Abstract

Temporal scalability with dyadic temporal enhancement layers can be very efficiently provided with the concept of hierarchical B frames. In this paper, extensive experiments are carried out to investigate the influence of different bit allocation schemes to the performance of the dyadic hierarchical coding structure with hierarchical B frames. The bit allocation schemes are realized by quantization and rate- distortion optimization. Based on analysis of the experimental results, conclusions are derived with respect to the selections of the quantization step and Lagrange multipliers, respectively, which serve as solid bases for the design of the encoders employing hierarchical B frames to provide temporal scalability.
