Abstract
The present invention relates to methods and systems for broadcasting/multicasting of media content over a communication network using shared bandwidth available from peer-to-peer networking. The system may include one or more servers for delivering media content over the network for one or more media content programs. The media content comprises data packets. The one or more servers may provide IP multicasting information and tracking information for the data packets to all receiving devices requesting the media content. Any receiving devices that request the media content and that one of: (a) fail to subscribe to the IP multicasting channel; or (b) fail to receive all of the data packets for the media content over the IP multicasting channel, may use the tracking information to identify other of the receiving devices that have received the data packets and to request the data packets from at least one of the identified receiving devices.
