“…Some of those techniques were based on improved versions of CAVLC or CABAC, others were using alternative methods of statistical coding, such as V2V (variable-to-variable) codes [34] or PIPE (probability interval partitioning entropy) codes [53,52,102], and a third category introduced increased capabilities for parallel processing on a bin level [85], syntax element level [91,92], or slice level [105,33,29]. In addition, improved techniques for coding of transform coefficients, such as zero-tree representations [7], alternate scanning schemes [41], or template-based context models [61,102], were proposed.…”

Context-Based Adaptive Binary Arithmetic Coding (CABAC) is a method of entropy coding first introduced in H.264/AVC and now used in the latest High Efficiency Video Coding (HEVC) standard. While it provides high coding efficiency, the data dependencies in H.264/AVC CABAC make it challenging to parallelize and thus limit its throughput. Accordingly, during the standardization of entropy coding for HEVC, both aspects of coding efficiency and throughput were considered. This chapter describes the functionality and design methodology behind CABAC entropy coding in HEVC.

“…Corresponding to the macroblock scanning in H.264/AVC, LCUs are encoded in a raster scan order. Each LCU is subdivided into smaller Coding Units (CU) according to a quadtree structure [8] [9]. This subdivision can recursively continue until the smallest CU size of 8x8 is obtained.…”

Abstract-Scalable video coding performance largely depends on the underlying single layer coding efficiency. In this paper, the quality scalability capabilities are evaluated on a base of the new High Efficiency Video Coding (HEVC) standard under development. To enable the evaluation, a multi-loop codec has been designed using HEVC. Adaptive inter-layer prediction is realized by including the lower layer in the reference list of the enhancement layer. As a result, adaptive scalability on frame level and on prediction unit level is accomplished. Compared to single layer coding, 19.4% Bjøntegaard Delta bitrate increase is measured over approximately a 30dB to 40dB PSNR range. When compared to simulcast, 20.6% bitrate reduction can be achieved. Under equivalent conditions, the presented technique achieves 43.8% bitrate reduction over Coarse Grain Scalability of the SVC -H.264/AVC-based standard.

“…As such, they are well suitable for use in future video coding applications. Described transforms have been proposed to ITU-T SG16 Q6 (VCEG) standardization committee, 21 and were also included in Qualcomm's response to JCT-VC call for proposals 22 . This paper is organized as follows.…”

This paper describes design of transforms for extended block sizes for video coding. The proposed transforms are orthogonal integer transforms, based on a simple recursive factorization structure, and allow very compact and efficient implementations. We discuss techniques used for finding integer and scale factors in these transforms, and describe our final design. We evaluate efficiency of our proposed transforms in VCEG's H.265/JMKTA framework, and show that they achieve nearly identical performance compared to much more complex transforms in the current test model.
