Short for "Separate Video," S-Video is a type of analog video interface that produces a higher-quality signal compared to composite video. The signal is split into two separate channels- luminance (Y) and chrominance (C). Sometimes referred to as "Y/C video" or "Y/C", the connectors typically contain 4-pins within a single connection housing and are commonly found on consumer DVD players, VCRs, game consoles, and related devices.
