The 8520 Digital Video Noise Reducer is an optional sub module for use with the 8500 Video Processing Frame Synchronizer. The noise reduction process is downstream from the 8500 Proc Amp controls. The 8520 can be used with any video input source. It only adds 4 microseconds to the throughput delay of the 8500, so it does not introduce problems with system timing. The 8520 is motion-and scene-adaptive. It removes unwanted noise and artifacts, making it perfect for MPEG compression preprocessing and satellite or ENG feeds.
