P2P - (Peer-to-Peer) - (in terms of Interactive TV) - (May known as Box-to-box Networking) - (1) When a business’ product/service can only communicate with users of that specific business' product/service. For instance, peer-to-peer video-casting might only be possible between one business' DVR (for instance Sky's) subscribers and not between Echostar's and Sky's DVR subscribers. (2) Networks where their hosts interact with each other on an equal basis, particularly in the exchange of data. These networks use the computing power and bandwidth of those participating in the network rather than using a comparatively low number of servers.

Peer-to-peer networks are generally simpler than client/server architectures, but often don't perform as well under heavy loads. P2P networks are also used for instant messaging.
