Paper Abstract

A layered Pyramid image coding scheme suitable for interworking of videoconferencing and videophone services is presented in this paper. The scheme proposed takes advantage of inter-layer embedded motion prediction to compress image data on the upper Pyramid enhancement layer. As an important advantage of this scheme we have preserved independence of the coding in the two layers using embedded motion compensation. Thus no information about the coding procedure on the lower resolution layer is needed to encode the upper layer enhancement information. The results are encouraging, showing that the scheme reconstructs images of both CIF and QCIF resolution with good quality and that the scheme is more data efficient than a comparable Simulcast approach.
