Abstract

In this paper, a novel pipelined intra prediction scheme with prediction mode scheduling is proposed to design H.264/AVC video encoder for high-definition TV (HDTV) applications such as HD camcorder. Since the intra prediction of the current 4×4 block cannot be performed before the reconstruction of a previous 4×4 block, intra 4×4 prediction cannot be pipelined for high speed implementation. By rearranging the encoding order of intra 4×4 prediction, the proposed scheme can be pipelined while maintaining consistency with the standard. In order to further increase the hardware utilization, the prediction order of the nine intra 4×4 prediction modes is scheduled depending on the required pixels to generate the predicted images. With the proposed scheme, the intra 4×4 prediction can be pipelined, and the bubble between the blocks can be decreased without the performance degradation. Since the processing time is reduced by up to 41%, it can save the hardware resource. Thus, the proposed scheme can be a good solution for realtime HD sized encoding applications.
