Abstract

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.

Description

technical field [0001] The present invention relates to an apparatus and method for transmitting / receiving 3D stereoscopic digital broadcasting signals by using three-dimensional (3D) stereoscopic video additional data; in particular, to such a 3D stereoscopic digital broadcasting transmitting / receiving apparatus and method for transmitting / receiving 3D stereoscopic digital broadcasting by using 3D stereoscopic video additional data is defined and processed as an additional stream added to a 2D video transport stream to be compatible with a two-dimensional (2D) set broadcasting system, the apparatus and method are compatible with providing 3D stereoscopic digital video by using another viewpoint The traditional approach to broadcasting systems is different. The 3D stereoscopic video additional data includes another viewpoint video, inconsistency information and depth information. Background technique [0002] A digital broadcasting technology using Moving Pictures Experts G...
