One-pass multi-layer rate-distortion optimization for quality scalable video coding
In this paper, a one-pass multi-layer rate-distortion optimization algorithm is proposed for quality scalable video coding. To improve the overall coding efficiency, the MB mode in the base layer is selected not only based on its rate-distortion performance relative to this layer but also according to its impact on the enhancement layer. Moreover, the optimization module for residues is also improved to benefit inter-layer prediction. Simulations show that the proposed algorithm outperforms the most recent SVC reference software. For eight test sequences, a gain of 0.35 dB on average and 0.75 dB at maximum is achieved at a cost of less than 8% increase of the total coding time.
