Embodiment Construction

[0027] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0028] Referring to FIG. 1 , it is a schematic flow block diagram of a method for implementing error isolation when transmitting mobile multimedia broadcast media data according to an embodiment of the present invention. The specific process is as follows:

[0029] Step 110: Divide the media data into multiple independent media data units at the sending end;

[0030] Step 120: Record the length information of each media data unit in the header information of the media data;

[0031] Step 130: adding a synchronization code between each media data unit to separate;

[0032] Step 140: Send the media data including the packet header information, each media data unit, and the synchronization code between the media data units to the receiving terminal.

[0033] Referring to FIG. 2 , it is a schematic diagram of video data error isolation in a method for implementing err...

Abstract

The method comprises: 1) at sending end, segmenting multimedia data into multi independent media data units; 2) recording the length information about each media data unit in the header information of the media data; 3) adding syn code between each media data unit to separate the multimedia data unit; 4) sending the header information, the media data units and the syn codes between the media data units to the receiving end. By the invention, after terminal receives the media data, even in the case of appearing error code, the error cannot be spread due to the correct segmentation of different data blocks.

Description

technical field [0001] The invention relates to the technical field of mobile multimedia broadcasting or mobile phone television, in particular to a method for realizing error isolation when transmitting mobile multimedia broadcasting media data, which is applicable to mobile broadcasting networks. Background technique [0002] Mobile multimedia broadcasting is a multimedia playback technology that has emerged in recent years. With a handheld terminal, you can watch TV while moving at high speed. The terminal receives the program list through the wireless protocol, 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 air data transmitted by the system is divided into different channels and transmitted separately through the multiplexing technology. The terminal can receive the relevant data, and realize the normal broadcasting of the TV through t...
