The HEVC standard defines thirteen levels. [1] [2] A level is a set of constraints for a bitstream.[1] [2] For levels below level 4 only the Main tier is allowed.[1] [2] A decoder that conforms to a given tier/level is required to be capable of decoding all bitstreams that are encoded for that tier/level and for all lower tiers/levels.
The Screen-Extended High Throughput 4:4:4 10 profile has an HbrFactor 6 times higher than most inter frame HEVC profiles allowing it to have a maximum bit rate 6 times higher than the Main 4:4:4 10 profile. HEVC decoders that conform to the Screen-Extended High Throughput 4:4:4 10 profile must be capable of decoding bitstreams made with the ...
On June 10, 2013, Vanguard Video announced that support for the Main 10 profile was added to their V.265 professional HEVC encoder. [51] V.265 is the first real time HEVC software encoder to support the Main 10 profile. [51] On June 20, 2013, Imagination Technologies announced their PowerVR Series5 HEVC decoder. [52]

x265 source code is written in C++ and x86 assembly. [3]x265 supports the Main, Main 10, Main 12 and Main Still Picture profiles [11] of HEVC (including intra-only profiles), utilizing a bit depth of either 8 bits or 10 bits per sample YCbCr with 4:2:0, 4:2:2 or 4:4:4 chroma subsampling.
UHD Phase A consumer devices should be able to decode the High Efficiency Video Coding (HEVC) Main 10 profile Level 5.1 and process Hybrid log–gamma (HLG10) or Perceptual quantizer /HDR10 content using Rec. 2020 color primaries.
The tests also showed that it took 60% longer to decode HEVC video encoded at 16×16 CTU size than at 64×64 CTU size. [2] The tests showed that large CTU sizes increase coding efficiency while also reducing decoding time. [2] The tests were conducted with the Main profile of HEVC based on equal PSNR. [2]
The city’s hated new congestion toll could dangerously delay FDNY response times — meaning the “difference between life and death,” unions repping thousands of Bravest warned Sunday. The ...
