Abstract
Multimedia conference systems are classified into the tightly coupled conference and the loosely-coupled conference, the former is a peer-to-peer-conference or multi-point-conference based un the ITU-T H.323 standard, and the latter is the H.332 standard extended from the ITU-T H.323 standard. Loosely-coupled conference based on the H.332 standard is composed of small participants with the capacity of the send-receive mode and large participants with the capacity of the receive-only mode. In the H.332 conference, a subject and a media type of the multimedia conference is pre-announced for conquest of the difficulty of capability negotiation, and used SDP of IETF for that. Therefore, the H.332-conference can conquer a defect of the H.323 multimedia conference scalability. This paper analyzes H.332 standard for the loosely-coupled conference and describes an implementation of the H.332 multimedia conference systems.
