A digital tuner equipped with a recording media reproduction device outputs digital content to an externally connected monitor device. The digital content includes digital content obtained by receiving a digital broadcast signal via a tuner and digital content previously recorded in a HD device and read therefrom. Whenever a user operates a remote controller to performs a common operation via a key to select and switch digital content to be output to the monitor device, digital content provided by a digital broadcast signal or that recorded in the HD device is sequentially selected. The selected digital content is obtained by the tuner or the HD device and provided to a decoder. The decoder receives and decodes the digital content and outputs it to the monitor device.
