APPARATUS AND METHOD FOR TRANSMITTING/RECEIVING 3D STEREOSCOPIC DIGITAL BROADCAST SIGNAL BY USING 3D STEREOSCOPIC VIDEO ADDITIONAL DATA

摘要

Provided are a three-dimensional (3D) stereoscopic digital broadcasting transmitting/receiving apparatus and method using 3D stereoscopic video additional data. The apparatus and method is compatible with a two-dimensional (2D) digital broadcasting system by defining and processing 3D stereoscopic video additional data, such as another 3D video, disparity information, and depth information, as an additional stream added to a 2D video transport stream, which is different from the conventional method that provides a 3D stereoscopic digital broadcasting system by using video of another viewpoint. The 3D stereoscopic digital broadcast transmitting apparatus includes: a video acquiring unit; an audio data acquiring unit, an encoding unit, a program specific information (PSI) generating unit, a packetizing unit, a transport stream (TS) generating unit, a multiplexing unit, and a modulating unit.
