Provided is a 360-degree image data processing method performed by a 360-degree video reception apparatus. The method includes receiving 360-degree image data, obtaining information on an encoded picture and metadata from the 360-degree image data, decoding a picture based on the information on the encoded picture, rendering the decoded picture and an overlay based on the metadata, in which the metadata includes overlay related metadata, the overlay is rendered based on the overlay related metadata, the overlay related metadata includes information on an alpha plane of the overlay, and the information on the alpha plane of the overlay is included in a image item or a video track.

The present invention relates to a 360 video, and more particularly, to a method and apparatus for overlay processing in a 360 video system.
Virtual reality (VR) system provides a user with sensory experiences through which the user may feel as if he/she were in an electronically projected environment. An Augmented Reality (AR) system overlay a three-dimensional (3D) virtual image on an actual image or background of a real word, thereby allowing a user to feel as if the user is placed in an environment where a virtual reality and the real word are mixed. A system for providing VR may be further improved in order to provide higher-quality images and spatial sound. The VR or AR system may enable the user to interactively enjoy VR or AR content.
The present invention provides a method and apparatus for processing 360-degree video data.
FIG. 1 is a diagram showing an overall architecture for providing 360 contents according to an embodiment of the present invention.
FIGS. 2 and 3 are diagrams illustrating the structure of a media file according to an aspect of the present invention.
FIG. 4 is a diagram illustrating the overall operation of a Dynamic Adaptive Streaming over HTTP (DASH)-based adaptive streaming model according to an embodiment of the present invention.
The present invention may be modified in various forms, and specific embodiments thereof will be described and illustrated in the drawings. However, the embodiments are not intended for limiting the invention. The terms used in the following description are used to merely describe specific embodiments, but are not intended to limit the invention. An expression of a singular number includes an expression of the plural number, so long as it is clearly read differently. The terms such as “include” and “have” are intended to indicate that features, numbers, steps, operations, elements, components, or combinations thereof used in the following description exist and it should be thus understood that the possibility of existence or addition of one or more different features, numbers, steps, operations, elements, components, or combinations thereof is not excluded.
On the other hand, elements in the drawings described in the invention are independently drawn for the purpose of convenience for explanation of different specific functions, and do not mean that the elements are embodied by independent hardware or independent software. For example, two or more elements of the elements may be combined to form a single element, or one element may be divided into plural elements. The embodiments in which the elements are combined and/or divided belong to the invention without departing from the concept of the invention.
Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the attached drawings. Hereinafter, the same reference numbers will be used throughout this specification to refer to the same components and redundant description of the same component may be omitted.
