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.
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]
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 ...
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.
