Abstract

Due to its coding efficiency and strong demand for compression technology from the professional video production industry, the JVT recently standardized five new profiles for high quality video - one predictive and the rest intra only. Of these, the new High 4:4:4 Profile sits atop virtually the entire original chain of H.264/AVC profiles (not counting the more recent scalable and multiview coding profiles, which are somewhat specialized), and subsumes the others -- it lacks only the error resilience tools found in Baseline and Extended Profiles. It may thus be regarded as the ultimate codec in the new standard family. While several companies are known to have developed internal technology for this profile, to our knowledge no commercial product has been released to support this profile. In this paper, we present some elements of the first commercial software encoder for the H.264/AVC High 4:4:4 Profile. We make significant progress on realtime performance, using the new Intel i7 processor, while providing some visual performance results on a potential application to infrared sensors, where high dynamic range is critical.
