Performance analysis of inter-layer prediction for H264/SVC

With the introduction of diverse variety of display transmission and resolutions channel capacities, the joint Video Team has developed a new scalable video coding standard (H264/SVC) as an extension of H.264/AVC. In fact, it provides a single compressed bit-stream with several scalability levels. The spatial scalability is mainly based on coding tools such as inter-layer predictions that offer a better coding efficiency. In this paper, we present the impact of different inter layer prediction modes for spatial scalability. As a first step, analysis results show the significant role of inter-layer prediction process for coding efficiency. As a second step, role of each inter-layer prediction type is investigated. Simulations results demonstrate the significance of inter-layer intra prediction and inter-layer residual prediction when targeting a better coding efficiency.
