Choices in Circulating High Definition (HDMI)


R&C Electronics CO.,LTD
The direction of the article is the available technologies, the standards that need to be applied to perform installations and Customer satisfaction. This is a general guidebook and there are many other elements to consider, but hopefully, it helps to show you wherever careful consideration needs to be when making the decision to distribute Hd and for you to receive the right HDMI method that will suit your needs fully.

HDMI Versions:

I would not want to bore together with the technical. There are many different HDMI versions of High-definition multimedia. They are: 1.1, 1.2, 1.2a, 1.3a, 1.3b, One.3c and now 1.Four. Just remember that Africa is a late-comer to the hd party. So what really does that mean? Basically, when HD Blu Ray as well as HD DSTV were unveiled in SA the High-definition multimedia Version was One.3b. Thus make sure all of your equipment is 1.3b, A single.3c or 1.4. HDMI is backwards compatible with older types of HDMI.

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

HDMI Cords:

HDMI cables have grown to be one of the most common cabling found in a household these days. As HD is a fairly new technology in South Africa there have been some misunderstandings that occurred with the South Africa Consumers. Firstly, there are many different wire gauges and different internal compositions. Don't worry about the compositions. High quality copper cable can do the trick.

The important thing to remember is that an High definition multimedia interface Cable does not price R 1000. The particular South African consumer has been mislead in to thinking that a Third 1000 cable is superior to a R Eighty five cable. This is not accurate, as the important thing to consider is longer High-definition multimedia cables should utilize thicker wire. I recommend and purchase rare metal platted 28 AWG HDMI wires.

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

Just about all Blu Ray and set best box manufacturers (DSTV High-definition PVR) include HDMI wires with the item and the are not suitable. These kinds of cables are of a reduced grade and are acceptable for connecting directly to HD TVs if they are actually short (less than One meter). I have had to switch many of them in the past.

One problem is that when it comes to releasing the signals in order to remote locations relationship issues do occur. So when purchasing a new Blu-ray simply upgrade your HDMI cable tv, but don't go overboard on which you pay for the High definition multimedia interface Cable. Distributing High-definition multimedia signals with High-definition multimedia interface Cables to a number of locations, like bed rooms and patios, is a problem as the HDMI Connector is large and getting this though conduit is almost impossible. The second dilemma is that extending prior a 10 meter length may cause performance problems due to signal attenuation. This is the reason there are so many different engineering offered to distribute to remote points.

High-definition multimedia Splitters:

There are many different types of HDMI splitters and they come from various different parts of the world. High-definition multimedia Splitters split the alerts in multiples associated with two. For example 1x2, 1x4, 1x8 and 1x16. This means that the splitter will take one HD input and will split that will input signal to two, 4, 8 or even 16 outputs. Households rarely use 1x8 along with 1x16 splitters. These are the most common splitters that you will find.

New technologies have granted for switches to become included in the splitters. Examples are generally: 5x2, 3x4 and 3x8 splitters. Note that these splitters are not HDMI matrixes. These are just switch submission amps. Meaning that you'll be able to only view one particular HD input on a single or multiple exhibits at any one time.

HDMI Extenders:

High-definition multimedia Extenders are the spine of distributing to be able to multiple locations. There are so many different types and amounts it is almost impossible to distinguish between them. The most common you can find are the dual CAT5e extenders. These extenders operate perfectly, but there are several issues that attribute to 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 regarding poor system functionality, where a close 2nd is the quality of the UTP (Feline) cable used. There's two types of dual CAT extenders, standard stretchers which distribute signals to 25 feets and super stretchers up to 50 metres.

The benefit of using these varieties of extenders is that in the foreseeable future one of the existing Feline cables (good quality) may be used to run the High definition multimedia interface signal and the other for IPTV and Home Video Sites.

Other extender possibilities include extending signs over one CAT wire (catone technology), expensive at present, where the HD sign is distributed over one UTP (Kitten) Cable. Everyday fresh HD extender technologies are released. Some of the new technology on offer are fiber optic and coaxial extenders. These kinds of HD extenders, for me, are the technologies to make use of and watch out regarding.

One of the most recent submission techniques is releasing HD over Ethernet (IP) systems, I am not gonna comment much for this technology as I personally have not used as well as tested it, however i thought that I would bring it up. This is going to affect the distribution of HD forever as I think that all the video and audio technologies are moving towards IP based systems.

High-definition multimedia interface Matrix:

HDMI Matrixes are the ultimate in current HDMI Technologies. The flexibility of these systems is awesome. The most common involving HDMI matrixes are 4wd. This allows you to watch virtually any full HD origin on any exhibit in the system. Hence this unit manages that input is exhibited at any one time. Newer HDMI Matrixes possess CAT6 boosted outputs and also have extenders included in one complete package. These types of matrixes tend to be more expensive because there is more processing involved. But for me, it is 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 additional costs.

