How many cables should be in a component video cable?
The three cables in a component video cable should all be of the same electrical length–which is to say, it should take a signal the same time to travel through each of them as it does to travel through the others.
Are component cables better than HDMI cables?
Here’s what I found: Component cables are capable of carrying a full bandwidth 1080p signal, so with all things being ideal, a component cable and a HDMI cable can bring you the same level of quality. However, things are not ideal because support for that signal is unofficial: the CEA did not approve it as part of the standard.
What is the best conductor material for a video cable?
The universal choice of conductor material in professional video cables, used in the production and broadcast industries, is copper. One will sometimes see silver touted as being superior, on the basis that silver is slightly (about 5%) more conductive than copper.
Do I need a component or HDMI cable for 1080p?

Is RCA an HD?
RCA use has declined to some degree in recent years due to the introduction of HD systems. This is because the RCA connection cannot carry a standard HD signal. However, despite this development, the use of RCA connections in electronics is still quite popular in many areas of function.Dec 9, 2019
Is HDMI better than component?
The two most desirable connectors for HD video are component and HDMI. Both work well, but of the two, HDMI is the better choice. It's a single cable for both audio and video hook-up that delivers superior picture quality, surround-sound audio, 3D support, and more, verses multiple cables using component connections.Oct 13, 2021
Can you convert HDMI to component?
Portta HDMI to RGB Converter The HDMI to Component converts HDMI video signal to Analog component/YPbPr, taking the input resolution from your device and converting it into an analog signal at the same resolution.
What makes a good video cable?
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 . 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. 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. If the claim is made that so-and-so’s component video cables exceed the performance of the best broadcast-industry cable, then find out what the basis of that claim is. The manufacturer knows what his specs are; if he won’t publish them, there’s a reason.
What is component video cable?
Component video cable, in just a few years, has gone from being a relatively uncommon and esoteric way to hook up video devices to being the near-universal analog video signal standard for home theater and high-definition television. 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 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.
What type of cable is used to connect video to TV?
For many years, the standard method of hooking analog video devices to one another has been through 75 ohm video coaxial cable. 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. 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). Not too surprisingly, when component and RGB video came into common use, the same type of cable was used to hook them up–the difference being, of course, that when there are three signals, as in a Y/Pb/Pr component video cable run, one needs three cables to run them in.
What is 75 ohm cable?
When we say that a video cable is “75 ohm” cable, this is a reference to the cable’s “characteristic impedance.” Characteristic impedance is a bit difficult to understand; although it’s expressed in ohms, like resistance, if you take a volt-ohmmeter to a video cable, you won’t find 75 ohms of resistance anywhere. 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, to over-simplify for a moment, that for every volt of signal presented, current will flow through the circuit at the rate of 1/75 ampere). When device inputs and outputs are not impedance-matched, portions of the signal can be reflected back and forth through the connection between them; in a severe case, this will manifest itself as ghosting, or “ringing,” of the image. 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.
How many cables are in a video cable?
So, whether they’re joined together in a sheath, bonded together in a ribbon configuration, or just run separately, component video cables always consist of three cables which are electrically separate. Each member of the set of three is its own, separate 75 ohm video coaxial cable, with its own center conductor and shield.
How many pins are there in a component video?
Component video is sometimes run through a VGA, or “HD15” type connector, which has fifteen pins, arranged in three rows of five; this is done most often on projectors, probably to save space, and is a source of potential confusion because the standard VGA signal format, which many projectors also accept, is not component video but RGBHV. One cannot always assume that a device with an HD15 input will accept component video; computer monitors almost never will, data projectors sometimes will, and home theater projectors almost always will. 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. The HD15 is a nasty little connector, not really well-adapted to this sort of use, and poorly sized from the point of view of video cable–but when you’ve got to use one, of course, none of that matters much.
How many nanoseconds should a cable be?
But timing, as we’ve suggested, is often a bit over-sold. The broadcast-quality benchmark standard is that timing should be within 40 nanoseconds (abbreviated “ns”) from one channel (that is, one cable in the set of three in a component video cable) to another. Using a cable having a tight impedance tolerance of +/- 1.5 ohms, or +/- 3 ohms, it’s impossible to get more than a few nanoseconds per hundred feet of timing variance from one cable to another, if those cables are cut to the same physical length. Cutting them to different lengths, of course, would do the trick–but it takes a large discrepancy in cable lengths to make up a 40 ns difference. Consider, for example, Belden 1694A. 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. 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.
What is the difference between RGB and composite video?
The RGB signal is used for color information, while the composite video signal is only used to extract the sync information. This is generally an inferior sync method, as this often causes checkerboards to appear on an image, but the image quality is still much sharper than standalone composite video.
How many signals does RGB need?
In addition to the red, green and blue color signals, RGB requires two additional signals to synchronize the video display. Several methods are used:
What is sync on composite?
sync on composite (not to be confused with composite sync), where the signal normally used for composite video is used alongside the RGB signal only for the purposes of sync.
What is composite video?
Not to be confused with Composite video. Video signal that has been split into component channels. Three cables, each with RCA plugs at both ends, are often used to carry YPbPr analog component video. Component video is an analog video signal that has been split into two or more component channels. In popular use, it refers to a type ...
What color monitors are used for arcade games?
All arcade video games, other than early vector and black-and-white games, use RGB monitors. In addition to the red, green and blue color signals, RGB requires two additional signals to synchronize the video display. Several methods are used:
What is the color of a video signal?
Further types of component analog video signals do not use separate red, green and blue components but rather a colorless component, termed luma, which provides brightness information (as in black-and-white video). This combines with one or more color-carrying components, termed chroma, that give only color information. Both the S-Video component video output (two separate signals) and the YP B P R component video output (three separate signals) seen on DVD players are examples of this method.
What does HD/VD mean?
separate sync, where the horizontal and vertical are each on their own wire (the H and V in RGBHV; also the acronym HD/VD, meaning horizontal deflection/vertical deflection, is used)
Can HDMI cable carry 1080p?
Component cables are capable of carrying a full bandwidth 1080p signal, so with all things being ideal, a component cable and a HDMI cable can bring you the same level of quality. However, things are not ideal because support for that signal is unofficial: the CEA did not approve it as part of the standard.
Does Blu Ray have HDMI?
Some Blu-ray titles have encrypted/HDCP content that is not viewable in hi-video resolution except through HDMI. So HDMI instead of component frees you from that possible incompatibility. Many Blu-ray titles offer really amazing audio via the latest audio codecs.
