    Abstract: 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.

    Abstract: Provided are an on-channel repeater and a method thereof. The repeater receives signals on one channel and distributes the signals on the same channel by converting RF signals from a main transmitter into baseband signals; equalizing them in a high-performance equalizer; adding a repeater identifier to them; modulating the baseband signals with the repeater identifier into RF signals. The repeater includes: a receiver for receiving RF signals; a demodulator for demodulating the RF signals into baseband signals; an equalizer for equalizing the baseband signals; an adder for adding a repeater identifier to the baseband signals; a modulator for modulating the baseband signals with the repeater identifier added in the adder into RF signals; and a transmitter for transmitting the RF signals modulated in the modulator. The technology of the present invention is used to form an on-channel repeating network in an arbitrary transmission system including a digital television broadcasting system.
