Title
Bit allocation for quality scalability coding of H.264/SVC
Abstract
An efficient model-based bit allocation algorithm, in this paper, is proposed for quality scalability coding of H.264/scalable video coding (SVC). The conventional Rate-Distortion models are not available for quality scalability coding of H.264/SVC. To overcome this issue, the relationship between the percentage of header bits and quantization parameter is investigated to obtain an accurate single layer rate model. Moreover, MGS/CGS inter-layer MAD affine relationship is employed to extend the Rate-Distortion models from the base layer (BL) to the enhancement layer (EL). Finally the Lagrange solution of the bit allocation problem is worked out. Experimental results show that the proposed bit allocation algorithm outperforms Joint Scalable Video Model (JSVM) software algorithm.
