Implementing method and system for mobile multimedia data broadcast service

Abstract

The invention provides a method and a system for realizing a mobile multimedia data broadcasting service. The service system comprises a data broadcasting transmission subsystem, a content providing server and a data broadcasting server, wherein, the content providing server is used for generating and outputting a service file of the data broadcasting service; the data broadcasting server is used for receiving the service file outputted by the content providing server and acquiring corresponding formatting information, splitting and encapsulating the service file according to the encapsulation standard of the mobile multimedia data broadcasting, and transmitting an encapsulated service file data packet in a broadcasting channel by the data broadcasting transmission subsystem according to the formatting information. The method and the system can realize the data broadcasting service in a file mode, realizes the separation of a content provider from a network operator by arranging the independent content providing server and submitting the service file and the corresponding formatting information to the content providing server, thereby establishing a flexible operating platform for providing rich service contents.

Description

Technical field [0001] The present invention relates to mobile multimedia broadcasting technology, in particular to a method and system for implementing mobile multimedia data broadcasting services. Background technique [0002] In recent years, digital wireless mobile multimedia broadcasting technologies and standards have developed rapidly, such as the DVB-H (Digital Video Broadcast Handheld) system in Europe, and the MediaFLO (Media Forward Link Only) in the United States. ) System and China’s CMMB (China Mobile Multimedia Broadcasting) system, etc. [0003] The data services defined by the CMMB system standard are divided into two types: stream mode and file mode. Data services in stream mode are provided in the form of data streams. Usually, the transmission of data streams has timing requirements, including time stamp indications or synchronization requirements within the data stream; data services in file mode are provided as discrete files, and data transmission No timing...

Problems solved by technology

[0004] Although the CMMB system standard has defined the bearing and block transmission standards of data services, there is no way to adopt the above-mentioned standards in the prior art to provide file mode data services (such as mobile newspapers, news content, government affairs, business information, etc.) in the CMMB system entertainment games, weather forecasts, file downloads, etc.) specific methods and system architecture
