US Patent 9247258 Unified design for picture partitioning schemes

A video coder can control in-picture prediction across slice boundaries within a picture. In one example, a first syntax element can control if in-picture prediction across slice boundaries for slices of a picture. If in-picture prediction across slice boundaries is enabled for the picture, then a second syntax element can control, for an individual slices, if in-picture prediction across slice boundaries is enabled for the slice.
