Decoding device, decoding method, and program

摘要

The present technique relates to a decoding device, a decoding method, and a program which can decode an image in parallel for each of tiles of the image. A parallel decoding unit decodes the image encoded by for example an encoding method called high efficiency video coding (HEVC) in parallel for each tile used for example the encoding method called HEVC. The present technique can be applied to a decoding device for receiving and decoding an encoded stream encoded by for example the encoding method called HEVC, and generates an image.

主权项

1. A decoding device comprising a parallel decoding unit configured to
determine whether a smallest unit for independent decoding of an image is a slice or a tile, based on at least one of slice address information and tile address information representing an address of a largest coding unit (LCU) at the head of the image, and decode the image in parallel for each slice or for each tile of the image, wherein, when it is determined that the smallest unit for independent decoding of the image is the slice, the parallel decoding unit decodes the image in parallel for each slice based on the slice address information, wherein, when it is determined that the smallest unit for independent decoding of the image is the tile, the parallel decoding unit decodes the image in parallel for each tile based on the tile address information, and wherein the parallel decoding unit is implemented via at least one processor.
