The red, yellow, and white cables are called the RCA or composite cables. Many people call them the red, yellow, white cable for easier understanding. You can use the following names to refer to the cable:. Composite cables were designed in the s and are still relevant today. At some point, they were the standard for connecting electronic machines. The HDMI cable replaced them, but they are still in use. So, why RCA? RCA is an abbreviation for Radio Corporation of America that was the first company to produce the cables.
The RCA cables are available in many different colors, but the most prevalent combination is the red, white, yellow cable. Even though the RCA connectors were the standard for connecting media devices in the past, they are being gradually phased out. They are out-of-date but critical for connecting older media devices to modern display units. The component colors make it easy for the users to connect the cables to the TV ports, which are also coded. You only need to match the colors, and you are good to go.
But, what do the colors mean? Every color in the component cable colors has a particular purpose. Here is a breakdown of what they stand for:. The most prevalent RCA colors found in a home setting are red, yellow, and white. Composite video means that the three video signals red, green, and blue are relayed in one cable.
Red and white represent audio for the right and left speakers, respectively. How do you connect an old media device to a new TV or monitor? Why are the cables colour-coded? And what does each cable do? Why does the device need three separate cables? Identifying these cables can be a little confusing because they go by several names.
To start, the cables are called RCA or composite cables. Most people simply refer to them as red, white, and yellow cables, which is easier to understand. These connectors were designed all the way back in the s and are still in use today.
Once, they were the standard for connecting electronic devices. Why the name RCA? This is known as YPbPr component video. Component and composite audio-visual connection cables both transmit video via an analog signal. Old-style composite cables are no longer supported by most devices.
The newer component cable format was designed to work with modern high-definition devices. However, even component cables have had their day — high-resolution HDMI is now typically the connection of choice for the latest generation of audio-visual equipment.
Because the video signal is forced to travel through a single cable it is heavily compressed, losing much of its resolution and picture clarity.
The cables also suffer from radio frequency interference, which further degrades picture quality. When given the option, go for component over composite every time because this connection will always provide a better picture at higher resolutions.
The only practical use for composite video today is when using older equipment, such as older video game systems or VCRs, which do not support the component video format. Because of this, some new HDTVs include at least one composite video input to make them compatible with old equipment.
Component video splits the video signals into three cables — green, blue and red — with each transmitting a specific component of the video signal. The green cable also called Y transmits the brightness information of the signal. Plug the other end of the component cables into the corresponding, color-coded input jacks on the rear of the HDTV. Component video splits the video signals into three cables — green, blue and red — with each transmitting a specific component of the video signal.
The green cable also called Y transmits the brightness information of the signal. Look for component inputs on your TV. Look for a set that has a green input with yellow around it, or the word video just above or below it. RGB is an analog Video Component. RGB usually comes with 15 pin connections.
YPbPr uses only three separate cables.
