Coding and decoding of interleaved image data

A non-transitory computer-readable storage medium having stored thereon computer-executable instructions which when executed by a computing device cause the computing device to:

• decode an encoded video signal comprising more than one picture per frame in the video signal;
• de-interleave groups of video data interleaved in a frame format in the decoded video signal, wherein the groups of video data comprise one or more groups of video data from a first picture and one or more groups of video data from a second picture, wherein de-interleaving the groups of video data comprises de-interleaving the groups of video data from multiple interleaving formats according to an identifier of an arrangement indicating how the groups of video data are tiled together, and wherein the arrangement indicates that the one or more groups of video data from the first picture are tiled into a first rectangular block of an picture frame, and the one or more groups of video data from the second picture are tiled into a second rectangular block of the frame, and wherein the first rectangular block is positioned in side-by-side relation with the second rectangular block in the picture frame;
• and
• up-convert the one or more groups of video data from the first picture and the one or more groups of video data from the second picture into the first picture and the second picture respectively according to horizontal sampling.
