The paper introduces the principle and methods of the digital separation of Y and C signals for PAL composite television signal. The analyses of these methods and the comparison between them are made.
In Human Vision System, the optical signal is separated to brightness and chroma information, and they are processing differently. It is an important quality of Human Vision System.
