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, wherein the at least one extended code set is accessed by using an ‘EXT1’ code in a base code set, wherein the 3D command provides 3D information of a caption window; and processing the 3D information and the caption text such that the caption text is written to the caption window for 3D captioning.
