A method of decoding a video, the method comprising:
- determining a random access group including a plurality of pictures;
- and
- decoding the plurality of pictures in the 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, and
- wherein a last picture of the random access group is entirely composed of a completely reconstructed region.
