Recent Advances In Video Compression

This paper gives an overview over recent advances in video compression and transmission. The new H.263 video compression standard is an important milestone towards wide-spread use of personal video communication. For mobile video applications and video transmission over networks, error robustness and scalability are important issues. Structure-from-motion methods, region-based coding and model-based coding are research topics pointing into the future, towards MPEG-4. 1. INTRODUCTION Digital video compression is one of the key issues in video coding, enabling efficient interchange and distribution of visual information. New applications in the field of communication, multimedia, and digital television broadcasting [1] require highly efficient, robust and flexible digital video compression and encoding techniques[2]. Multimedia applications range for example from desktop videoconferencing and computer-supported cooperative work to interactive entertainment networks where video-on-demand..
