AB This article proposes a new focus of research for multimediaconferencing systems which allows a participantto flexibly select another participant or a group formedia transmission. For example, in a traditional conferencesystem, participants voices might by default beshared with all others, but one might want to select asubset of the conference members to send his/her mediato or receive media from. We review the concept ofnarrowcasting, a model for limiting such informationstreams in a multimedia conference, and describe a designto use existing standard protocols (SIP and SDP)for controlling fine-grained narrowcasting sessions.
