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

摘要

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 2-dimensional (2D) video and a 3D video is encoded; determining caption data to be reproduced with the video, and 3D caption converting information including information about 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 video data, the caption data, and the 3D caption converting information.
