Separate video cables or S video cables are used to transmit video data for standard definition monitors. Such S video cables, which transmit no audio signals, can be used for image reception at 480i or 576 resolution. Several consumer goods like DVD players, television, game consoles, and VCRs use S video cables. It is also possible to convert composite signals to S video by using a converter adapter. Three different cables – yellow, red and green - combine with each other to form a composite cable. These converter cables do not affect quality of images, and only enable incompatible devices to be connected with an S video
However, S video cables are not ideal for high definition video signals, as they require more bandwidth than these cables can carry. You can easily find S video cables in an electronic supply store or a computer supply store. Before buying such a cable, you must check the warranty that comes with it. S video cables are available in three different lengths, measuring 1.5 m, 3.05 m, and 6.1 m. It makes sense to purchase a cable which slightly exceeds the actual length you need to ensure that it does not pull on the connectors.
You should first compare various connection options and choose suitably from them. While connecting an S cable, ensure that the pins are locked completely into place before securing the cable. The cable is of no use if the pins are broken. Although HDMI cables have started getting popular, S video cables are still in demand.
