  2. High Efficiency Video Coding tiers and levels - Wikipedia

    en.wikipedia.org/wiki/High_Efficiency_Video...

    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.

    In addition, some DVDs have DTS tracks, with most being 5.1 channel mixes (a few releases, however, have 6.1 "matrixed" or even discrete 6.1 tracks). Blu-ray and digital cinema both have eight-channel capability which can be used to provide either 5.1 or 7.1 surround sound . 7.1 is an extension of 5.1 that uses four surround zones: two at the ...

    In the comparison, the HM-15.0 HEVC encoder had the highest coding efficiency and, on average, for the same subjective quality the bit rate could be reduced by 49.4% compared with the VP9 1.2.0–5183 encoder, and it could be reduced by 52.6% compared with the JM-18.8 H.264/MPEG-4 AVC encoder.

    The DD+ extension bitstream is used on players that support it by replacing the rear channels in the 5.1 setup with higher fidelity versions, along with providing a possible channel extension to 6.1 or 7.1. The complete audio track is allowed a combined bitrate of 1.7 Mbit/s: 640 kbit/s for the AC-3 5.1 core, and 1 Mbit/s for the DD+ extension.

  7. Standard RAID levels - Wikipedia

    en.wikipedia.org/wiki/Standard_RAID_levels

    The most common types are RAID 0 (striping), RAID 1 (mirroring) and its variants, RAID 5 (distributed parity), and RAID 6 (dual parity). Multiple RAID levels can also be combined or nested, for instance RAID 10 (striping of mirrors) or RAID 01 (mirroring stripe sets).

    the "Vega" 7nm instruction set architecture (also referred to as Graphics Core Next 5.1). An LLVM compiler back end is available for the GCN instruction set. [5] It is used by Mesa 3D. GNU Compiler Collection 9 supports GCN 3 and GCN 5 since 2019 [6] for single-threaded, stand-alone programs, with GCC 10 also offloading via OpenMP and OpenACC. [7]

  9. DECT - Wikipedia

    en.wikipedia.org/wiki/DECT

    DECT 6.0 is a North American marketing term for DECT devices manufactured for the United States and Canada operating at 1.9 GHz. The "6.0" does not equate to a spectrum band; it was decided the term DECT 1.9 might have confused customers who equate larger numbers (such as the 2.4 and 5.8 in existing 2.4 GHz and 5.8 GHz cordless telephones) with ...
