The HEVC standard defines two tiers: Main and High. [1] [2] The Main tier is a lower tier than the High tier. [1] [2] The tiers were made to deal with applications that differ in terms of their maximum bit rate. [1] The Main tier was designed for most applications while the High tier was designed for very demanding applications. [1]
In a subjective video performance comparison released in May 2014, the JCT-VC compared the HEVC Main profile to the H.264/MPEG-4 AVC High profile. The comparison used mean opinion score values and was conducted by the BBC and the University of the West of Scotland. The video sequences were encoded using the HM-12.1 HEVC encoder and the JM-18.5 ...
On March 9, 2015, Nvidia released VDPAU version 1.0 which supports HEVC decoding for the Main, Main 4:4:4, Main Still Picture, Main 10, and Main 12 profiles. [ 110 ] On March 31, 2015, VITEC announced the MGW Ace which was the first 100% hardware-based portable HEVC encoder that provides mobile HEVC encoding.
The tests also showed that it took 60% longer to decode HEVC video encoded at 16×16 CTU size than at 64×64 CTU size. [2] The tests showed that large CTU sizes increase coding efficiency while also reducing decoding time. [2] The tests were conducted with the Main profile of HEVC based on equal PSNR. [2]
x265 is an encoder for creating digital video streams in the High Efficiency Video Coding (HEVC/H.265) video compression format developed by the Joint Collaborative Team on Video Coding (JCT-VC). [ 4 ] [ 5 ] [ 6 ] It is available as a command-line app or a software library , under the terms of GNU General Public License (GPL) version 2 or later ...
An acrostic puzzle published in State Magazine in 1986. An acrostic is a type of word puzzle, related somewhat to crossword puzzles, that uses an acrostic form. It typically consists of two parts. The first part is a set of lettered clues, each of which has numbered blanks representing the letters of the answer.
Taking this one stage further, the clue word can hint at the word or words to be abbreviated rather than giving the word itself. For example: "About" for C or CA (for "circa"), or RE. "Say" for EG, used to mean "for example". More obscure clue words of this variety include: "Model" for T, referring to the Model T.
The solver is given a grid and a list of words. To solve the puzzle correctly, the solver must find a solution that fits all of the available words into the grid. [1] [2] [8] [9] Generally, these words are listed by number of letters, and further alphabetically. [2] [8] Many times, one word is filled in for the solver to help them begin the ...
