Abstract
A method for decoding video includes receiving a frame of the video that includes at least one slice and at least one tile. Each of the at least one slice and the at least one tile are not all aligned with one another. Each of the at least one slice is characterized that it is decoded independently of the other the at least one slice. Each of the at least one tile is characterized that it is a rectangular region of the frame and having coding units for the decoding arranged in a raster scan order. The at least one tile of the frame are collectively arranged in a raster scan order of the frame. At least one of (1) receiving entropy information suitable for decoding at least one of the tiles that is not aligned with any of the at least one slice, and (2) identifying at least one of the tiles that is not aligned with any of the at least one slice based upon signal within a bitstream of the frame without requiring entropy decoding to identify the signal.
