Abstract

Claims (31)

1 . An apparatus for decoding a picture from a bitstream, the apparatus comprising:

a memory; and

one or more processors coupled to the memory, the one or more processors configured to perform operations comprising:

deriving, from the bitstream, one or more tile rows and one or more tile columns to obtain a tile comprising a sequence of coding tree units (CTUs) that covers a rectangular region of the picture;

decoding or inferring, from the bitstream, a tile partitioning syntax element indicating a presence of tile partitioning information in the bitstream; and

deriving, from the tile partitioning information in the bitstream, a syntax element specifying heights of a plurality of rectangular regions within the tile, wherein the heights of the plurality of rectangular regions are specified as a number of CTU rows.

2 . The apparatus of claim 1 , wherein the tile partitioning information further comprises a second syntax element indicating a number of the plurality of rectangular regions within the tile.

3 . The apparatus of claim 1 , wherein the tile partitioning information is included in a picture parameter set.

4 . A method for decoding a picture from a bitstream, comprising:

deriving, from the bitstream, one or more tile rows and one or more tile columns to obtain a tile comprising a sequence of coding tree units (CTUs) that covers a rectangular region of the picture;

decoding or inferring, from the bitstream, a tile partitioning syntax element indicating a presence of tile partitioning information in the bitstream; and

deriving, from the tile partitioning information in the bitstream, a syntax element specifying heights of a plurality of rectangular regions within the tile, wherein the heights of the plurality of rectangular regions are specified as a number of CTU rows.

5 . The method of claim 4 , wherein the tile partitioning information further comprises a second syntax element indicating a number of the plurality of rectangular regions within the tile.

6 . The method of claim 4 , wherein the tile partitioning information is included in a picture parameter set.

7 . A non-transitory computer-readable medium including instructions which, when executed by one or more processors, cause the one or more processors to perform the method of claim 4 .

8 . A method for encoding a picture into a bitstream, comprising:

partitioning the picture with one or more tile rows and one or more tile columns to obtain a tile comprising a sequence of coding tree units (CTUs) that covers a rectangular region of the picture;

partitioning the tile with a plurality of horizontal boundaries to obtain a plurality of rectangular regions within the tile; and

encoding, into the bitstream, tile partitioning information comprising a syntax element specifying heights of the plurality of rectangular regions, wherein the heights of the plurality of rectangular regions are specified as a number of CTU rows.

9 . The method of claim 8 , wherein the tile partitioning information further comprises a second syntax element indicating a number of the plurality of rectangular regions within the tile.

10 . The method of claim 8 , wherein the tile partitioning information is included in a picture parameter set.

11 . The method of claim 8 , further comprising:

encoding, into the bitstream, a flag syntax element indicating a presence of the tile partitioning information.

12 . An apparatus for encoding a picture into a bitstream, the apparatus comprising:

a memory; and

one or more processors coupled to the memory, the one or more processors configured to perform the method of claim 8 .

13 . The apparatus of claim 12 , wherein the tile partitioning information further comprises a second syntax element indicating a number of the plurality of rectangular regions within the tile.

14 . The apparatus of claim 12 , wherein the tile partitioning information is included in a picture parameter set.

15 . The apparatus of claim 12 , the one or more processors configured further configured to perform operations comprising:

encoding, into the bitstream, a flag syntax element indicating a presence of the tile partitioning information.

16 . A non-transitory computer-readable medium including instructions which, when executed by one or more processors, cause the one or more processors to perform the method of claim 8 .
