"...The advent of High Definition Television (HDTV) has brought a longstanding problem into painful focus. Once a person purchases a HDTV they discover the quality of most of our standard definition (480i) sources are not very good. Most assume something is wrong with their new television, but unfortunately these high resolution devices bring our legacy broadcast system flaws into sharp focus. Whether you get your signal off-the-air (OTA) or from cable or satellite they are fraught with noise including compression artifacts and bad reception noise. Surprisingly OTA has fewer problems than the others, but programming selection is limited in comparison.
Algolith has created a new device to deal with this problem that won recognition as a CES 2005 Innovations Honoree in the Home Theater category. The Mosquito uses four different noise reducing techniques to improve the appearance of less than perfect source material. It can remove mosquito noise using Algolith's proprietary pixel based algorithm. Something called Block Artifact Reduction (BAR) reduces the block structures of compressed images found on any source that uses MPEG compression. Advanced motion adaptive temporal filtering is provided to eliminate bad reception and low light noise. Finally, the Mosquito provides image enhancement using non-linear filters to remove noise while retaining image details...." |
