The Directorate-General of this article is the technology available, the rules applied systems and customer service needs to be done. This is a general guide and there are many other things to consider, but hopefully it helps to show where careful consideration must be distributed in deciding to high definition and for the proper HDMI system that meets your needs completely.
HDMI versions:
Hdmi
I do not want to boretechnician. There are many different versions of HDMI. These are: 1.1, 1.2, 1.2a, 1.3a, 1.3b, 1.3c and now 1.4. Remember that South Africa is a latecomer to the party high definition. So what does that mean? In the end, HD Blu-ray and HD DSTV have been launched in SA HDMI version 1.3b. To ensure that all equipment is 1.3b, 1.3c, or 1.4. HDMI is compatible with earlier versions of HDMI.
Version 1.4 is the latest version and support for 3D-TV.
HDMICable:
HDMI cables are going through one of the most common cable in a home today. As HD is a relatively new technology in South Africa, there have been some misunderstandings that occurred with the South African consumer. First, there are many cables of different sizes and different internal compositions. Do not worry about the compositions. Good quality copper cable will do.
The important thing to remember is that an HDMI cable is not cost-R 1000 The South Africanentice consumers to better R 1000 R 85 cable as a cable has been misled. This is not true, because the important thing to remember more than the HDMI cable wire should be used more often. I personally recommend buying gold and 28 AWG HDMI cable.
I've never seen one that failed and was returned to me. The funny thing is that they look identical to the Monster HDMI cable.
Almost all Blu-ray manufacturers and set-top box (DSTV HD PVR) are HDMI cable for the item andthese are not suitable. These lines are from a lower grade and are suitable for direct connection to HDTVs, if very short (less than 1 m). I had a lot of them to be replaced in the past.
The only problem is that when it comes to distributing signals to remote locations will have connection problems. So when purchasing a new Blu-ray only upgrade your HDMI cable, but do not overdo it, what you pay for the HDMI cable. Distribute HDMI signals via HDMI cable to moreLocations such as room and terraces, is a question of how the HDMI connection is great and they do, but the management is almost impossible. The second problem is that it spans a length of 10 meters can cause performance problems because of signal attenuation. For this reason there are so many different technologies available, to be distributed to remote points.
HDMI Splitter:
There are many different types of HDMI splitter and from different parts of the world. HDMI Splitter to split theSignals in multiples of two. For example, 1x2, 1x4, 1x8 and 1x16. This means that the splitter takes one input and HD input signal is divided into 2 outputs, 4, 8 or 16. Families rarely use 1x8 and 1x16 splitter. These chips are the most common find.
New technologies have included for the switches in the distribution to be. Examples are: 5x2, 3x4 and 3x8 splitter. Note that this is not HDMI splitter arrays. I'm just switch distribution amplifiers. This means thatYou can only input one or more HD displays at any time.
HDMI Extender
HDMI Extender are the backbone of the distribution to multiple locations. There are so many different types and ranges, it is almost impossible to distinguish between them. The most common, see the dual Cat5e extenders. These positions work perfectly, but there are many questions that the performance of these extension attributes. One is the installation of these systems. Icalled out to many places where the quality of the installation is the main reason for the poor performance of the system, where a second place is the quality of UTP (CAT) cable. There are two types of dual CAT Extender, Extender Standard, the signals at 25 meters and super-Extender to distribute up to 50 meters.
The advantage of using this type of charges that, in future, one of the current CAT-cable (good quality), the HDMI signal can be used and the other is forIPTV and video networks.
Other options include signs extension through enlargement of a CAT (Cato technology), this expensive, where the HD signal via a UTP cable (CAT) is distributed via cable. Each new day the HD Extender is released. Some of the new technologies on offer are glass fiber and coaxial positions. This HD Extender, in my opinion, the technologies to use and watch.
One of the latest distribution techniques, the distribution of HDEthernet (IP) system, I do not have many comments on this technology, as I have not personally used or tried, but I thought I'd mention it. This will change the distribution of HD since I believe that all video and audio technologies, move to IP-based systems.
HDMI Matrix:
HDMI switcher is the latest latest HDMI technology. The flexibility of these systems is impressive. The most common matrix 4x4 HDMI. This allows you to look at allFull-HD source on each screen in the system. Be managed in this unit, which input is displayed at any time. Recent matrices HDMI Extender CAT6 and amplified in a complete package included. These matrices are usually more expensive because there is more processing involved. But for me it's worth every penny. HDMI switcher chips are more future-proof standard, as you need them for HD sources at a later time, you can add extra cost.
This is alsominimizes the need for additional elements, such as add, for example, switches HDMI, the HD source to the distribution system.
As an alternative to HDMI:
Some installers are free to HDMI distribution systems that may have had technical problems with these systems. And for distributing component video (analog HD). Component video is fantastic, but the only real drawback is the wiring. Once you start more than one point at a distance, will distribute a nightmare. Thisis because a 5 cables (3 video 2 audio) must have at each point. It may be cheaper in some respects, but if you need to strengthen the component video or put it in a matrix, tends to pricy.
The choices are not offered:
Now that we know what's out there, is because consumers would not have offered the best solution? These technologies are not offered to the South African consumer. This allows the seller / installer carte blanch to the system without first discussing both with the client.This is certainly a problem for the protection of consumers in South Africa where they are not always the right product for their needs. This is a big problem, because this is not taking into account the future needs and will, in my opinion, to poor customer service.
