Problems solved by technology

[0007] The P2P live broadcast technology in the prior art slices the streaming media data in the form of each frame and encapsulates them into P2P media data packets for transmission. However, since the data of each frame is different, some frames of media data packets contain The data is large, especially for some users with small bandwidth, the sound or video screen will be stuck when using it.
This situation is very unfavorable in many applications that require high real-time performance, including video conferencing, distance learning, live video, etc., and reduces the system's service quality and user experience.
At the same time, the P2P live broadcast technology in the existing technology does not have a data verification mechanism, which cannot guarantee that the live stream has been tampered with, and data security cannot be guaranteed

Abstract

The invention provides an audio / video live broadcast streaming media data transmission method in a P2P system. The method comprises the following steps of acquiring live broadcast streaming media source data; slicing the live broadcast streaming media source data according to a manner that each frame is used as the length unit and coding the live broadcast streaming media source data for obtaining media data packets; slicing the continuous media data packets according to a fixed length and performing code packaging for obtaining P2P data packets; and transmitting the P2P data packets to a playing client through a P2P network. The audio / video live broadcast streaming media data transmission method in the P2P system has advantages of minimizing network transmission expenditure, reducing requirement to bandwidth, and furthermore effectively ensuring no tampering of the live broadcast flow through a verification mechanism.

Description

technical field [0001] The invention relates to the field of live streaming media data transmission, and in particular to a method for transmitting audio and video live streaming media data in a P2P system. Background technique [0002] With the development of the Internet, it has gradually become a trend to use the Internet for live streaming or on-demand broadcasting, gradually integrating into people's daily life, forming hot spots in various aspects of work, study and entertainment, whether it is video conferencing, online education or Internet TV and video websites are used more and more widely. Streaming media (Stream Media) refers to the media format played on the Internet / Intranet by means of streaming, such as audio, video or multimedia files. Streaming media does not need to download the entire file before playing, only the beginning part of the content is stored in the memory, the data packet is cached in the computer and the streaming media data is output correc...
