Abstract
The new HEVC standard enables a major advance in compression
relative to its predecessors, and its development was a large collaborative effort that
distilled the collective knowledge of the whole industry and academic community
into a single coherent and extensible design. This topic collects the knowledge
of some of the key people who have been directly involved in developing or
deploying the standard to help the community understand the standard itself and
its implications. A detailed presentation is provided for each of the standard's
fundamental building blocks and how they fit together to make HEVC the powerful
package that it is. The compression performance of the standard is analyzed, and
architectures for its implementation are described. We believe this topic provides
important information for the community to help ensure the broad success of HEVC
as it emerges in a wide range of products and applications. The applications for
HEVC will not only cover the space of the well-known current uses and capabilities
of digital video—they will also include the deployment of new services and the
delivery of enhanced video quality, such as the deployment of ultra-high-definition
television (UHDTV) and video with higher dynamic range, a wider range of
representable color, and greater representation precision than what is typically found
today.

HEVC Background and Development
The standard now known as
High Efficiency Video Coding
(HEVC) [

accumulated experience of about four decades of research and three decades of
international standardization for digital video coding technology. Its development
