Choices in Disbursing High Definition (HDMI)

R&C Electronics CO.,LTD
The general direction of the article will be the available technologies, the factors that need to be applied to accomplish installations and Customer satisfaction. This is a general information and there are many other aspects to consider, but with any luck ,, it helps to show you in which careful consideration needs to be when creating the decision to distribute Hi-def and for you to have the right HDMI method that will suit your needs completely.
HDMI Versions:

I don’t want to bore with the technical. There are many different High definition multimedia interface versions of High definition multimedia interface. They are: 1.1, 1.2, One.2a, 1.3a, 1.3b, One particular.3c and now 1.Four. Just remember that South Africa is a late-comer to the hd party. So what really does that mean? Basically, any time HD Blu Ray as well as HD DSTV were introduced in SA the High definition multimedia interface Version was A single.3b. Thus make sure all your equipment is 1.3b, A single.3c or 1.Four. HDMI is in the opposite direction compatible with older versions of HDMI.

Version 1.4 may be the latest version and sustains 3D TV.

HDMI Cords:

HDMI cables have grown to be one of the most common cords found in a household today. As HD is a fairly new technology throughout South Africa there have been a number of misunderstandings that occurred with the South Photography equipment Consumers. Firstly, there are several wire gauges and other internal compositions. Don’t worry about the compositions. Top quality copper cable is going to do the trick.

The important thing to consider is that an High-definition multimedia interface Cable does not price R 1000. The particular South African buyer has been mislead straight into thinking that a R 1000 cable is better than a R Eighty-five cable. This is not accurate, as the important thing to recollect is longer HDMI cables should use thicker wire. I recommend and purchase precious metal platted 28 AWG HDMI cables.

I have never had one that has failed as well as returned to me. Your funny thing is that they look identical to the Monster HDMI cables.

Just about all Blu Ray and set leading box manufacturers (DSTV High-definition PVR) include HDMI wires with the item and these are not suitable. These kinds of cables are of less grade and are for connecting directly to High definition TVs if they are really short (less than A single meter). I have had to replace many of them in the past.

A small problem is that when it comes to circulating the signals for you to remote locations link issues do occur. Then when purchasing a new Blu-ray merely upgrade your HDMI cable television, but don’t go overboard on the you pay for the High-definition multimedia Cable. Distributing HDMI signals with High-definition multimedia Cables to multiple locations, like master bedrooms and patios, is a dilemma as the HDMI Connector is large and getting that though conduit is practically impossible. The second dilemma is that extending previous a 10 meter duration may cause performance problems due to signal attenuation. For this reason there are so many different systems offered to distribute to remote points.

High-definition multimedia interface Splitters:

There are many different types of HDMI splitters and they come from many different parts of the world. High-definition multimedia interface Splitters split the indicators in multiples associated with two. For example 1×2, 1×4, 1×8 and 1×16. This means that the splitter requires one HD input and will split that will input signal to two, 4, 8 or 16 outputs. Homes rarely use 1×8 and also 1×16 splitters. These are the most common splitters you will likely have.

New technologies have granted for switches to become included in the splitters. Examples are: 5×2, 3×4 and 3×8 splitters. Note that these kinds of splitters are not HDMI matrixes. They are just switch submitting amps. Meaning that you’ll be able to only view a single HD input on a single or multiple exhibits at any one time.

HDMI Extenders:

High-definition multimedia interface Extenders are the anchor of distributing to be able to multiple locations. There are plenty of different types and varies it is almost impossible to differentiate between them. The most common you’ll find are the dual CAT5e traction devices. These extenders operate perfectly, but there are many issues that attribute to the performance of these extenders. One is the installation of scalping systems. I have been called to many installation sites where the quality of the installation is the main reason pertaining to poor system functionality, where a close second is the quality of the UTP (Kitten) cable used. There are two types of dual Kitten extenders, standard extenders which distribute signs to 25 feets and super extenders up to 50 metres.

