Abstract

A method and apparatus for distributing media over a P2P IPTV network is described. Media frames of a subscribed media channel are received at a peer node in the network. Meta data is sent from selected other peer nodes in the network to the peer node. The meta data includes media channel subscription information of the selected other peer nodes. When user instructions are received to change the subscribed media channel to a new channel, the meta data is used to determine whether any of the selected other peer nodes are subscribed to the new channel. If one of the selected other peer nodes is subscribed to the new channel, frames of the new channel are requested from that peer node.
