摘要

A 360-degree video data processing method executed by a 360-degree video transmitting apparatus according to the present invention comprises a step of obtaining 360-degree video data captured by at least one camera, and a process of processing the 360-degree video data and projecting the 360-degree video data. A step of obtaining a picture (projected picture), a step of applying a region-wise packing to the projected picture to obtain a packed picture, and the 360-degree video data Generating metadata relating to the packed picture, encoding the packed picture, and performing processing for storing or transmitting the encoded picture and the metadata. The packed picture has at least one Region-wise Auxiliary Information (RAI) area for the target region of the packed picture, and the metadata includes information indicating the type of the RAI area. It is characterized by having. [Selection diagram] Fig. 9b
