This paper presents an improved update operator for H.264 scalable extension, which is a new joint standardization effort of ISO/IEC and ITU-T. Energy Distributed Update (EDU) [1] is utilized to reduce decoder complexity. The relationship between EDU and the optimum update in [2] is revealed. Moreover, for the constrained motion-compensated lifting structure employed in H.264 scalable extension, we derive a set of new update coefficients to improve coding performance based on distortion
