S-video is an older video format standard that was used on some equipment, such as the Atari 800 back in the 1970s. Now days, it is really not seen or used except for on old laptops. The video format can handle 480i or 576i in most cases and did not carry audio at all. This made it somewhat inconvenient, especially once composite cables and others were able to be better integrated. FireFold S-Video adapters are made to the highest quality standards and comes with the FireFold lifetime warranty, so they're great for integrating your older equipment with your current setup.
