The general direction of this article is available technologies, standards that apply to facilities and customer service needs to be done. This is a general guide and there are many other things to consider, but I hope it helps to show that the examination must be careful when you decide to distribute the high definition and HDMI for your system that suits your needs perfectly preserved out.
HDMI versions:
HDMI Cable
I do not want to boretechnically. There are many different versions of HDMI-HDMI. They are: 1.1, 1.2, 1.2a, 1.3a, 1.3b, 1.3c and 1.4 hours. Remember that South Africa is a latecomer to the party high definition. What does it mean? In practice, if HD Blu Ray and HD DSTV in SA was launched in version 1.3b HDMI. So sure that all devices 1.3b, 1.3c, or 1.4. HDMI is compatible with previous versions of HDMI.
Version 1.4 is the latest version and supports 3D TV.
HDMICable:
HDMI cables are one of the most common cable in a home can be found today. As HD is a relatively new technology in South Africa there have been some misunderstandings that had arisen with the South African consumer. First, there are many strands of different sizes and different internal compositions. Do not worry about the compositions. Good quality copper cable will do the trick.
The important thing to remember is that an HDMI cable costs R 1000 South AfricaMislead the consumer into believing that A is better than a wire cable 1000 was 85-R. It is not true, as the most important thing to remember is to use HDMI cables should flush more often. I personally recommend and buy gold braided 28 AWG HDMI cable.
I was one that failed and came back to me before. The funny thing is that they look identical to the Monster HDMI cable.
Almost all Blu Ray and set-top box manufacturers (DSTV HD PVR) include HDMI cables with the item andthese are not suitable. These cables are designed for a lower grade and are designed for direct connection to HDTVs, if very short (less than 1 meter) are in order. I have to replace too many of them in the past.
The only problem is that, if you check the distribution of signals from remote locations connectivity problems. So when buying a new Blu-ray HDMI cable just an update, but do not overdo it, what you pay for the HDMI cable. HDMI signal distribution to multiple HDMI cablePlaces like bedrooms and terraces, is a problem, as the HDMI connection and get great leadership is there, but it is almost impossible. The second problem is that the extension of a length of 10 meters can cause performance problems because of signal attenuation. For this reason there are so many different technologies available to distribute to remote.
HDMI Splitter:
There are many different types of HDMI splitter and from different parts of the world. HDMI splitter to divide theSignals at multiples of two. For example, 1x2, 1x4, 1x8 and 1x16. This means that the splitter takes one input and HD input signal at 2, 4, 8 or 16 outputs divided. Families rarely use 1x8 and 1x16 splitters. These chips are the most common found.
New technologies have allowed to be put on the mailing list for the switch. Examples are: 5x2, 3x4 and 3x8 splitters. Note that this matrix is not HDMI splitter. I'm just switch distribution amplifiers. This means thatYou can only have one HD input on one or more screens at any time.
HDMI Extender
HDMI Extender are the backbone of the distribution to multiple destinations. There are so many different types and ranges, it is almost impossible to distinguish between them. The most common are the two CAT5e Extender. These extenders work perfectly, but there are many issues that affect the performance attributes of these extenders. One is the installation of these systems. Ito many places where it is called the quality of the installation of the main reasons for the poor performance of the system, which has closely monitored the quality of UTP (CAT) cable is used. There are two types of dual-CAT-extender, extender standard, to distribute the signals to 25 meters and super-Extender up to 50 meters.
The advantage of using this type of charge is that in the future, one of the current CAT-cable (good quality) can be used to run the HDMI signal and the other forIPTV networks and home video.
Other options include signal extender extends over a single CAT cable (Cato technology), this expensive, where the HD signal via a UTP cable (CAT) cable will be distributed. Every day a new HD Extender technology will be released. Some of the new technologies available are fiber optic extenders. This HD Extender, in my opinion, it is technology use and maintenance.
One of the latest distribution techniques, the distribution of HDEthernet (IP)-based systems, I'm not much of this technology, as I have not personally used or tried this, but I thought I'd mention it. This will change the distribution of HD forever, like me, that all video and audio technologies for IP-based systems to get excited.
HDMI Matrix
Matrices have the maximum of the current HDMI HDMI. The flexibility of these systems is impressive. The most common are 4x4 HDMI matrix. This will allow you to watch everyFull-HD source on each screen of the system. So, this device can handle, the input is displayed at any time. More recent arrays have HDMI outputs and greater CAT6 Extender included in a complete package. These arrays are usually more expensive because it involved more processing power. But for me it is worth every penny. Matrices are future-proof HDMI as standard chips based on the needs of HD sources at a later time you can add, at no additional cost.
This also appliesminimizes the need for additional elements, such as switches HDMI, the HD source to be added in the distribution system.
Alternative to HDMI:
Some installers are free to HDMI distribution systems, which may have had technical problems with these systems. Her for the distribution of component video (analog HD) opt. Component video is fantastic, but the only real drawback is the wiring. Once you begin distribution to the most remote is a nightmare. Thisis because they are 5 cables (3 video 2 audio) must have at any point. It may be cheaper in some ways, but when I switch to component video or put it in a matrix need more expensive.
Choices are not offered:
Now that we know what's out there, is why the consumer is not the best solution? These technologies are not being offered to South African consumers. This allows the dealer / installer white paper on the system without first having consulted with the client.This is a little 'a problem for South African consumers, because they are not always the right product for their needs. This is a big problem, because it does not take into account future needs and, in my opinion, poor customer service.
