2.TVU

tvu networks offers a free global live TV service that you can watch on your Windows PC over a broadband Internet connection. This service is dedicated to bringing you TV that you can't get from cable or satellite, such as news and sports from around the world.

The TVU service is accessed with a free downloadable Windows application, the TVUPlayer, which is available here. In the first year of service, the TVUPlayer has already been downloaded over 7 million times.

TVU uses a new broadcast technology called Real-Time Packet Replication. With this technology, all the viewers who are watching a channel at the same time are cooperating to give everyone the best possible signal. TVU's application does not create any new files on your hard disk because you're watching live TV.
Unlike typical Internet video broadcasts that use the older streaming technology, TVU's broadcasters do not need to dedicate more bandwidth for each additional user. This allows broadcasters to reach very large numbers of viewers at low cost. Because TVU can have an unlimited number of channels, TVU offers broadcasters opportunities denied to them by cable and satellite systems. Local broadcasters become global broadcasters; new channels can find a broadcast slot; and bigger broadcasters can create new channels to showcase content that they own but don't have space to broadcast on their existing channels.

Most exciting of all, viewers can become broadcasters using TVU networks' free Broadcast application. This application, combined with a standard-grade PC and a typical broadband Internet connection, allows anybody to become a broadcaster. This basic set-up allows any number of viewers world-wide to watch your channel.
