| A provincial Broadcasting and TV Network Group is mainly based on the HFC network for public transport base video business,such as live,time-shift,video-on-demand,etc.At present,this province has completed the coverage of FTTH network in some communities and cities,but in an all-optical and fully IP Network environment,the end-to-end technology system needs to be fully updated and evolved.Therefore,in order to keep up with the pace of the entire network IP,this provincial BTNG need to consider to build a new IP-based video platform on the basis of the original DVB platform,and take the advantages of IP to develop more basic video services and other kinds of services.In this way,this provincial BTNG can meet the requirements of business development,under the new situation.This project discusses the construction of a set of IP video platform which based on the environment of a provincial broadcasting and TV network.It can provide quality assured Services for the entire network users,and has the ability of smooth upgrade,which can be expanded with the scope of business expansion and user scale.This IP platform has the ability to support the powerful content and business integration at the same time,which can integrate multiple mass content of several content Service platforms at the operational level and provide various types of business Services to meet the diverse needs of users.Meanwhile,this IP platform has the ability to carry out the business Service of three network integration and can be docking with other three network integration business subsystem,which provides technical capacity and business innovation capacity protection for the introduce of new formats and new technologies.This thesis aims to design the service and system structure of the IP platform,and clear the requirements of IP platform according to the current business and future trend of the development.Furthermore,this thesis has carried on the concrete practice and test and finally completed the study goal.This thesis can enrich the content of the interactive TV of this provincial BTNG effectively and improve the efficiency of project construction.Based on software engineering theory,this thesis detailedly introduces the business requirements,functional requirements,performance requirements of IP platform as well as discusses the overall of the platform architecture and the specific system design.In addition,this thesis also gives the implementation process of the important system and the specific effect of the IP platform. |
