Component Video Cable Buying Guide

Component video cable is becoming a more popular way to connect high definition televisions to home theatre surround sound systems, much more so than it was in the past. Whereas composite and s-video signals were often the standard way to connect these devices, the component video type of analogue signal is now becoming the new standard for many people. Component video cable can be purchased at home improvement stores, electronic stores, and on eBay.

Understanding what component video and component video cable is used for is one of the first steps that is necessary in knowing how to choose the proper ones. Details such as understanding video cable construction along with being able to distinguish between the various types that are widely available ae helpful to many people. Understanding all of these things is what allows people to be able to choose the right component video cable that is best suited for their needs.

Component Video Cable Overview

Many people may not have heard of component video cable before, so it is essential to understand what it is before they can realise the benefits of using it in their homes. It is also equally important for people how it is used before they go out and buy it for their electronics. Being armed with as much knowledge beforehand can help alleviate much of the confusion that can often surround component video cable.

What Exactly Is Component Video?

In order to fully understand component video, it is necessary to understand first how the eyes work. Because the eye structure contains many cones and rods on the receptors, it affects how colours are viewed. Different rods and cones pick up RGB colours (red, blue, and green); therefore, it is important for colours to be captured in the proper format in order to be displayed to appear natural for us.

As analogue video signals are transmitted from one electronic device to another, bits of scan information are sent to the receiving device that tells it how bright certain images need to be as well as where frames and video lines begin and end. It also transmits scan information regarding colour requirements as well as other pertinent information that is required to receive accurate images. There are various ways that the format of this information is transmitted between electronic devices, and that depends upon the type of equipment for transmittal is used. S-video, RGB video, composite, and component video all use different formats for transmitting the information.

When component video is used, the format technology breaks down and separates various colour elements from each other and sends them in a way that allows for optimum picture quality. Because component video uses a multi-scan type of formatting, it does not have line and frame limitations like other types of video formats, such as s-video or composite video. This is what creates the need for component video when using devices that require HD. If a normal RGB signal were to be transmitted, it would require too much bandwidth, making it very costly to use. Component video resolves this issue in a more cost-effective format.

Component Video Cable

Component video cables are comprised of three cables that require individual electrical power. Component video cables come in a variety of forms, but they are still each a separate 75 ohm coaxial video cable with individual shields and conductors. They can come in forms that bind them together like a ribbon. They can be covered in a sheath or each can be their own individual parts. Regardless of how they appear, these cables share the same physical axis. These cables are joined to an electronic device with video cable connectors, the most common connectors that are used are BNC or RCA connectors; however, only one type of connector should be used and never intermixed with a different type in order to ensure proper reception.

Component Video Cable Selection

Being able to choose a high quality component video cable is important in order to get optimum use out of electronic devices. There are a few things that do matter in component video cable selection as well as some things that do not matter. Realising these factors can make choosing the right products easier and also less expensive as well.

Cable Length

One of the popular misconceptions about component video cable is that the longer it is the better it is. The fact is that the opposite is actually true. Having a component video cable that is too long can actually hinder the signal transmitted between electronic devices. Cables that are too long for the job often get bound together or hidden away and are susceptible to being damaged. There are many factors that are taken into account when it comes to having the appropriate component video cable length.

Of course the size of the cable depends largely upon the components being joined. For optimum performance it is suggested not to have a cable that is longer than the maximum required by the device being joined to it. It is not always easy to know how long that should be. The strength of the signal output from the electronic device as well as the quality of the cable used in the connection process makes a vital difference in the results that are achieved. Listed below are suggested cable lengths for various electronic devices that are commonly found in a home or business.

Electronic Devices with Standard Signals

For the purposes of this guide, the electronic devices that are being referred to are such things as a VCR or a DVD player that only requires a standard definition video signal connection. If a high quality component video cable is used, it is possible to use one that is up to 30 metres in length or even slightly longer. For electronic devices that have high definition features, it is recommended not to go much beyond five metres in length.

Component Video Extenders

Component video extenders are a common device that people use to extend the video signal to greater lengths with capabilities that include the extension being over 100 metres. Care must be used with incorporating this feature so that the signal strength is not degraded to the point where the quality suffers. Using component video extenders is ideal when a separate audio connection is being made.

Component Video Extenders with Audio

It is recommended when using component video extenders with audio features that the maximum cable length does not exceed much more than 100 metres or else the user runs the risk of the signal quality also being degraded. These extenders are often popular choices because they allow the received to be attached to a high definition television, and Ethernet cables can also be incorporated to extend the signal even further. Using this type of extension is practical when an HD receiver cannot be placed within close proximity to the high definition television unit.

Wireless Component Video Extender with Audio

Wireless component video extenders with audio feature capability are great items to have for people who do not want to have a lot of lengthy wires lying around. This type of extender is ideal for people who are unable to obtain a strong signal due to physical obstructions or when HD receivers cannot be close by. This type of device is able to transmit wireless signals to the electronic device from up to 20 metres away, and the unit can easily be stored in a cabinet or even another room or basement so that it is out of sight if so desired.

How to Buy Component Video Cable on eBay

Component video cable is easy to purchase on eBay. When a search is entered from the eBay homepage, numerous results are displayed in seconds. It is easy to make a search more specific to filter out certain items that are not wanted by also taking advantage of the advance search option feature. Searches can also be performed at the top of any eBay page for added convenience.
