Abstract: 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.

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 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.
