Enhanced On-Line Collaboration System for Broadcast Presentations

摘要

An enhanced on-line collaboration system is provided for subset of users viewing the same broadcast presentation at the same time. Each session is initiated by a single user sending a session request to a collaboration server. The request identifies members of a proposed subset and the broadcast presentation that is to be the subject of the collaboration. The request may also include an initial user collaboration input. The collaboration server establishes a final subset of available users and forwards any user collaboration input to broadcast redistributors associated with members of the final subset. Subsequent collaboration inputs from members of the final subset are forwarded to broadcast redistributors and appear as graphic or text overlays on the broadcast display seen by members of the final subset.
