https://en.wikipedia.org/wiki/High_Efficiency_Video_Coding_tiers_and_levelsHigh 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. Lower tiers are more constrained than higher tiers and lower levels are more constrained than higher levels.

High Efficiency Video Coding – Wikipedia
https://de.wikipedia.org/wiki/High_Efficiency_Video_Coding- Ab 2004 untersuchte die ITU-T Video Coding Experts Group (VCEG) Möglichkeiten, um die Komprimierung von Videos im Vergleich zu H.264/MPEG-4 AVC zu verbessern. Im Januar 2005 definierte die VCEG Schlüsselgebiete (KTA, Key Technical Areas) für weitere Untersuchungen. Die VCEG entwickelte eine Referenzsoftware, um Verbesserungen in diesen Schlüsselgebieten zu er…

High Efficiency Video Coding - VideoLAN Wiki
https://wiki.videolan.org/High_Efficiency_Video_CodingHigh Efficiency Video Coding or HEVC is the upcoming successor to H.264. It is sometimes (unofficially) called H.265 or H.265/HEVC to lend an idea that it builds upon H.264/MPEG-4 AVC . It claims a greater compression ratio through lossy means at no cost to apparent fidelity.
