This study focus on the quantization parameter, namely rate-quantization (R-Q) functions and distortion-quantization (D-Q) functions. Together, these functions allow a better understanding of the rate-distortion (RD) behaviour of an H.264 video codec, which is the key issue of optimum bit allocation. Initial results are presented and discussed.engRate-Distortion optimizationSSIMvideo qualityH.264book part10.1007/978-3-642-02472-6_27
