It is the chrominance part of the video signal that has been divided into three different parts and each of them, relating the luminance and sync data, transmits colors marked on them. So, the red plug transmits red color, the blue plug transmits blue color, and the green plug is combining the luminance data and sync pulses. This is because televisions or any other players only need red, blue, and luminance values and can deduce the green parts of the picture by that information automatically.
Due to this separation of the chrominance portion, the component video gets to produce such good quality picture. As the video signals are distributed between their different cables , component video is clearer, and component cables can produce such refined pictures. Keep in mind that component cables only transmit standard and HD image resolutions; it does not transmit audio signals. For audio signals , you have to use a different optical or coaxial audio cable.
Composite cables are sometimes regarded as the last resort. It is one of the very first inventions which was able to carry a video signal from one device and project it on another. It was mainly used in the older versions of television sets, which do not support HDMI cables. It is that single-headed yellow-colored plug that comes with your device. The single RCA jack does not need to be put in any particular way; you can insert either end of the cable into your television set.
However, some have AV out marked on one end of the cable. That is the plug you should insert in your television set in that case. The composite device sends composite video signals from an input device, like a DVD player or a video camera, into a device that can display the output like a television or AV set. As mentioned earlier, composite cables transmit analog composite video signals.
This format mainly transmits standard-definition videos and travels in a single channel. Hence, it is a one-headed plug. Composite videos are sometimes referred to as CVBS , which is abbreviated to the composite video baseband signal. This signal takes care of the color, video, blanking, and the sync pulses of the image. More commonly, however, it is called the SD video as is transmits standard-definition signals only. The reason why composite video quality is average is that the signal sent through the composite cables are very compressed.
It is too much information and data for one cable to pass on. 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. Although less noticeable with component than composite, signals transmitted via component cable will not be as clear as signals transmitted digitally via cables like HDMI and DVI.
Multicom stocks the highest quality HDMI 2. While regular television signals, VHS tapes and laserdiscs all encode visual data using lesser quality composite video, DVDs use component video for encoding visual data. A DVD player with component video outputs, connected to a television with comparable inputs, will provide a picture far superior than one using composite video connections.
Component video is also a step up from S-Video in that it is a multi-scan technology, which means it can deliver the video stream in differing modes to accommodate various frame rates for progressive-scan or interlaced televisions. Component video cables are available in different configurations.
All three cables might be encased in a single sheath with triple tails at each end, or the cables might be bonded or ribboned together. Three single RCA or coaxial cables can also be used, but should be the same length and type.
Increased cable quality, tips and shielding add to the cost, as will the length of the cables. I thought it was time to bring it up again. The photo you see above is a component video cable.
Seems simple enough. This photo is a composite video cable. Component cables are designed for HDTV. This connection is video-only… you would need more cables to carry the audio. Composite cables are designed for older, standard definition systems.
