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 scala...
In this paper, a fine granularity SNR scalable video coding scheme is presented. Targeted for low delay applications requiring high coding efficiency, temporal prediction is incorporated into the FGS layer of closedloop P frames with the prediction formed adaptively from enhancement layer and base layer references. This generally requires motion compensation at both enhancement layer and base l...
In this letter, we propose an enhanced method for interlayer motion prediction in scalable video coding (SVC). For inter-layer motion prediction, the use of refined motion data in the Fine Granular Scalability (FGS) layer is proposed instead of the conventional use of motion data in the base quality layer to reduce the inter-layer redundancy efficiently. Experimental results show that the propo...
A flexible and effective macroblock-based framework for hybrid spatial and fine-grain SNR scalable video coding is proposed in this paper. In the proposed framework, the base layer is of low resolution and is generally encoded at low bit rates with traditional prediction based coding schemes. Two enhancement layers, i.e., the low-resolution enhancement layer and the high-resolution enhancement ...
