Abstract: A method of switching an atlas according to a watching position according to the present disclosure includes acquiring information on a view image required to reproduce a viewport image; acquiring information of a first atlas mapped to the view image; and receiving a bitstream of the first atlas and a bitstream of a second atlas different from the first atlas. In this case, when it is determined that atlas switching is necessary, reception of any one of a bitstream of the first atlas and a bitstream of the second atlas may be stopped and a bitstream of a third atlas may be newly received.

Abstract: A method of processing an immersive video includes classifying each of a plurality of objects included in a view image as one of a first object group and a second object group, acquiring a patch for each of the plurality of objects, and packing patches to generate at least one atlas. In this instance, patches derived from objects belonging to the first object group may be packed in a different region or a different atlas from a region or an atlas of patches derived from objects belonging to the second object group.

Abstract: A video encoding/decoding method and apparatus is provided. The image decoding method includes acquiring image data of images of a plurality of views, determining a basic view and a plurality of reference views among the plurality of views, determining a pruning order of the plurality of reference views, and parsing the image data based on the pruning order and decoding an image of the basic view and images of the plurality of reference views.

Abstract: An image encoding method according to the present disclosure may include classifying viewpoint images into a basic image and an additional image; performing pruning on an additional image based on the classification result, generating an atlas by packing patches obtained as a result of performing the pruning; and encoding the atlas and metadata for the atlas. In this case, a margin may be set for a patch within the atlas.

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

Abstract: Provided are a method of buffering a media transport stream in a heterogeneous network environment and an image receiving apparatus using the same. A first transport stream corresponding to a first image through a first network is received and a second transport stream corresponding to a second image through a second network is received. The first image corresponding to the first transport stream is buffered based on a preset minimum transmission delay difference, and then the buffered first image and the second image corresponding to the second transport stream are processed.

Abstract: A method for decoding a video including a plurality of views, according to one embodiment of the present invention, comprises the steps of: configuring a base merge motion candidate list by using motion information of neighboring blocks and a time correspondence block of a current block; configuring an extended merge motion information list by using motion information of a depth information map and a video view different from the current block; and determining whether neighboring block motion information contained in the base merge motion candidate list is derived through view synthesis prediction.
Abstract translation: 根据本发明的一个实施例的用于解码包括多个视图的视频的方法包括以下步骤：通过使用相邻块的运动信息和当前块的时间对应块来配置基本合并运动候选列表; 通过使用与当前块不同的深度信息映射和视频视图的运动信息来配置扩展合并运动信息列表; 并且通过视图合成预测来确定包含在基本合并运动候选列表中的相邻块运动信息。
