Abstract
A 360-degree video data processing method performed by a 360-degree video reception apparatus, according to the present invention, comprises the steps of: receiving 360-degree video data for a plurality of views; deriving metadata and information on a packed picture; decoding the packed picture based on the information on the packed picture; deriving a specific packed region for a target view from the packed picture based on the metadata; deriving a projected picture of the target view based on the specific packed region and the metadata; and rendering the projected picture based on the metadata, wherein the metadata includes multiview region-wise packing information, and wherein the multiview region-wise packing information includes information about a packed region in the packed picture and information about the target view.
