摘要
Mode-dependent rate and distortion estimation methods for coarse grain scalability (CGS) in scalable video coding (SVC) are provided. The rate and distortion values of a base layer and an enhancement layer are estimated based on different combinations of a block partition size of the base layer block, a transform block size of the base layer transform, and a quantization parameter of the base layer quantization as well as a block partition size of the enhancement layer block, a transform block size of the enhancement layer transform, a quantization parameter of the enhancement layer, and a setting of the inter-prediction, and a mode pair for CGS in SVC may be selected accordingly based on the estimation of the rate and distortion values of the base layer and the enhancement layer. The disclosure also provides a mode-dependent rate and distortion estimation apparatus to realize the above method.
