Paper Abstract

Leaky prediction layered video coding (LPLC) partially includes the enhancement layer in the motion compensated prediction loop, by using a leaky factor between 0 and 1, to balance the coding efficiency and error resilience performance. In this paper, rate distortion functions are derived for LPLC from rate distortion theory. Closed form expressions are obtained for two scenarios of LPLC, one where the enhancement layer stays intact and the other where the enhancement layer suffers from data rate truncation. The rate distortion performance of LPLC is then evaluated with respect to different choices of the leaky factor, demonstrating that the theoretical analysis well conforms with the operational results.