The benefit of using these kinds of extenders is that in the future one of the existing Feline cables (good quality) enables you to run the HDMI signal and the other regarding IPTV and Home Video Networks.

Other extender options include extending signs over one CAT cable tv (catone technology), expensive presently, where the HD indication is distributed over one UTP (CAT) Cable. Everyday brand-new HD extender technologies are released. Some of the technologies on offer are dietary fibre optic and coaxial extenders. These kind of HD extenders, in my opinion, are the technologies to utilize and watch out with regard to.

One of the most recent submitting techniques is circulating HD over Ethernet (Internet protocol address) systems, I am not gonna comment much on this technology as I professionally have not used as well as tested it, however i thought that I would mention it. This is going to change the distribution of High definition forever as I think that all the video and audio technology is moving towards Internet protocol address based systems.

High definition multimedia interface Matrix:

HDMI Matrixes are the ultimate in current HDMI Engineering. The flexibility of these systems is awesome. The most common regarding HDMI matrixes are Four wheel drive. This allows you to watch any full HD supply on any show in the system. As a result this unit manages which in turn input is displayed at any one time. Newer HDMI Matrixes have got CAT6 boosted outputs and have extenders included in a single complete package. These kind of matrixes tend to be more expensive because there is more processing included. But for me, it’s worth every penny spent. High-definition multimedia Matrixes are more future evidence than standard splitters since when you need to add High-definition sources at a after stage you can with no additional costs.

This minimises the need for further items, such as High-definition multimedia interface Switches, to add the particular HD source to the distribution system.

Alternative to HDMI:

Some contractors are staying totally free of HDMI distribution programs as they may have experienced technical issues with these programs. Thus they select the distribution on aspect video (analogue HD). Element video is fantastic, but the only real drawback will be the cabling. Once you start disbursing to more than one rural point it becomes a new nightmare. This is because you need to have 5 cables (Several video 2 audio) at each point. It may be cheaper in some relation, but when you need to boost the component movie or put it in to a matrix it tends to be costly.

Choices Not Provided:

Now that we know what exactly is out there, why is the individual not offered the top solution? These technologies are not offered to the particular South African client. This allows the seller/installer to possess carte blanch on the system without discussing the idea first with the customer. This poses something of a problem for the To the south African Consumer because they are not getting the right product or service for their requirements. This is the huge problem since this is not considering the future needs and will lead, in my opinion, to undesirable customer service.

I have seen it so often where a strategy is thrown together and later on the client needs to modify his/her system just to take care of a new TV or perhaps HD Source. This can lead to more costs involved. Thus the fitters love it as this signifies more sales and more call outs but this, to me, just tarnishes the industry.

A reasonable warning is that there are some installers who demand by what car a person drive and not your requirements. So my advice is that you research and contact around before acknowledging any quotations. Get yourself a feel for what you need and you may save money in the future. A little shopping around into HDMI submission is not a huge energy. There are millions of forums and consumer write-ups on every one of the equipment that is available. I am certain that HD Soccer can wait a week. Be patient.

HDMI Price tag Factors:

HDMI Gear varies in value dramatically. Thus it is critical to know why. Main Factors that impact prices are: place of make, video processor chips, and build quality. Place of create is important as this will certainly dictate how much services are available to you.

For example, services turnaround times in repairs and submit purchase service.

Nearly all HDMI equipment suppliers import their goods from China. It is important to keep in mind that if something goes wrong with the tools, this may in fact be of greater cost than you realise. The particular shortfall with getting this equipment is that fix services are nonexistent, which is illegal in South Africa. This is why we have restore facilities at FONET.

An added problem is build quality. I’ve found a few Chinese manufactures that build wonderful HDMI products while others that do not and are rubbish.

A good point to remember occurs when you are shopping and so are on a tight budget, ask in which it is made. A fantastic general rule is the fact that Taiwan manufacture is great. The device and build quality is very useful. HDMI Equipment built in the USA, is very pricey but the build quality is good. One other factor to keep in mind is shipping through the USA is extremely pricey and this drives the device cost up.

