RD-Optimization of Hierarchical Structured Adaptive Vector Quantization for Video Coding
This paper contains two contributions to very-low-bitrate video coding. First, we show that in contrast to common practice incremental techniques for rate-distortion optimization ...

A Study on the Quantization Scheme in H.264/AVC and Its Application to Rate Control
Compared with previous video coding standards, H.264/AVC employs a division-free quantization scheme. The relation between quantization parameter and quantization step changes from...
