What these initials mean is that the red and blue cables carry the color information of the video signal. From bandwidth and color difference signals to data formats and cable anatomy, get ready to take a look at what makes component video, well component video. Obviously, for each type of connector on an equipment panel, there's a corresponding male connector that plugs into it. In the meantime, if you have any questions or would just prefer to place your order by phone, please call us toll-free at, Retractable Power / Data Communication Center, Cleaners, Degreasers & Encapsulating Compounds. Rather, component video is the entire technology used to deliver clear, accurate, richly colored images from their starting point in a DVD player to their final destination: your eyes. Soundbars: 2.1 vs 5.1 Which is better, differences? For that reason, any manufacturer of video cable is always working to produce cable within an acceptable range around 75 ohms. However, due to copy-protection requirements, the high-definition capabilities of component video connections phased out on January 1, 2011, via the Image Constraint Token. What this means is that the elements of the cable are cylindrical (at least, when the cable is not bent), and are laid around one another, so that the axis around which the jacket, shield, and dielectric (the insulating layer between the center conductor and shield) are constructed is the same as the axis of the center conductor. The "green" connection, rather than carrying green as such, is the Y, or "luminance," channel, and in addition to carrying a signal for the total brightness value, it carries the sync pulses. However, with this type of shared configuration, you can't plug in both a composite and component video signal source (with associated analog stereo audio) to the TV at the same time. The most common form of connector for component video cables is the RCA connector. There are a few other crimp plug designs on the market which are akin to Canare's--ADC, for example--but most manufacturers of component video cables use solder connections. Where a few years ago s-video and composite were the most common and widely usable video signal standards, component video has emerged as the leader among analog hookup methods because it is the only common consumer analog signal type which supports progressive scan and high-definition resolutions, and because it is the standard output format of DVD players. Just to dispel any possible misconceptions, we'll begin this segment of our talk by saying that there's really no such thing, per se, as a Component Video Connector. Disabled JavaScript greatly reduces the functionality of our site, so in order for you to enjoy the best browsing experience possible, we recommend that you re-enable JavaScript, or disable any possible JavaScript-blocking add-ons that you may have previously installed. This connector was, of course, named for the familiar RCA company, Radio Corporation of America, and is often referred to as a "phono" connector because its original application was to allow the audio output of a phonograph to be fed into a radio or other amplifier. In sum, the things that make an excellent component video cable are simply a matter of having a well-engineered product with tight tolerances and good design. However, as we've pointed out, there's really very little loss to resistance (resistance is just another way--the inverse way--to express conductivity) in reasonable runs of component video cable, and what really undermines the claim, in any event, is that the slightly higher conductivity of silver is usually mitigated and offset by two factors: first, the silver in a silver cable assembly is usually a microscopically thin plating over a standard copper conductor, and second, the gauge of the wire is generally small; some popular silver component video cables use a 30 AWG center conductor--resulting in resistance about seven times as high (or, if you prefer, conductivity about seven times lower) as in an 18 AWG plain copper center conductor. If the question is whether we can build a component video cable with BNC connectors on one end, the answer is yes; if the question is whether we can run component video into a BNC composite, RGBHV or Y/C connection, the answer is no (at least, not without a converter box of some sort).
