Abstract

Mobile communication channels are time-varying with respect to the available throughput and error conditions. This paper presents a centralised unicast architecture for use in multiparty communications. It is proposed to use object-oriented video coding to implement video prioritisation schemes and experiments are carried out to determine the perceptual quality improvements that can be achieved by varying the allocation of available source and channel protection bits to different video objects. Scene segmentation is also presented as a tool for increasing the throughput efficiency when transmitting encoded videoconferencing scenes
