System and method for realizing multi-media service in wide-band video system

Abstract

This invention discloses a system for achieving the multimedia service and a method thereof, which is used for achieving the multimedia service in the broad band video network. The core conception of this invention is: configuring a service platform which functions as multicast user management in the broad band video network; obtaining the multimedia data and user terminal information for receiving the data according to the information contained in the video-on-demand request of the user terminal, transmitting the multimedia data and user terminal information for receiving the data from the service platform to the video flow user distributor corresponding to the user terminal for receiving the data and distributing the multimedia data to the user terminal for receiving data by the video flow user distributor. This invention can satisfy the requirement of transmitting the multimedia program to specific user terminal on demand, enrich the content on-demand of the user terminal and the formation of the multimedia service and can improve the flexibility of the multimedia service. So that this invention can further satisfy various video-on-demand requirements of the user terminal.

Description

technical field [0001] The invention relates to the technical field of broadband video, in particular to a system and method for realizing multimedia services in a broadband video system. Background technique [0002] Multimedia services such as inserting subtitles and on-demand programs in TV programs have become an indispensable part of TV programs. [0003] Because traditional TV broadcasts TV programs in the way of broadcasting, subtitle prompt information such as program preview, rolling news and other text information will be sent to all user terminals after being attached to a certain, multiple or all channels. The program will also be distributed to all user terminals. Traditional TV cannot provide specific multimedia services for specific user terminals. [0004] The broadband video system can provide video-on-demand service VOD for the user terminal. The user terminal can order TV programs in the program table provided by the service provider as needed, and the s...

Problems solved by technology

[0005] At present, the broadband video system can only provide the user terminal with the video service of predetermined program content according to the user terminal's request, and cannot meet the user terminal's demand for other user terminals to order TV programs. Moreover, the user terminal needs to be online when ordering TV programs Application, the TV program applied for must be the TV program in the program list provided by the service provider, and can only be played in the form of ordinary TV programs, and the playback format is single, and it is necessary to forcibly switch the TV program currently being watched by the user terminal, so that the existing The implementation flexibility of multimedia services is poor, and it cannot meet various on-demand requirements of user terminals.
