    Technical Features
High-level Structure
- High-level support for frame rate temporal nesting and random access
- Rectangular tile-structured scanning
- Wavefront-structured processing dependencies for parallelism
- Slices with spatial granularity possibly smaller than largest coding unit: 16x16 or larger


Coding units, Prediction units, and Transform units
- Coding unit quadtree structure (square coding unit block sizes 2Nx2N, for N=4, 8, 16, 32; i.e., up to 64x64 luma samples in size)
- Prediction units (for coding unit size 2Nx2N: for Inter, 2Nx2N, 2NxN, Nx2N, and, for N>4, also 2Nx(N/2+3N/2) & (N/2+3N/2)x2N;
for Intra, only 2Nx2N and, for N=4, also NxN
- Transform unit tree structure within coding unit (maximum of 3 levels)
- Transform block size of 4x4 to 32x32 samples (always square for Intra; also non-square 4x16, 16x4, 8x32, 32x8 for Inter)


Spatial Signal Transformation and PCM Representation
- DCT-like integer block transform; for Intra also a DST-based integer block transform (selected based on the intra prediction
mode)
- Transforms can cross prediction unit boundaries for Inter; not for Intra
- PCM coding with worst-case bit usage limit


In-Loop Filtering
- Deblocking filter
- Sample-adaptive offset filter
- Adaptive loop filter
