The S-Video standard

The S-Video standard (for "Sony Video"), sometimes called Y/C, is a video transmission mode with separate components using different cables to carry information regarding luminance (luminosity) and chrominance (colour).

An S-Video connection makes it possible to offer an optimal video quality by simultaneously sending the 576 rows of the image, without interlacing (all at once).

The S-Video signal is usually transmitted using a cable which comprises a 4-pin mini-DIN connector (two distinct pins for each video component):

This type of connector is used in state-of-the-art video cameras or S-VHS video tape recorders, Hi8 cameras or quite simply on most graphics cards with TV output. However, the S-Video signal only allows the video signal to be transmitted, it is necessary to use a separate audio cable for the audio data transmission.

It should be noted however, that recent model Peritel sockets also allow S-Video signals to be transmitted. There are also adaptors which will allow an S-Video audio cable and RCA connectors to be connected to a Peritel socket, at the cost of additional signal degradation.

Nevertheless, since the S-Video signal was not part of the original Peritel socket specifications, some equipment with these sockets will not support this type of signal.
