英文摘要	We investigate dependent rate/distortion (R/D) modeling techniques for H.264/SVC videos. We introduce a self-domain (S-domain) analysis method for characterizing the dependent R/D behaviors, where the R/D characteristics of a base layer are employed as the observation domain for those of dependent layers. Based on S-domain observations, we propose empirical dependent R/D models and analyze physical implications of the proposed models. As an application of the proposed R/D models, we examine a joint temporal-quality layer bit allocation algorithm formulated as a Lagrange optimization problem. The proposed R/D models enable us to derive an analytical solution to the joint optimization problem. Finally, it is demonstrated by experimental results that our bit allocation algorithm outperforms JSVM benchmark by a significant margin (10%-20%) at various bit rates.; Engineering, Electrical & Electronic; SCI(E); EI; 0; ARTICLE; 6; 1003-1015; 23
