An introduction to HDMI cables

Founded by Silicon Image, Matsushita Electric Industrial (Panasonic / National / Quasar), Thomson (RCA), Hitachi, Philips, Sony and Toshiba, High Definition Multimedia Interface (or, as it is popularly called, HDMI) has succeeded in establishing a standard for video and audio connection, making it a must-have for high-definition home theater. HDMI is a digital connection that has both high resolution audio and high definition video over a single cable leads. Unlike analogue versionswhere there are several outlets in audio and video separately, HDMI can do the job with a USB connector, all while producing a high quality sound and image. HDMI is capable of handling 1080p video at 60 frames per second.

Since the digital option for the older analog models (eg, VGA, SCART, composite video, coaxial RF and S-Video), HDMI to TV and PC video formats to support more than one cable and to manage more than 8 digital audio channels. Thealso has a Consumer Electronics Control (CEC), connecting the user to control more than a couple of devices with one remote.

The advent of high definition television (HDTV) has led to an increased demand for HDMI cables. As it stands, every HDTV comes with 2 or more HDMI inputs, so that a link with gadgets such as game consoles, DVD players, Blu-ray players, DVRs.

Unlike the old cables, an HDMI video and audio feeds combined into a single cable.

SinceThere are four types of HDMI ports. Type A and type B falls below the 1.0 HDMI, HDMI Type C drops below 1.3, and D-type part of the HDMI 1.4.

Type A is supplied with the kind of bandwidth to support the capacity of digital television has a mode, ie, SDTV, EDTV and HDTV. It has 19 pins and a 13.9 mm × 4.45 mm connectors, which measures 14 mm × 4.55 mm female connector electrical installation, Type A HDMI is synchronized with a single-link DVI-D.

Type B has 29 pinsand can support twice the video bandwidth, which can be type A, and are best used for displaying high-resolution WQUXGA (3840 × 2400) images. Electrically can be synchronized with dual-link DVI-D.

Type C, as type A, has 19 pins, although it has a small connector. There is a mini connector for portable devices.

Type D is a 19-pin micro connector similar to a micro-USB connector.

The fact is that HDMI cables are an important part of the puzzle when it comes to modern electronic devices.You can not connect without it.

A brief introduction to high-definition media interface (HDMI)

HDMI stands for High Definition Media Interface. HDMI is the preferred method for connecting digital media devices (such as speakers, televisions, DVD players and stereo systems) in an integrated system. E 'common information in a digital high-definition format is used, but can also connect standard sizes - so a connection is possible between HD Ready and not HD ready devices and means that you do not need to be very new system purchase, if built with a single device HD, but HDover time.

By the way, refers HD (high definition) digital information with a resolution of 720 or higher. The resolution refers to the number of pixels per unit, for display, the device is per square inch, the more pixels per square inch greater sharpness.

To transfer information from one device to another, for example, TV and DVD player, cable is required. With an HD system, we call this HDMI cable. They are very popular because the connectionrequires only one wire for video and audio information in the past, each support requires a separate line.

It 'important to get a high quality cable, because the signal travels along the wire may lose quality in the communication of information. A well-designed cables to lose a bit 'of the original signal, while a poorly constructed cable information to the extent that images and sounds lose distort beyond recognition. For this reason, it is important to pay a small fee forMaintaining the integrity of the signal.

There are many different types of cables, is available in a variety of materials and lengths, but not all cables are equally good. Here we will consider the features that you need an HDMI cable.

Duration:
The length is the most important consideration in choosing your cable. You need to make sure you have a cable that conveniently between devices to purchase a connection is reached. It is good to purchase a cable of 1.5 m, if necessary, by a piece of a pageOne room to another. However, the cables are longer than 1.8 m additional insulation to ensure that the information is not lost, because the signal travels on the wire. When purchasing cable so if you must be the correct length, and all cables are more than 1.8 m of shielding. Note that with more insulation, the cable should be more expensive, so a little 'bigger than 1.8 m to pay for cable (6').

Material:
HDMI cables are available in a variety of materials, the most commoncopper. For daily use is made of copper and produces large fine quality and very little signal loss. For the gold from you with your HD equipment for more sophisticated efforts, like creating music, you might want to buy cable or silver, this will improve the quality of the signal a bit ', but beyond that there are hard and durable, so that the cable is not damaged can be in time to the point where copper cables.
