Embodiment Construction

[0027] The present invention is further illustrated below by means of examples, but the present invention is not limited to the scope of the examples.

[0028] Such as figure 1 As shown, the P2P live broadcast system of the present invention includes an HTTP server 1, an HLS parsing server 2 and a player 3, wherein the number of the player 3 can be many, and can be set according to actual conditions;

[0029] The local installation of the player 3 has a live broadcast processing program (SDK), and the live broadcast processing program is used to start an HTTP daemon process locally, such as http: / / 127.0.0.1:xxx / ;

[0030] In the present invention, the live broadcast processing program is used to obtain video data from the HTTP server 1, and obtain the corresponding m3u8 list file from the HLS parsing server 2;

[0031] The live broadcast processing program is also used to generate 2 very short first file fragments during the P2P live broadcast, and insert the 2 first file fra...

Abstract

The invention discloses a P2P (peer to peer) live broadcasting system and a P2P live broadcasting method. The P2P live broadcasting system comprises an HTTP (hyper text transport protocol) server, an HLS (HTTP live streaming) resolution server and a playing end, wherein a live broadcasting processing program is installed in the playing end, and starts an http daemon process in a local position; the live broadcasting processing program obtains video data from the HTTP server, and obtains an m3u8 list file from the HLS resolution server; the live broadcasting processing program generates a plurality of first file fragments in the local position and inserts the first file fragments to a position before the current video file fragment to be played of the m3u8 list file so that the m3u8 list file can be modified in the local position; the playing end requests and obtains the modified m3u8 list file from the http daemon process in the P2P live broadcasting process, and requests and obtains a plurality of first file fragments and current video file fragments to be played for playing from the http daemon process after the resolution. The system and the method provided by the invention have the advantages that the playing starting speed can be accelerated; the delay can be reduced.

Description

technical field [0001] The present invention relates to a kind of P2P (Peer to Peer, peer-to-peer network) live broadcast technical field, particularly relate to a kind of in HLS (HTTP Live Streaming, the streaming media transmission protocol based on HTTP that Apple Inc. realizes) to accelerate the start-up speed and reduce A delayed P2P live broadcast system and a P2P live broadcast method. Background technique [0002] HLS is a streaming media transmission protocol based on HTTP (HyperText Transfer Protocol, Hypertext Transfer Protocol) implemented by Apple Inc., which can realize live broadcast and on-demand streaming media, and is mainly used in mobile terminals such as iPhone, iPod, iTouch and iPad. [0003] For live broadcasting, its working principle is to divide the live stream into TS media files, and generate m3u8 index files at the same time, and the player downloads each media file in sequence according to the order of m3u8 index files for playback. [0004] Th...
