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 reference PSNR was based on the original 10-bit video sequences. In the performance comparison the Main 10 profile provided a 5% bit rate reduction for inter frame video coding compared to the Main profile. The performance comparison states that for the tested video sequences the Main 10 profile outperformed the Main profile. [166]
