Abstract

See full text

The emerging High Efficiency Video Coding (HEVC) standard achieves significant performance improvement over H.264/AVC standard at a cost of much higher complexity. An H.264/AVC to HEVC transcoder is described for multi-core processors implementing Wavefront Parallel Processing (WPP) and SIMD acceleration, along with expedited motion estimation (ME) and mode decision (MD) by utilizing information extracted from the input H.264/AVC stream. Experiments using standard HEVC test bitstreams show that the described transcoder may achieve a 70× speed up over the HEVC HM S.1 reference software (including H.264 encoding) at very small rate distortion (RD) performance loss.
