Abstract

A novel achievement to optimum bit allocation for H.264/AVC is presented, which is different from JVTO016 by using a simple linear rate instead of the wellknown MPEG-4 Q2 model. To find the global optimum, we resort to Lagrange Optimization technique and develop a close-form formula to the optimum problem. It is shown via extensive experiments that the new rate control (RC) scheme exceeds JVT-G012, the current standardized RC scheme and is comparative to JVT-O016 in coding performance.
