'''High Efficiency Video Coding tiers and levels''' are constraints that define a [[High Efficiency Video Coding]] (HEVC) bitstream in terms of maximum bit rate, maximum luma sample rate, maximum luma picture size, minimum compression ratio, maximum number of slices allowed, and maximum number of tiles allowed.<ref name=OverviewHEVCIEEE2012>{{cite news |title=Overview of the High Efficiency Video Coding (HEVC) Standard |author=G.J.
