Abstract: A method and apparatus are provided for processing information about an omni-directional image. The method includes generating a first two-dimensional (2D) image projected from a first omni-directional image, by setting points on the first omni-directional image, which intersect a straight line passing through a first position that is a center of the first omni-directional image and a second position that is a center of a second omni-directional image, to a first pole and a second pole, generating a second 2D image projected from the second omni-directional image, by setting points on the second omni-directional image, which intersect the straight line passing through the first position and the second position, to a third pole and a fourth pole, and generating a third 2D image corresponding to a 2D image projected from a third omni-directional image centered in a third position between the first position and the second position, based on the first 2D image and the second 2D image.

Abstract: Methods and apparatuses are provided for transmitting information about an omni-directional image based on user motion information by a server. Motion parameters are received from an apparatus worn by a user for displaying an omni-directional image. User motion information is generated based on the received motion parameters. First packing information corresponding to a user position is generated based on the user motion information. Second packing information corresponding to a position in close proximity to the user position is generated based on the user motion information. Third packing information is generated based on the first packing information and the second packing information At least one of the first packing information, the second packing information, and the third packing information is transmitted to the apparatus.
