New Framework for Encoder Optimization of Scalable Video Coding

Abstract

In this paper, a new framework is proposed for the encoder optimization of scalable video coding (SVC). It is used to provide guidelines for the design of rate control and fast mode decision at the base layer and base layer selection at enhancement layer for the SVC. It is also pointed out that the coding technology of inter-layer prediction with two base layers is desired for the combined coarse granular scalability and spatial scalability such that the coding efficiency losses at layers with higher resolution are about 10% when compared to the corresponding single-layer video coding.
