In this paper, a novel early mode decision algorithm is proposed to reduce the complexity of the mode selection process for enhancement layers in H.264 Scalable Video Coding. Generally, the proposed algorithm consists of the following three main steps which are applied to the enhancement layer. Firstly all the macroblocks are divided into several cases according the mode of neighboring macroblocks and collocated MBs in the base layer. Then different mode selection algorithms perform for different cases. At last, if it is necessary to check more than one intra mode, a fast intra mode selection algorithm is performed. Experiment results show that with this algorithm, 10%~40% encoding time can be saved with a negligible loss in BDSNR and very little increment in BDBR compared to JSVM 9.18.
