IEEE TRANSACTIONS ON CIRCUITS AND SYSTEMS FOR VIDEO TECHNOLOGY, VOL. 22, NO. 12, DECEMBER 2012
Background (2012)
HEVC is currently being prepared as the newest video coding standard of the ITU-T Video Coding Experts Group and the ISO/IEC Moving Picture Experts Group.
因此下文的語境，是2012年標準尚未確定時。
Abstract
The main goal of the HEVC standardization effort is to enable significantly improved compression performance relative to existing standards --in the range of 50% bit-rate redunction for equal perceptual video quality.
HEVC標準化的主要目的，在於提高壓縮效率——和現有標準相比，在保持感知視頻質量不變的情況下，減小最多50%的比特率。
Ⅰ. INTRODUCTION
HEVC的別名
In ISO/IEC, the HEVC standard will become MPEG-H Part 2 (ISO/IEC 23008-2) and in ITU-T it is likely to become ITU-T Recommendation H.265.
HEVC被ITU-T組織命名為H.265，被ISO/IEC組織命名為MPEG-H Part 2。
WIKIPEDIA: High Efficiency Video Coding (HEVC), also known as H.265 and MPEG-H Part 2, is a video compression standard, one of several potential successors to the widely used AVC (H.264 or MPEG-4 Part 10).
關於ITU-T和ISO這兩大標準制定組織的補充：
Video coding standards have evolved primarily through the development of the well-known ITU-T and ISO/IEC standards.
The ITU-T produced H.261 [2] and H.263 [3], ISO/IEC produced MPEG-1 [4] and MPEG-4 Visual [5], and the two organizations jointly produced the H.262/MPEG-2 Video [6] and H.264/MPEG-4 Advanced Video Coding (AVC) [7] standards.
關於HEVC的前任：AVC
The major video coding standard directly preceding the HEVC project was H.264/MPEG-4 AVC, which was initially developed in the period between 1999 and 2003.
在HEVC之前的主要視頻編碼標準，是H.264/MPEG-4 AVC。AVC標準最早在1999到2003年發展起來。
H.264/MPEG-4 AVC has been an enabling technology for digital video in almost every area that was not previously covered by H.262/MPEG-2 Video and has substantially displaced the older standard within its existing application domains.
AVC是跨時代的。其應用在數字視頻中，涵蓋了幾乎所有H.262/MPEG-2 沒能覆蓋的領域，並且本質上在其覆蓋領域內代替了所有過去的標準。
AVC暴露的問題
However, an increasing diversity of services, the growing popularity of HD video, and the emergence of beyondHD formats (e.g., 4k×2k or 8k×4k resolution) are creating even stronger needs for coding efficiency superior to H.264/MPEG-4 AVC’s capabilities.
服務的日益多樣化、高清視頻的增多、超高清格式的出現，對編碼效率的要求越來越高，並且高於H.264/MPEG-4 AVC的性能。
當stereo 或 multiview capture and display出現時，這種需求愈發明顯。
並且，視頻通信對當今networks提出了挑戰。
HEVC的兩大著重點
HEVC不僅要能處理現存的AVC應用的所有設備，而且特別著重於兩大要點：
- increased video resolution
- increased use of parallel processing architectures
