ABSTRACT:
A broadcast receiving apparatus includes an NIM having a digital terrestrial wave processing unit for processing a received broadcast signal as required for digital terrestrial broadcast and a digital cable processing unit for processing a received broadcast signal as required for digital cable broadcast, and a signal acquisition determining circuit for determining whether a received broadcast signal is for digital terrestrial broadcast or digital cable broadcast, based on waveform characteristic of the received broadcast signal. A CPU causes selected one of the digital terrestrial processing unit and the digital cable processing unit of the NIM to execute the signal processing, based on acquisition result information of the signal acquisition determining circuit.
