It investigates linearly combined motion comp sated signals and generalizes the well known superposition for bidirectional prediction in B pictures. The number of superimposed signals and the sel tion of reference pictures will be important aspects of the discussion. The application oriented part of the book employs this concept to the well known ITU T Recommendation H.263 and continues with the improvements by superimposed motion compensated signals for the emerging ITU T R ommendation H.264 and ISO IEC MPEG 4 (Part 10). In addition it discusses a new approach for wavelet based video coding. This technology is currently investigated by MPEG to develop a new video compression standard for the mid term future.
