China mobile multimedia broadcasting (CMMB)-based rich media audio broadcasting front-end and system

Abstract

The invention discloses a China mobile multimedia broadcasting (CMMB)-based rich media audio broadcasting front-end and a CMMB-based rich media audio broadcasting system. The rich media audio broadcasting front-end is used for producing CMMB audio data and CMMB markup language (CML) data, multiplexing the CMMB audio data and the CML data into a multiplexed stream by using a CMMB multiplexer, and transmitting the multiplexed stream to a CMMB-based rich media audio broadcasting terminal. The rich media audio broadcasting front-end comprises a service management unit, a data broadcasting unit and an audio coder, wherein the service management unit is used for managing the CML data which is produced by a content provider / service provider according to broadcasting information provided by the content provider / service provider, outputting the CML data to the data broadcasting unit, and managing data interaction with the CMMB-based rich media audio broadcasting terminal; the data broadcasting unit is used for receiving the CML data, performing format conversion on the CML data to be transmitted, and transmitting the format-converted CML data to be transmitted to the CMMB multiplexer; and the audio coder is used for compressing and coding an audio program source to form the CMMB audio data, and outputting the CMMB audio data to the CMMB multiplexer.

Description

technical field [0001] The present invention relates to the technical field of CMMB (China Mobile Multimedia Broadcasting, China Mobile Multimedia Broadcasting), in particular to a CMMB-based rich media audio broadcast front end and system. Background technique [0002] With the rapid development of communication technology and computer technology, people have higher requirements for the application of mobile terminals. People are no longer satisfied with basic functions such as simple calls, sending and receiving short messages, but more multimedia applications. Mobile phones can be used to obtain various information, such as broadcasting, constellations, tourist destination weather introduction, video playback and on-demand, etc. Existing mobile terminals usually obtain the above information through WAP, but the speed of obtaining video information through WAP cannot be guaranteed . Contents of the invention [0003] In order to solve the above-mentioned problems existi...
