Abstract
The impressive coding efficiency of H.264-AVC comes at the expense of significantly increased algorithm complexity compared to existing standards, which has limited the availability of cost-effective, high-performance solutions. We present a design overview and implementation details of the compliant code optimized for the Intel® Pentium®4 Pentium®M and Xscale™ microarchitectures, including results for encoder rate-distortion performance and encoder/decoder execution speed on the above processors. These results demonstrate that high-quality, real-time H.264/AVC recording and playback are achievable on today's PC (desktop and notebook) platforms and that real-time playback on handheld (mobile phone/portable media player) platforms can also be achieved, with both implemented as optimized software for these general-purpose processor architectures.
