Abstract

One of the advantages of H264/AVC video coding standard is its new algorithms in intra coding mode, but making decision among all these prediction modes needs some complex computation so it makes a bottleneck in implementation of a real-time video codec. In this paper a new and simple method for intra prediction mode decision has been proposed and also implemented on a DM648 TI DSP. Experimental results illustrate the proposed algorithm efficiency in coding procedure speed versus neglectable PSNR and bit rate degradation.
