Digital video noise reducer is an optional submodule for use with the 8400 and 8500 video processing frame synchronizers. The noise reduction process is downstream from the 8400 or 8500 proc amplifier controls. The 8520 can be used with any video input source. It only adds 4 microseconds to the throughput delay of the 8400 or 8500, so it does not introduce problems with system timing. It is motion and scene-adaptive. It removes unwanted noise and artifacts, making it perfect for MPEG compression preprocessing and satellite or ENG feeds.
