Abstract
A mechanism is provided that implements video coding and decoding such that only a specific partial image region on a screen can be independently decoded. A video decoding apparatus (31) according to an aspect of the present invention configures, in intra prediction, inter prediction, loop filter processing, or the like, a partial image region in a picture, handles a region outside the partial image region in a similar manner to a region outside the picture, and does not apply such restriction to a non-partial image region other than the partial image region in the picture.
Claims13
A method of signaling gradual refresh for decoding a set of pictures, the method including:
- identifying a first picture in a set of pictures as being associated with a gradual refreshed picture;
- storing a network abstraction layer (NAL) unit type in a coded stream associated with the first picture, the NAL unit type identifying presence of the gradual refreshed picture;
- and
- storing, in the coded stream, an enable flag to identify use of gradual refresh for decoding at least a subset of the pictures in the set of pictures.
