The Algogear™ VNR-1002-MD Video Noise Reducer utilizes several advanced noise reduction technologies to remove noise both as a pre-processor prior to encoding, or as a post-processor following decoding. When used as a post-processor, the VNR will correct any DCT-based compression artifacts such as mosquito noise and block artifacts, as well as many other types of random noise that result from analog to digital conversion, recording equipment or low-light captures. In addition, detail enhancement processing allows for image detail recovery without introducing halos or ringing.

The VNR-1002-MD dramatically increases picture quality and/or reduces bandwidth requirements while preserving image integrity for delivering content through cable, satellite, terrestrial networks, and IPTV delivery platforms. In addition, it allows for two channels to be processed simultaneously. This provides broadcasters with more channel processing density than any other solution available on the market today and significantly reduces their cost per channel.
