Rate and resolution scalable subband coding of video
We propose a full colour video compression strategy, based on 3-D subband coding with camera pan compensation, to generate a single, embedded, compressed bit stream supporting multiple decoder display formats and a wide, finely gradated range of bit rates. An experimental implementation of our 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 kilo-bits per second to several mega-bits per second. The 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.<<ETX>>
