Data transport in unannounced standard caption service
View Patent ↗A method of processing disparity data for closed captions for three dimensional video involves receiving closed caption data including closed caption text within a first Standard service block having a service number in the range of 1-6; receiving closed caption disparity data within a Standard service block having a service number equal to n, where n is between 1 and 6; receiving a linkage field which associates each instance of said disparity data to a corresponding Standard service; parsing the disparity data from the closed caption data appearing in service number n; and processing the caption text and disparity data to produce an output suitable for defining a rendering of a three dimensional image on a display of the caption text at a z-axis position defined by the disparity data. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
1. A method of a reception apparatus for processing closed caption data, comprising:
receiving, by circuitry of the reception apparatus, audio, video, and closed caption data, the closed caption data including closed caption text in Standard caption Service #1 and additional data in Standard caption Service #6;
receiving, by the circuitry, caption service information that announces the Standard caption Service #1 and does not announce the Standard caption Service #6;
parsing the additional data from the closed caption data included in the Standard caption Service #6; and
outputting, by the circuitry, a presentation of the video data for display to a user of the reception apparatus based on the parsed additional data included in the Standard caption Service #6.
2. The method according to claim 1 , wherein the closed caption text is associated with the audio data.
3. The method according to claim 1 , wherein the additional data includes closed caption disparity data for displaying the closed caption text in the Standard caption Service #1.
4. The method according to claim 3 , wherein the closed caption disparity data includes a linkage field which associates the closed caption disparity data with the closed caption text in the Standard caption Service #1.
5. The method according to claim 1 , wherein the additional data are carried in a CEA-708 compliant variable length command.
6. The method according to claim 1 , further comprising:
outputting the closed caption text for display as a stereoscopic image in the presentation.
7. A non-transitory computer readable medium storing instructions that when executed by a computer causes the computer to perform a method for processing closed caption data, the method comprising:
receiving, audio, video, and closed caption data, the closed caption data including closed caption text in Standard caption Service #1 and additional data in Standard caption Service #6;
receiving caption service information that announces the Standard caption Service #1 and does not announce the Standard caption Service #6;
parsing the additional data from the closed caption data included in the Standard caption Service #6; and
outputting a presentation of the video data for display to a user of the reception apparatus based on the parsed additional data included in the Standard caption Service #6.
8. A reception apparatus, comprising:
circuitry configured to
receive, audio, video, and closed caption data, the closed caption data including closed caption text in Standard caption Service #1 and additional data in Standard caption Service #6;
receive caption service information that announces the Standard caption Service #1 and does not announce the Standard caption Service #6;
parse the additional data from the closed caption data included in the Standard caption Service #6; and
output a presentation of the video data for display to a user of the reception apparatus based on the parsed additional data included in the Standard caption Service #6.
9. The reception apparatus according to claim 8 , wherein the closed caption text is associated with the audio data.
10. The reception apparatus according to claim 8 , wherein the additional data includes closed caption disparity data for displaying the closed caption text in the Standard caption Service #1.
11. The reception apparatus according to claim 10 , wherein the closed caption disparity data includes a linkage field which associates the closed caption disparity data with the closed caption text in the Standard caption Service #1.
12. The reception apparatus according to claim 8 , wherein the additional data are carried in a CEA-708 compliant variable length command.
13. The reception apparatus according to claim 8 , wherein the circuitry is configured to:
output the closed caption text for display as a stereoscopic image in the presentation.
