The Design And Implement Of Service Control Subsystem Of IPTV Interactive Platform

As the developing of IPTV services and the growing of IPTV user group, the interactivities between IPTV operator and IPTV user becomes more valuable. The operator needs one kind of platform to realize the interactive services between the user and operator.In this thesis, first of all, introduces the current status of IPTV, the concept of IPTV, the component of the IPTV system and its supporting service type based on technical platform. It also describes the concept of middleware and the function of IPTV middleware, refers to the ORCA RiGHTv system which integrated to VCIS platform, then make detailed description of its functions. After this, thesis begins from the situation of the IPTV's immature supporting to interactive services, educes the idea of design VCIS platform which is one kind of IPTV interactive services platform. Next step, makes detailed description and type partition of the services, then designs the structure of the VCIS platform. After this, thesis describes the concept of the services, the design pattern of the services, and then through the simulation of one IPTV user watching one football competition, emphasizly describe the design and implement of the two modules:service production center module and service control module, these two modules are the component modules of service control subsystem. At the last, design some use cases to test with client side to prove the good support of interactive services by VCIS platform.To sum up, the work of this thesis could be summarized as followings:1. Introduce IPTV related background knowledge. Then makes detailed description of structure of VCIS platform and its supporting service type, educes the module of service control subsystem.2. Describe the concept of the service, makes detailed description of service design pattern, suggest the design view of service template and service instance.3. Redesign and implement the service control subsystem which concludes the redesign and implement of service production center module, the redesign and implement of service control module.
