2 S-Video Cable

3 Pass Out the S-Video Cable

4 Two Major Parts for Pictures Chrominance, or Chroma -- The portion of the video signal that represents color Chrominance, or Chroma -- The portion of the video signal that represents color If so used, it would produce a colored image but all the colors would be the same intensity If so used, it would produce a colored image but all the colors would be the same intensity Luminance, or Luma -- The portion of a video signal that represents brightness Luminance, or Luma -- The portion of a video signal that represents brightness The luminance signal is sufficient to produce a full black and white image The luminance signal is sufficient to produce a full black and white image

5 TV History Originally black and white (monochrome) Originally black and white (monochrome) Contained no color information Contained no color information High resolution within 25Hz-5MHz frequency range High resolution within 25Hz-5MHz frequency range Color TV was invented Color TV was invented TVs use comb filters to separate the color and brightness components of a video signal TVs use comb filters to separate the color and brightness components of a video signal

6 History Cont’ Sacrificed some resolution to retain compatibility with monochrome sets Sacrificed some resolution to retain compatibility with monochrome sets Color information added to monochrome by modulating sub-carrier Color information added to monochrome by modulating sub-carrier Loss of resolution after color addition is 50% (5MHz down to 2.5MHz) Loss of resolution after color addition is 50% (5MHz down to 2.5MHz)

7 S-Video Background introduced in the 1980s introduced in the 1980s Invented to eliminate the comb filter in TVs Invented to eliminate the comb filter in TVs Accommodated High-end S-VHS, Hi 8, and DV Camcorders because no improvement in resolution can be gained without changing TVs radically Accommodated High-end S-VHS, Hi 8, and DV Camcorders because no improvement in resolution can be gained without changing TVs radically

8 What is S-Video? An encoded video signal which separates the brightness from color data An encoded video signal which separates the brightness from color data also called Y/C (luminance and Chrominance) also called Y/C (luminance and Chrominance) One of the high quality methods of transmitting a television video signal One of the high quality methods of transmitting a television video signal

9 What is it used for? To improve the picture when connecting TVs to any high quality video source To improve the picture when connecting TVs to any high quality video source To maintain high resolution by keeping the luminance separate from the Chrominance To maintain high resolution by keeping the luminance separate from the Chrominance To provide less processing of the picture by bypassing the comb filter To provide less processing of the picture by bypassing the comb filter

10 How does it work? Transfers the maximum/all video signal data from source to TV Transfers the maximum/all video signal data from source to TV Separates the color and brightness parts of a composite-video signal (using hardware) Separates the color and brightness parts of a composite-video signal (using hardware) Keeps all signal data separate from source to TV to retain the high frequencies responsible for detail in the Luminance Keeps all signal data separate from source to TV to retain the high frequencies responsible for detail in the Luminance

11 Pass Out the S-Video to RCA Converter & “Y” Adaptor

12 Composite

13 S-Video

14 S-Video Port Pin Out

15 Uses Hi-8 Video VHS/S-VHS Video Dreamcast, GameCube, PS2, XBOX Video Connections PC Out - GeForce, ATI and many laptops

16 Advantages/Disadvantages Maintains high resolution Maintains high resolution Complete original video frequency range (25-5MHz) Complete original video frequency range (25-5MHz) No compromising quality due to length of cable No compromising quality due to length of cable 75 Ohm co-axial cable like other video signals 75 Ohm co-axial cable like other video signals Cost is higher Not a complete standard Transmits no audio

17 Pass All Examples Back Up Please S-Video cable S-Video cable S-Video Converter with Composite S-Video Converter with Composite S-VHS ‘Y’ Adaptor S-VHS ‘Y’ Adaptor