I have many times when a system is lumped together and since then the needs of customers and its system, just a new TV or HD source to manage change. This leads to higher costs. Sun installers, love, because it means more sales and moreCall out, but that is my only tarnishes the industry.
Just a warning that some installers from what car you drive for free and do not meet your needs. So my advice is that you can try and call before any citations. Having an idea of what you need and you will save money in the future. A little 'Distribution Research HDMI is not a massive effort. There are millions of forums and responsibilities of consumers on all available devices. I'm sure that HD-footballcan wait a week. Be patient.
HDMI price factors:
HDMI devices vary in price dramatically. It 'important to know why. The main factors that affect prices are: place of production, the video processing chips and build quality. Place of manufacture is important as this to dictate the amount of service is at your disposal.
For example, the turnaround time for repairs and service support after the sale.
Most HDMI machinery dealers import their products from China. It isimportant to remember that if something goes wrong with the device, this might actually cost a lot of money more than you think. The deficit with the purchase of this equipment is that repairs are not present, which is illegal in South Africa. Therefore, we have repair facilities phonetics.
Another problem is the build quality. I found some Chinese manufacturers, who build great products which are not HDMI and other garbage.
A good point is if you buy andI'm on a tight budget, ask where it is produced. A good rule of thumb is that Taiwan manufacture of large size. The quality of material and construction is excellent. HDMI devices built in the U.S. is very expensive, but the workmanship is good. Another factor that is sane in the United States, to keep the shipping is very expensive and this drives the cost of handsets.
When installed in China under license, quality control is fantastic.
Be careful, I had an accident with an AmericanCompany a few months ago. The service was shocking. Now I was watching one of their systems and wanted to know if I could use some spare parts to service additional backup here in South Africa. The answer was "buy two systems, if something goes wrong then replace it with the spare." Remember that I am sourcing equipment for a large installation. I have only one unit is needed. The unit cost U.S. 6000, the purchase of two was not an option for "if something goes wrong, and secondly I would not make money on the deal ifI bought two. Bad economic sense if you ask me.
As far as I know, I did, and we in the eye, there are three main manufacturers of video chips. It is in fact discover Electronics (Taiwan), Maxim (USA) and Sony (Japan). Try to find out what chips are used for domestic reasons, as some are easier to grasp than others. These chips range in price of 80 rand (10 USD) for 150 Rand (21 USD). Maxim chips are the easiest chip to the public as they graspRepresentation in South Africa. Explore chip must be imported, and we do not have a personal supply of Sony chips in South Africa and found throughout the world.
CAT6 cable:
This is one of the most important terms to know when you think about the distribution of HD on remote points. The margin of error-free system performance depends on it. I only recommend CAT6 cable. To counter the additional 1 or 2 per board, it is worth every penny. There are many types of UTP cable. The brand of mypreferably lambda and Le Grand. CAT6 UTP solid must be about 4 to 7 for RR meters.
This is where many installers and distributors of HDMI devices are short. Use CAT5e, which is not great for HDMI. It works, but the margin of the system is bad, glitch and pink screens. Most of your problems can be solved only by CAT6 cable (good quality). Installation of CAT6 cables extra is a great idea for future updates. And 'even better shielded Cat6 (FTP) to avoidnetwork failures and if outside of CAT6 cable.
A word of caution is that the cable is very expensive. Expect to pay anything to the Rand 15-35 meters, depending on greed.
The best way to distribute the high definition signal:
The best way to distribute HD is the "basic need", offers a variety of solutions for the needs of clients to ensure that all requirements are met and future upgrade paths available. All systems are finally replaced, but you can look for evidence of5-10 years. It 's really what you want now and to prevent the violin later.
Falls short HDMI:
Sometimes I do not like the HDMI, since there are a couple of design problems. The first is HDCP (High-bandwidth Digital Content Protection). What is there to stop the recording of external recording devices. This causes problems handshake and can make life difficult. I've never had problems with Blu-ray, but with the DSTV HD PVR, I have had many. I do not think that the PVRManufacturer Stick to the HDMI standard. The second problem is with the power over HDMI. This makes it very vulnerable to lightning.
The nice thing is with fiber optics and coaxial cable, the element of power can not be passed through, which makes a flash.
Grounding:
Lightning protection is absolutely necessary to have any HDMI system. There are two areas where the lightning can leak into the system, the mains (AC) and CAT6 cable. The best practices forProtection on the power cord to use it surge and lightning protection units. The entire system must be protected. Thus, all components such as TV, DSTV decoder, HDMI splitters and extenders must have protection.
The brands I recommend are clear and APC Line. The only protection on CAT6 cable is shielded with CAT6 cable. lightning protection system does not work LAN. The margin of error is large, as there are big differences in speed between LAN and HDMI.
Recommendations:
1. Yousome of the research are leading to some calls, talk to many different people to get an idea of what to budget, what you need.
2. I really think that paying a little extra, you will save in the long run.
3. The same test for the future as best as possible.
4. ALWAYS CAT6 cables!
5. There are so many resources available means use it, and you ride.
6. If you are unsure about installation, quality, ask someone!
7. Make sure you are always protectedLightning Strike.
