Choices in Distributing High Definition (HDMI)
The direction of the article will be the available technologies, the standards that need to be applied to carry out installations and CUSTOMER SERVICE. This is a general information and there are many other elements to consider, but with any luck ,, it helps to show you exactly where careful consideration needs to be when creating the decision to distribute High Definition and for you to get the right HDMI system that will suit your needs totally.
I wouldn't want to bore together with the technical. There are many different HDMI versions of HDMI. They are: 1.1, 1.2, One.2a, 1.3a, 1.3b, A single.3c and now 1.4. Just remember that Africa is a late-comer to the high definition party. So what will that mean? Basically, while HD Blu Ray as well as HD DSTV were released in SA the High-definition multimedia interface Version was A single.3b. Thus make sure all of your equipment is 1.3b, One particular.3c or 1.Several. HDMI is in reverse compatible with older variations of HDMI.
Edition 1.4 may be the latest version and helps 3D TV.
HDMI cables are getting to be one of the most common cabling found in a household these days. As HD is a new technology in South Africa there have been a few misunderstandings that took place with the South African Consumers. Firstly, there are various wire gauges and other internal compositions. Don't be concerned about the compositions. High quality copper cable will perform the trick.
The important thing to keep in mind is that an High-definition multimedia interface Cable does not expense R 1000. Your South African client has been mislead in to thinking that a Ur 1000 cable is better than a R Eighty five cable. This is not true, as the important thing to keep in mind is longer High-definition multimedia cables should use thicker wire. I personally recommend and purchase precious metal platted 28 AWG HDMI cabling.
I have never had the one which has failed as well as returned to me. The actual funny thing is they look identical to the Beast HDMI cables.
Just about all Blu Ray and set best box manufacturers (DSTV High definition PVR) include HDMI cables with the item and the are not suitable. These kinds of cables are of a reduced grade and are for connecting directly to HD TVs if they are genuinely short (less than One particular meter). I have had to replace many of them in the past.
A possible problem is that when it comes to releasing the signals in order to remote locations interconnection issues do occur. When purchasing a new Blu-ray merely upgrade your HDMI cable, but don't go overboard on which you pay for the High-definition multimedia Cable. Distributing High-definition multimedia interface signals with High-definition multimedia Cables to multiple locations, like bedrooms and patios, is a dilemma as the HDMI Connector is large and getting this though conduit is practically impossible. The second concern is that extending past a 10 meter period may cause performance issues due to signal attenuation. For this reason there are so many different technology offered to distribute to be able to remote points.
There are many different types of High-definition multimedia 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 takes one HD enter and will split in which input signal to two, 4, 8 or perhaps 16 outputs. Households rarely use 1x8 and also 1x16 splitters. These are the most common splitters that might be.
New technologies have granted for switches to become included in the splitters. Examples are: 5x2, 3x4 and 3x8 splitters. Note that these kind of splitters are not HDMI matrixes. These are just switch distribution amps. Meaning that you are able to only view one particular HD input one or multiple exhibits at any one period.
High-definition multimedia interface Extenders are the central source of distributing to be able to multiple locations. There are so many different types and varies it is almost impossible to tell apart between them. The most common you will discover are the dual CAT5e stretchers. These extenders operate perfectly, but there are several issues that attribute towards the performance of these stretchers. One is the installation of scalping strategies. I have been called out to many installation websites where the quality of the set up is the main reason regarding poor system efficiency, where a close second is the quality of the UTP (Feline) cable used. There are two types of dual Kitten extenders, standard traction devices which distribute signals to 25 metres and super extenders up to 50 metres.
The benefit of using these types of extenders is that later on one of the existing Feline cables (good quality) enables you to run the HDMI signal and the other pertaining to IPTV and Home Video Sites.
Other extender options include extending indicators 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 dietary fibre optic and coaxial extenders. These types of HD extenders, in my view, are the technologies to utilize and watch out pertaining to.
One of the most recent syndication techniques is circulating HD over Ethernet (Ip address) systems, I am not likely to comment much with this technology as I personally have not used or tested it, however i thought that I would mention it. This is going to alter the distribution of High definition forever as I think that all the video and audio technologies are moving towards Ip address based systems.
HDMI Matrixes are the ultimate in current HDMI Technology. The flexibility of these methods is awesome. The most common regarding HDMI matrixes are 4wd. This allows you to watch any full HD source on any exhibit in the system. Therefore this unit manages which in turn input is exhibited at any one moment. Newer HDMI Matrixes have got CAT6 boosted outputs and have extenders included in 1 complete package. These kind of matrixes tend to be more expensive nevertheless there is more processing included. But for me, it can be worth every penny spent. High-definition multimedia Matrixes are more future evidence than standard splitters while when you need to add High definition sources at a later on stage you can with no additional costs.
This minimises the need for further items, such as High-definition multimedia interface Switches, to add the HD source in the distribution system.
Replacement for HDMI:
Some installers are staying free from HDMI distribution methods as they may have acquired technical issues with these methods. Thus they opt for the distribution on component video (analogue HD). Portion video is fantastic, though the only real drawback will be the cabling. Once you start distributing to more than one distant point it becomes the nightmare. This is because you need to have 5 cables (Three video 2 audio tracks) at each point. It might be cheaper in some take care, but when you need to enhance the component movie or put it in to a matrix it tends to be expensive.
Choices Not Presented:
Now that we know what is actually out there, why is the customer not offered the top solution? These technologies are not offered to the particular South African buyer. This allows the seller/installer to possess carte blanch on the technique without discussing that first with the consumer. This poses something of a problem for the Southern African Consumer as they are not getting the right product for their requirements. It is a huge problem because not considering the upcoming needs and will direct, in my opinion, to poor customer service.
