infrastructure network environments. The emphasis is on jointly-optimised or co-operative 
behaviour between the delivery context, as in real-time network conditions, and the video/audio 
encoder rate control mechanisms. Innovative solutions are sought to enhance the Internet video 
experience in a developing world context where bandwidth is a scarce resource. 
Current research within the group is concentrating on optimal and weighted context-based bit 
allocation techniques and implementations within international standard video codecs. A scalable 
and bandwidth adaptive multimedia broadcasting platform is under development to encompass the 
novelty of the bit allocation research.
