SMOOTHED REFERENCE PREDICTION FOR IMPROVING SINGLE-LOOP DECODING PERFORMANCE OF H.264/AVC SCALABLE EXTENSION

So-Young Kim, Woo-Jin Han

Abstract

It is well-known that multi-layer extension of H.264/AVC shows good spatial scalability performance mainly due to its efficient inter-layer prediction techniques. Although single-loop decoding is a kind of technique to reduce the decoder-side computational complexity by performing only one motion compensation to decode multi-layer data, its limited use of inter-layer prediction sometimes degrades the performance especially for fast-motion sequences. In this paper, smoothed reference prediction technique is proposed to improve the single-loop decoding performance by replacing base-layer information with current-layer information and simple block-based smoothing function. Experimental results show that the proposed method can improve the coding efficiency with all benefits of single-loop decoding mode. In addition, the proposed method was adopted to scalable extension of H.264/AVC standard Working Draft.
