Patent ID: 8483269

Claim:
A system for transmitting three dimensional (3D) video based on digital broadcasting, comprising: an encoding means for generating two dimensional (2D) video elementary stream (ES) and 3D supplementary data elementary stream (ES) by independently encoding 2D video and 3D supplementary data, wherein the 2D video data includes images of a 2D viewpoint, and each image of the 3D supplementary data is from a viewpoint that is different than the 2D viewpoint; a packetizing means for generating a 2D video packetized ES (PES) and a 3D supplementary PES by independently packetizing the 2D video ES and the 3D supplementary ES generated at the encoding means; a program specific information (PSI) generating means for generating a PSI representing the 3D supplementary data by defining a packet identifier (PID) value and a program map table (PMT) for the 3D supplementary data to transmit the 3D supplementary data as a robust stream; a transport stream (TS) generating means for generating a 2D video TS and a 3D supplementary TS for the 2D video PES and the 3D supplementary PES from the packetizing means and a PSI TS for the PSI generated from the PSI generating means; a multiplexing means for multiplexing the transport streams from the TS generating means to transmit the 2D video TS as a normal stream and to transmit the 3D supplementary TS, the PSI TS and a 3D video synch data TS as a robust stream; and a modulating means for modulating the multiplexed TS according to a specification of a digital television (DTV) and transmitting the modulated TS.
