GROUP-WISE VIDEO CONFERENCING USES 3D-GRAPHICS MODEL OF BROADCAST EVENT

摘要

A TV broadcast service to multiple geographically distributed end users is integrated with a conferencing mode. Upon a certain event in the broadcast, specific groups of end users are switched to a conference mode under software control so that the group is enabled to discuss the event. The conference mode is enhanced by a 3D- graphics model of the video representation of the event that is downloaded to the groups. The end users are capable of interacting with the model to discuss alternatives to the event.
