ABSTRACT:
An arrangement for enhancing an image corresponding to a television signal including a digital component includes a variable bandwidth filter and a control unit for controlling the bandwidth of the filter in response to the bit error rate (BER) of the digital component of the television signal. The control unit increases the bandwidth as the BER and therefore the signal quality increases and decreases the bandwidth as the BER and therefore the signal quality decreases. In one embodiment, the control unit is responsive to both the BER and the "darkness" of the image represented by the television signal so as to restrict the bandwidth more for relatively dark areas than for relatively light areas.
