CollaboraTV supports interaction between groups of people that watch shows independently. When individuals watch a show, they can generate events, such as text annotations and gestures, which are attached temporally to the media stream. When other users watch the same show at a later point, these events are replayed with the media stream, visualized using small avatars. The system also provides a show-recommendation system.
