Abstract :In this paper we investigate DCT-based embedded zerotree coding of composited videos for multi-point video conferencing. Zerotree coding is a Progressive coding method which encodes a video or image into a bit stream with increasing precision. The embedded property is accomplished that ali encodings of the same image or video at lower bit rates are embedded in the beginning of the bit stream for the target bit rate [9]. By using the embedded zerotree coder, quality of the composited videos is improved when compared to a conventional encoder
Keywords : Video coding, video compositing, multi point video conferencing
