IPTV PRESENCE AND INTERACTION PROTOCOL

摘要

Disclosed are techniques for a protocol that provides for a TV viewing experience with interaction by allowing for social collaboration of non co-located TV viewers and integrating the TV viewing experience with social networking concepts and interactive multimedia communication. The protocol enables a digital video distribution system (e.g., IPTV) to provide a user with presence, channel, and grouping information regarding other users in the IPTV system and available video content. The protocol also enables users of the IPTV system to interact using real- time and/or non-real time communication.
