Abstract

To provide spatial, temporal and quality scalabilities, the scalable video coding (SVC) offers several additional techniques. The inter-layer prediction is one of them to improve the coding efficiency. However, it is only applied to the enhancement layer when the base layer is available. Because of this limited inter-layer prediction, it deteriorates the coding efficiency of enhancement layer. In this paper, we propose a new inter-layer prediction scheme for spatial scalability with different frame rates. It improves the coding efficiency using the information of the interpolation layer when the base layer is not available. The experimental results show that the proposed scheme reduces the bitrates by 2~10% and improves video quality by 0.01~0.4dB compared with the reference software, JSVM 11.0.
