H.264/AVC, the result of the collaboration between the ISO/IEC Moving Picture Experts Group and the ITU-T Video Coding Experts Group, is the latest standard for video coding. The goals of this standardization effort were enhanced compression efficiency , network friendly video representation for interactive (video telephony) and non-interactive applications(More)
Standardized hybrid video coding algorithms, e.g., HEVC, apply intra frame prediction or motion compensated prediction and subsequent integer approximated DCT or DST transform coding. The coding efficiency of the transforms depends on the statistical moments and probability distribution of the input signals. For a Gaussian distribution, the DCT always leads(More)
State of the art hybrid video coding algorithms, e.g. H.264 / MPEG-4 AVC [1] and the currently emerging HEVC video coding standard [2], apply block-based prediction and subsequent block-based prediction error coding, which includes quantization. To reduce annoying block artifacts typically resulting from the combination of block-based processing and coarse(More)
Entropy coding is a lossless compression technique which is supported in H.264/AVC standard by different techniques. According to baseline and the extended profiles of H.264/AVC, two variable length techniques are for seen. The first one is context adaptive variable length coding (CAVLC) and the other is exponential Golomb (Exp-Golomb) one. The CAVLC is(More)
