Method and apparatus for generating a broadcast bit stream for digital broadcasting with captions, and method and apparatus for receiving a broadcast bit stream for digital broadcasting with captions
A method of generating a broadcasting bitstream for a digital caption broadcast, the method including: receiving video data in which a video including at least one of a two-dimensional (2D) video and a three-dimensional (3D) video is encoded; determining caption data for reproduction in conjunction with the video, and 3D caption converting information including information relating to a converting speed of an offset for reproducing the caption data as a 3D caption; and outputting a bitstream for a digital broadcast by multiplexing the received video data, the determined caption data, and the determined 3D caption converting information.
