Xintekvideo's Picture Quality Restorer Model HQ2000 is a state of the art signal processing system that essentially removes all electrical or ignition-type impulse noise from NTSC color television signals. In addition it significantly reduces random noise and other interference. It is particularly effective in reducing satellite or FM link threshold noise that normally appears as "sparkles" or streaks as well as thermal noise. It is, in effect, a means of extending threshold in FM links. The Model HQ2000 is also particularly useful for cleaning up off the air signals from distant TV stations.