If your equipment is assembled inside China under license, the quality control is fantastic.

Beware, I had in a situation with an American company a few months back. Their own service was alarming. I was looking at among their systems as well as wanted to know if I really could buy some extra extras for backup services here in South Africa. The particular reply was “buy A couple of systems, if something goes wrong and then replace it with the spare”. Keep in mind that I was sourcing equipment for one big installment. I only needed one unit. The device cost 6000 All of us, buying two was not an option for “if something went wrong” and secondly I would make nothing on the deal easily had bought a couple of. Bad business impression if you ask me.

As far as I know, and we do maintain a close eye, you’ll find three main suppliers of the video potato chips. These are namely, Investigate Electronics (Taiwan), Maxim (U . s .) and Sony (Japan). Try and find out what chips are being used, for service reasons, as many are easier to get hold of than these. These chips assortment in price from 80 rand (10 United states dollar) to about 150 rand (21 USD). Maxim casino chips are the easiest potato chips to get hold of as they have representation in Nigeria. Explore chips should be imported and we personally have not found a supply of Sony chips in South Africa or even around the world.

CAT6 Cable:

This is one of the most important things to know about when you are contemplating distributing HD in order to remote points. It margin of mistake free performance is dependent upon it. I merely recommend CAT6 Cable. For the extra 1 or 2 rand per meter it’s well worth every cent. There are several grades of UTP cords. My brand choice is Lambda and Le Grand. UTP CAT6 Solid must range about 3rd r 4 to R 7 per meter.

This is where so many installers and distributors regarding HDMI Equipment come short. They use CAT5e which for HDMI just isn’t great. It works though the system margin isn’t good, picture drop outs and pink screens. Your main problems can be solved with just using CAT6 cable (good quality). Installing additional CAT6 Cables is a great idea regarding future upgrades. It really is even better to use Shielded CAT6 (FTP) to avoid mains interference and if you are laying CAT6 cables outside.

A word of caution, this cable tv is very expensive. Count on paying anything from 15 : 35 rand per meter, depending on greed.

Easy distribute HD alerts:

The best way to distribute High-definition is “requirement based”, offering different solutions for the client’s needs to ensure that most requirements are achieved and future up grade paths are available. Almost all systems eventually will likely be replaced but you can proof yourself pertaining to between 5-10 years. It’s just better to get what you need now and avoid your fiddle later.

Brief falls of HDMI:

Sometimes I do not such as HDMI technology since there are a few design issues. The first one is HDCP (High-bandwidth Digital Content Protection). This can be there to stop taking on external taking devices. This causes handshake issues and can make life difficult. I have never acquired issues with Blu ray players, but with the DSTV HD PVR I have had many. I can’t think that the PVR manufacturers stick to the HDMI layout Standards. The second concern is having power on your HDMI. This makes it quite susceptible to lightning.

The great thing is with fibre optic cable television and coax cable the power element is not passed through, reducing super issues.

Lightning Protection:

Lightning protection will be imperative to have in almost any HDMI system. There are two areas where the super can leak to the system is the mains (Alternating current) and on the CAT6 Cable tv. The best practice for defense on the AC mains that to use surge and lightning protection units. The entire system should be protected. Thus just about all components such as Television set, DSTV decoder, HDMI splitters and traction devices must have protection.

Your brands that I recommend are Clearline and APC. The only real protection on CAT6 Cords is using shielded cat6 cable television. LAN lightning protection rule isn’t followed. The margin pertaining to errors is large as there are huge speed variances between LAN and High-definition multimedia interface.


1. Perform some research, make some calls, speak to lots of different people, experience an idea of what price range to set on what you require.

2. I really believe paying a little extra can save you in the long run.

3. Proof yourself for the future as well you can.

4. Only use CAT6 cable!

5. There are so many resources at your disposal utilize them and you will be laughing.

Half a dozen. If you are unsure of installment quality, ask an individual!!!

7. Always ensure that you are protected against turbo.
