1. A method of decoding with a processor a multiplexed image in a sequence of images, the method comprising: receiving a coded bitstream comprising a coded image in a multiplexed format, the coded image comprising samples of a first image and samples of a second image, wherein the multiplexed format is determined using SEI messaging in the coded bitstream; decoding with the processor the coded image to generate a decoded image; demultiplexing, based on the multiplexed format, with the processor the decoded image to generate decoded samples of the first image and decoded samples of the second image, wherein the decoded samples of the first image and the second image are arranged in accordance with the multiplexed format in alternating order within even lines of the decoded image and in the opposite order in odd lines of the decoded image, wherein the decoded samples of the first image represent samples of the first image in a first checkerboard pattern and the decoded samples of the second image represent samples of the second image in a second checkerboard pattern; upsampling with the processor the decoded samples of the first image to generate a first output image; and upsampling with the processor the decoded samples of the second image to generate a second output image.
