SNOW
A general term used to describe interference on a TV or video image. Snow in video is synonymous with chroma and Luma noise. It often manifests itself in a video picture as colored or black and white dots. Snow can result when the chrominance in the video signal is weak or oversaturated, when the signal is over-enhanced, when the video head is dirty or due to a host of other reasons. Good video processors reduce or eliminate snow.
