Y/C Separation
User’s Guide
Introduction
Compro has always focused on developing products with great picture quality. Some
VideoMate TV models now feature Y/C Separation and digital noise reduction hardware for
unprecedented quality. This manual tells you how to optimize the Y/C separation settings to
the type of TV programs you care most about.
Y/C Separation
Television signals actually contain two signals, Luminance and Chrominance. By convention,
Y represents Luminance and C represents Chrominance. The Y signal describes the
brightness of the picture and C represents the color information. Black and white TV signals
contain only the Y signal. When color TV was introduced many years ago, the Y and C
signals were combined into a
composite
video signal. This has the advantages of being
compatible with black and white TV set and using less bandwidth. All TV sets must separate
the Y and C signals before presenting a picture.
This is analogous to using a glass prism to separate colors from a beam of white light.
