A particular method includes accessing a video picture that includes multiple pictures combined into a single picture (826), accessing information indicating how the multiple pictures in the accessed video picture are combined (806, 808, 822), decoding the video picture to provide a decoded representation of at least one of the multiple pictures (824, 826), and providing the accessed information and the decoded video picture as output (824, 826). Some other implementations format or process the information that indicates how multiple pictures included in a single video picture are combined into the single video picture, and format or process an encoded representation of the combined multiple pictures. ## Claims ### Claim 1 A method for decoding coded video pictures, the method comprising: receiving in a processor a coded video bitstream comprising coded video pictures; determining from the coded video bitstream a single picture in a rectangular frame, wherein the single picture includes a first picture and a second picture tiled together; accessing information to determine how the first picture and the second picture are tiled together using two or more tiles, wherein the accessed information indicates that the second picture is split into two or more parts so that it can be arranged in the rectangular frame together with the first picture; and decoding the single picture into the first picture and the second picture. ### Claim 2 (depends on 1) The method of claim 1 wherein at least one of the first picture or a part of the second picture is individually flipped in the horizontal or the vertical direction. ### Claim 3 (depends on 1) The method of claim 1, wherein the single picture further comprises a depth image added as a tile, wherein the depth image is associated with the first picture or the second picture. ### Claim 4 (depends on 1) The method of claim 1, wherein the first picture and the second picture correspond to a left view and a right view of a stereoscopic image. ### Claim 5 (depends on 1) The method of claim 1, further comprising: accessing upscaling information related to the first picture or the second picture. ### Claim 6 (depends on 1) The method of claim 1, further comprising: accessing offset information of the position of the tiles in the single picture with respect to its origin. ### Claim 7 (depends on 6) The method of claim 6, wherein the offset information comprises one or more of a left offset, a right offset, a top offset, or a bottom offset. ### Claim 8 A method for encoding video pictures into a coded bitstream, the method comprising: receiving video pictures; tiling together multiple pictures into a single video picture in a rectangular frame, the multiple pictures including a first picture and a second picture; generating information in a signaling section indicating how the multiple pictures are combined into tiles, wherein the generated information indicates that the second picture is split into two or more parts so that it can be arranged in the rectangular frame together with the first picture; encoding the single video picture to provide a coded picture; and combining the signaling section and the coded picture as output. ### Claim 9 (depends on 8) The method of claim 8, wherein the information in the signaling section indicates that at least one of the first picture or a part of the second picture is individually flipped in the horizontal or the vertical direction. ### Claim 10 (depends on 8) The method of claim 8, wherein the single video picture further comprises a depth image added as a tile, wherein the depth image is associated with the first picture or the second picture.
