Abstract
The present invention suggests a method of providing subtitles for a 360 content, the method comprising: generating 360 video data captured by at least one camera; stitching the 360 video data; projecting the 360 video data to a 2D image; encoding the 2D image into a video stream; generating a 360 subtitle Supplemental Enhancement Information (SEI) message for signaling a subtitle for the 360 content; inserting the 360 subtitle SEI message into the video stream; and generating a broadcast signal including the video stream, and transmitting the broadcast signal.
Claims10
A method of providing at least one subtitle for 360-degree video data in a transmitter, the method comprising:
- generating the 360-degree video data captured by at least one camera;
- stitching the 360-degree video data;
- projecting the 360-degree video data to a 2D image;
- encoding the 2D image into a video stream;
- generating information for signaling the at least one subtitle for the 360-degree video data,
- wherein the information includes flag information for representing that text related to the at least one subtitle is visible when a user is looking in a specific direction or representing that the text related to the at least one subtitle is visible independently of a viewing direction of the user,
- wherein the information further includes region count information for representing the number of regions related to the at least one subtitle, and region identification (ID) information for providing an identifier of the regions related to the at least one subtitle;
- and
- transmitting the encoded video stream and the information.
A method of displaying at least one subtitle for 360-degree video data in a receiver, the method comprising:
- receiving the 360-degree video data and information for signaling the at least one subtitle for the 360-degree video data,
- wherein the information includes flag information for representing that the at least one subtitle is visible when a user is looking in a specific direction or representing that the at least one subtitle is visible independently of a viewing direction of the user,
- wherein the information further includes region count information for representing the number of regions related to the at least one subtitle, and region identification (ID) information for providing an identifier of the regions related to the at least one subtitle;
- and
- displaying the 360-degree video data with the at least one subtitle based on the information.
A transmitter of providing at least one subtitle for 360-degree video data, the transmitter comprising:
- a processor configured to generate the 360-degree video data captured by at least one camera, wherein the processor is further configured to stitch the 360-degree video data, project the 360-degree video data to a 2D image and generate information for signaling the at least one subtitle for the 360-degree video data,
- wherein the information includes flag information for representing that text related to the at least one subtitle is visible when a user is looking in a specific direction or representing that the text related to the at least one subtitle is visible independently of a viewing direction of the user,
- wherein the information further includes region count information for representing the number of regions related to the at least one subtitle, and region identification (ID) information for providing an identifier of the regions related to the at least one subtitle;
- an encoder configured to encode the 2D image into a video stream;
- and
- a transmitting module configured to transmit the encoded video stream and the information.
A receiver of displaying at least one subtitle for 360-degree video data, the receiver comprising:
- a receiving module configured to receive the 360-degree video data and information for signaling the at least one subtitle for the 360-degree video data,
- wherein the information includes flag information for representing that the at least one subtitle is visible when a user is looking in a specific direction or representing that the at least one subtitle is visible independently of a viewing direction of the user,
- wherein the information further includes region count information for representing the number of regions related to the at least one subtitle, and region identification (ID) information for providing an identifier of the regions related to the at least one subtitle;
- and
- a displaying module configured to display the 360-degree video data with the at least one subtitle based on the information.
