The direction of the article could be the available technologies, the standards that need to be applied to accomplish installations and CUSTOMER SERVICE. This is a general guide and there are many other elements to consider, but hopefully, it helps to show you wherever 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 fully.

HDMI Versions:

I don't want to bore with the technical. There are many different High-definition multimedia interface versions of High-definition multimedia. They are: 1.One, 1.2, One particular.2a, 1.3a, 1.3b, One.3c and now 1.4. Just remember that South Africa is a late-comer to the high definition party. So what does that mean? Basically, when HD Blu Ray and also HD DSTV were introduced in SA the High-definition multimedia Version was 1.3b. Thus make sure your entire equipment is 1.3b, One.3c or 1.4. HDMI is in the opposite direction compatible with older variations of HDMI.

Edition 1.4 is the latest version and supports 3D TV.

HDMI Cabling:

HDMI cables are getting to be one of the most common cabling found in a household today. As HD is a pretty new technology inside South Africa there have been a number of misunderstandings that transpired with the South Photography equipment Consumers. Firstly, there are various wire gauges and other internal compositions. Don't worry about the compositions. Quality copper cable can do the trick.

The important thing to recollect is that an High definition multimedia interface Cable does not expense R 1000. Your South African client has been mislead into thinking that a 3rd r 1000 cable is better than a R Eighty-five cable. This is not correct, as the important thing to consider is longer High-definition multimedia cables should employ thicker wire. I personally recommend and purchase rare metal platted 28 AWG HDMI cords.

I have never had the one that has failed and returned to me. The funny thing is that they look identical to the Creature HDMI cables.

Virtually all Blu Ray and set leading box manufacturers (DSTV High definition PVR) include HDMI wires with the item that are not suitable. These types of cables are of a lower grade and are acceptable for connecting directly to HD TVs if they are genuinely short (less than A single meter). I have had to exchange many of them in the past.

The only issue is that when it comes to disbursing the signals to remote locations connection issues do occur. Then when purchasing a new Blu-ray simply upgrade your HDMI wire, but don't go overboard on which you pay for the High-definition multimedia Cable. Distributing HDMI signals with High definition multimedia interface Cables to numerous locations, like master bedrooms and patios, is a concern as the HDMI Connection is large and getting this though conduit is actually impossible. The second dilemma is that extending earlier a 10 meter length may cause performance troubles due to signal attenuation. That is why there are so many different systems 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 various different parts of the world. High-definition multimedia Splitters split the alerts in multiples involving two. For example 1x2, 1x4, 1x8 as well as 1x16. This means that the splitter usually takes one HD input and will split which input signal to two, 4, 8 as well as 16 outputs. Homes rarely use 1x8 and also 1x16 splitters. These are the most common splitters that you will find.

New technologies have authorized for switches to be included in the splitters. Examples are generally: 5x2, 3x4 and 3x8 splitters. Note that these types of splitters are not HDMI matrixes. They're just switch syndication amps. Meaning that it is possible to only view a single HD input one or multiple exhibits at any one moment.

HDMI Extenders:

High-definition multimedia Extenders are the spine of distributing to multiple locations. There are many different types and amounts it is almost impossible to distinguish between them. The most common you can find are the dual CAT5e stretchers. These extenders operate perfectly, but there are many issues that attribute to the performance of these extenders. One is the installation of scalping strategies. I have been called in the market to many installation internet sites where the quality of the installing is the main reason regarding poor system overall performance, where a close subsequent is the quality of the UTP (Kitten) cable used. There are two types of dual CAT extenders, standard traction devices which distribute signals to 25 feets and super extenders up to 50 yards.

The benefit of using these types of extenders is that in the future one of the existing Kitten cables (good quality) enable you to run the High-definition multimedia interface signal and the other pertaining to IPTV and Home Video Networks.

Other extender options include extending signals over one CAT cable tv (catone technology), expensive at the moment, where the HD indication is distributed over one UTP (Feline) Cable. Everyday brand-new HD extender technologies are released. Some of the new technology on offer are nutritional fibre optic and coaxial extenders. These types of HD extenders, in my view, are the technologies to make use of and watch out regarding.

One of the most recent syndication techniques is releasing HD over Ethernet (Internet protocol address) systems, I am not going to comment much on this technology as I privately have not used or even tested it, however thought that I would bring it up. This is going to change the distribution of Hi-def forever as I believe 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 Technologies. The flexibility of these programs is awesome. The most common of HDMI matrixes are Four wheel drive. This allows you to watch virtually any full HD resource on any show in the system. Thus this unit manages which usually input is shown at any one occasion. Newer HDMI Matrixes possess CAT6 boosted outputs and have extenders included in one particular complete package. These kind of matrixes tend to be more expensive nevertheless there is more processing concerned. But for me, it can be worth every penny spent. High-definition multimedia interface Matrixes are more future resistant than standard splitters while when you need to add High-definition sources at a later on stage you can without additional costs.

And also this minimises the need for further items, such as High-definition multimedia Switches, to add the particular HD source in the distribution system.

Substitute for HDMI:

Some fitters are staying clear of HDMI distribution systems as they may have got technical issues with these techniques. Thus they choose the distribution on aspect video (analogue HD). Component video is fantastic, though the only real drawback could be the cabling. Once you start distributing to more than one rural point it becomes any nightmare. This is because you'll want 5 cables (3 video 2 music) at each point. It might be cheaper in some take care, but when you need to amplify the component online video or put it in to a matrix it tends to be expensive.

