Method of processing immersive video and method of producing immersive video

Disclosed herein are a video encoding/decoding method and apparatus. The video decoding method according to the present disclosure includes: when a current picture is composed of a plurality of tiles and a current tile among the plurality of tiles is partitioned into a plurality of slices, decoding information on the number of slices in tile that indicates the number of the plurality of slices comprised in the current tile; decoding information on a slice height in tile that indicates a height of the plurality of slices comprised in the current tile; and determining the number of the plurality of slices comprised in the current tile and a height of the plurality of slices comprised in the current tile.

Image encoding/decoding method and device

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.

Method for processing immersive video and method for producing immersive video

Disclosed herein is an immersive video processing method. The immersive video processing method includes: determining a priority order of pruning for input videos; extracting patches from the input 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 information on a priority order of pruning among input videos.

A video encoding method of encoding a multi-view image including one or more basic view images and a plurality of reference view images includes determining a pruning order of the plurality of reference view images, acquiring a plurality of residual reference view images, by pruning the plurality of reference view images based on the one or more basic view images according to the pruning order, encoding the one or more basic view images and the plurality of residual reference view images, and outputting a bitstream including encoding information of the one or more basic view images and the plurality of residual reference view images.

Video encoding method and video decoding method

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.

An MPEG media transport (MMT) apparatus and method for processing stereoscopic video data are provided. The MMT apparatus includes an asset file generator configured to generate a single asset file that contains an entire or part of the stereoscopic video data; and a signaling message generator configured to generate a signaling message for delivery or consumption of the stereoscopic video data. At least one of the generated single asset file and the generated signaling message contains stereoscopic video information related to the stereoscopic video data.

MMT apparatus and MMT method for processing stereoscopic video data

Disclosed herein is an immersive video processing method. The immersive video processing method may include classifying a multiplicity of view videos into a base view and an additional view, generating a residual video for the additional view video classified as an additional view, packing a patch, which is generated based on the residual video, into an atlas video, and generating metadata for the patch.

Provided is a method of processing MPEG data, the method including: obtaining at least one access unit including media data coded through processing including an encapsulation and a packetization; generating at least one media processing unit (MPU) by grouping at least one access unit; determining a duration flag indicating whether duration information of the at least one access unit is valid, in a corresponding MPU; and inserting the duration flag into a header of the corresponding MPU.
