This paper will present an efficient and scalable coding scheme for video communications. The scheme is capable of encoding and decoding video signals in a hierarchical, multilayer fashion to provide video at differing quality grades. Subsequently, the utilization of this approach to enable efficient bandwidth sharing and robust distribution of video signals in multipoint communications is presented. Coding and distribution architectures are discussed which include multi-party communications in a multi-window fashion within ATM environments. Furthermore, under the limited capabilities typical of wideband/broadband access networks, this architecture accommodates important video-based service applications such as Interactive Distance Learning. |