Over reasonable run lengths (say, under 100 feet), these losses are not really significant so long as one is dealing with a cable having a reasonably-sized center conductor (say, 22 AWG or larger). What To Do Before You Call Tech Support, What You Need to Do Before You Buy a Blu-ray Player. Any video connection is potentially subject to electrical noise which enters from a variety of sources; these range from low-frequency hum (60-cycle noise from power circuits, transformers, fluorescent lights, etc.) Very simple. Characteristic impedance has to do with whether the cable is electrically matched to the input and output circuits of video devices, which are all designed to accept or emit signals at 75 ohm impedance (meaning, essentially, that for every volt of signal presented, current will flow through the circuit at the rate of 1/75 ampere). A manufacturer specifies how close the cable is guaranteed to be to 75 ohms in a spec called "impedance tolerance," expressed as a +/- range. The advantage of component video is it can support higher resolutions because the video signals arent jam-packed into one cable, but rather separated into three. Electricity travels down the center conductor at 82% of the speed of light (this is what's called the "velocity of propagation" of the cable), and so takes 1.24 nanoseconds to travel one foot. If you have an old device such a VCR with these connectors, you may be wondering where you can find a cable that will work for your device. Theyre also known as RCA connectors. Bear in mind, using only component videos you wont receive any audio. When a cable is badly-matched to the input and output impedances, the output device, in a manner of speaking, "sees" a load of the wrong impedance, and the input device does likewise, causing these reflections. To help address these questions, we've put together this little treatise on component video, and component video cables. Faced with the problem of composite/component video inputs consolidating on most TVs available (with the added prospect of their eventual disappearance), you might think aboutdoing some long-term planning. To increase the maximum resolution (if the console can support it), you should use component cables, the ones with green, blue, and red. The most common way to save a bit of money on cable construction here is in the braid; lower-quality coaxial cables will sometimes use an aluminum braid (significantly less conductive, and consequently less effective, than copper), with poor coverage--as low as 60%.
The "blue" channel, likewise, carries B-R, blue minus luminance, or "Pb." Component video signals contain three different types of information: scan, which tells displays exactly where video lines and frames begin and end; luminance, which specifies how bright each part of the image should be; and chrominance, which controls the image's color. The abbreviation RCA stands for Radio Corporation of America which was the first company to produce these cables. Usually, attaching the cables to the ports is very easy because both the connectors and the ports on the TV are colour-coded, so its a matter of matching the colours. You can learn how to enable JavaScript in your browser by going to http://activatejavascript.org. Then, connect the home theater receiver to your TV via its HDMI output.. In this setup, component video cables connect normally. What exactly is component video, you ask? Make sure the yellow cable is plugged in properly, otherwise, the video could be black and white. First, it's important to point out that there is no such thing as a "component video connector." So dont throw away those old media devices! Another significant factor in component video cable quality is shield effectiveness. As the television or flat screen monitor reads and compares these three factors, it can automatically infer which parts of the overall image needs to be green. This is because with component video format, display devices only require red, blue and luminance values. And remember, the HDMI converter needs to be powered by an external source because extra power is needed to convert analogue to digital. BNC - BNC connectors, which were developed by Paul Neill of Bell Labs and Amphenol's Carl Concelman, are sometimes used for component video connections in high-end consumer or professional-grade electronics. However, they are still in use today and can be found in a variety of places. What is a Good FPS for Gaming? 
We're often asked whether using an adapter will introduce too much "loss" into the line; the answer is that the adapter is there to prevent loss, both from attenuation and from poor impedance tolerance, by allowing the main run to be made in larger, lower-loss cable. Component video is referred to as a multi-scan format, which means it belongs to a class of video signals that can be transferred in a varying number of lines and at different frequency rates, whether they're set in interlaced or progressive scan mode.