I have many times when a system is thrown together and then saw the needs of the customer to change his / her system, only a new HDTV or source control. This leads to increased costs. So installers like it, because it means more sales and morecall outs but this, for me, just tarnishes the industry.
A fair warning is that there are some installers who charge by what car you drive and not your needs. So my advice is that you research and call around before accepting any quotations. Get a feel for what you need and you will save money in the future. A little research into HDMI distribution is not a huge effort. There are millions of forums and consumer write-ups on all the equipment that is available. I am sure that HD Football can wait a week. Be patient.
HDMI Price Factors:
HDMI Equipment varies in price dramatically. Thus it's important to know why. Main Factors that influence prices are: place of manufacture, video processor chips, and build quality. Place of manufacture is important as this will dictate how much service is available to you.
For example, service turnaround times on repairs and post purchase service.
Most HDMI equipment distributors import their goods from China. It is important to remember that if something goes wrong with the equipment, this may in fact cost a lot more than you realise. The shortfall with buying this equipment is that repair services are nonexistent, which is illegal in South Africa. This is why we have repair facilities at FONET.
One other problem is build quality. I have found a few Chinese manufactures that build great HDMI products and others that do not and are rubbish.
A good point to remember is when you are shopping and are on a tight budget, ask where it is made. A good general rule is that Taiwan manufacture is great. The equipment and build quality is excellent. HDMI Equipment built in the USA, is very expensive but the build quality is good. One other factor to keep in mind is shipping from the USA is extremely expensive and this drives the equipment cost up.
If the equipment is assembled in China under licence, the quality control is fantastic.
Beware, I had an incident with an American company a few months back. Their service was shocking. I was looking at one of their systems and wanted to know if I could buy some extra spares for backup service here in South Africa. The reply was "buy 2 systems, if something goes wrong then replace it with the spare". Keep in mind that I was sourcing equipment for one big installation. I only required one unit. The unit cost 6000 US, buying two was not an option for "if something went wrong" and secondly I would make no money on the deal if I had bought two. Bad business sense if you ask me.
As far as I am aware, and we do keep a close eye, there are three main manufacturers of the video chips. These are namely, Explore Electronics (Taiwan), Maxim (USA) and Sony (Japan). Try and find out what chips are being used, for service reasons, as some are easier to get hold of than others. These chips range in price from 80 rand (10 USD) to about 150 rand (21 USD). Maxim chips are the easiest chips to get hold of as they have representation in South Africa. Explore chips have to be imported and we personally have not found a supply of Sony chips in South Africa or around the world.
CAT6 Cable:
This is one of the most important items to know about when you are thinking about distributing HD to remote points. The system margin of error free performance depends on it. I only recommend CAT6 Cable. For the extra 1 or 2 rand per meter it's worth every cent. There are many grades of UTP cables. My brand preference is Lambda and Le Grand. UTP CAT6 Solid should range about R 4 to R 7 per meter.
This is where so many installers and distributors of HDMI Equipment come short. They use CAT5e which for HDMI is not great. It works but the system margin is bad, picture drop outs and pink screens. Most of your problems can be solved with just using CAT6 cable (good quality). Installing extra CAT6 Cables is a great idea for future upgrades. It is even better to use Shielded CAT6 (FTP) to avoid mains interference and if you are laying CAT6 cables outside.
A word of caution, this cable is very expensive. Expect to pay anything from 15 - 35 rand per meter, depending on greed.
Best way to distribute HD signals:
The best way to distribute HD is "requirement based", offering varied solutions for the client's needs to ensure that all requirements are met and future upgrade paths are available. All systems eventually will be replaced but you can proof yourself for between 5-10 years. It's just better to get what you want now and avoid the fiddle later.
Short falls of HDMI:
Sometimes I do not like HDMI technology as there are a few design issues. The first one is HDCP (High-bandwidth Digital Content Protection). This is there to stop recording on external recording devices. This causes handshake issues and can make life difficult. I have never had issues with Blu ray players, but with the DSTV HD PVR I have had many. I don't think that the PVR manufacturers stick to the HDMI design Standards. The second issue is having power on the HDMI. This makes it very susceptible to lightning.
The great thing is with fibre optic cable and coax cable the power element cannot be passed through, reducing lightning issues.
Lightning Protection:
Lightning protection is imperative to have in any HDMI system. There are two areas where the lightning can leak into the system is the mains (AC) and on the CAT6 Cable. The best practice for protection on the AC mains it to use surge and lightning protection units. The entire system needs to be protected. Thus all components such as TV, DSTV decoder, HDMI splitters and extenders must have protection.
The brands that I recommend are Clearline and APC. The only protection on CAT6 Cables is using shielded cat6 cable. LAN lightning protection does not work. The margin for errors is large as there are huge speed differences between LAN and HDMI.
Recommendations:
1. Do some research, make some calls, speak to lots of different people, get an idea of what budget to set on what you require.
2. I really think that paying a little extra will save you in the long run.
3. Proof yourself for the future as best you can.
4. ALWAYS use CAT6 cable!
5. There are so many resources at your disposal use them and you will be laughing.
6. If you are unsure of installation quality, ask someone!!!
7. Always ensure that you are protected against lightning.
