Embodiment Construction

[0014] The invention utilizes the principle of BT (Bit-Torrent) downloading to construct a set of novel video and audio stream release system based on BT downloading network. To put it simply, in this video and audio distribution system, the video and audio stream data within a certain period of time replaces the file data in the usual BT download. The video and audio stream data contains video information and related audio information, and other customers The end, as a Peer (transmission point), requests video and audio stream data from the video and audio source node and other peers, and buffers them for local playback. This video and audio stream release system based on P2P (peer to peer, point-to-point) technology fully utilizes the characteristics of the BT download protocol and makes full use of the data redundancy between nodes, so that each node can get data from other different nodes. The video and audio data that they need, thus realizing the release of large-scale v...

Abstract

The invention discloses a method for realizing network voice and video communication. First, a peer-to-peer network is constructed; each user in the network is regarded as a node in the peer-to-peer network, wherein each user queries the tracker server for the current ownership of pending The user list of the transmitted video and audio streams; then search according to the obtained user list, and then sequentially receive the segmented and packaged video and audio stream data from other nodes, or sequentially send video and audio stream data to other nodes. Bag. The present invention is simple to operate, easy to implement, fully taps the potential of network transmission, and can realize large-scale network voice and video conference under the condition of occupying less network resources, with timely data transmission and smooth voice and video playback.

Description

technical field [0001] The invention relates to a communication method, in particular to a method for realizing voice and video communication using a network. Background technique [0002] The combination of the Internet and voice and video technology not only needs to satisfy two people's face-to-face communication, but also needs to be able to realize the voice and video multi-party communication function of 10 to 100 people, or even 300 or more people. Traditional large-scale chat rooms are implemented based on a C / S (Client / Server, client / server) structure. Due to the limitation of network bandwidth, the Internet-based voice and video transmission technology is temporarily unable to meet the requirements of this type of real-time video and audio transmission system. Taking the large-scale video conferencing system supporting 100 people as an example, it is currently implemented based on the C / S structure, and the network bandwidth occupied by the compressed video and au...
