    Abstract: A tuner included in a digital broadcast receiver tunes a broadcast signal from a transmitter via a re-transmitter. A demodulator demodulates the broadcast signal, and an identification information detector detects identification information of a re-transmission service provided by the re-transmitter from the demodulated broadcast signal. A decoder arranged to decode the modulated broadcast signal, and a controller controls operation of the decoder based upon the identification information detected by the identification information detector. The identification information of the re-transmitter may directly include information identifying a type of the re-transmission service (e.g., a free or charged service) or may include a unique ID number of the re-transmission service, which could be used by the broadcast receiver to determine service type.