I have seen the idea so often where a system is thrown together and later the client needs to modify his/her system just to take care of a new TV or HD Source. This may lead to more costs concerned. Thus the contractors love it as this signifies more sales and much more call outs but this, for me, just tarnishes the industry.
A good warning is that there are a few installers who cost by what car an individual drive and not your needs. So my advice is which you research and call around before agreeing to any quotations. Obtain a feel for what you need and you'll save money in the future. Some online detective work into HDMI syndication is not a huge energy. There are millions of forums and also consumer write-ups on each of the equipment that is available. I am certain that HD Soccer can wait every week. Be patient.
HDMI Price tag Factors:
HDMI Tools varies in price dramatically. Thus it's important to know why. Principal Factors that effect prices are: place of produce, video processor chips, and create quality. Place of create is important as this can dictate how much service is available to you.
For example, assistance turnaround times in repairs and publish purchase service.
Most HDMI equipment marketers import their goods through China. It is important to do not forget that if something goes wrong with the products, this may in fact be more expensive than you realise. The actual shortfall with purchasing this equipment is that fix services are nonexistent, that's illegal in South Africa. This is why we have fix facilities at FONET.
Another problem is build quality. I have discovered a few Chinese makes that build excellent HDMI products yet others that do not and are rubbish.
A good point to remember is when you are shopping and so are on a tight budget, ask in which it is made. An excellent general rule is that Taiwan manufacture is great. The gear and build quality is very useful. HDMI Equipment integrated the USA, is very expensive but the build quality is great. One other factor to remember is shipping from the USA is extremely pricey and this drives the gear cost up.
In the event the equipment is assembled inside China under license, the quality control is fantastic.
Beware, I had an incident with an American company a few months back. Their particular service was alarming. I was looking at certainly one of their systems as well as wanted to know if I could buy some extra spares for backup assistance here in South Africa. The reply was "buy A couple of systems, if something goes wrong next replace it with the spare". Understand that I was sourcing products for one big set up. I only essential one unit. The device cost 6000 All of us, buying two had not been an option for "if one thing went wrong" and next I would make no amounts on the deal only had bought two. Bad business perception if you ask me.
As far as I realize, and we do maintain a close eye, you can find three main producers of the video casino chips. These are namely, Check out Electronics (Taiwan), Maxim (United states of america) and Sony (The japanese). Try and find out what poker chips are being used, for service reasons, as some are easier to get hold of than these. These chips variety in price from 80 rand (10 USD) to about 150 rand (Twenty one USD). Maxim casino chips are the easiest potato chips to get hold of as they have got representation in Africa. Explore chips need to be imported and we privately have not found a supply of Sony casino chips in South Africa as well as around the world.
This really is one of the most important what to know about when you are thinking of distributing HD to be able to remote points. It margin of mistake free performance depends on it. I just recommend CAT6 Cable. For the extra 1 or 2 rand for every meter it's worthy of every cent. There are numerous grades of UTP cords. My brand preference is Lambda and The Grand. UTP CAT6 Solid must range about R 4 to R 7 per multimeter.
This is where so many installers and distributors of HDMI Equipment appear short. They use CAT5e which for HDMI isn't great. It works however the system margin is detrimental, picture drop outs and also pink screens. Most of your problems can be resolved with just using CAT6 cable (good quality). Installing further CAT6 Cables is a great idea regarding future upgrades. It really is even better to use Protected CAT6 (FTP) to avoid mains interference and if you are laying CAT6 cabling outside.
A word involving caution, this cable is very expensive. Anticipate a payment anything from 15 * 35 rand per meter, depending on greed.
Best way to distribute HD signals:
The best way to distribute High definition is "requirement based", offering diverse solutions for the buyer's needs to ensure that most requirements are fulfilled and future update paths are available. Most systems eventually is going to be replaced but you can easily proof yourself with regard to between 5-10 years. It's only better to get what you need now and avoid your fiddle later.
Short falls of High-definition multimedia interface:
Sometimes I do not like 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 recording on external taking devices. This causes handshake issues and can make living difficult. I have never experienced issues with Blu ray participants, but with the DSTV Hi-def PVR I have had many. I don't think that the PVR manufacturers stick to the HDMI design Standards. The second dilemma is having power on your HDMI. This makes it very susceptible to lightning.
The great thing is with fibre optic cable tv and coax wire the power element can not be passed through, reducing turbo issues.
Lightning protection can be imperative to have in almost any HDMI system. There's 2 areas where the lightning can leak into the system is the mains (Hvac) and on the CAT6 Wire. The best practice for defense on the AC mains this to use surge as well as lightning protection products. The entire system has to be protected. Thus all components such as Television, DSTV decoder, HDMI splitters and extenders must have protection.
The brands that I advise are Clearline and APC. The only real protection on CAT6 Cabling is using shielded cat6 cable tv. LAN lightning protection can not work. The margin regarding errors is large since there are huge speed variations between LAN and High-definition multimedia.
1. Perform some research, make some calls, speak to lots of different people, receive an idea of what spending budget to set on what you're looking for.
2. I really believe that paying a little extra could save you in the long run.
3. Resistant yourself for the future the best you can.
4. ALWAYS use CAT6 cable!
5. There are many resources at your disposal use them and you will be laughing.
Half a dozen. If you are unsure of installing quality, ask someone!!!
7. Always make certain you are protected against lightning.
