The HEVC standard defines two tiers: Main and High. [1] [2] The Main tier is a lower tier than the High tier. [1] [2] The tiers were made to deal with applications that differ in terms of their maximum bit rate. [1] The Main tier was designed for most applications while the High tier was designed for very demanding applications. [1]
In a subjective video performance comparison released in May 2014, the JCT-VC compared the HEVC Main profile to the H.264/MPEG-4 AVC High profile. The comparison used mean opinion score values and was conducted by the BBC and the University of the West of Scotland. The video sequences were encoded using the HM-12.1 HEVC encoder and the JM-18.5 ...
High 4:4:4 Predictive Profile (Hi444PP): This profile builds on top of the High 4:2:2 Profile, supporting up to 4:4:4 chroma sampling, up to 14 bits per sample, and additionally supporting efficient lossless region coding and the coding of each picture as three separate color planes.
On January 15, 2014, oViCs announced the ViC-1 HEVC decoder which supports the Main 10 profile at up to 4K at 120 fps. [90]On February 13, 2014, PathPartner Technology Pvt.Ltd announced HEVC Decoder on ARM Cortex-A Family Processors which takes advantage of the full capabilities of mobile SoCs built on latest ARM processors.

High Efficiency Video Coding (HEVC, ITU-T H.265) [14] is an encoding format for graphic data, first standardized in 2013. It is the primarily used and implied default codec for HEIF as specified in the normative Annex B to ISO/IEC 23008-12 HEVC Image File Format .
x265 is an encoder for creating digital video streams in the High Efficiency Video Coding (HEVC/H.265) video compression format developed by the Joint Collaborative Team on Video Coding (JCT-VC). [ 4 ] [ 5 ] [ 6 ] It is available as a command-line app or a software library , under the terms of GNU General Public License (GPL) version 2 or later ...
Coding tree unit (CTU) is the basic processing unit of the High Efficiency Video Coding (HEVC) video standard and conceptually corresponds in structure to macroblock units that were used in several previous video standards.
