Method for displaying 3D caption and 3D display apparatus for implementing the same

摘要

A 3D caption display method for harmoniously merging and displaying closed caption with 3D image in a 3D display apparatus, and a 3D display apparatus suitable for implementing the method. When the 3D display apparatus receives image signals of first and second images for implementing 3D image in a stereoscopic scheme, the 3D display apparatus receives closed caption data only for a base view determined from the first and second images. Then, the display apparatus determines the position of a closed caption for an extended view based on the closed caption data for the base view and a certain 3D caption information, and formats caption graphic data for the base view and the extended view to output 3D closed caption in a stereoscopic format.

主权项

1. A method for displaying a three-dimensional (3D) caption in a 3D display apparatus, the method comprising:
receiving a broadcast signal including 3D caption data based on a code space, wherein the code space contains base code sets and extended code sets; acquiring 3D command and caption text from the 3D caption data, wherein the 3D command is delivered in at least one extended code set, and wherein the 3D command specifies an amount of horizontal offset between left-and right-eye views for a caption window; and processing the 3D command and the caption text such that the caption text is written to the caption window for 3D captioning.
