Abstract: A method of processing an immersive video includes classifying view images into a basic image and an additional image, performing pruning with respect to view images by referring to a result of classification, generating atlases based on a result of pruning, generating a merged atlas by merging the atlases into one atlas, and generating configuration information of the merged atlas.

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, the metadata may include first threshold information that becomes a criterion for distinguishing between a valid pixel and an invalid pixel in the atlas video.

Abstract: Disclosed herein is an immersive video formatting method and apparatus for supporting motion parallax, The immersive video formatting method includes acquiring a basic video at a basic position, acquiring a multiple view video at at least one position different from the basic position, acquiring at least one residual video plus depth (RVD) video using the basic video and the multiple view video, and generating at least one of a packed video plus depth (PVD) video or predetermined metadata using the acquired basic video and the at least one RVD video.

Abstract: Disclosed is an apparatus and method of providing a high quality 360-degree VR image. A method of decoding a 360-degree VR image according to the present disclosure includes: receiving a bit stream including 360-degree VR image information; decoding information related to a 360-degree VR service from the bitstream; detecting a region of interest based on the information related to the 360-degree VR service; and providing to a user a 360-degree VR image for the region of interest.
