Abstract
A method of decoding an image, includes obtaining at least one offset for a picture, deriving a variable for scaling for the picture based on the at least one offset, and performing inter prediction based on the variable for scaling for the picture. The at least one offset is defined with a direction of scaling.
Claims7
A method for decoding an image, the method comprising:
- receiving a bitstream including information on the image;
- acquiring partitioning information for a default coding unit included in the image from the bitstream;
- partitioning the default coding unit into a plurality of lower coding units based on the partitioning information for the default coding unit;
- and
- decoding each of the lower coding units to reconstruct the image,
- wherein the reconstructing the image comprises generating a prediction block for a block included in the image,
- wherein the lower coding unit is partitioned into a plurality of prediction units based on a size or a shape of the lower coding unit, and
- wherein the bitstream comprises information on rotation of the image.

A method for encoding an image, the method comprising:
- obtaining a default coding unit included in the image;
- partitioning the default coding unit into a plurality of lower coding units;
- determining partitioning information for the default coding unit;
- and
- encoding the partitioning information and each of the lower coding units to encode the image into a bitstream,
- wherein the encoding the image comprises generating a prediction block for a block included in the image,
- wherein the lower coding unit is partitioned into a plurality of prediction units based on a size or a shape of the lower coding unit, and
- wherein the bitstream comprises information on rotation of the image.

A method for transmitting a bitstream, the method comprising:
- obtaining a default coding unit included in the image;
- partitioning the default coding unit into a plurality of lower coding units;
- determining partitioning information for the default coding unit;
- encoding the partitioning information and each of the lower coding units to encode the image into a bitstream;
- and
- transmitting the bitstream,
- wherein the encoding comprises generating a prediction block for a block included in the image,
- wherein the lower coding unit is partitioned into a plurality of prediction units based on a size or a shape of the lower coding unit, and
- wherein the bitstream comprises information on rotation of the image.
