperity and development of content providers, and provide users with a convenient, interactive digital media services. Due to the unified IPTV system interface and the lack of specifications, it is in urgent need of an open IPTV standard systems.Based on the situation of current IPTV study and IPTV system’s key technology, In-depth study focused on IPTV system load balancing strategies and streaming media data transmission protocol. To optimize the traditional threshold value based on the dynamic replication strategy, It would combined with video on demand weight; For the simple applicable HLS protocol of streaming data transmission protocol, it has been optimized to reduce the response time of the user’s request. Then with the research of the system structure of IPTV, based on C/S mode IPTV distributed system framework is proposed. At the same time, the interaction between each server specification interface has been standardized, and it has good openness and scalability. Through the the HLS protocol transmission mechanism and improved load balancing technology, effective protection of the IPTV system QOS solve the video quality security issues in different network environments, but also has a good network security. The solution of these problems, has a great role in promoting the development of IPTV.On this basis, based the HLS HD IPTV system design and realization. The system is able to support a large number of concurrent user access to different network environments, quality service and to protect the security of user information.
