Choices in Disbursing High Definition (HDMI)

The typical direction of the article could be the available technologies, the standards that need to be applied to accomplish installations and Customer care. This is a general guide and there are many other factors to consider, but ideally, it helps to show you in which careful consideration needs to be when coming up with the decision to distribute High-definition and for you to get the right HDMI method that will suit your needs totally.

HDMI Versions:

I do not want to bore with all the technical. There are many different High-definition multimedia interface versions of High-definition multimedia interface. They are: 1.A single, 1.2, One.2a, 1.3a, 1.3b, One particular.3c and now 1.4. Just remember that Nigeria is a late-comer to the hi-def party. So what really does that mean? Basically, any time HD Blu Ray along with HD DSTV were introduced in SA the High definition multimedia interface Version was A single.3b. Thus make sure all of your equipment is 1.3b, A single.3c or 1.Some. HDMI is in the opposite direction compatible with older variations of HDMI.

Version 1.4 will be the latest version and supports 3D TV.

HDMI Wires:

HDMI cables are getting to be one of the most common cables found in a household right now. As HD is a reasonably new technology inside South Africa there have been a few misunderstandings that took place with the South African Consumers. Firstly, there are several wire gauges and other internal compositions. Don't worry about the compositions. High quality copper cable will perform the trick.

The important thing to recollect is that an HDMI Cable does not expense R 1000. The particular South African consumer has been mislead into thinking that a R 1000 cable is superior to a R Eighty five cable. This is not genuine, as the important thing to keep in mind is longer HDMI cables should make use of thicker wire. I personally recommend and purchase gold platted 28 AWG HDMI cables.

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

Nearly all Blu Ray and set top box manufacturers (DSTV HD PVR) include HDMI cabling with the item and the are not suitable. These kind of cables are of a lower grade and are acceptable for connecting directly to High-definition TVs if they are really short (less than One particular meter). I have had to change many of them in the past.

A small problem is that when it comes to circulating the signals for you to remote locations connection issues do occur. While purchasing a new Blu-ray only upgrade your HDMI cable tv, but don't go overboard on what you pay for the High-definition multimedia interface Cable. Distributing HDMI signals with High-definition multimedia interface Cables to several locations, like sleeping rooms and patios, is a problem as the HDMI Connection is large and getting that though conduit is actually impossible. The second dilemma is that extending earlier a 10 meter length may cause performance concerns due to signal attenuation. That is why there are so many different technology offered to distribute for you 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 interface Splitters split the alerts in multiples associated with two. For example 1x2, 1x4, 1x8 as well as 1x16. This means that the splitter usually takes one HD feedback and will split that input signal to two, 4, 8 or 16 outputs. Homes rarely use 1x8 and 1x16 splitters. These are the most common splitters that you will find.

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

HDMI Extenders:

High-definition multimedia Extenders are the backbone of distributing to be able to multiple locations. There are many different types and amounts it is almost impossible to tell apart between them. The most common you will find are the dual CAT5e traction devices. These extenders perform perfectly, but there are several issues that attribute for the performance of these extenders. One is the installation of scalping strategies. I have been called out to many installation internet sites where the quality of the set up is the main reason regarding poor system performance, where a close next is the quality of the UTP (Kitty) cable used. There's two types of dual Kitten extenders, standard stretchers which distribute indicators to 25 metres and super stretchers up to 50 meters.

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

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

One of the most recent submitting techniques is disbursing HD over Ethernet (IP) systems, I am not likely to comment much on this technology as I personally have not used or even tested it, however thought that I would bring it up. This is going to change the distribution of HD forever as I think that all the video and audio technology is moving towards IP based systems.

High definition multimedia interface Matrix:

HDMI Matrixes are the epitome of current HDMI Engineering. The flexibility of these systems is awesome. The most common associated with HDMI matrixes are 4x4. This allows you to watch any full HD resource on any display in the system. Hence this unit manages that input is shown at any one period. Newer HDMI Matrixes get CAT6 boosted outputs and possess extenders included in 1 complete package. These matrixes tend to be more expensive while there is more processing required. But for me, it really is worth every penny spent. HDMI Matrixes are more future resistant than standard splitters because when you need to add HD sources at a afterwards stage you can with no additional costs.

This too minimises the need for extra items, such as High-definition multimedia Switches, to add the actual HD source in the distribution system.

Replacement for HDMI:

Some contractors are staying totally free of HDMI distribution methods as they may have acquired technical issues with these techniques. Thus they choose the distribution on portion video (analogue HD). Aspect video is fantastic, nevertheless the only real drawback is the cabling. Once you start disbursing to more than one remote control point it becomes a nightmare. This is because you'll want 5 cables (Several video 2 sound) at each point. It can be cheaper in some regards, but when you need to amplify the component online video or put it into a matrix it tends to be pricy.

Choices Not Presented:

Now that we know what is out there, why is the customer not offered the very best solution? These technologies are not offered to the particular South African consumer. This allows the seller/installer to get carte blanch on the technique without discussing the idea first with the buyer. This poses a problem for the Southerly African Consumer because they are not getting the right item for their requirements. This is the huge problem because not considering the potential needs and will guide, in my opinion, to poor customer service.

