What is S-Video?

S-Video ( Separate video often referred to as "Super-Video") is the standard video interface that is now on most audiovisual devices. S-Video is a step up from a standard composite video that uses a yellow RCA connector and RCA cable, while S-Video uses a mini-din plug and a S-video cable. When connecting the device that has both options, you can choose to use S-Video connectors. To ensure the correct orientation of the pins, the connector has a guaranteed metal sleeve that must be inserted correctly with the female jack before insertion. S-video cables are more expensive than RCA cables and are not always included in products, but can be purchased separately.

S-Video brings an excellent image to a composite video by avoiding some processing that a composite video requires. The video signal is a mixture of two separate data streams: brightness or luminescence, known as y stream, and chrominance or color, known as the current c . SignThe C bears values ​​for red and blue, while green values ​​are derived. Therefore, RGB or red, green and blue occupies only two data streams within the C.

In the original used analog video standard from the age of 50. Y/C signals are compressed into a single current, they pass through a single RCA wire and decoded with a television filter to Y and C elements. This is translated directly into the screen when the image quality is lost. The S-Video retains greater signal integrity by placing two wires in a single housing and dedicating one of the Y and C signals and eliminating most of the filter process. Greater maintaining the integrity of the signal leads to a sharper image.

As with Composite Video, S-Video only transmits visual data. Sound cables are required for sound transfer. They can be a tentDard RCA cables or CD and DVD players can be preferred with digital audio connections.

There are people who claim that they do not see any significant difference between a composite video and S-Vide, while others believe that the transition from composite to S-Video is similar to getting the system at the cost of cable. Some of the uncertainties could be that in addition to HDTV, TV signals and VHS tapes, they are coded with a composite video. However, DVDs are coded using a higher standard, so improving image quality should be more evident when using S-Video to view DVDs. Before you run for S-Video cables, make sure your device supports either a component video or a HDMI multimedia interface that is better than S-Video.
