The present invention relates to a method and apparatus for transceiving a broadcast signal in a digital broadcast system. The method for transmitting a broadcast signal according to one embodiment of the present invention comprises the following steps: generating a main signal using main data; generating an additional signal, the power of which is lower than that of the main signal, using a plurality of additional data; generating an additional signal frame using the additional signal and a frame header; and generating a broadcast signal using the main signal and an additional signal frame. The frame header is used in selectively extracting the plurality of additional data from the additional signal frame. According to the present invention, additional data can be efficiently transmitted while maintaining compatibility with existing digital broadcasting systems.
