Video decoder for slices
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.
1. A method for decoding video comprising:
(a) decoding a frame of said video in a bitstream, said frame including both slices and tiles, each of said tiles defines a rectangular region of said frame and includes a plurality of macroblocks arranged in a raster scan order, said tiles are arranged in a raster scan order in said frame, said decoding of said frame including decoding each of said tiles in said raster scan order and decoding each of said plurality of macroblocks within each of said tiles in said raster scan order;
(b) receiving a flag in said bitstream to indicate at the end of one of said tiles when a location is the end of one of said tiles, wherein said bitstream includes zero-padding of bits at the end of the tile until byte alignment is reached.
2. The method of claim 1 wherein each of said tiles is decoded in a manner that is independent of one another.
3. The method of claim 1 wherein said zero-padding of bits is not entropy decoded.
4. The method of claim 1 wherein said location is provided in a header for said slice.
