Disparity data transport and signaling

A method of setting a perceived z-axis position for a closed caption display region, comprising:

• receiving, by circuitry of an information processing apparatus, encoded dynamic closed caption disparity data that indicates the perceived z-axis position for the closed caption display region that changes for a sequence of video frames;
• receiving, by the circuitry, an encoded alternate closed caption disparity value that sets the perceived z-axis position for the closed caption display region to a predetermined fixed perceived z-axis position for the sequence of video frames;
• receiving closed caption text to be displayed in the closed caption display region;
• and
• determining, by the circuitry, a horizontal offset of left and right eye views of the closed caption display region that establishes the perceived z-axis position of the closed caption display region for the sequence of video frames based on one of the encoded dynamic closed caption disparity data and the alternate disparity value;
• further comprising:
• processing the closed caption text and the encoded dynamic closed caption disparity data to produce an output suitable for defining a rendering of an image with a display of the closed caption text at the perceived z-axis position defined by the encoded dynamic closed caption disparity data.

A non-transitory computer readable-medium storing instructions that when executed on one or more programmed processors carry out a process of setting a perceived z-axis position for a closed caption display region, the method comprising:

• receiving encoded dynamic closed caption disparity data that indicates the perceived z-axis position for the closed caption display region that changes for a sequence of video frames;
• receiving an encoded alternate closed caption disparity value that sets the perceived z-axis position for the closed caption display region to a predetermined fixed perceived z-axis position for the sequence of video frames;
• receiving closed caption text to be displayed in the closed caption display region;
• and
• determining a horizontal offset of left and right eye views of the closed caption display region that establishes the perceived z-axis position of the closed caption display region for the sequence of video frames based on one of the encoded dynamic closed caption disparity data and the alternate disparity value;
• further comprising:
• processing the closed caption text and the encoded dynamic closed caption disparity data to produce an output suitable for defining a rendering of an image with a display of the closed caption text at the perceived z-axis position defined by the encoded dynamic closed caption disparity data.

An information processing apparatus, comprising:

• circuitry configured to
• receive encoded dynamic closed caption disparity data that indicates a perceived z-axis position for a closed caption display region that changes for a sequence of video frames;
• receive an encoded alternate closed caption disparity value that sets the perceived z-axis position for the closed caption display region to a predetermined fixed perceived z-axis position for the sequence of video frames;
• receive closed caption text to be displayed in the closed caption display region;
• and
• determine a horizontal offset of left and right eye views of the closed caption display region that establishes the perceived z-axis position of the closed caption display region for the sequence of video frames based on one of the encoded dynamic closed caption disparity data and the alternate disparity value;
• wherein the circuitry is further configured to process the closed caption text and the encoded dynamic closed caption disparity data to produce an output suitable for defining a rendering of an image with a display of the closed caption text at the perceived z-axis position defined by the encoded dynamic closed caption disparity data.
