Abstract
Disclosed is a 360-degree video data processing method performed by a 360-degree video transmission apparatus, the method including: obtaining 360-degree video data captured by at least one camera; deriving a two-dimensional (2D) picture comprising omnidirectional image by processing the 360-degree video data; generating metadata for the 360-degree video data; encoding information on the 2D picture; and performing encapsulation based on the encoded information on the 2D pictureand the metadata, wherein the metadata comprises initial viewpoint ID information of viewpoint group which is related to the 360-degree video data.
Claims15
A 360-degree video data processing method performed by a 360-degree video transmission apparatus, the method comprising:
- obtaining 360-degree video data captured by at least one camera;
- deriving a two-dimensional (2D) picture comprising omnidirectional image by processing the 360-degree video data;
- generating metadata for the 360-degree video data;
- encoding information on the 2D picture;
- and
- performing encapsulation based on the encoded information on the 2D picture and the metadata,
- wherein the metadata comprises initial viewpoint ID information of viewpoint group which is related to the 360-degree video data.
A 360-degree video transmission apparatus processing 360-degree video data, the apparatus comprising:
- a data input unit configured to obtain 360-degree video data captured by at least one camera;
- a projection processor configured to derive a two-dimension (2D) picture including an omnidirectional image by processing the 360-degree video data;
- a metadata processor configured to generate metadata for the 360-degree video data;
- a data encoder configured to encode the information on the 2D picture;
- and
- an encapsulation processor configured to perform encapsulation based on the encoded information on the 2D picture and the metadata.
A 360-degree video data processing method performed by a 360-degree video reception apparatus, the method comprising:
- receiving information on 360-degree video data;
- obtaining information on an encoded picture and metadata from the information on the 360-degree video;
- decoding a picture based on the information on the encoded picture;
- and
- rendering the decoded picture based on the metadata,
- wherein the metadata comprises initial viewpoint ID information of a viewpoint group related to the 360-degree video data.
