Fast H.264/AVC Intra Mode Decision Implementation on DM648 DSP

Abstract

Abstract—One of the advantages of H264/AVC videocoding standard is its new algorithms in intra codingmode, but making decision among all these predictionmodes needs some complex computation so it makes abottleneck in implementation of a real-time video codec.In this paper a new and simple method for intraprediction mode decision has been proposed and alsoimplemented on a DM648 TI DSP. Experimental resultsillustrate the proposed algorithm efficiency in codingprocedure speed versus neglectable PSNR and bit ratedegradation.
