| dbo:abstract |
Coding tree unit (CTU) is the basic processing unit of the High Efficiency Video Coding (HEVC) video standard and conceptually corresponds in structure to macroblock units that were used in several previous video standards. CTU is also referred to as largest coding unit (LCU). A CTU can be between 16×16 pixels and 64×64 pixels in size with a larger size usually increasing coding efficiency. The first video standard that uses CTUs is HEVC/H.265 which became an ITU-T standard on April 13, 2013. (en) 編碼樹單元（英語：Coding Tree Unit，縮寫：CTU）是H.265/高效率視訊編碼（High Efficiency Video Coding, HEVC）的處理單元。此處理單元類似H.264/高階視訊編碼（Advanced Video Coding, AVC）中的宏區塊（Macroblock）。編碼樹單元的大小可以從16x16到64x64，使用比H.264更大的處理單元得到更好的壓縮效果。 (zh) |
