Fast adaptive early termination for mode selection in H.264 scalable video coding

In the scalable video coding extension of the H.264/AVC standard, an additional inter-layer prediction is combined with the traditional inter-frame prediction and intra prediction to obtain coding efficiency. This additional prediction demands a higher video encoding computational complexity. In this paper, our previously developed fast adaptive early termination algorithm is utilized to speed up the mode selection component of the H.264 scalable video coding at the base and enhancement layers. The experimental results over different content video sequences show a time reduction by 20% to 50% for spatial and quality scalable situations as compared with JSVM9.8 while achieving more or less the same video quality.
