51 LCU: Largest coding unit\
61 The largest coding block unit (LCU) applied in this codec is 128×128. In

83 For both intra and inter coded blocks, the coding block can be further
104 ranging from 4×4 to 64×64. If the coding block is smaller than or equal to
106 chroma blocks, the transform block size is identical to the coding block size.
107 Otherwise, if the coding block width or height is greater than 64, then both the
108 luma and chroma coding blocks will implicitly split into multiples of min(W,

483 quantization step size equal to 1, which is lossless coding mode.

491 **Coefficient coding**
493 For each transform unit, the coefficient coding starts with coding a skip sign,
495 end-of-block (EOB) position in case the transform coding is not skipped. After
725 ## Screen content coding
727 To improve the coding performance of screen content coding, the associated video
728 codec incorporates several coding tools，for example, intra block copy
735 Intra Block Copy (IntraBC) [2] is a coding tool similar to inter-picture
752 IntraBC is very effective for screen content coding, but it also brings a lot of
