Peer-to-peer (p2p) streaming Internet TV
All streaming media players buffer segments of audio/video streams before actually showing them. After buffering a segment a media player shows it, and at the same time the media player starts buffering the next segment. Ideally there shouldn't be any sound or video frame freezes.
Unfortunately in reality internet servers and internet channels often get overloaded and users get sound and/or video frame freezes. That is where peer-to-peer (p2p) technology can help. Software like PPLive, PPStream, Coolstreaming, QQLive, SopCast, Feidian, TV Ants allows users to watch streaming media (TV channels) based on BitTorrent (BT) p2p technology.
Because BitTorrent p2p technology is used, every user viewing media with p2p streaming Internet TV software uploads content at the same time the TV programs are downloaded and viewed. Since all viewers upload content when viewing media, everyone becomes a broadcaster (server) without the cost of traditional streaming. And hence, the more users are online, the faster the programs can be loaded. p2p technology also enables a client to automatically find different connection nodes (other users) and download media stream data from the nearest node (the user with the nearest location). The good thing is, stream data is buffered in the memory, not on the hard disk.
p2p streaming Internet TV software creates a stream on localhost and that stream is then read by Windows Media Player, Real Player or other media players.
Since p2p technology relies on sharing, the more media data segments one uploads to other users, the more segments he himself is entitled to download from others. That is why it may take several minutes before the received stream would run continuously. One has to upload to other users at a rate high enough to be able to download segments in a sufficient rate himself. Therefore it is recommended to establish a connection as early as possible before the starting time of a desired event. The more users sharing segments there are the better stream each one of them will get.
