摘要：
A media processing system for limiting ringing in a filter output. A detection filter receives a media signal and generates a detection signal. The detection signal has a constant value over sections of the media signal having a consistent DC bias. The value of the detection signal changes when the DC bias of the media signal changes. The control module receives the detection signal and determines if the media signal may result in ringing based on the detection signal. If it is determined the media signal may result in ringing, a smoothing filter is applied to the media signal.
