The choices of distribution in high definition (HDMI)

The choices of distribution in high definition (HDMI)

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:

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 moreCalling out for me, but that's just clouds the industry.

Just a warning that some installers from the car you drive and do not charge your needs. So my advice is that you research and to call before any citations. Having an idea of ​​what you need and will save you money in the future. A little 'distribution of research HDMI is not a huge expense. There are millions of forums and write-ups on all consumer devices that are available. I'm sure that HD Footballcan wait a week. Be patient.

HDMI price factors:

HDMI equipment varies in price dramatically. So it's important to know why. Main factors that affect prices are: place of production, video-processor chip, and the quality of production. Place of production is important as this dictates the amount of service is at your disposal.

For example, the time of service delivery for repair and after-sales service.

To import most of their distribution systems from China HDMI. E 'important to remember that if something goes wrong with the unit may think this is actually much older than you. The deficit with the purchase of this device is that the repairs are not present, the illegally in South Africa. Therefore, we Phonetics repair service.

Another problem is the build quality. I found some Chinese manufacturers who are building great products HDMI, and others who do not and they are junk.

A good point is if you buy andI'm on a tight budget, ask where you are done. A good rule of thumb is that Taiwan production of large size. The features and build quality is excellent. HDMI devices built in the U.S. and is very expensive, but the build quality is good. Another factor to keep in mind is the United States from the expedition is extremely expensive and this pushes the cost of the devices.

If the device is assembled in China under license, quality control is fantastic.

Please note, I had an accident with an AmericanSociety a few months ago. The service was shocking. I was watching one of their systems and wanted to know if I could buy a couple more spare parts backup service 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 just need one. The cost for 6000 units of the United States, the purchase of two was not an option for "if something went wrong", and secondly, I would not put money in the business, if youI bought two. Bad sense economically if you ask me.

As far as I know, and we do keep an eye out, there are three main manufacturers of video chip. It is particularly in the Electronics (Taiwan), Maxim (USA) and Sony (Japan). Try to find out what chips are used for the sake of ministry, as some are easier than others to stay away. These chips in the price of 80 rand (10 USD) for 150 Rand (21 USD). Maxim chips are the easiest to keep getting chipsRepresentation in South Africa. Chips must be imported, and we have a supply of chips Sony personally in South Africa or around the world found.

CAT6 cable:

This is one of the most important elements to think about if you know the distribution of HD distant points of thinking. The margin of error-free system performance depends on it. I only recommend CAT6 cable. For the remaining 1 or 2 meters per rand worth every penny. There are many varieties of UTP cable. My brandLambda is preferred and Le Grand. UTP CAT6 solid must be about 4 to 7 for the RR meters.

Here is where are many installers and distributors of HDMI devices soon. Using CAT5e, which is not great for HDMI. It works, but the margin of the system is bad, pink screen image and dropouts. Most of your problems can be solved only with the use of CAT6 cables (good quality). The installation of additional cables CAT6 is a great idea for future updates. And 'even better, CAT6 shielded (FTP) to avoidNetwork errors, and if you have outside of CAT6 cable.

A word of caution, this cable is very expensive. Expect to pay anything edges to 15-35 meters, depending on greed.

The best way to distribute the HD signal:

The best way to distribute HD "Condition Based", offers a variety of solutions for customer needs to ensure that all requirements and future upgrade paths are available. All systems are finally replaced, but it can be shown that for her between5-10 years. It 'best to get what you want now and avoid the violin later.

HDMI is lower:

Sometimes I do not like HDMI, there are a couple of design problems. The first is HDCP (High-bandwidth Digital Content Protection). This is to stop the registration 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 many. I do not think the PVRProducers comply with HDMI standards of design. The second problem is, power over HDMI. This makes it very vulnerable to lightning.

The nice thing is with fiber optic and coaxial cable, the element of power can not be passed, creating a flash issues.

Lightning Protection:

Lightning protection is absolutely necessary to have an HDMI system. There are two areas where the flash can leak into the system, is the power (AC) and CAT6 cable. A tested method forProtection on the AC voltage and over-use units to protect against lightning. The entire system must be protected. Thus, all components such as TV, DSTV decoder, HDMI splitters and extension cords must be protected.

The brands I recommend are the clear line and APC. The only protection for CAT6 cable CAT6 shielded cable. LAN lightning protection system does not work. The margin of error is great because there are big differences in speed between LAN and HDMI.

Recommendations:

1 Clicksome research, make some calls, talk to many people an idea of ​​what budget is set based on what you need.

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

3 Try the same for the future in the best possible way.

CAT6 cable 4 EVER!

5 There are so many resources available means use it, and laughs.

6 If you are not sure of the quality of the installation, ask someone!

7 Always make sure you are protectedlightning.
