Stream medium system and method capable of supporting abundant medium business

Abstract

The invention discloses a streaming media system for supporting rich media service, which comprises a mobile terminal, a scene server and an application server. The mobile terminal is used for transforming a local scene according to a DOM event, requests the scene server to obtain a scene, carries out demultiplexing and decoding on received multiplexing stream, and maintains the scene; the scene server is used for generating a new scene or updating the scene according to the request of the mobile terminal, obtains correlative media data from the corresponding application server, and is used for multiplexing the obtained media data and the stored scene into the multiplexing stream and sending the multiplexing stream to the mobile terminal; and the application server is used for coding the corresponding media data according to the request of the scene server. The invention also discloses a method for supporting the rich media service. The system and the method do not need excessive sockets, can keep time synchronization among the media better, and greatly shorten waiting time of a user by using a mode of downloading and playing synchronously, and have strong real time.

Description

technical field [0001] The invention relates to the communication field, in particular to a streaming media system and method supporting rich media services. Background technique [0002] Rich media (a dynamic interactive collection composed of audio, video, graphics, text and other multimedia data) is no longer new to be transmitted on the Internet and played on a PC, but for mobile networks, due to the high latency and low bandwidth of wireless networks As well as problems such as low performance of terminal equipment and inconsistent screen resolution, rich media has not been widely used. MPEG-4 BIFS (Binary Format for SceneDescription, binary format for scene description) cannot be applied to mobile terminals because its content organization and binary coding structure do not take into account the characteristics of mobile systems. As the main form of rich media on PCs, FLASH has achieved great success on the Internet, but due to its patent factors, it cannot obtain gre...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to propose a streaming media system and method supporting rich media services, which solves the problem that various media in the prior art services occupy too many socket resources, and at the same time reduces the cost caused by establishing too many transmission links. a lot of latency issues
