The general direction of the article could be the available technologies, the factors that need to be applied to do installations and Customer support. This is a general manual and there are many other features 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 HDMI versions of HDMI. They are: 1.One, 1.2, One particular.2a, 1.3a, 1.3b, One particular.3c and now 1.Several. Just remember that Africa is a late-comer to the high definition party. So what can that mean? Basically, whenever HD Blu Ray and also HD DSTV were unveiled in SA the High-definition multimedia Version was One particular.3b. Thus make sure your equipment is 1.3b, One.3c or 1.Some. HDMI is in the opposite direction compatible with older versions of HDMI.

Edition 1.4 will be the latest version and helps 3D TV.

HDMI Cables:

HDMI cables have become one of the most common cords found in a household right now. As HD is a new technology in South Africa there have been a number of misunderstandings that transpired with the South Photography equipment Consumers. Firstly, there are several wire gauges and different internal compositions. Don't be concerned about the compositions. Top quality copper cable can do the trick.

The important thing to recollect is that an High-definition multimedia Cable does not charge R 1000. The particular South African consumer has been mislead in to thinking that a Ur 1000 cable is better than a R 80 cable. This is not genuine, as the important thing to recollect is longer High-definition multimedia cables should make use of thicker wire. I recommend and purchase rare metal platted 28 AWG HDMI cables.

I have never had the one which has failed along with returned to me. The particular funny thing is because they look identical to the Monster HDMI cables.

Almost all Blu Ray and set prime box manufacturers (DSTV High-definition PVR) include HDMI cabling with the item that are not suitable. These types of cables are of less grade and are for connecting directly to Hi-def TVs if they are actually short (less than 1 meter). I have had to switch many of them in the past.

A possible problem is that when it comes to releasing the signals to remote locations interconnection issues do occur. When purchasing a new Blu-ray simply upgrade your HDMI cable, but don't go overboard on what you pay for the HDMI Cable. Distributing High-definition multimedia interface signals with High definition multimedia interface Cables to multiple locations, like sleeping rooms and patios, is a dilemma as the HDMI Plug is large and getting it though conduit is practically impossible. The second dilemma is that extending previous a 10 meter period may cause performance troubles due to signal attenuation. For this reason there are so many different engineering offered to distribute to be able to remote points.

High definition multimedia interface Splitters:

There are many different types of High definition multimedia interface splitters and they come from many different parts of the world. HDMI Splitters split the signs in multiples associated with two. For example 1x2, 1x4, 1x8 and 1x16. This means that the splitter requires one HD feedback and will split that input signal to two, 4, 8 or even 16 outputs. Families rarely use 1x8 and 1x16 splitters. These are the most common splitters that might be.

New technologies have authorized for switches to become included in the splitters. Examples tend to be: 5x2, 3x4 and 3x8 splitters. Note that these kind of splitters are not HDMI matrixes. They may be just switch distribution amps. Meaning that you'll be able to only view 1 HD input one or multiple shows at any one moment.

HDMI Extenders:

HDMI Extenders are the central source of distributing in order to multiple locations. There are so many different types and runs it is almost impossible to tell apart between them. The most common you can find are the dual CAT5e stretchers. These extenders operate perfectly, but there are numerous issues that attribute for the performance of these traction devices. One is the installation of scalping strategies. I have been called in the market to many installation websites where the quality of the installment is the main reason with regard to poor system performance, where a close subsequent is the quality of the UTP (Feline) cable used. There are 2 types of dual Kitty extenders, standard stretchers which distribute signs to 25 metres and super stretchers up to 50 metres.

The benefit of using these types of extenders is that down the road one of the existing Kitten cables (good quality) enables you to run the High definition multimedia interface signal and the other regarding IPTV and Home Video Networks.

Other extender options include extending indicators over one CAT wire (catone technology), expensive at the moment, where the HD transmission is distributed over one UTP (Kitten) Cable. Everyday brand new HD extender technology is released. Some of the technology on offer are nutritional fibre optic and coaxial extenders. These kind of HD extenders, i think, are the technologies to use and watch out for.

One of the most recent submission techniques is disbursing HD over Ethernet (Ip address) systems, I am not going to comment much for this technology as I privately have not used or tested it, on the other hand thought that I would mention it. This is going to affect the distribution of Hi-def forever as I feel that all the video and audio technologies are moving towards Internet protocol address based systems.

High definition multimedia interface Matrix:

HDMI Matrixes are the ultimate in current HDMI Technological innovation. The flexibility of these programs is awesome. The most common associated with HDMI matrixes are Four wheel drive. This allows you to watch virtually any full HD origin on any exhibit in the system. As a result this unit manages which usually input is viewable at any one time. Newer HDMI Matrixes possess CAT6 boosted outputs and have extenders included in a single complete package. These kind of matrixes tend to be more expensive as there is more processing included. But for me, it's worth every penny spent. High definition multimedia interface Matrixes are more future proof than standard splitters because when you need to add High definition sources at a after stage you can without having additional costs.

This too minimises the need for additional items, such as HDMI Switches, to add the actual HD source to the distribution system.

Option to HDMI:

Some contractors are staying free from HDMI distribution systems as they may have had technical issues with these programs. Thus they pick the distribution on component video (analogue HD). Aspect video is fantastic, nevertheless the only real drawback may be the cabling. Once you start circulating to more than one rural point it becomes any nightmare. This is because you might want 5 cables (Three or more video 2 audio tracks) at each point. It can be cheaper in some relation, but when you need to increase the component movie or put it in to a matrix it tends to be pricy.

