PROBLEM TO BE SOLVED: To receive digital broadcast programs of different systems with a simple configuration and to easily confirm receptible broadcasting systems. SOLUTION: In this digital broadcast receiver, a CS digital broadcast module 10, a BS digital broadcast module 11, and a ground wave digital broadcast module 12 respectively reproduce reproduce digital signals in compliance with the MPEG 2-TS from respective received RF signals. In this case, synchronization detection circuits 20, 22, 24 discriminate whether of not the received signals are synchronous with each other, and when the synchronization detection circuits 20, 22, 24 discriminate that the received signals are not synchronous with each other, the synchronization detection circuits 20, 22, 24 stop output of a clock signal from clock output control circuits 21, 23, 25. When each of clock detection circuits 16 detects that the clock output control circuits 21, 23, 25 output the clock signals, the clock detection circuits 16 hold the clock signals and inform a received broadcast display section 17 about the fact of detection to allow the received broadcast display section 17 to display receptible broadcast systems. A selector 15 selects a digital signal from which a video/audio signal is reproduced.
