Abstract: A video decoding method comprises receiving a plurality of atlases and metadata, unpacking patches included in the plurality of atlases based on the plurality of atlases and the metadata, reconstructing view images including an image of a basic view and images of a plurality of additional views, by unpruning the patches based on the metadata, and synthesizing an image of a target playback view based on the view images. The metadata is data related to priorities of the view images.

Abstract: A method of producing an immersive video comprises decoding an atlas, parsing a flag for the atlas, and producing a viewport image using the atlas. The flag may indicate whether the viewport image is capable of being completely produced through the atlas, and, according to a value of the flag, when the viewport image is produced, it may be determined whether an additional atlas is used in addition to the atlas.

Abstract: A method and device for increasing a resolution for each viewpoint in a glassless three-dimensional (3D) display. A method of controlling a three-dimensional (3D) display device including a display panel and a lens includes performing time-division on a plurality of viewpoint images such that each of the viewpoint images is divided into n division images, transferring the division images to the display panel by increasing n times a frame rate of the division images, and controlling the lens such that the division images transferred to the display panel pass through a lens cell.

Abstract: Disclosed herein is an immersive video processing method. The immersive video processing method includes: determining a priority order of pruning for source videos; extracting patches from the source videos based on the priority order of pruning; generating at least one atlas based on the extracted patches; and encoding metadata. Herein, a first flag indicating whether or not an atlas includes a patch including information on an entire region of a first source video may be encoded into the metadata.

Abstract: A method and apparatus for generating frames to apply error correction to data including a plurality of consecutive data groups are provided. Upon receiving input of an n-th data group consisting of a plurality of priority groups with different priority levels, the number of first code rate frames, which is the number of frames in the n-th data group for which a first code rate is used, is calculated based on the number of first code rate bits calculated based on the ratio of the length of data in an (n−1)-th data group for which the first code rate is used. The number of second code rate frames, which is the number of frames in the n-th data group for which the second code rate is used, is calculated based on the number of second code rate bits calculated based on the number of first code rate bits. Frames for error correction are generated based on the number of first code rate frames and the number of second code rate frames.
