During an Interactive Multicast, identical transmissions, which comprise the floor (video
streams, audio streams, and data packets) are sent from one party to multiple parties. The
initiating party ( Chair ) calls one or more contacts ( Participants ) at the start of the conference
and controls its progression. Contacts may also join an open Multicast by calling the Chair.
The Chair can grant and reclaim the floor, clear floor requests and disconnect the session. A
Participant may receive the floor, in which its video and audio is seen and heard,
respectively, by the other Participants and the Chair for a period of time.
Only Collaborate Desktop system supports Interactive Multicasts over a Local Area Network
(LAN), in which the Chair and all Participants may be seen and heard during the duration of
the meeting. Collaborate Desktop provides both Chair and Participant functions.
Interactive Multicasts can proceed in the form of a lecture or demonstration, in which
Participants’ participation is restricted and controlled by the Chair, or as a free discussion, in
which the main Participants can interact freely without the need to receive permission from
the Chair. Additionally, these sessions may be public Multicasts , in which non-participating
audience members can view the events from their desktops or conference rooms.
NOTE: Interactive Multicasts are available only over local area networks
(LANs) that conform to H.323-based recommendations. Therefore, all
parties must have a LAN (IP) connection.
