Abstract:
A receiver for receiving a digital audio broadcast signal including digital audio data and control data incidental to the digital audio data, the receiver comprising:a reception circuit for receiving a digital audio broadcast signal; a decoder circuit for extracting digital audio data and control data from the digital audio broadcast signal received by said reception circuit; a D/A converter circuit for performing D/A conversion of the digital audio data extracted by said decoder circuit for producing an analog audio signal and for outputting the analog audio signal; control means for controlling a characteristic of the analog audio signal in accordance with the control data extracted by said decoder circuit; and a memory into which a one of the digital audio data and the control data which has been extracted at an earlier time by said decoder circuit is written, wherein said control means successively varies a write address for said memory in a sampling period of the digital audio data while said control means successively reads out the data written in said memory with a read address having a predetermined address different from the write address and uses the data thus read out to execute control of the characteristic of the analog audio signal with the control data extracted by said decoder circuit.
