METHOD AND DEVICE FOR TRANSMITTING 360-DEGREE VIDEO BY USING METADATA RELATED TO HOTSPOT AND ROI

摘要

A method by which a 360-degree video reception device processes 360-degree video data, according to the present invention, comprises the steps of: acquiring information on pictures of 360-degree videos at a plurality of view points and metadata on the 360-degree videos; decoding the pictures on the basis of the metadata and the information on the pictures and deriving an image for a first view point of a user; deriving a region of interest (ROI) for the first view point and a second view point on the basis of the metadata; and processing the image and the ROI on the basis of the metadata so as to render same by using a 3D space with the first view point as the center thereof, wherein the metadata includes information on a hotspot of the first view point and information on the ROI.
