Abstract
According to one aspect of the present invention, the present invention may relate to a method for transmitting a 360 video. The method for transmitting a 360 video may include processing a plurality of circular images captured by a camera having at least one fisheye lens; encoding a picture to which the circular images are mapped; generating signaling information about the 360 video data; encapsulating the encoded picture and the signaling information into a file, and transmitting the file.
Claims20
A method for processing at least one circular image in a digital transmitter, the method comprising:
- mapping the at least one circular image onto a picture in a video format;
- encoding the picture as a coded video bitstream;
- generating metadata which assists in rendering the picture,
- wherein the metadata includes rectangular region top/left information, rectangular region width information, rectangular region height information, circular image centre information and circular image radius information,
- wherein the rectangular region top/left information is used to represent a coordinate of a top-left corner of a rectangular region that contains the at least one circular image,
- wherein the rectangular region width information is used to represent a coordinate of an width of the rectangular region that contains the at least one circular image,
- wherein the rectangular region height information is used to represent a coordinate of a height of the rectangular region that contains the at least one circular image,
- wherein the circular image radius information is used to represent a radius of the at least one circular image that is defined as a length from the centre of the at least one circular image specified by the circular image centre information to the outermost boundary of the at least one circular image;
- and
- transmitting a signal including a coded audio stream, the coded video bitstream and the generated metadata.

A method for processing at least one circular image in a digital receiver, the method comprising:
- receiving a signal including a coded audio bitstream, a coded video bitstream and metadata from a digital transmitter;
- wherein the metadata includes rectangular region top/left information, rectangular region width information, rectangular region height information, circular image centre information and circular image radius information,
- wherein the rectangular region top/left information is used to represent a coordinate of a top-left corner of a rectangular region that contains the at least one circular image,
- wherein the rectangular region width information is used to represent a coordinate of an width of the rectangular region that contains the at least one circular image,
- wherein the rectangular region height information is used to represent a coordinate of a height of the rectangular region that contains the at least one circular image,
- wherein the circular image radius information is used to represent a radius of the at least one circular image that is defined as a length from the centre of the at least one circular image specified by the circular image centre information to the outermost boundary of the at least one circular image;
- decoding the coded video bitstream and the coded audio bitstream;
- stitching the decoded video bitstream based on the metadata to an omnidirectional image;
- rendering the omnidirectional image based on an user's viewport;
- and
- outputting video.

- wherein the rectangular region width information is used to represent a coordinate of an width of the rectangular region that contains the at least one circular image,
- wherein the rectangular region height information is used to represent a coordinate of a height of the rectangular region that contains the at least one circular image,
- wherein the circular image radius information is used to represent a radius of the at least one circular image that is defined as a length from the centre of the at least one circular image specified by the circular image centre information to the outermost boundary of the at least one circular image;
- a decoder configured to decode the coded video bitstream and the coded audio bitstream;
- a processor configured to stitch the decoded video bitstream based on the metadata to an omnidirectional image, and render the omnidirectional image based on an user's viewport;
- and
- a display configured to output video.
