YPbPr Vs. AV

Visual data being converted into transferable signals helps in feeding the audio and video devices such as televisions. These signals can be either analog or digital. Researchers have never rested in finding better ways to transfer signals. The advances did lead to better and better picture quality, which almost resembles the real-life picture. Understanding each signal type and what technologies they have to offer will provide better insights into the connectivity aptitude.

Analog Signals

Analog signals were used in older video devices, whereas the new ones use digital signals. Advanced devices carry ports for both signals and feature several ports offering you the flexibility of choosing the cables. A home theatre has two varieties of analog ports.

  • Composite: These RCA cables contain a yellow connector designated for video and the remaining white and red connectors for the audio. RCA cables are AV cables that can render both audio and video using a cable with three pins.
  • Component: The YPbPr Components three pins which use one pin for brightness and the rest two for color. It uses the red and white audio pins that are separate from the above mentioned three pins.

The analog signal using composite cables is now obsolete in many devices. However, the Component cable type still works excellently with modern devices of high-definition.

Check various ports well explained here:

YPbPr Vs. AV

Composite (AV or RCA)Component (YPbPr)
The single plug video transfer is no longer useful for modern devicesTransfers video using three plugs
It is not progressive and cannot render HD contentIt supports HD content and capable of displaying clear images
Forcing video through a single cable needs heavy compression leading to loss of clarityDividing the cables gives ample traveling space where the details are retained well and provide a high-resolution picture
Suitable for older devices, video games, VCRs, and similar vintage equipmentSome old devices do not support component technology

Since all the novel devices are turning HD, the composite video technology is now outdated, as you can see from the YPbPr Vs. AV table, AV cables of composite type do not have much to offer to modern gadgets. Among the analog signal wires, only component technology-based cables are competent enough to provide high resolution. Do not throw away your composite cables as they are still useful on older equipment, and you might never know when you may need them.

The above specified short comparison gives you an overall idea of what you are about to know in more detail below.

YPbPr Vs AV 03


Composite Cables

Be it the three cable analog connection or a single connector loaded digital connection; they can produce HD output. Though analog signals might be enough for a decent resolution, the flat-screen TV’s with digital signals make a hell lot of difference in rendering spectacular realistic views. The interference of signal issue for analog type does degrade picture quality every now, i.e., whenever you run electric devices or electrostatic devices. Radio Corporation of America (RCA) created these cables and hence the name. Since then, the AV cables were composite AV cables or RCA.

Component Video Cable

Though it contains three pins, all three of them are dedicated to audio. This cable splits the video signal to allow an easy flow of information. As each of them carries different information related to the video, if any of them is not inserted correctly, then you will miss that pins function not being displayed in the video—the significant difference between YPbPr Vs. AV is the compressed signal, which loses data in AV but not in YPbPr cables.

The YPbPr component cable pins provide the following input that further converts into a complete picture when they all combine.

  • Y – Green Cable – Brightness Information
  • Pb- Blue Cable – Blue color Component
  • Pr – Red Cable – Red Color Component
  • All Three Signals – Green Color Component

As I already mentioned the HD capability of the component cable here, I want to let you know that it can provide 1080 HD resolution. It can perform the progressive scan of images, smoothen the images, and have defined edges that give excellent picture quality. Despite their advantages, composite video signals are still analog and cannot compete with digital signals.

YPbPr Vs AV 02

Interference from radiofrequency and electrical signals caused due to surrounding devices can diminish the image quality. Though the signal of the component video is not as compressed as composite videos when compared to digital information, they are still compressed. This does make the digital signal the most preferred transfer mode, which is achieved using HDMI and DVI Cables.

Although there are several differences between the component and composite video signals, one thing is common for YPbPr Vs. AV, i.e., interference. As they are analog signals, they have signal distortion when encountered with radio signals or electric signals nearby. You may experience disturbance in both audio and video or any of them, depending on the interference’s strength.

 Digital Signals

Digital signals provide excellent video and audio output that is far better than analog signals. The higher resolution, better color, and the better sound improve with the cable quality. You can observe that the colors displayed are natural and vivid in high resolution. They contain only a single connector and connect to the suitable port on the device. These wires come calibrated with a resolution where higher resolution wires can allow both lower and higher resolution data, but a lower resolution cable cannot render higher resolution. Digital signals are desirable for users as they are not vulnerable to and interference or noise.


Modern devices are entirely adapted to digital signals, and soon the analog video signals might become a rare sight. Though not completely vanished, they can reduce drastically due to the impeccable quality digital signals offer. They also have several other advantages in comparison to the analog signals of both types.
