This digital broadcast recording device includes a tuner unit, a channel table recording unit, an image output unit, an OSD generation unit, an actuation unit, and a channel presetting unit. The channel table recording unit records a channel table. An auto presetting unit sets virtual channels. If the number of a virtual channel is duplicated upon several physical channels, the channel presetting unit commands the OSD generation unit to display an OSD to the effect that this number is duplicated. And, when the actuation unit has received a predetermined actuation input, the channel presetting unit searches for a vacant channel. |
