Problems solved by technology

However, if the high-definition streaming media broadcast carried by P2P is played smoothly, in order to reduce the dependence of client nodes on the server, nodes need to share data with each other, and the data interaction between nodes faces the problem of node data integrity

Embodiment Construction

[0039] The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are illustrated.

[0040] figure 1 A schematic diagram showing a P2P streaming media live broadcast system according to an embodiment of the present invention. like figure 1 As shown, the live broadcast system includes an index server (Tracker Server) 11, a content server (Content Server) 12, a compensation server 13 and client nodes (such as figure 1 shown, nodes A, B, C). Among them, the index server 11 is the controller of the P2P live network, and is used to manage the data nodes (client nodes) to which the channel belongs based on the channel; it has received the registration from the client node; and received the data node query request for the channel from the client node, Send a list of data nodes for this channel to the client node. The content server 12 is the provider of the P2P live data source, and i...

Abstract

The invention discloses a method and a system for live broadcast of peer-to-peer (P2P) streaming media. The method comprises the following steps that: the state of a data buffer zone of a live streaming media is monitored; when a data safe zone is not fully filled by the data of the data buffer zone, a client node preferably requests the corresponding live broadcast streaming media data to a compensation server; and when the data safe zone is fully filled by the data of the data buffer zone, the client node requests the corresponding live broadcast streaming media data to an upper node according to a mark of the upper node. In the method and the system, the user node selects the nodes with good network transmission attribute according to a node marking strategy to form a node queue so as to meet a data transmission requirement under a high-definition code stream condition; and through a compensation strategy of the safe zone, safety precaution of data buffering capacity is realized, data intelligent functionalized compensation is actualized and P2P high-definition streaming media live broadcast smooth play is realized.

Description

technical field [0001] The invention relates to the technical field of network streaming media, and in particular, to a method and system for live broadcast of P2P (Peer to Peer, peer-to-peer) network streaming media. Background technique [0002] Streaming media refers to the media format played on the Internet / Intranet by means of streaming transmission. Streaming transmits the entire multimedia content such as audio, video or three-dimensional media through a specific compression method to generate a compressed package, which is transmitted by the media server to the user terminal in real time. The client does not need to download the full media content to play the media. Compared with the simple download method, this streaming transmission method of downloading and playing multimedia files not only greatly shortens the startup delay, but also greatly reduces the system cache capacity requirement, which greatly reduces the user's waiting time. [0003] Streaming media a...
