Abstract
An image decoding method according to the present disclosure comprises the steps of: when a random access: is performed, sequentially decoding pictures belonging to a random access group; and outputting, as a reconstructed picture, a last picture from among the pictures belonging to the random access group.
Claims14
A method of decoding a video, the method comprising:
- decoding a plurality of pictures included in a random access group,
- wherein a size of a completely reconstructed region is gradually increased over the plurality of pictures in the random access group,
- wherein a completely reconstructed region of a first picture in the random access group consists only of intra-coded regions,
- wherein a last picture of the random access group is entirely composed of a completely reconstructed region,
- wherein in response to a current picture being one of the plurality of pictures except for the first picture and the last picture, the current picture consists of a completely reconstructed region and an incompletely coded region,
- wherein the completely reconstructed region of the current picture consists of an intra coded region and a completely coded region,
- wherein a size and a position of the completely coded region of the current picture correspond to a completely reconstructed region of a previous coded picture, and
- wherein information in the incompletely coded region of the current picture is not referred to for decoding the completely reconstructed region of the current picture.

A method of encoding a video, the method comprising:
- encoding a plurality of pictures included in a random access group,
- wherein a size of a completely reconstructed region is gradually increased over the plurality of pictures in the random access group,
- wherein a completely reconstructed region of a first picture in the random access group consists only of intra-coded regions,
- wherein a last picture of the random access group is entirely composed of a completely reconstructed region,
- wherein in response to a current picture being one of the plurality of pictures except for the first picture and the last picture, the current picture consists of a completely reconstructed region and an incompletely coded region,
- wherein the completely reconstructed region of the current picture consists of an intra coded region and a completely coded region,
- wherein a size and a position of the completely reconstructed region of the current picture correspond to a completely reconstructed region of a previous coded picture, and
- wherein information in the incompletely coded region of the current picture is not referred to for encoding the completely reconstructed region of the current picture.

- encoding a plurality of pictures in a random access group;
- and
- a transmitter configured to transmit the compressed video data,
- wherein a size of a completely reconstructed region is gradually increased over the plurality of pictures in the random access group,
- wherein a completely reconstructed region of a first picture in the random access group consists only of intra-coded regions,
- wherein a last picture of the random access group is entirely composed of a completely reconstructed region,
- wherein in response to a current picture being one of the plurality of pictures except for the first picture and the last picture, the current picture consists of a completely reconstructed region and an incompletely coded region,
- wherein the completely reconstructed region of the current picture consists of an intra coded region and a completely coded region,
- wherein a size and a position of the completely coded region of the current picture correspond to a completely reconstructed region of a previous coded picture, and
- wherein information in the incompletely coded region of the current picture is not referred to for encoding the completely reconstructed region of the current picture.
