Abstract

Decoding coded pictures of a video includes receiving, by a decoder apparatus, a bitstream comprising an encoded representation of first pictures of a first resolution version of the video and decoding the coded first pictures into first pictures, the first pictures being associated with corresponding second pictures of a second resolution version of the video, the first pictures being formed by sampling the corresponding second pictures using a sampling lattice. Signalling information received in the bitstream informs the decoder apparatus about a resolution change. The method includes identifying at least one of the first pictures as a first base picture and identifying one or more auxiliary pictures, the first base picture being associated with a corresponding second picture, and, each of the one or more auxiliary pictures being formed based on sampling the second picture using a different sampling lattice of the plurality of sampling lattices. The method further includes receiving an encoded representation of the one or more auxiliary pictures in the bitstream, decoding the encoded representation of the one or more auxiliary pictures into one or more auxiliary pictures and constructing a reference picture of the second resolution based on the first base picture and the one or more auxiliary pictures. The method further includes receiving an encoded representation of second pictures in the bitstream and decoding at least part of the encoded representation of the second pictures into one or more second pictures using the constructed reference picture.
