Abstract: PURPOSE: A data coding method for a 3D broadcast and a device thereof are provided to enable a user to watch a 3D broadcast while watching an existing 2D broadcast in a broadcast system. CONSTITUTION: An audio encoder(204) receives a voice signal. The audio encoder encodes the inputted voice signal using a voice signal compression algorithm. The audio encoder transfers the encoded signal to a multiplexer(206). The multiplexer multiplexes image signals encoded by a right image encoder(200) and a left image encoder(202), a voice signal encoded by the audio encoder, control data, and sub data. The multiplexer generates a transport stream.
