The tuner unit of a digital broadcast receiving apparatus receives a digital broadcast and generates a data stream from a digital broadcast signal having a desired modulation frequency. A data stream of a digital broadcast is also input from an external digital broadcast receiving apparatus via an external I/F. A stream switching unit and demultiplexer play back the content on a desired channel, contained in the two data streams, on an image display unit in real time, and at the same time, store the content on the other channel, contained in the other data stream, in a storage unit. This makes it possible to watch one of at least two programs with different modulation frequencies while recording the other program.
