Is S-Video still being used?

S-Video remains a useful option to anyone who has an older camcorder using the connection.

However, there are some instances where an S-Video input could be helpful. There are still legacy video components where S-Video is the highest quality connection–standard-definition cable boxes are a good example. S-Video remains a useful option to anyone who has an older model of camcorder that makes use of the connection. Instead of completely removing S-Video it is preferential that receivers have an S-Video connector located on the front panel.

The types of S-Video cables and their Applications


  • Coaxial Cables They are by far the most commonly used kind of cable that is used to connect audio and visual devices. The majority of homes have at the very least one coaxial jack when you have cable television services within your home it is this cable that connects your cable device to the service.
  • Component Cables Component cables are usually utilized for analog video.
  • composite cables These cables appear like component cables, in that they also feature RCA plugs on the ends. They are able to carry audio and visual information. 
  • Digital Coax Cables A digital coax cable can be employed to join your device to the CD player or DVD player. The cables feature an RCA interconnect at the top of the.
  • DisplayPort Cables Display Port cables were created in the Video Electronics Standards Association and are widely used in personal computers and electronic devices. These cables connect your source of the video to your screen, such as the computer monitor.
  • The three formats for DVI are available to select from: DVI-D, which is digital video in its true form DVI-A, which is high-resolution analog, and DVI, which is a blend of the two.
  • HDMI Cables HDMI Cables HDMI Cables transmit audio and video signals from the device you are using to television or monitor. They can simplify the process of connecting different devices by needing to connect only HDMI cable.
  • They do this by splitting the video information into a color and brightness signal.

What is the different between S-Video and Composite?

Composite video alters the format that an analog signal takes. The Y symbolizes luminance, while the U and V represent hue and saturation that is what makes up the chrominance. Thus, U and V together contain the information in the color signals.

It is an analog signal that transmits information in two distinct signals, specifically the chroma, which is color; and luma which refers to luminance. It transmits standard definition video over only one cable, and does not mix audio signals. S-video and Composite Video are two distinct types. S-video along with Composite Video differ from one another in a variety of aspects.

Functional differences and picture quality

A composite video signals is analog and transmits the video or image via a single, poor quality signal. For comparison, S-video transports the picture via two signals, specifically the color chroma (colour) and the luma (luminance). This video signal is superior quality than that which composite video offers.The luminance information is high-frequency. But S-video is able to keep both signals separated and this means that the act of low-pass filtering is not necessary.This improves image clarity, while conserving the information from the original video source.

Connectors for Composite and S-video

Both S-video and composite videos depend on analog-based video signals. Both work with PAL, NTSC, and SECAM codes. But their connectors differ from one another.

S-video signals generally use cables with a mini-DIN 4-pin connector, which is like the standard mini-DIN cables. Connectors’ prices are fairly reasonable, however, the pins’ quality are not great and they can bend in the course of long-term use.


S-video was more effective than composite video, but it was not as effective in comparison to component videos. The composite video had synch and video as well as the color combined on one line, so segregating it all hampered the quality.

Some TVs also are able to accept RGB inputs directly. This is most suitable for connecting to a computer whose graphics card also operates using RGB internally. This allows each pixel of the screen to be able to display a color independent of its neighbors.

In terms of traditional analog video connections, RGB component gives the highest quality image, YPbPr comes in close second S-video follows, and finally, composite. If you have the VHS recorder, you should use the S-video output, not that of the composite output.

However this doesn’t necessarily mean that a gadget with S-video output is of superior to a device that has composite output. This is the only outputs of one device that offers S-video as one its options. S-video has superior quality over composite.

But that may have certain exceptions. If you had a LaserDisc player as well as TV which both included composite and S-video connections it was possible to use either of the cables to connect to them.

If the TV’s circuitry was superior than the TV set, the composite cable will make use of the TV’s circuitry instead.
