Abstract
According to one aspect of the present disclosure, a decoder includes memory and a processor coupled to the memory. The processor is configured to split a current picture into tiles, generate a slice having a rectangular shape and located at a lower-right corner of the current picture, the slice including at least a part of a tile among the tiles, generate first information on a region of the slice with header information, the header information not including information identical to the first information, and decode the slice with the first information.
Claims13
A decoder that decodes an image, the decoder comprising:
- circuitry;
- and
- memory coupled to the circuitry, wherein
- in operation, the circuitry:
- splits a current picture to be decoded into two or more tiles;
- and
- decodes the current picture by performing the decoding on a slice, the slice being rectangular-shaped, the slice being made up of one or more tiles or a part of a tile obtained by the splitting,
- in the decoding of the current picture, the circuitry sets first information on a region in a predetermined manner without retrieving the first information from header information, the region being occupied by a slice located at a lower-right corner of the current picture, and
- the first information is not included in the header information.
A decoding method of decoding an image, the decoding method comprising:
- splitting a current picture to be decoded into two or more tiles;
- and
- decoding the current picture by performing the decoding on a slice, the slice being rectangular-shaped, the slice being made up of one or more tiles or a part of a tile obtained by the splitting, wherein
- the decoding of the current picture includes setting first information on a region in a predetermined manner without retrieving the first information from header information, the region being occupied by a slice located at a lower-right corner of the current picture, and
- the first information is not included in the header information.
A decoder comprising:
- memory;
- and
- a processor coupled to the memory and configured to:
- split a current picture into tiles;
- generate a slice having a rectangular shape and located at a lower-right corner of the current picture, the slice including at least a part of a tile among the tiles;
- generate first information on a region of the slice with header information, the header information not including information identical to the first information;
- and
- decode the slice with the first information.
