PROBLEM TO BE SOLVED: To provide a terrestrial digital audio broadcast receiver capable of concurrently receiving audio data or the like and VICS information transmitted on a physical channel selected by a user. SOLUTION: A terrestrial digital audio broadcast receiver comprises: a down-converter 8 which converts OFDM signals transmitted on all physical channels into intermediate frequency signals and outputs the intermediate frequency signals; an OFDM demodulation section 9 for demodulating all transport streams contained in the intermediate frequency signals; a filter 10 to which all the transport streams are inputted and which outputs a first transport stream transmitted on a physical channel selected by a user and a second transport stream on which VICS information transmitted on a predetermined physical channel is multiplexed; an audio decoding section 13; and a VICS decoding section 15.
