How to decide which is better HDMI cable for your equipment

We seem to live in a world of acronyms and now HDMI is just another of them. If we correct for HDMI component we seek, in fact, looking for a cable high-definition multimedia interface. It is not like the sound exciting when you set it up so that when.

What actually is the legal language is an interface for uncompressed digital audio and video data transfer. This is a truly new invention has just started in the 21 Century. Since thisTime has grown in popularity to an astonishing pace. So much so that were installed in January 2009 as a base of 600 million HDMI devices.

HDMI Cable

However, there are many variations in their specification. The basic specifications are defined as 1.0 to 1.4. Although you can use and plug and cable for optimum performance level you need to find out what are the right ones to get for that device.

There are four types of connectors - Type AType B, Type C and Type D. They are not all the same size and another big difference is the number of pins that everyone has.

The HDMI cable has a maximum length assigned. In fact, his acting is the most important for the quality of sound and image that will give us. There are category 1 cable, standard and category 2 cables that come with high-speed cables. Here you will find cables such as HDMI 1.3, so as to reflect the different basisSpecifications for them to operate.

On each cable supports all HDMI TV or video, up to 8 channels of digital audio. HDMI is electrically compatible with Digital Visual Interface (DVI) signals so you do not need to convert the signal, there is no loss of image quality when using DVI-HDMI adapter is used.

HDMI is the gaming community was recently introduced in a big way. If you connect an Xbox, you need an HDMI cable for Xbox 360PlayStation 3, PlayStation 3 HDMI cable and a PS3, you get an HDMI cable for PS3.

Fiber optic cables are really better than copper wires?

Recently the technology has proven to be fiber optic cable is rapidly replacing copper cables. Why? Since fiber optic cable to provide faster transmission and clearer signals. Goes out to longer distances in miles that stretch, making the connection more efficiently. There are many types of fiber optic cables in the market - and not all are equal. Here is a guide.

How it works

HDMI Cable

Fiber optics works by transmitting signals via light waves. It 'aFiberglass or plastic, where the light through. At the end of each fiber optic cable is a transmitter. If the information or signals to pass through these channels, it is converted into a light-emitting diode (LED), which passes through the cable.

Optical fibers are typically used in telecommunications, but also in the network, the power used, and the transmission of television signals.

Fiber optics vs. copper wires

Copper wires are fragile and difficult to maintain. MeanwhileFiber optic cables are durable and have a higher voltage. Apart from the light guides are also cheaper.

How to buy

There are two types of fiber optic cable: single-mode fiber and multimode fiber optic cable. The single fiber optic cable contains single strands of fiber transmission in one direction at a time. And 'ideal for broadband transmission. Meanwhile, the multi-fiber cable with multiple fibers, which are ideal for the transmission of signalsmedium or short distances.

When choosing a fiber optic cable, it is important for two things: the design and cable connector. Buy a loose-tube cable type for indoor use and full-wire for outdoor use.
Singlemode cables should only Fibre Channel ports, while the multi-mode FDDI cable feed must use the doors.

Which is better - HDMI or DVI?

If you're buying a new piece of home entertainment devices, then you probably have the problem of deciding what kind of connection you should use face. Many consumers just want to once and for all the better, HDMI or DVI? Unfortunately, there is no easy way to say, a kind of connection is better than the other, it really does depend on a number of factors, including the demands of individual consumers, not to mention the other specifications of the houseShow hardware they already own. In this sense, let's look at HDMI, DVI and discuss the advantages and disadvantages of each.

HDMI and DVI are actually using the same technology for processing digital video signals. This means that each type of connection capable of exceptional image quality, against the degradation caused by interference from external noise and deliver are protected. In fact, it is also possible to connect an HDMI cable to a DVI connector, and vice versawith an HDMI cable to DVI or DVI-HDMI converter. Both cables use the same technology, should provide exactly the same image quality.

HDMI Cable

However, there are a number of differences between the two formats. For example, two HDMI cables, both digital video and audio signals, so you only need to use a cable to connect. DVI cable instead, bring only carry video, so if you use DVI, you also need an extra cable for audio controlOutput. This can lead to additional costs to buy two cables, as opposed to a need, and of course with multiple runs of cable for the connection of devices is not as clean as a single cable.

HDMI has quickly become an industry standard, and the vast majority of new entertainment devices with a HDMI port. DVI is a connection much earlier, and while it was established long before a few years has mainly been replaced by HDMI. As such, DVI is more commonly found on older hardwarealthough it is still widely used in computers. DVI is also compatible with analog and digital video signals, is ideal for use with older or used equipment.

So you better? Well, it depends on you! If you are buying a new entertainment system, then it makes sense to opt for HDMI, as it grows rapidly into a worldwide standard - almost every piece of hardware in recent years has made HDMI compatible. HDMI also means that onlya cable to keep home clean and tidy and may even be cheaper than buying more cables helps. HDMI is also great for connecting multiple devices together as two-way mode allows each device to communicate with all other units in size.

However, if you can not afford to upgrade the whole system then DVI is still a good alternative, as it works with old and new devices in the same way. In fact, if the entertainment system, then by DVI is the best optionbecause it is rare to find HDMI ports on computer hardware. No matter what type of connection you choose, is to provide exceptional image quality, so we are really all up to what combination of electronic entertainment devices are compatible with existing, if you upgrade your current system or buying a completely new system.

HDMI is an advanced and robustForm of DVI. And 'extensively developed to replace DVI and become the de facto standard for consumer electronics manufacturers. Uses HDCP (High-bandwidth Digital Content Protection) protocol, which protects the output against piracy and provides a secure connection between the source and sink. HDMI HDCP consensus helped associations of cable and satellite have HDCP required to prevent piracy. Although the latest version of HDMI is backwards compared to previous versionscompatible with earlier versions and with DVI devices.

Since the first version of HDMI in 2002, new features were added in each version. Even if all 1080pi video resolution support, they differ in their audio capabilities. Version 1.0 can decode most versions of audio contained in DVD and digital TV signals, including Dolby Digital and DTS.
