The H.264/AVC video coding standard aims to enable significantly improved compression performance compared to all existing video coding standards. For achieve this purpose, a robust rate-distortion optimization (RDO) [4] technique is employed to select the best coding mode and reference frame for each macro-block. As a result, the complexity and computation load increase drastically. This paper presents a fast mode decision algorithm for H.264/AVC inter-prediction based on frame difference. There used signal to noise ratio (SNR) of 4*4 block information based on adjustable threshold to judge the mode type. Experimental results show that the fast inter-prediction mode decision scheme increases the speed of motion estimation significantly with negligible loss of peak signal-to-noise ratio.
