Design And Implementation Of Front End Of Data Push System Based On CMMB

Information Push Technology is the mean through certain technical standards or, protocols to get data from information sources, then send to users through regular channels. This information dissemination system is based on the needs of users, targeted and purposed to push the required information to the users. Information Push Technology has changed the way of accessing to information from search to receive.With the promotion and development of mobile TV technology, people's demand for mobile TV has increased drastically, they are not satisfied with just audio or video programs. Data broadcasting is a new mobile multimedia broadcasting business besides the traditional audio and video service. Data broadcasting system can provide users more services, like images, text, data downloading.This paper gives a design of Information Push System based on CMMB, this system can push graphic, audio and video content and other data services to users through CMMB broadcasting channel. This is a value-added service that provides data based on consumer demand.This Information Push System has following main features: Front-end initiative, without the end-user requests for push content; The user can choose to receive or filter; Automatically transmission and storage without user involvement, support offline use and re-use; The user can immediately access the content that has been pushed and stored; Improve the user experience, especially for large file; Broadcast network bandwidth has been used effectively.This paper introduces the knowledge of information push technology and mobile multimedia broadcasting technology, gives the detailed analysis of the CMMB system. Then this paper gives the overall structure of the information push system. The article focuses on the design and implementation of front-end system.
