Patent ID: 8878913

Claim:
A method of transporting data within a DTV bit stream, comprising: in a stream of digital video closed caption data packets, receiving closed caption text and a two bit extended packet control field; where the closed caption text and the two bit extended packet control field reside in a CEA-708-D compliant cc_data( ) data structure, with the two bit extended packet control field occupying two of the four consecutive reserved bits in the four bit reserved field imbedded in the for-loop of the CEA 708-D compliant cc_data( ) data structure; where the two bit extended packet control field has a value that designates that the information in cc_data — 1 and cc_data — 2 fields of the digital video closed caption data packets contain extended channel packets within the digital video closed caption data packets; receiving the extended packets within the digital video closed caption data packets in the cc_data — 1 and cc_data — 2 fields that carry extended channel data; where the meaning of the cc_data — 1 field can take on one of a reserved field, a start of an extended data packet, extended packet data and padding based upon the value of the extended packet control field; where the extended packet further comprises an extended command tag that designates that the extended packet contains caption disparity data; where the meaning of the cc_data — 2 field can take on one of a reserved field, extended packet data and padding based upon the value of the extended packet control field; outputting a video signal for display on the three dimensional display such that the closed caption text is positioned on the Z axis at a position designated by the disparity data.
