Abstract: PURPOSE:To obtain a proper video signal in any reception state by discriminating the reception state so as to control noise elimination. CONSTITUTION:A band pass filter 7 extracts a PCM audio signal and it is fed to a digital audio data decoder 8. The digital audio data decoder 8 decodes an inputted PCM audio digital signal and gives its output to a D/A converter 9 and gives an error flag to a noise elimination circuit 10. The noise elimination circuit 10 counts the error flag and drives a high frequency noise elimination processing section when the count exceeds a prescribed value to eliminate high frequency noise. Thus, when the input signal quality is deteriorated and the S/N of the video signal is reduced, noise is eliminated automatically and ease to see video image is kept.
