Abstract
Proposes a full colour video compression strategy, based on 3D subband coding with camera pan compensation, to generate a single embedded bit stream supporting multiple decoder display formats and a wide, finely gradated range of bit rates. An experimental implementation of the algorithm produces a single bit stream, from which suitable subsets are extracted to be compatible with many useful decoder frame sizes and frame rates and to satisfy transmission bandwidth constraints ranging from several tens of kilobits per second to several megabits per second. Reconstructed video quality from any of these bit stream subsets is often found to exceed that obtained from an MPEG-1 implementation, operated with equivalent bit rate constraints, in both perceptual quality and mean squared error. In addition, when restricted to two dimensions, the algorithm produces some of the best results available in still image compression. >
