and component video. This mid-level format divides the signal into two channels - luminance and chrominance. S-Video Signal and Cables The luminance signal and modulated chrominance subcarrier information are carried on separate synchronized signal/ground pairs.In composite
video, the luminance signal is low-pass filtered to prevent crosstalk between high-frequency luminance information and the color subcarrier. S-Video, however, separates the two, so low-pass filtering is not necessary. This increases bandwidth for the luminance information, and also subdues the color crosstalk problem. While the luminance performance of S-Video compares favorably to analog component video, the chrominance performance—aside from reduced crosstalk—does not show notable
improvement over composite video. S-Video signals tend to degrade considerably when transmitted across more than 5 meters of cable. For long distances, component or composite video may provide better quality. S-VIDEO ConnectorsStandard S-Video Cable Connector

standard S-Video cable connectorToday, S-Video signals are generally connected using 4-pin mini-DIN connectors using a 75 ohm termination impedance. The pins in the connectors bend easily, hence care must be taken when plugging the cables in--else a pin is likely to bend, causing the loss of color, corruption of the signal, or complete loss of the signal.Before the mini-DIN plug became standard, S-Video signals were often carried through different types of plugs. For example, the Commodore
64 home computer of the 1980s, one of the first widely available devices to feature S-Video output, used an 8-pin standard size DIN plug on the computer end and a pair of RCA plugs on the monitor end. Today, S-Video signals can be transferred through SCART connections as well. However the SCART connector must explicitly support S-Video as it is not part of the original SCART standard. S-Video Usage
S-Video is commonly used on consumer DVD players, VTRs, and modern game consoles. It is also available on some professional equipment and computer video capture and playback cards. Shop OnlineExperience S-Video Cable Manufacturing at its Best E-Mail, Request a Quote, or Call us Today |
