Abstract

Official abstract text for this publication.

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.

First claim

Opening claim text (preview).

We claim: 1. A method for decoding video using a processor, the method comprising: (a) receiving a bit-stream of a frame of said video that includes at least one slice and at least one tile, where each of said at least one slice is decoded independently of another one of said at least one slice and includes said at least one tile, wherein said at least one tile is characterized that it is a rectangular region of said frame and includes coding units for said decoding arranged in a raster scan order; (b) receiving first information indicating whether location information of said at least one tile is transmitted within said at least one slice; (c) receiving second information suitable for decoding said at least one tile, said second information including a location of said at least one tile; (d) receiving a first flag at an end of said at least one tile; (e) ignoring bits in a bit-stream until reading from a pre-defined position when receiving said first flag, wherein the pre-defined position is a byte aligned position; (f) initializing a decoding process at a beginning of each of the at least one tile; and (g) providing a second flag that indicates if tiles are being used.
