Abstract :
This paper describes experimental study of Quality of Experience of compressed audiovisual materials for bandwidth-limited multimedia systems. A new method of bit rate reduction in such systems is proposed in this paper. It is based on a cross-modal audiovisual interaction-based model of Quality of Experience and takes into account that optimal audio and video codec parameters in bandwidth-limited multimedia systems can be content-adaptive.
