Abstract
With the convergence of IP based multimedia and communications, multipoint
multimedia conferencing is becoming an important form of communication. There are
two major problems that have plagued multimedia conferencing. The first is a form of
control needed over the conference to maintain order and data integrity. The second is to
optimise the bandwidth requirement as network bandwidth generally increase
proportionally to the number of participants within the conference. Both the above
problems place a serious limitation on the number of conference participants. The
control criteria proposed within this the~is was designed to overcome both the above
problems. Based on creating a virtual meeting room, the control criteria was formulated
using these two fundamental principles:
+ The need for a control mechanism to coordinate the conference.
+ Only one site may broadcast or make changes (collaborative document
conferencing) at any one time.
The control criteria proposed in this thesis provides a method that will optimise
multimedia conferencing bandwidth. The implementation of this control criteria is
assisted by the creation of a distributed multimedia conferencing environment, which
uses the distributed network entities architecture. This architecture will enable higher
performance for multimedia conferencing systems as compared with the existing
architectures. The distributed multimedia conferencing environment is composed of four
entities. They are as follows: The server entity, the client entity, the MLIC entity and the
compression entity. This thesis shows that when implementing the distributed
multimedia conferencing architecture together with the control criteria, a unique high
performance low bandwidth multimedia conferencing environment can be created. Such
an environment resolves the problem of control within a conference as well as optimises
the bandwidth requirement for such conferences.
