This paper describes a hybrid motion-compensated wavelet transform coder designed for encoding video at very low bit rates. The coder and its components have been submitted to MPEG-4 to support the functionalities of compression efficiency and scalability. Novel features of this coder are the use of overlapping block motion compensation in combination with a discrete wavelet transform followed by adaptive quantization and zerotree entropy coding, plus rate control. The coder outperforms the VM

He is also very active in the multiview profile ad hoc group in MPEG. His main research interests are compatible/scalable video compression, stereoscopic video coding, and ATM-based digital video application.
