Abstract

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) is utilized to reduce decoder complexity. The relationship between EDU and the optimum update in B. Girod et al., (2005) 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 analysis. Experimental results show that the proposed update operator can improve coding efficiency with less complexity and meanwhile, frame-wise quality fluctuation is also reduced
