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.
Claims20
A method of providing at least one subtitle for 360-degree video data in a digital transmitter, the method comprising:
- generating the 360-degree video data captured by at least one camera;
- encoding the 360-degree video data into a video stream;
- encoding audio data into an audio stream;
- generating metadata for signaling the at least one subtitle for the 360-degree video data,
- wherein the metadata 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 video stream, the audio stream and the metadata.
A method of displaying at least one subtitle for 360-degree video data in a digital receiver, the method comprising:
- receiving the 360-degree video data, audio data and metadata for signaling the at least one subtitle for the 360-degree video data,
- wherein the metadata 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;
- outputting the audio data;
- and
- displaying the 360-degree video data with the at least one subtitle based on the metadata.
A digital transmitter of providing at least one subtitle for 360-degree video data, the digital transmitter comprising:
- a processor configured to generate the 360-degree video data captured by at least one camera and generate metadata for signaling the at least one subtitle for the 360-degree video data,
- wherein the metadata 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;
- a video encoder configured to encode the 360-degree video data into a video stream;
- an audio encoder configured to encode an audio stream;
- and
- a transmitting module configured to transmit the video stream, the audio stream and the metadata.
A digital receiver of displaying at least one subtitle for 360-degree video data, the digital receiver comprising:
- a receiving module configured to receive the 360-degree video data, audio data and metadata for signaling the at least one subtitle for the 360-degree video data,
- wherein the metadata 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 outputting module configured to output the audio data;
- and
- a displaying module configured to display the 360-degree video data with the at least one subtitle based on the metadata.
