This paper looks at some of the challenges associated with building a coder for video telephony that operates at bit rates below 20 kbps. It then proceeds to present a novel hierarchically structured coder that provides a mechanism for addressing many of these difficulties. The hierarchical structure employs several different simple predictors that are ordered according to their coding gains. This structure is contrasted with traditional predictive coders for video head and shoulders sequences and its performance is demonstrated with several examples.
