Abstract

Personal and professional multimedia communications is a major growth area in engineering today. The convergence of telecommunications, information processing and multimedia is of strategic importance worldwide and will enable both professional and personal users to have access to extensive on-line communication and entertainment services. However, before multimedia applications can be truly successful, a number of technologically demanding problems must be resolved. For example, future services will need to be delivered at a range of bit rates, dependent on network and channel characteristics, platform type, application and material content. End to end provision of multimedia information across network components of varying capability and performance will therefore impose the need for coding regimes which are inherently scalable and robust to different forms of loss and error.

This lecture will focus on one of the most challenging coding problems- associated with the delivery real time video. It will explain the concepts of image and video compression and explore the above issues in the context of emerging wireless communication networks.
