Abstract

This paper presents a new Base Layer coding scheme which introduces the rate-distortion optimization mode decision into hierarchical-fashion B-picture coding with open-loop structure. It can not only achieve high coding performance for Base Layer bit-rate point and meanwhile, but the scheme also keep the strong correlation between Base Layer and Enhancement Layer implemented by 3D subband scalable video codec, because they share the similar lifting based Motion-Compensated Temporal Filtering (MCTF) decomposition structure. In addition, how to exploit the correlation between Base Layer and Enhancement Layer is also investigated. Experimental results show this method improves the coding performance and visual quality at both low and high bit-rate points.
