What makes this particular product interesting is that they filter the static parts of the image and the moving parts separately. So, for example, tuning out mosquito noise and reducing macroblocking in fast-moving scenes are two separate filter settings. So you can reduce macroblocking, which will cause some loss of detail of the fast-moving objects, but at the same time, not affect the sharpness of the rest of the image. In spite of Craig's continued protestations, it looks like this is used exactly as they claim, and exactly as I first thought. It is used by the broadcast station to process its compressed individual multicast streams before they are combined in the multiplex. The VNR-1000-HD, or its SD cousin, can take in either compressed or uncompressed digital inputs. Suggest reading the manual, especially the last half of it, where they give suggestions for how much filtering to dial in. http://www.algolith.com/fileadmin/user_upload/broadcast/3031-8001UG-200. pdf Bert ---------------------------------------------------------------------- You can UNSUBSCRIBE from the OpenDTV list in two ways: - Using the UNSUBSCRIBE command in your user configuration settings at FreeLists.org - By sending a message to: opendtv-request@xxxxxxxxxxxxx with the word unsubscribe in the subject line.
