Claim Text:
1. A system for transmitting three dimensional (3D) video based on digital broadcasting, comprising: an encoder 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 packetizer 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 encoder; a program specific information (PSI) generator generating a PSI representing the 3D supplementary data; a transport stream (TS) generator generating a 2D video TS and a 3D supplementary TS for the 2D video PES and the 3D supplementary PES from the packetizer and a PSI TS for the PSI generated from the PSI generator; a multiplexer multiplexing the transport streams from the TS generator 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 modulator configured to modulate the multiplexed TS according to a specification of a digital television (DTV) and transmitting the modulated TS.
