Design And Implementation Of IPTV/OTT TV Hybrid-terminal Authentication System

With the rapid development of broadband network, hybrid-terminal has become the core part of smart home. In order to support authoritative IPTV service as well as diversified OTT TV service, authentication system for hybrid-terminals is vital in the whole implementation.Shanghai Telecom IPTV/OTT hybrid-terminal authentication system was designed and developed under the comprehensive analyses of service characteristic and new technology research. The system is divided into three sub-systems, that is terminal management module, ETV service management module and CDN access management module. And the terminal device is developed in Client-Server mode. It communicates with the server by Simple Object Access Protocol(SOAP) to complete terminal authentication, service authentication, IPTV service authorization, OTT service authorization and CDN access. The server is developed by JAVA language, SQL database, and other network technologies. It has functionalities of STB terminal identification, terminal authentication, IPTV/OTT services authorization and system management. This solution aims at the performance improvement on system security, zero-configuration service registration and intelligent CDN service. Eventually it can improve service efficiency and quality and provide enhanced user experience. This thesis focuses on architecture design to acquire high performance to cope with users’large concurrent access of IPTV/OTT service. From the technology implement point of view, it mainly applies advanced technologies as load balancing, concurrency control, EhCache application cache, Blocking-Queue first-in-first-out blocking queue, independent Memcached cache, Oracle RAC real-time application cluster. These technologies play an important part in obtaining high flexiblity, stability and reliability.IPTV/OTT hybrid-terminal authentication system has been successfully used in Shanghai. By September this year, Shanghai Telecom has developed 0.1 millions of 4K users. It further strengthened the security of intelligent terminals and promoted the development of Shanghai IPTV 4K service. It also provided more richer broadband applications and developed the value-added services such as OTT TV, App store and game play.