Choices Not Offered:

Now that we know what exactly is out there, why is the buyer not offered the very best solution? These technologies are not offered to the particular South African customer. This allows the seller/installer to possess carte blanch on the technique without discussing this first with the client. This poses a bit of a problem for the To the south African Consumer since they are not getting the right item for their requirements. This is the huge problem since this is not considering the upcoming needs and will steer, in my opinion, to negative customer service.

I have seen that so often where a product is thrown together and then the client needs to modify his/her system just to take care of a new TV or HD Source. Leading to more costs involved. Thus the contractors love it as this indicates more sales and much more call outs but this, for me, just tarnishes the industry.

A reasonable warning is that there are several installers who cost by what car a person drive and not your preferences. So my advice is which you research and get in touch with around before agreeing to any quotations. Obtain a feel for what you need and you will save money in the future. Some on-line research into HDMI submission is not a huge energy. There are millions of forums as well as consumer write-ups on all of the equipment that is available. I am sure that HD Soccer can wait a week. Be patient.

HDMI Price Factors:

HDMI Equipment varies in price tag dramatically. Thus it's important to know why. Primary Factors that affect prices are: place of produce, video processor chips, and build quality. Place of make is important as this can dictate how much solutions available to you.

For example, support turnaround times on repairs and publish purchase service.

Most HDMI equipment distributors import their goods through China. It is important to remember that if something goes wrong with the equipment, this may in fact be more expensive than you realise. The shortfall with buying this equipment is that restoration services are nonexistent, that is illegal in Nigeria. This is why we have fix facilities at FONET.

An added problem is build quality. I have found a few Chinese makes that build excellent HDMI products among others that do not and are waste.

A good point to remember is the place you are shopping and are on a tight budget, ask exactly where it is made. A good general rule is that Taiwan manufacture is great. The apparatus and build quality is very useful. HDMI Equipment internal the USA, is very expensive but the build quality is great. One other factor to take into account is shipping from the USA is extremely high-priced and this drives the equipment cost up.

If your equipment is assembled in China under license, the quality control is amazing.

Beware, I had in a situation with an American company a few months back. His or her service was stunning. I was looking at one among their systems along with wanted to know if I possibly could buy some extra extras for backup services here in South Africa. Your reply was "buy Only two systems, if something goes wrong after that replace it with the spare". Keep in mind that I was sourcing gear for one big installation. I only required one unit. The system cost 6000 US, buying two was not an option for "if a thing went wrong" and subsequently I would make no amounts on the deal if I had bought 2. Bad business perception if you ask me.

As far as I realize, and we do keep a close eye, you'll find three main producers of the video potato chips. These are namely, Investigate Electronics (Taiwan), Maxim (United states of america) and Sony (The japanese). Try and find out what potato chips are being used, for support reasons, as many are easier to get hold of as opposed to runners. These chips range in price from 80 rand (10 United states dollar) to about 150 rand (21 years of age USD). Maxim potato chips are the easiest chips to get hold of as they have representation in Africa. Explore chips should be imported and we individually have not found any supply of Sony casino chips in South Africa or perhaps around the world.

CAT6 Cable:

This can be one of the most important circumstances to know about when you are thinking about distributing HD in order to remote points. The device margin of error free performance is determined by it. I just recommend CAT6 Cable. To the extra 1 or 2 rand for each meter it's well worth every cent. There are numerous grades of UTP cables. My brand choice is Lambda and The Grand. UTP CAT6 Solid ought to range about Third 4 to 3rd r 7 per multi meter.

This is where so many fitters and distributors of HDMI Equipment arrive short. They use CAT5e which in turn for HDMI is just not great. It works but the system margin isn't good, picture drop outs along with pink screens. Most of your problems can be fixed with just using CAT6 wire (good quality). Installing extra CAT6 Cables is a great idea regarding future upgrades. It can be even better to use Guarded CAT6 (FTP) to avoid mains disturbance and if you are laying CAT6 cabling outside.

A word associated with caution, this cable television is very expensive. Anticipate paying anything from 15 -- 35 rand per multimeter, depending on greed.

The easy way distribute HD signals:

The best way to distribute High-definition is "requirement based", offering different solutions for the customer's needs to ensure that just about all requirements are satisfied and future improve paths are available. Just about all systems eventually is going to be replaced but you can easily proof yourself regarding between 5-10 years. It's just better to get what you need now and avoid the fiddle later.

Short falls of High-definition multimedia interface:

Sometimes I do not such as HDMI technology as there are a few design problems. The first one is HDCP (High-bandwidth Electronic digital Content Protection). That is there to stop recording on external recording devices. This causes handshake issues and can make lifestyle difficult. I have never experienced issues with Blu ray gamers, but with the DSTV Hi-def PVR I have had many. I would not think that the PVR manufacturers stick to the HDMI design Standards. The second problem is having power on the HDMI. This makes it extremely susceptible to lightning.

The great thing is with fibre optic wire and coax cable the power element can not be passed through, reducing lightning issues.

Lightning Protection:

Lightning protection is actually imperative to have in any HDMI system. There are 2 areas where the turbo can leak in the system is the mains (Alternating current) and on the CAT6 Cable. The best practice for defense on the AC mains this to use surge and lightning protection products. The entire system has to be protected. Thus most components such as Television set, DSTV decoder, HDMI splitters and stretchers must have protection.

The brands that I advocate are Clearline and APC. The sole protection on CAT6 Cabling is using shielded cat6 wire. LAN lightning protection does not work. The margin for errors is large because there are huge speed differences between LAN and High-definition multimedia.


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

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

3. Substantiation yourself for the future as best you can.

4. Always employ CAT6 cable!

5. There are numerous resources at your disposal make use of them and you will be laughing.

Six. If you are unsure of installation quality, ask a person!!!

7. Always ensure that you are protected against fast.
