Peer to Peer TV

Peer to Peer Television - P2PTV

peer to peer structureThere are several definitions about peer to peer network structure, many of them (if not all) talk only about the dark side of it. A peer to peer network is and should be, more than illegal transfer of copies of software, movies, music, etc.

In a pure peer to peer structure every user connected to the network becomes a broadcaster by sharing his/her own resources and bandwidth with other connected users, this kind of service works better when more users are online, (the more the better), on the contrary, conventional server based streams work better with less users connected at the same time (the less the better).

P2P is also a way to share resources to reach a common goal (in our case P2P TV), obviously when the channel broadcasted is Free to Air, in other words, the channel is freely available (not encrypted) and it can be tuned in using a conventional TV set or decoded by an untempered satellite receiver. There are, however, copyrights and intelectual properties that should be considered before you join a P2P network.

TV producers are looking at this technology as a mean to offer their content online with low costs; remember that internet streaming providers charge by consumed bandwidth or simultaneous number of users connected at the same time or a combination of both. P2P TV will help to reduce those costs dramatically because every user watching the stream is at the same time sharing his/her own resources making it cheaper and (at less theorically) illimited.

Pros

  • Broadcasting p2p TV is cheaper than conventional alternatives
  • Bigger number of simultaneous users with less resources

Contras

  • No one can guarantee a reliable stream, because every user is a rebroadcaster, nodes with dialup conections or slow computers can affect negatively speed and quality making the whole system less reliable, same case if an uplink or downlik point become saturated or unstable.
  • Broadcasters have less control over the stream, such as number of viewers, regions where it is available and statistics. In order to diminish the impact of this issue, broadcasters are using a hybrid solution, with several servers acting as nodes, loading balancers, redirecting users as required and controling access to streams.
