Coding and decoding of interleaved image data

A method to decode an encoded video signal with a processor, the method comprising:

• decoding the encoded video signal comprising more than one image per frame in the video signal;
• de-interleaving 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 image and one or more groups of video data from a second image, 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 sub-images obtained through separating sampled image data generated through sub-sampling images are tiled together, and wherein the arrangement indicates that the one or more groups of video data from the first image are tiled into a first rectangular block of a image frame of a video stream, and the one or more groups of video data from the second image 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 image frame;
• and
• up-converting the one or more groups of video data from the first image and the one or more groups of video data from the second image into the first image and the second image respectively according to horizontal sampling.