If component is accepted, the signals go in to pins 1 (Pr), 2 (Y), and 3 (Pb), with the grounds going to pins 6, 7 and 8, respectively; this, fortunately, corresponds to the pinout for red, green and blue in a conventional VGA/RGBHV signal, so we can use the same adapters and cables with component that we use with those signal types. Component video can be run through any of a variety of connector types, and it's still component video. Blu-ray Disc Player Audio Connection Guide, The 6 Best Mid-Range Home Theater Receivers of 2022, Home Theater Problems? This requirement for a consistent dielectric, as it happens, is directly tied to "impedance tolerance," of which we spoke above. Another recommended feature for component video connectors is non-corrosive plating with metals like nickel or gold, which help to maintain connection quality by preventing oxidation. Due to increased copy-protection, DVD recorders are not as practical for recording TV programs as they were when they first came out, and are now very hard to find. For many years, the standard method of hooking analog video devices to one another has been through 75 ohm video coaxial cable. I'm a technology columnist and tech blogger, with a love for video games, gadgets, home entertainment and personal technology. Exotic materials, novel-looking connectors, and fancy write-ups come and go; ask for a spec sheet when you shop, and demand details like impedance tolerance, shield braid coverage, and attenuation charts. Specifically, the red cable is for the audio on the left side, and the white connector is for audio on the right side. Here again, we're partial to the Canare plugs, which use a set of spring contacts to grip the jack but which can be removed easily enough with a firm tug; we have occasionally had customers report that the plugs on some of the common consumer cable brands are so tight that, when a cable was unplugged, the plug pulled the jack right off the back panel of the device. S-Video and DVI connections are already gone, and the number of component video and composite video connections is now few. To cause a 40 ns delay by cutting 1694A cables to different lengths, one would have to make one of the cables about 32 feet longer than the others--and the resulting component video cable would still, albeit just barely, be within the broadcast quality standard. With so many technical specifications and acronyms, our goal is simple-to help you understand all there is about tech without making it difficult or daunting. A cable with tight impedance tolerance, effective shielding, adequately-sized for the run and terminated with mechanically solid connectors that make good contact with the equipment jacks and don't do too much to alter the impedance of the whole assembly will outperform anything else on the market. What do the colours mean? VGA - While 15-pin VGA connectors are most often used for RGBHV (Red Green Blue Horizontal sync Vertical sync) connections, they're also capable of transmitting component video, provided that the devices that they're connected to are configured to accept component video signal. This article contains incorrect information. Do Video Signals Need to Be Routed Through a Home Theater Receiver? I like to keep up with the ever-evolving world of gadgets, home entertainment, and personal technology. And you can help other readers too , 65 Inch TV Dimensions: What You Need to Know Before Buying. If you only plug one of these in, then youll probably only have audio from one speaker or one side of your monitor or TV or no audio at all. Long before these cables were in common use in the home, broadcast and production houses were wired with 75 ohm video cable, generally running composite video. As a matter of fact, RCA is one of the most common connector styles you're likely to find on the ends of a component video cable. 
If the manufacture of the dielectric is highly consistent, and the cables are cut to equal length, then timing variation between cables will be insignificant. The speed at which a signal travels through a cable depends on two things: the physical length of the cable, and the consistency of the dielectric material. While this setup requires multiple cables, it works the best. Save my name, email, and website in this browser for the next time I comment. With all the changes in how you access home entertainment, what lies ahead? So I recommend looking for an HDMI converter that has ports for component video and also RCA audio (red and white). No cable with a 30 AWG center conductor can be built to the same impedance tolerance as the best cable with an 18 AWG center conductor.

Best Budget Projectors: Top Picks And Reviews With full-blown HD component running at about 35 MHz (that's 1080i; 1080p/60 would be double that), the wavelength of the signal, corrected for the speed of propagation in a high-quality coaxial cable, is about 24 feet, making even a six-foot component video cable a significant fraction of the wavelength and potentially a factor in signal quality (and, in the case of 1080p/60, those distances are halved). Soundbar Size Guide: What size Soundbar for Your TV Well, one thing's for sure: it's not just the three-connector cable that's attaching your DVD player to your TV. If not fiddling with AV cables at home or in front of the computer, I can be found playing tennis or padel.
Composite connections usually handled low-resolution (also referred to as standard definition) video.

In almost all cases, TVs with a shared composite/component video connection only offer one set. A BNC jack (see photo at left) looks quite different from an RCA jack--it sticks more prominently out of the equipment panel, has a smaller pin socket (which looks not unlike a pin itself, until one realizes that the "pin" is hollow), and has two nubs on the outside of its outer contact to accept the turning bayonet ring on the male connector. But instead of the colors being sent as strictly red, green, and blue information, they're transmitted as color-difference signals, which combine the colors with luminance data and sync pulses in order to conserve bandwidth. So, what makes a high-quality component video cable? The advantages of 75 ohm video coax include excellent impedance tolerance (good for preventing signal reflection, which causes ringing and ghosting), excellent shield performance (important in a high-noise environment like a TV studio), and low loss (good when one needs to run video over long distances without significant degradation).
