METHOD AND APPARATUS FOR VIDEO ENCODING FOR EACH SPATIAL SUB-AREA, AND METHOD AND APPARATUS FOR VIDEO DECODING FOR EACH SPATIAL SUB-AREA

摘要

Provided are a video encoding method and a video decoding method according to spatial subdivisions based on splitting a picture into a first tile and a second tile, and splitting a current tile among the first tile and the second tile into at least one slice segment, encoding the first tile and the second tile, independently from each other, and encoding maximum coding units of a current slice segment among the at least one slice segment included in the current tile, with respect to the at least one slice segment included in the current tile.

1. An apparatus for decoding a video, the apparatus comprising :
a receiver configured to receive a bitstream; an extractor configured to obtain, from the bitstream, information about a location of a row boundary of a tile; and a decoder configured to determine tiles, including a current tile, based on the information about the location of the row boundary of the tile, and obtain, based on a split information of a coding unit, at least one coding unit from a maximum coding unit included in both the current tile and a current slice segment, wherein all maximum coding units in the current slice segment are included in the current tile, and when the split information indicate a split at a current depth, a coding unit of the current depth is split into coding units of a lower depth.
