Scott Albers. Am I the only person here smart enough to realize that green starts with a G, not a Y? Likewise, neither red nor blue starts with P. The question in question is what does YPbPr stand for, not what is it. Like Reply Report 3 5 years ago.
JL Griffin. This is actually the most incomplete bs answer ever. However despite the naming YPbPr cable can be used for both progressive and interlaced video signal but at the time of it's invention that's what there was.
Hope this helps. The red green blue on the cables is actually inaccurate to the function. 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. Green components are inferred by a combination of all three signals. Since component video is spread across three separate cables, it does not need to be as compressed as composite video, allowing support for HD resolutions as high as , as well as progressive scan images that create smoother images with more defined edges.
Component cables initially replaced composite as the de facto analog video cable, thanks to its improved picture quality and HD support.
Nearly all HDTVs made today have at least one set of component inputs. Component video is also supported by most video game consoles, DVD players, digital video recorders, cable set-top boxes and Blu-ray players.
Component Limitations Component video cables are analog, just like composite cables. And also like composite cables they have inherit limitations that are tied to the analog format. Analog cables transmit their signals via waveforms, digital cables transmit their signals the same way a computer transmits data — through binary code that is decoded by the display device into a viewable picture. Because they travel via waveform, analog signals are susceptible to interference from radio waves and other electronic signals from nearby equipment.
Analog signals also have less bandwidth than digital signals, which means increased compression that can negatively affect picture quality. As I already mentioned the HD capability of the component cable here, I want to let you know that it can provide 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. 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.
Although there are several differences between the component and composite video signals, one thing is common for YPbPr Vs.
As they are analog signals, they have signal distortion when encountered with radio signals or electric signals nearby. 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. Televisions used the RGB color model in The small picture element or pixel contains all three color signals, viz, red, green, and blue. These color signals are carried on different cables and pins.
RGB is known for its quality display. RGB found its place in photography in the s, where it began the stage of creating three separate colored filters. The RGB sensors evaluate the light intensity. Further, this helps in optimizing and refining the exposure of any image.
Many scanners use the RGB model to scan a document or photograph and transfer it to the computer. The image sensors of these scanners are usually charged coupled devices. It reads the RGB signals and then processes them with the help of its algorithm for color conversions. For many applications, RGB is the base color space.
Even with many advantages, there are a few disadvantages. Analog component signals are defined and designated by YPbPr. The only difference between the two is their characteristics of being analog and digital. Otherwise, numerically both are similar. YPbPr cables are also known as Yipper cables. YPbPr is also called component video.
