Embodiment Construction

[0092] The present invention discloses an implementation example of a mechanism for recording live streaming content in a peer-to-peer network. This mechanism not only considers how to maintain the load balance of network bandwidth, but also provides a distributed management method to reduce resource consumption in the peer-to-peer network, such as the purchase of servers or the increase of storage space.

[0093] image 3 It is a schematic diagram of an example of a video and audio stream based on a distributed hash table-network (DHT-Network), which is consistent with some implementation examples disclosed in the present invention. image 3 In the example of , taking five nodes (Peer) as an example, the five circles represent nodes 1 to 5. The five nodes use the same hash function to join in the same real-time streaming channel to form a DHT- Network 300, wherein the arrows represent video and audio streams. Media streams to each node from a source end (source) 310. The sha...

Abstract

A P2P network has a content provider and a plurality of peers viewing the same video streaming channel. Each peer has a P2P live streaming system. In an exemplary system, a token manager module manages at least a token sent by the plurality of peer nodes, notifies a recording manager module to publish recorded media stream content, and to record media stream data. The recording manager module, according to the notification, manages a corresponding buffer for each peer node itself, records the media stream content into the corresponding buffer and publishes the recorded media stream content information to the P2P network. A P2P module handles the P2P messages and maintains the P2P network topology for the plurality of peer nodes.

Description

technical field [0001] The technical field of the present invention relates to a peer-to-peer (PEER-to-PEER, P2P) real-time streaming system and method. Background technique [0002] Nowadays, the network bandwidth is increasing day by day, and the quality of media streaming is relatively improved, so the bandwidth usage of the media server is also increased. In order to reduce the bandwidth burden of the media server, many software also start to use P2P technology is the development direction, common forms such as BitTorrent (BT) or mesh network. [0003] For example, in a patent publication (US20070130597) on instant replay and time-shifted playback (playback), a multimedia content delivery server is provided to store all real-time video streams (live video stream), in order to provide real-time playback (instant replay) function, like time-shifted (time-shifted), you can play back the previous screen at any time, and through a central control mechanism, the terminal is c...
