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
