S-Video To RCA Cables: How To Get The Best Out Of Them

Have you observed how the wires you connect from your DVD player to the TV have changed over the years? In the same way, lots of other devices have evolved for different reasons. Sometimes, these devices use different cables to improve image quality or other reasons. In this case, however, our interest is in converting video signals using S-video to RCA cables.

So, if you are not satisfied with the color resolution on your TV, you may need to replace your video cables. What if your video player has cables that do not match your TV-out port? You, therefore, need a suitable converter or adapter. Read on, then, to find some DIY ways of getting the best picture from DVD and other video players.

1. Can you convert S-Video to RCA?

The straight answer is yes. The most common means of video signal conversion is with an adapter.

But, what do S-Video and RCA mean? 

For starters, S-Video is short for separate videos. During operation, the composite video signal carrier transmits the brightness and chroma signal from your device separately.

On the other hand, RCA (Radio Corporation of America) is another signal carrier for transmitting audio and video.

The standard RCA cable has two ends. The RCA jack is on one end, sometimes called the female jack. While on the other, you have the RCA plug, also called the male plug.

In most cases, to convert S-Video to RCA, you need an adapter. These converters/adapters come with a female RCA jack and a male 4-pin S-Video plug.

You only need to plug one end of your VCR into the RCA adapter. At the same time, the other port on the RCA adapter goes to the four-pin S-Video connector of the AV receiver. 

Otherwise, use a bi-directional video cable. That way, it is easy to convert from S-video to the composite video signal and vice versa.

In general, these bi-directional S-video to RCA cables is most suitable for component connections. And they deliver better color graphics overall. 

How S-video to RCA cables work

How it works is quite simple. Mainly, S-Video divides the colors into separate signals of black and white.

So, the separate chroma and luma signals combine into one video signal in converting to RCA. Although the result is not the best signal quality, S-video to RCA cables is still widely-used video wires. Moreover, the loss of quality, in general, is barely noticeable. A typical viewer just wants to connect his DVD receiver output to the composite input of a TV set and enjoy.

You need an adapter to use S-video to RCA cables to do this. And most times, these S-Video signals to RCA input adapters are different. Yet, the most common type is the female/female adapters. These allow you to plug an RCA cable and a standard S-Video cable into their matching male connectors.

Another option includes using adapter cables. The configuration is a bit different, though. Unlike the usual wires, they have an RCA connector and an S-Video connector at opposite ends.

It is often not easy to find a suitable adapter cable for converting S-Video to RCA. Most times, the ones you see in stores are too short. Hence, It is crucial, to customize one yourself.

As an alternative, special adapters help convert Y/C video (S-video) to composite video. These adapters are helpful, especially in cases where your s-video devices have only one such output. Or, on the other hand, when your device has only a composite video input (RCA) as the signal input source. Overall, these adapters work great on NTSC and PAL video standards still.

3. S-Video to RCA cables FAQ

Due to different configurations on video devices, people need to convert videos from one source to another output. Hence, we introduce some frequently asked questions from both viewers and technophiles.

Are S-Video to RCA cables still in use?

Yes, these cables are still around. Although, newer technology use more advanced video technology these days. However, S-video to RCA cables is still crucial for older devices that support only composite video.

Are there other video cables apart from S-Video and RCA?

Apart from S-video and RCA, some digital video cables connect your PC and TV. The popular ones include HDMI, VGA, DVI, and Thunderbolt.

How do I convert other videos to S-video format?

You only need a suitable converter or adapter with matching ports for the cables. A digital-to-analog signal converter should work best if your VCR or TV supports only composite videos. 


In summary, both S-Video and RCA are analog video connections. They both transmit electrical signals to represent videos. However, they are of different quality and standards. S-video, sometimes tagged component video, produces a higher color resolution than composite video. 

Notwithstanding, there are many other video connection cables also available. So, if you are just setting up your devices and cables and need some professional assistance, our contact page is one click away.
