Disparity Data Transport in Standard Caption Service

A method of 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 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 in 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.

A television receiver device that processes disparity data for closed captions, comprising:

• a receiver that receives closed caption data including closed caption text within a service block having a service number in the range of 1-6;
• the receiver further receiving closed caption disparity data within a Standard service block having a service number equal to n, where n is between 1 and 6;
• the receiver further receiving a linkage field which associates each instance of said disparity data to a corresponding Standard service;
• one or more processors that parse the disparity data from the closed caption data appearing in service number n;
• the one or more processors 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;
• and
• a compositor that receives and processes the disparity data and the caption text 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.
