The coding performance can be further improved when the hierarchical B-picture coding is introduced into H.264/AVC. However, the existing rate control schemes can not work efficiently in such new coding framework. This paper proposes a novel rate control algorithm when hierarchical B-picture coding is used in H.264/AVC. Firstly, a set of scaling-factors applied in designing cascaded quantizer for the B frames at different temporal levels is introduced. Based on the designed scaling-factors, an… CONTINUE READING
