Definition - What does Super-video (S-Video) mean?
Techopedia explains Super-video (S-Video)
One of the benefits of S-video is a higher bandwidth than composite video technologies. However, although many consider S-video to be a step up from composite in terms of image quality, quality and compatibility can be issues with S-video, and users have to consider the full range of analog and digital video solutions in setting up a display infrastructure. For example, where SCART technology or other methods have largely replaced S-video on consumer products, it may be hard to use S-video in the average A/V connection.
