High Efficiency Video Coding (HEVC): Algorithms and by Vivienne Sze

By Vivienne Sze

This publication presents builders, engineers, researchers and scholars with unique wisdom concerning the excessive potency Video Coding (HEVC) common. HEVC is the successor to the generally winning H.264/AVC video compression regular, and it presents round two times as a lot compression as H.264/AVC for a similar point of caliber. The purposes for HEVC won't simply hide the distance of the well known present makes use of and functions of electronic video – they are going to additionally contain the deployment of recent companies and the supply of superior video caliber, reminiscent of ultra-high-definition tv (UHDTV) and video with greater dynamic variety, wider diversity of representable colour, and larger illustration precision than what's commonly came across this day. HEVC is the following significant iteration of video coding layout – a versatile, trustworthy and powerful resolution that might help the subsequent decade of video functions and simplicity the weight of video on world-wide community site visitors. This booklet presents an in depth rationalization of many of the elements of the normal, perception into the way it used to be built, and in-depth dialogue of algorithms and architectures for its implementation.

Example text

The key elements of the HEVC design relevant to the systems interfaces are the NAL unit design, parameter sets, and SEI messages. The main systems standards of interest are Realtime Transport Protocol (RTP) [11], MPEG-2 systems [3, 4], and ISO Base Media File Format (ISOBMFF) [5]. Many other systems and application specifications build upon these three standards. For example, several file format specifications and Dynamic Adaptive Streaming over HTTP (DASH) [6] are based upon ISOBMFF, most broadcast standards use MPEG-2 systems, and most IP videoconferencing applications use RTP.

The remaining parameters describe coding tools used in the slices which refer to the PPS. Coding tools are enabled or disabled, including dependent slices, sign data hiding, constrained intra prediction, weighted prediction, trans/quant bypass, tiles, and reference list modification. Coding tool parameters signaled in the PPS include the number of reference indices, initial quantization parameter (QP), and chroma QP offsets. g. deblocking filter controls, tile configurations, and scaling list data.

If this referencing structure was allowed and random access was made at the CRA picture, the missing P1 picture would cause uneven output. The third constraint is that all RASL pictures must precede any RADL picture in output order.
