Problems solved by technology

The design of the multiplexing frame structure realizes the high-efficiency transmission of media data in the mobile multimedia broadcasting system. By stripping the user data protocol UDP and the Internet protocol IP, the real-time transport protocol RTP package is directly used for the encapsulation and transmission of the multiplexing frame, which improves the system data. At the same time as the transmission efficiency, it also brings certain difficulties to the terminal development. There is no complete IP protocol cluster on the terminal, and the development platform needs to be adjusted and transformed, especially affecting the business application development of future terminals, increasing the difficulty of business application development

Abstract

This invention discloses a transmission method for IP data, which picks up IP packet head key information containing a source address and an aim address and IP data packet net charge from an IP data packet, packages the IP packet head key information in the control information of multiplex frame 0 according to a criterion of mobile multimedia broadcast multiplex structure or the multiplex sub-frames of other frames or in the ESG and packages the net charge in the video segment, audio segment and data segment of the sub-frames in terms of the criterion, and the packaged frames are transmitted to mobile multimedia terminals by the broadcast channels of the mobile multimedia broadcast system, which pick up IP packet head key information and IP data packet net charge to re-set up data packets.

Description

technical field [0001] The invention belongs to the technical field of mobile multimedia broadcasting or mobile phone television, and in particular relates to a method for transmitting IP data carrying multimedia services in a mobile multimedia broadcasting network. Background technique [0002] Mobile multimedia broadcasting is a broadcasting multimedia transmission and playback technology that has emerged in recent years. Through the hand-held terminal, the media content of the mobile multimedia broadcasting network can be received and played in the case of high-speed movement. The terminal receives the multimedia service program list through the wireless broadcast channel, and can select the channel it has the right to watch, so that it can receive the multimedia data of the selected channel, and realize watching TV on the mobile terminal. [0003] The data transmission of the mobile multimedia broadcasting system is relatively complicated. What kind of data transmission...
