This digital broadcast reception device (100) has: a first broadcast reception system (110); a second broadcast reception system (120); an audio similarity detection/processing unit (131); a service list storage unit (132); and a reception monitoring unit (133) that transmits a notification signal (G1) to the first broadcast reception system (110) when a value indicating the reception state of a channel tuned to by means of the first broadcast reception system (110) has decreased. When the first broadcast reception system (110) receives the notification signal (G1), the first broadcast reception system (110) refers to the value indicating the degree of audio similarity of the service list stored by the service list storage unit (132), thereby determining that the program of the channel that the first broadcast reception system (110) is tuned to is the same program as the most similar program, and the channel is switched to a channel determined to have the same program. |