Choices Not Provided:

Now that we know what is actually out there, why is the consumer not offered the most effective solution? These technology is not offered to the South African buyer. This allows the seller/installer to own carte blanch on the system without discussing that first with the customer. This poses something of a problem for the To the south African Consumer as is also not getting the right item for their requirements. This can be a huge problem as this is not considering the long term needs and will lead, in my opinion, to negative customer service.

I have seen the idea so often where a method is thrown together and later the client needs to change his/her system just to handle a new TV or perhaps HD Source. Leading to more costs concerned. Thus the contractors love it as this implies more sales and much more call outs but this, to me, just tarnishes the industry.

An affordable warning is that there are many installers who demand by what car you drive and not your preferences. So my advice is that 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 syndication is not a huge work. There are millions of forums and also consumer write-ups on all the equipment that is available. I am certain that HD Sports can wait every week. Be patient.

HDMI Value Factors:

HDMI Products varies in value dramatically. Thus it is advisable to know why. Major Factors that effect prices are: place of make, video processor chips, and build quality. Place of produce is important as this can dictate how much service is available to you.

For example, assistance turnaround times about repairs and publish purchase service.

The majority of HDMI equipment marketers import their goods from China. It is important to do not forget that if something goes wrong with the equipment, this may in fact cost a lot more than you realise. The particular shortfall with acquiring this equipment is that fix services are nonexistent, which can be illegal in South Africa. This is why we have restoration facilities at FONET.

One other problem is build quality. I've found a few Chinese producers that build fantastic HDMI products among others that do not and are garbage.

A good point to remember is when you are shopping and therefore are on a tight budget, ask where it is made. An excellent general rule is the fact that Taiwan manufacture is great. The device and build quality is excellent. HDMI Equipment internal the USA, is very costly but the build quality is nice. One other factor to take into account is shipping through the USA is extremely costly and this drives the gear cost up.

When the equipment is assembled in China under license, the quality control is fantastic.

Beware, I had an accident with an American organization a few months back. Their service was stunning. I was looking at certainly one of their systems and also wanted to know if I could buy some extra spares for backup services here in South Africa. Your reply was "buy A couple of systems, if something goes wrong and then replace it with the spare". Take into account that I was sourcing products for one big set up. I only necessary one unit. The device cost 6000 All of us, buying two wasn't an option for "if one thing went wrong" and secondly I would make no money on the deal easily had bought two. Bad business perception if you ask me.

As far as I am aware, and we do keep a close eye, you'll find three main manufacturers of the video casino chips. These are namely, Investigate Electronics (Taiwan), Maxim (U . s .) and Sony (Asia). Try and find out what potato chips are being used, for service reasons, as some are easier to get hold of than the others. These chips variety in price from 80 rand (10 United states dollar) to about 150 rand (21 years old USD). Maxim chips are the easiest chips to get hold of as they have representation in South Africa. Explore chips must be imported and we privately have not found a supply of Sony poker chips in South Africa as well as around the world.

CAT6 Cable:

This can be one of the most important items to know about when you are thinking of distributing HD to be able to remote points. The system margin of mistake free performance is dependent upon it. I only recommend CAT6 Cable. To the extra 1 or 2 rand per meter it's well worth every cent. There are many grades of UTP cords. My brand personal preference is Lambda and The Grand. UTP CAT6 Solid must range about Ur 4 to R 7 per multimeter.

This is where so many workers and distributors of HDMI Equipment arrive short. They use CAT5e which for HDMI is not great. It works though the system margin is not good, picture drop outs along with pink screens. Your main problems can be sorted out with just using CAT6 cable (good quality). Installing additional CAT6 Cables is a great idea for future upgrades. It's even better to use Protected CAT6 (FTP) to avoid mains interference and if you are laying CAT6 wires outside.

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

The easy way distribute HD signs:

The best way to distribute HD is "requirement based", offering various solutions for the buyer's needs to ensure that all requirements are fulfilled and future up grade paths are available. Just about all systems eventually will be replaced but you can easily proof yourself with regard to between 5-10 years. It is just better to get what you need now and avoid the fiddle later.

Small falls of High definition multimedia interface:

Sometimes I do not similar to HDMI technology as there are a few design concerns. The first one is HDCP (High-bandwidth Digital camera Content Protection). This is there to stop taking on external saving devices. This causes handshake problems and can make living difficult. I have never acquired issues with Blu ray participants, but with the DSTV High-definition PVR I have had many. I would not think that the PVR companies stick to the HDMI design and style Standards. The second dilemma is having power on your HDMI. This makes it quite susceptible to lightning.

The best thing is with fibre optic cable and coax cable the power element cannot be passed through, reducing turbo issues.

Lightning Defense:

Lightning protection can be imperative to have in a HDMI system. There are two areas where the turbo can leak to the system is the mains (Alternating current) and on the CAT6 Cable tv. The best practice for cover on the AC mains that to use surge and lightning protection products. The entire system needs to be protected. Thus all components such as Television set, DSTV decoder, HDMI splitters and extenders must have protection.

The particular brands that I suggest are Clearline and APC. The only real protection on CAT6 Cords is using shielded cat6 cable television. LAN lightning protection can not work. The margin pertaining to errors is large because there are huge speed variations between LAN and High definition multimedia interface.


1. Do your homework, make some calls, talk with lots of different people, experience an idea of what spending budget to set on what you might need.

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

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

4. ALWAYS use CAT6 cable!

5. There are plenty of resources at your disposal utilize them and you will be laughing.

Some. If you are unsure of installing quality, ask someone!!!

7. Always ensure that you are protected against turbo.
