Method and system for processing mobile multimedia data broadcasting services

Abstract

The invention discloses a method and a system for processing mobile multimedia data broadcasting services. The method comprises the following steps: distinguishing a plurality of data services according to port number, and setting a service receiving unit, a service transmitting unit and a shared buffer memory independently for each path of data services, wherein processing for each path of data services comprises: the service receiving unit receives data and stores the received data to the tail part of the shared buffer memory; and the service transmitting unit reads data from the head part of the shared buffer memory and transmits the data. The invention greatly improves the efficiency of processing services in real time by a protocol packager by adopting a way of processing a pluralityof paths of services in parallel in a CMMB data broadcasting system, and controls the delay time within millisecond grade; in addition, the invention greatly lowers the packet loss rate of the data by adopting a congestion control mechanism in the CMMB data broadcasting system.

Description

technical field [0001] The present invention relates to the technical field of mobile multimedia data broadcasting, and more specifically, to a method and system for processing mobile multimedia data broadcasting services. Background technique [0002] In recent years, digital mobile multimedia broadcasting technology and standards have developed rapidly, such as DVB-H (Digital Video Broadcast Handheld, digital video broadcasting handheld reception) in Europe, MediaFLO (Media Forward Link Only, media single forward link) in the United States and China's CMMB (China Mobile Multimedia Broadcasting, China Mobile Multimedia Broadcasting), etc. [0003] Data broadcasting is a value-added service of mobile multimedia broadcasting, which expands and enriches the business content of mobile multimedia broadcasting. It is very important to formulate data broadcasting standards to promote the development of mobile multimedia broadcasting services. Data broadcasting transmits a variet...

Problems solved by technology

At present, there is no specific technical solution on how to implement multi-channel business processing

[0010] At the same time, in this process, the rate of the business source is variable, which may cause data packet loss. The current technology mainly uses window-based congestion control, such as the widely used network transport layer protocol TCP and its variants. Wait

Generally, the processing is relatively complicated. For data broadcast services with large data volume and high real-time requirements, a UPD congestion control mechanism with relatively convenient processing and fast processing speed is required.
