Method for transmitting 360-degree video, method for receiving 360-degree video, apparatus for transmitting 360-degree video, and apparatus for receiving 360-degree video

A 360-degree video processing method performed by a 360-degree video reception apparatus, the method comprising:

• receiving a signal about 360-degree video, wherein the signal includes information on a 2D image and metadata;
• obtaining the information on the 2D image and the metadata from the signal;
• decoding the 2D image based on the information on the 2D image;
• and
• processing the decoded 2D image based on the metadata to render at least one part of the decoded 2D image on a 3D space,
• wherein the metadata includes mapping information for the decoded 2D image, and
• wherein the mapping information includes information on a yaw value and a pitch value for spherical coordinates of the 3D space to be rendered.

A 360-degree video reception apparatus comprising:

• a receiver configured to receive a signal about 360-degree video, wherein the signal includes information on a 2D image and metadata;
• a reception processor configured to obtain the information on the 2D image and the metadata from the signal;
• a data decoder configured to decode the 2D image based on the information on the 2D image;
• and
• a renderer configured to process the decoded 2D image based on the metadata to render at least one part of the decoded 2D image on a 3D space,
• wherein the metadata includes mapping information for the decoded 2D image, and
• wherein the mapping information includes information on a yaw value and a pitch value for spherical coordinates of the 3D space to be rendered.
