Mosquito Noise Reduction

Video compression is a commonly used technique to squeeze more video content onto a disc, or beam down more channels via satellite, or transmit more channels over a cable. By using video compression content providers can achieve better economies of scale and offer the consumer more video content - e.g. more channels, bonus materials, etc. The problem with nearly all video compression methods is that too much of it causes compression artifacts. These artifacts are often seen by the viewer as ugly ringing around text letters or noise - often called mosquito noise.

To counter this Anchor Bay has developed a proprietary method of selectively removing mosquito noise and other compression induced artifacts. Unlike some methods of noise reduction that often makes the image worse by removing too much detail or causing blurring during motion, VRS Noise Reduction is designed to isolate the most objectionable of artifacts without removing detail or causing motion blur. To do this Anchor Bay had to devise a proprietary method of both isolating and predicting areas in the image where noise is likely to occur. The end result is a highly effective noise reduction method that is impervious to motion, yet, largely maintains the integrity of the detail in the image through our conservative approach in removing video compression artifacts.
