Summary:PURPOSE: A modulation method for transmitting additional data in a broadcast system and a device thereof are provided to transmit emergent additional data in a terrestrial wave digital television broadcast network. CONSTITUTION: An encoding unit encodes a broadcast stream. An additional data transmitting unit(310) encodes a channel of additional data. The additional data transmitting unit modulates the additional data by a set spreading method. An adding unit(305) combines an output of the encoding unit with an output of the additional data transmitting unit. A modulating and transmitting unit modulates and transmits an output of the adding unit according to transmission protocols of a broadcast system.
