S-Video commonly termed Super-Video or Separate Video is a signal standard for video, generally 480i or 576i. Separating black-and-white and color signals promotes a higher image quality than composite video; however color resolution is lower than component video. S-Video cables typically have four-pin connector types, but may also include seven-pin and nine-pin connectors. The seven-pin mini-DIN connector is non-standard and is generally used with computer equipment. A nine-pin connector on the other hand is applied in graphics systems that have an input video and an output as well.
