In order to reduce the high coding complexity in H.264/AVC,this paper proposes an improved direction detection mode selection algorithm to improve the encoding efficiency.The proposed algorithm takes advantage of the correlation in temporal and spatial domain and simplifies the DC mode.Experimental result shows that the proposed method can reduce the encoding time by 70% with negligible coding loss,and it reduces the Rate Distortion Optimization(RDO) calculations.
