A HARDWARE SOLUTION FOR HEVC INTRA PREDICTION LOSSLESS CODING

2015

International audience; The lossless coding mode of the High Efficiency Video Coding (HEVC) main profile that bypasses transform, quantization, and in-loop filters is described. Compared to the HEVC non-lossless coding mode, the HEVC lossless coding mode provides perfect fidelity and an average bit-rate reduction of 3.2%–13.2%. It also significantly outperforms the existing lossless compression solutions, such as JPEG2000 and JPEG-LS for images as well as WinRAR for data archiving. A fully parallel-based solution is presented in this paper in order to reduce processing time and computation complexity resulting from intra prediction. Two higher performance structures are designed to perform …