I have seen it so often where a strategy is thrown together and later the client needs to adjust his/her system just to handle a new TV as well as HD Source. This leads to more costs concerned. Thus the contractors love it as this signifies more sales and more call outs but this, to me, just tarnishes the industry.

An affordable warning is that there are several installers who charge by what car you drive and not your needs. So my advice is that you research and get in touch with around before accepting any quotations. Obtain a feel for what you need and you will probably save money in the future. A little shopping around into HDMI syndication is not a huge hard work. There are millions of forums and also consumer write-ups on every one of the equipment that is available. I am certain that HD Basketball can wait a week. Be patient.

HDMI Cost Factors:

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

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

Many HDMI equipment vendors import their goods through China. It is important to understand that if something goes wrong with the gear, this may in fact cost a lot more than you realise. The particular shortfall with getting this equipment is that fix services are nonexistent, that is illegal in Africa. This is why we have repair facilities at FONET.

An added problem is build quality. I've found a few Chinese makes that build excellent HDMI products yet others that do not and are garbage.

A good point to remember occurs 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 equipment and build quality is great. HDMI Equipment built in the USA, is very expensive but the build quality is great. One other factor to remember is shipping in the USA is extremely costly and this drives the device cost up.

In the event the equipment is assembled throughout China under driver's licence, the quality control is astounding.

Beware, I had an accidents with an American company a few months back. His or her service was stunning. I was looking at certainly one of their systems along with wanted to know if I can buy some extra spares for backup services here in South Africa. Your reply was "buy Two systems, if something goes wrong after that replace it with the spare". Take into account that I was sourcing equipment for one big installation. I only essential one unit. The device cost 6000 People, buying two wasn't an option for "if a thing went wrong" and second of all I would make no money on the deal if I had bought 2. Bad business sense if you ask me.

As far as I am aware, and we do have a very close eye, you will find three main companies of the video chips. These are namely, Discover Electronics (Taiwan), Maxim (U . s .) and Sony (The japanese). Try and find out what chips are being used, for service reasons, as some 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 chips are the easiest potato chips to get hold of as they have got representation in Africa. Explore chips should be imported and we privately have not found any supply of Sony chips in South Africa or even around the world.

CAT6 Cable:

That is one of the most important circumstances to know about when you are considering distributing HD to remote points. The system margin of error free performance depends on it. I simply recommend CAT6 Cable. For your extra 1 or 2 rand per meter it's worthy of every cent. There are lots of grades of UTP cables. My brand choice is Lambda and The Grand. UTP CAT6 Solid ought to range about Third 4 to Third 7 per meter.

This is where so many workers and distributors of HDMI Equipment appear short. They use CAT5e which in turn for HDMI is just not great. It works though the system margin is detrimental, picture drop outs along with pink screens. Much of your problems can be fixed with just using CAT6 cable (good quality). Installing extra CAT6 Cables is a great idea for future upgrades. It is even better to use Protected CAT6 (FTP) to avoid mains interference and if you are laying CAT6 cabling outside.

A word associated with caution, this cable tv is very expensive. Anticipate a payment anything from 15 * 35 rand per gauge, depending on greed.

The easy way distribute HD indicators:

The best way to distribute High-definition is "requirement based", offering diverse solutions for the customer's needs to ensure that most requirements are achieved and future upgrade paths are available. All systems eventually will be replaced but you may proof yourself regarding between 5-10 years. It's just better to get what you want now and avoid the fiddle later.

Short falls of High-definition multimedia:

Sometimes I do not like HDMI technology since there are a few design problems. The first one is HDCP (High-bandwidth Electronic digital Content Protection). That is there to stop documenting on external recording devices. This causes handshake concerns and can make existence difficult. I have never got issues with Blu ray players, but with the DSTV High-definition PVR I have had many. I don't think that the PVR manufacturers stick to the HDMI layout Standards. The second issue is having power on the particular HDMI. This makes it quite susceptible to lightning.

The great thing is with fibre optic wire and coax cable television the power element can't be passed through, reducing turbo issues.

Lightning Security:

Lightning protection is actually imperative to have in almost any HDMI system. There are two areas where the turbo can leak to the system is the mains (AC) and on the CAT6 Cable. The best practice for protection on the AC mains that to use surge along with lightning protection models. The entire system needs to be protected. Thus almost all components such as Tv set, DSTV decoder, HDMI splitters and stretchers must have protection.

The brands that I advocate are Clearline and APC. The one protection on CAT6 Cables is using shielded cat6 cable. LAN lightning protection rule isn't followed. The margin with regard to errors is large as there are huge speed differences between LAN and High-definition multimedia.


1. Perform some research, make some calls, talk to lots of different people, have an idea of what finances to set on what you require.

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

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

4. Always employ CAT6 cable!

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

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

7. Always make certain you are protected against lightning.
