27
S-Video Connector
  • S-Video Connectors
  • 4-Pin mini din connector, separating video
    signals into 2 signals Y/C, chrominance (C)
    (color) and luminance (Y) (brightness) portions

    distortions encountered can be eliminated.

29
S-Video Signals
  • Chrominance
  • Chrominance is abbreviated with the letter C
  • The color portion of a video signal carrying the
    saturation and tint (hue) information for any
    given point in the image.

    or stronger colors

30
S-Video Signals
  • Luminance
  • Luminance is abbreviated with the letter Y.
  • The black and white portion of a video signal
    which carries the information for brightness and
    darkness and contrast. Luminance ranges from pure
    black to pure white. When combined with the color
    portion (chrominance), a complete video image can
    be developed.
