Saturation

The intensity of the colors in the active picture. The degree by which the eye perceives a color as departing from a gray or white scale of the same brightness. For example, red is highly saturated, whereas a pale pink is not. A 100 % saturated color does not contain any white, adding white reduces saturation.

Signal-to-noise (S/N) ratio

An S/N ratio can be given for the luminance signal, chrominance signal and audio signal. The S/N ratio is the ratio of noise to actual total signal, and it shows how much higher the signal level is than the level of noise. It is expressed in decibels (dB), and the bigger the value is, the crisper and clearer the picture and sound will be during playback.
