Problems solved by technology

[0004] In the process of realizing the present invention, the inventor found that there are at least the following problems in the prior art: when the RTP packet is directly packaged by the H.264 elementary stream, when the synchronization information is lost, the phenomenon of data loss and bit error will be caused
The TS (Transport Stream, transport stream) format can recover data information when the synchronization information is lost, but when the H...

Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0025] In order to improve the user's viewing experience of H.264 streaming media, the embodiment of the present invention provides a streaming media transmission method, such as figure 1 shown, including:

[0026] 101. Acquire data frames sequentially from the H.264 data stream;

[0027] For example, when the H.264 data stream is received, the H.264 data stream may be stored in units of frames, and the stored data frames of the H.264 data stream may be sequential...

Abstract

The embodiment of the invention provides a method and a device for transmitting stream media and relates to the field of communication technology. The invention provides the technical scheme for improving the acceptance experience of users for H.264 steam media as follows: obtaining data frames from the H. 264 data stream in turn; packing and converting the obtained data frames into a PES (photoelectric scanner) packet; converting the PES packet into a TS (transport stream) packet, and inserting PCR (program control register) information and PSI (program special information) data in the TS packet according to the frame rates of the data frames; converting the TS packet into a RTP (real-time transport protocol) packet; and transmitting the RTP packet according to a RTCP (time transport control protocol) message transmitted by a client. The method and the device are suitable for multimedia transmission in a 3G (The Third Generation Telecommunication) network.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a streaming media transmission method and device. Background technique [0002] 3G technology can better realize image, music, video and other media information, and provide real-time monitoring, video call, mobile TV and other functions using streaming media transmission technology. The video compression standard H.264 has become the mainstream standard for streaming media transmission due to its high compression rate, high quality, and low bit rate. [0003] At present, the prior art provides a method for transmitting H.264 streaming media based on RTP / RTCP (Real-time Transport Protocol / RTP Control Protocol, real-time transmission / control protocol), which analyzes the network status according to the feedback information of the client, and According to the analysis results, adjust and control the transmission of RTP packets converted directly from H.264 elementary...
