PROBLEM TO BE SOLVED: To provide a digital broadcasting receiver that can inform a user about a deteriorated reception state, before the occurrence of a frozen image or the like. SOLUTION: A demodulation circuit 8 generates information about error correction frequency of occurrence and gives the information to a CPU 23. The CPU 23 acquires noise strength data, on the basis of the information about error correction frequency of occurrence, in collation with the noise strength data corresponding to the error correction frequency of occurrence stored in a memory 24. The CPU 23 gives the acquired noise strength data to a digital/ analog converter 17. The digital/analog converter 17 gives a noise control voltage to voltage controlled amplifiers 12, 13. The voltage-controlled amplifiers 12, 13 adjust the strength of noises generated from noise sources 10, 11, an adder 14 superimposes the noises to an audio signal and an adder 15 superimposes the noises onto a video signal.
