==Levels==

The HEVC standard defines thirteen levels.<ref name=OverviewHEVCIEEE2012/><ref name=HEVCITURecommendationH265/> A level is a set of constraints for a bitstream.<ref name=OverviewHEVCIEEE2012/><ref name=HEVCITURecommendationH265/> For levels below level 4 only the Main tier is allowed.<ref name=OverviewHEVCIEEE2012/><ref name=HEVCITURecommendationH265/> 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.<ref name=OverviewHEVCIEEE2012/><ref name=HEVCITURecommendationH265/>

<!-- Please don't change the default state of the table to collapsed using the mw-collapsed option since that causes problems with some web browsers such as making the customtoggle in the charttable not work when the page is refreshed or revisited. -->
