Design And Realization For The Electronic Program Guidance's System In The Field Of Digital Television

Electronic Program Guidance is an important part of the digital television(DTV), it is the best form for the realization of kind user interface, and it also can reflect the increment operation of digital television directly. Then it has a great significance for the both administration of front end of DTV and realization of new service.This paper mainly introduces the system analysis and architecture design for the EPG system in the DTV field, and it particularly states the design plan and practical realization methods for the 4 modules: Edit-End, Broadcast-End, Monitor-End and Database. And it gives a deep analysis for the core technology and difficulty in the key modules.Since 2004,The State Administration Of Radio Film And Television decided to adopt the DVB-C of the Euro DVB organization as the national standard for the DTV of China, so this system keep a consistence with the market demand for the domestic DTV.This project has been finished for the practical using with a high level in the function expansibility, system stability and operation convenience. Comparatively, it leads a lot to all other existing system.It can be predicted that DTV will experience a fast boom in the future several years, and current DTV operation can poorly meet the increasing consumer demand. The R&D of new operation system will be critical for the DTV development, and EPG will stand firmly as the tie between the front-end and the terminals, so it will make a great achievement with the progress of DTV.
