Patent ID: 8760498

Claim:
A method for processing disparity data for closed captions for three dimensional video, comprising: receiving closed caption data including closed caption text within a first Standard service block associated with a first Standard caption service having a service number in the range of 1-6; receiving closed caption disparity data within a second Standard service block associated with a second Standard caption service having a service number equal to 6; parsing, by circuitry of a reception apparatus, the disparity data from the second Standard caption service having the service number 6, the disparity data including a linkage field which associates said disparity data with the first Standard caption service; processing, by the circuitry of the reception apparatus, the caption text and the disparity data to produce an output suitable for defining a three dimensional television display of the caption text at a z-axis position based on the disparity data; where the disparity data are carried in a CEA-708 compliant variable length command; and displaying the closed caption text as a stereoscopic image.
