A first demodulation unit of a digital broadcast reproduction system extracts signals for a plurality of channels from broadcast waves input to a radio receiver, subjects the signals to analog-to-digital conversion, and temporarily stores the data in a multichannel buffer. A second demodulation unit reads, from the multichannel buffer, digital data for a selected channel corresponding to a channel selection signal input from a controller operated by a user to a channel selection acknowledging unit. The unit subjects the data thus read to the remainder of the demodulation process so as to generate a data stream. A decoding unit 48 decodes the data stream and the image data thus obtained is displayed on a display unit of a television set.
