In high-efficiency coding (HEVC), the random-access structure (RAS) is employed due to its high coding efficiency and “random-access” performance. Pictures in RAS are assigned to different temporal layers. And how to select the QP for each temporal layer in quantization parameter cascading (QPC) technique is critical for improving the coding efficiency of… CONTINUE READING
