METHOD AND DEVICE FOR TRANSMITTING AND RECEIVING METADATA ON COORDINATE SYSTEM OF DYNAMIC VIEWPOINT

摘要

In a 360-degree video data processing method performed by a 360-degree video receiving device according to one embodiment of the present invention, the method comprises the steps of: receiving information on 360-degree video data; obtaining information and metadata on an encoded picture from the information on the 360-degree video data; decoding the encoded picture on the basis of the information on the encoded picture; and rendering the decoded picture on the basis of the metadata, wherein the metadata includes group global coordinate system rotation structure information indicating information on a relative rotation angle between a common reference coordinate system and a global coordinate system of a viewpoint group included in the 360-degree video data.
