APPARATUS FOR ENTROPY-DECODING SLICE SEGMENT

摘要

Provided a video decoding apparatus comprising an obtaining unit configured for obtaining, from a bitstream, information about a maximum size of a coding unit and first information indicating whether a dependent slice segment is permitted to be included in a picture, and a decoder configured for determining at least one maximum coding unit included in a first slice segment, based on a maximum coding unit size which is determined by using the information about the maximum size. The obtaining unit is further configured for obtaining, from the bitstream, second information indicating whether a current maximum coding unit is at an end of the first slice segment or not. The decoder is further configured for storing a context variable of the first slice segment if the first information indicates that a dependent slice segment is permitted to be included in the picture and the second information indicates that a current maximum coding unit is at an end of the first slice segment. The decoder further configured for decoding a dependent slice segment which is located next to the first slice segment in the picture by using the stored context variable
