A balun can be used to extend composite RCA using ethernet, but it only works for the audio red and white cables. It is unavailable for the video yellow cable. The quality of the cable makes a big difference in the quality of the image. While there are various types of HDMI connections regular, Mini, Micro , they are all subject to the same distance limits. However, types of HDMI connected to smaller devices like cell phones and tablets are generally only available in shorter lengths since those devices are usually left close to the TV or monitor they are connected to.
The quality of the cable will determine the maximum distance. In these instances, joining two cables together with a booster is the easiest course of action. Going past that limit can still provide an HD signal, but not necessarily a 4k one. If a booster is not enough, using a balun extender will allow ethernet cable to be used to extend the HDMI signal.
Different baluns have different maximum lengths so be sure to select one that works with your specific set-up. Internet Explorer will soon be unsupported on this site.

Serving Australia since The longer the length of the headphone cable , the higher the resistance. Therefore, it is important to buy headphones with shorter cables. Don't go overboard, monoprice cables of 6ft or less will do. As for the RCA cable from the pre-amp to your receiver, it's less critical, length can be longer.
I find monoprice cables are so cheap and reasonably well-built--don't bother with cables that are cheap and cheaply built. An RCA cable can be used to connect a variety of audio and video devices, such as camcorders to TVs or stereos to speakers.
Unbalanced cables work great for connecting a guitar to an amp, for instance, but because they are not very good at suppressing noise from outside interference, unbalanced cables should have a maximum length of feet meters , especially when used in noisy environments and with signals that are low level to. Both HDMI and optical pass digital audio from one device to another. Both are better than analog the red and white cables.
Both can pass multi-channel audio, like Dolby Digital. Both cables can be had pretty cheap. However, the length you can achieve depends greatly on the cables you are using. Inexpensive optical cables lose signal quite rapidly.
But good-quality glass cables can be used for much longer runs. Balanced line level audio can travel ' quite easily. Depending on what gear you are specifically using to send the signal, you may or may not find a need to add gain with an additional device. 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.
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. Obviously, for each type of connector on an equipment panel, there's a corresponding male connector that plugs into it.
The vast majority of consumer equipment uses RCA inputs and outputs, so the vast majority of component video cables are built with RCA plugs to go into those jacks.
The RCA plug and jack, having been designed for analog audio, were not designed to match a 75 ohm characteristic impedance, and their dimensions are such that they can't be matched to 75 ohms. What one can do, however, is make the length of the mismatch as short as possible, which minimizes the impact of the mismatch.
Canare crimp RCA plugs do this by carrying the coaxial structure and dimensions of the cable forward into the plug body as far as possible; generally speaking, solder-type RCA plugs are inferior from an impedance match standpoint because the need to provide contact for soldering and allow space to screw on the connector shell do not allow the 75 ohm impedance to be carried as close to the tip as in the Canare design. 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.
Apart from impedance match, the most important characteristics of an RCA plug for use in a component video cable are its mechanical stability--that is, how well it will hold up to usage--and its facility for making good electrical contact with equipment jacks. Plating with a non-corroding metal, such as gold or nickel, helps prevent oxidation from compromising the quality of the contact, and the ideal plug should grip the jack firmly without being so tight as to damage it.
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.
That certainly makes the point that sheer mechanical grip strength, without a mechanism that enables easy removal, isn't necessarily a good thing. So, what makes a high-quality component video cable?
It really boils down to a few technical considerations; we'll go through those, and meanwhile touch on a few issues which don't really matter as much as is commonly believed.
Over normal run lengths and with cable of reasonable parameters, the amount of signal lost to resistance in the cable is not particularly significant; this is especially so because, even to the extent that resistance causes loss, the loss is linear--it affects all frequencies in the signal almost equally, and so when the display receives the signal and adjusts its amplitude usually done by reference to the strength of the sync pulses , all of the information is still present regardless of the loss of signal strength.
Over reasonable run lengths say, under 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. But there are technical deficiencies a component video cable can have, which can have dramatic impact upon signal quality, especially where runs are sufficiently long to make the impedance of the cable a significant consideration.
Here, one might ask: isn't it sufficient to make sure that the video cable is 75 ohms? After all, that's the impedance required to match all common video gear, and if one uses 75 ohm cable, there's nothing else to think about where impedance is concerned In practice, cable is seldom exactly 75 ohms. Small variations in the shape and diameter of the wire used in the center conductor, the consistency of the dielectric, the centering of the wire within the dielectric, the size and tightness of the shield around the dielectric, and the behavior of the cable when flexed, make it impossible to build cable precisely and always at 75 ohms.
For that reason, any manufacturer of video cable is always working to produce cable within an acceptable range around 75 ohms. Without a published specification for impedance tolerance, there's no way to know whether that "75 ohm" cable is 75 ohms plus or minus 1.
This is where cable size tends to come into the matter, at least indirectly. Since all of the dimensions which determine impedance have to be controlled in the manufacturing process, naturally, it's easier to control impedance tightly if the dimensions are not tiny.
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. It's simply easier to control the fineness of construction of a larger cable than it is when working with a smaller cable.
