Abstract
The present disclosure relates to a method for transmitting metadata of an omnidirectional image by a transmission apparatus, the method comprising the steps of: projecting an omnidirectional image into a planar image based on a 3-dimensional (3D) geometry corresponding to the omnidirectional image; and transmitting metadata including type information of the 3D geometry, information for a region on the projected planar image, and information for an area on the omnidirectional image which is mapped to the region.

A method for transmitting, by a transmission apparatus, metadata of an omnidirectional video, the method comprising:
- projecting an omnidirectional video onto a planar video based on a three-dimensional (3D) geometry corresponding to the omnidirectional video;
- and
- transmitting metadata comprising type information of the 3D geometry, information for a region on the projected planar video, and information for an area on the omnidirectional video which is mapped to the region.
A method for receiving, by a reception apparatus, metadata of an omnidirectional video, the method comprising:
- receiving metadata comprising type information of a three-dimensional (3D) geometry corresponding to an omnidirectional video, information for a region on a planar video, and information for an area on the omnidirectional video which is mapped to the region;
- and
- projecting the planar video onto the 3D geometry corresponding to the omnidirectional video.
A transmission apparatus for transmitting metadata of an omnidirectional video, the apparatus comprising:
- a controller configured to project an omnidirectional video onto a planar video using a three-dimensional (3D) geometry corresponding to the omnidirectional video;
- and
- a transceiver configured to transmit metadata comprising type information of the 3D geometry, information for a region on the projected planar video, and information for an area on the omnidirectional video which is mapped to the region.
A reception apparatus for receiving metadata of an omnidirectional video, the apparatus comprising:
- a transceiver configured to receive metadata comprising type information of a three-dimensional (3D) geometry corresponding to an omnidirectional video, information for a region on a planar video, and information for an area on the omnidirectional video which is mapped to the region;
- and
- a controller configured to project the planar video onto the omnidirectional video using the 3D geometry corresponding to the omnidirectional video.
