Improvement of Inter-Layer Motion Prediction in Scalable Video Coding

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 proposed method enhances coding efficiency without increasing the computational complexity of the decoder. key words: MPEG-4 AVC, H.264, scalable video coding, inter-layer prediction, fine granular scalability, FGS motion refinement
