This paper presents a novel scene change detection method using edge direction based on intra prediction mode in H.264/AVC. When scene change occurs, there is less temporal correlation between frames. Therefore, most of macro-blocks are encoded in intra mode. Using this property, the proposed method calculates the percentage of intra mode blocks in each predictive frame in order to get candidates of scene change frames. To find accurate scene changes, we generate an edge histogram of each candidate with eight prediction directions of intra prediction mode in H.264/AVC. We detect scene change frames with l1-norm of edge histograms. The experimental results show that the proposal method is efficient and robust