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

Substitute for HDMI:

Some contractors are staying away from HDMI distribution techniques as they may have acquired technical issues with these programs. Thus they select the distribution on element video (analogue HD). Aspect video is fantastic, though the only real drawback will be the cabling. Once you start distributing to more than one remote control point it becomes any nightmare. This is because you must have 5 cables (3 video 2 audio tracks) at each point. It may be cheaper in some relation, but when you need to amplify the component movie or put it in to a matrix it tends to be pricy.

Choices Not Supplied:

Now that we know what is out there, why is the individual not offered the top solution? These technologies are not offered to your South African consumer. This allows the seller/installer to have carte blanch on the system without discussing this first with the buyer. This poses somewhat of a problem for the South African Consumer because they are not getting the right product or service for their requirements. It is a huge problem because this is not considering the upcoming needs and will guide, in my opinion, to poor customer service.

I have seen this so often where a method is thrown together and later the client needs to adjust his/her system just to take care of a new TV or perhaps HD Source. This leads to more costs included. Thus the contractors love it as this means more sales and more call outs but this, for me personally, just tarnishes the industry.

An affordable warning is that there are some installers who fee by what car a person drive and not your preferences. So my advice is that you just research and contact around before agreeing to any quotations. Get yourself a feel for what you need and you may save money in the future. Some on-line research into HDMI submitting is not a huge energy. There are millions of forums along with consumer write-ups on all the equipment that is available. I know that HD Sports can wait per week. Be patient.

HDMI Cost Factors:

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

For example, assistance turnaround times in repairs and article purchase service.

Most HDMI equipment suppliers import their goods coming from China. It is important to do not forget that if something goes wrong with the gear, this may in fact be of greater cost than you realise. The shortfall with purchasing this equipment is that restore services are nonexistent, which can be illegal in Africa. This is why we have fix facilities at FONET.

One other problem is build quality. I have found a few Chinese companies that build wonderful HDMI products yet others that do not and are junk.

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

If your equipment is assembled throughout China under permit, the quality control is astounding.

Beware, I had an incident with an American organization a few months back. Their service was shocking. I was looking at one of their systems and wanted to know if I can buy some extra extras for backup support here in South Africa. The actual reply was "buy Only two systems, if something goes wrong then replace it with the spare". Understand that I was sourcing equipment for one big installation. I only needed one unit. The unit cost 6000 Us all, buying two was not an option for "if some thing went wrong" and second of all I would make no amounts on the deal easily had bought 2. Bad business feeling if you ask me.

As far as I realize, and we do have a close eye, you can find three main manufacturers of the video chips. These are namely, Investigate Electronics (Taiwan), Maxim (United states) and Sony (Asia). Try and find out what potato chips are being used, for services reasons, as some are easier to get hold of than others. These chips variety in price via 80 rand (10 Dollars) to about 150 rand (21 years of age USD). Maxim potato chips are the easiest potato chips to get hold of as they have representation in South Africa. Explore chips should be imported and we professionally have not found a new supply of Sony casino chips in South Africa or even around the world.

CAT6 Cable:

This can be one of the most important items to know about when you are contemplating distributing HD in order to remote points. The machine margin of mistake free performance is determined by it. I merely recommend CAT6 Cable. For your extra 1 or 2 rand for every meter it's well worth every cent. There are lots of grades of UTP wires. My brand choice is Lambda and Ce Grand. UTP CAT6 Solid ought to range about Third 4 to Third 7 per gauge.

This is where so many installers and distributors of HDMI Equipment occur short. They use CAT5e which in turn for HDMI isn't great. It works nevertheless the system margin is bad, picture drop outs as well as pink screens. Much of your problems can be solved with just using CAT6 cable television (good quality). Installing further CAT6 Cables is a great idea regarding future upgrades. It can be even better to use Guarded CAT6 (FTP) to avoid mains interference and if you are laying CAT6 cabling outside.

A word regarding caution, this cable is very expensive. Anticipate a payment anything from 15 -- 35 rand per meter, depending on greed.

The easy way distribute HD signs:

The best way to distribute HD is "requirement based", offering varied solutions for the customer's needs to ensure that most requirements are met and future update paths are available. Most systems eventually is going to be replaced but you can proof yourself with regard to between 5-10 years. It is just better to get what you want now and avoid your fiddle later.

Brief falls of High-definition multimedia interface:

Sometimes I do not just like HDMI technology as there are a few design troubles. The first one is HDCP (High-bandwidth Electronic Content Protection). This can be there to stop recording on external saving devices. This causes handshake issues and can make lifestyle difficult. I have never acquired issues with Blu ray people, but with the DSTV HD PVR I have had many. I would not think that the PVR producers stick to the HDMI layout Standards. The second dilemma is having power on your HDMI. This makes it extremely susceptible to lightning.

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

Lightning Safety:

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

The actual brands that I advise are Clearline and APC. The one protection on CAT6 Cords is using shielded cat6 cable television. LAN lightning protection doesn't work. The margin with regard to errors is large as there are huge speed differences between LAN and High-definition multimedia.

Recommendations:

1. Do your homework, make some calls, meet with lots of different people, have an idea of what price range to set on what you're looking for.

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

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

4. Always employ CAT6 cable!

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

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

7. Always just be sure you are protected against lightning.
