An adapted prediction algorithm for H.264 is proposed in this paper. For I frames, a new intra algorithm is proposed in which a novel Intra_4×4 mode selection method is designed. Nine Intra_4×4 modes are divided into three classes, the suitable mode class for current 4×4-block is predicted using the mode classes of neighboring left and up blocks. For inter frames, a new inter prediction algorithm is proposed, and two matrixes which are composed of sum of absolute values of the integer transform coefficients in 4×4-residual-block contained in luminance 16×16-block and 8×8-block are defined respectively, the novel MB and sub-MB mode selection criteria which use the derived gradients of the two matrixes are then proposed.
