HDMI Cable, 1.5 Metres - OZ SELLER

High Definition Multimedia Interface, or HDMI, is hailed as the next generation of audiovisual cabling. Simply put, HDMI is an all-digital connector that can carry high definition video and several digital audio channels all on the one cable.

How does HDMI work?
HDMI is essentially a very fat pipe that can pump out a massive amount of digital information between two sources. HDMI cables have 5Gbps worth of bandwidth available (and up to 10Gbps with the newest version), meaning that it has more than enough capacity to carry a high definition video signal as well as up to eight channels of 24-bit high quality audio, all uncompressed. This means that there's no conversion of the signal (say, from digital to analog and then back again) or any compression that could possibly affect video or sound quality. And it does it all through one cable.

How is it different from my current analog cables?
Analog video cables, such as component, composite or S-Video, are currently the main methods used to transfer picture signals in an average home system. Component is the highest quality analog cable as it breaks down the picture signal into three different cables - one each for red, blue and green. When you've got analog cabling connecting digital sources (such as an LCD or plasma screen with a DVD), the digital video or sound signals have to be converted into analog to travel through the cable, before being re-converted back into digital at the receiving end. This could lead to some signal degradation and a resulting loss in output quality.

What are the advantages of going digital with HDMI?
HDMI can deliver high quality sound or vision without the risk of quality loss due to the conversion or compression of a video or audio signal. HDMI pictures should be smoother and sharper, with a distinct reduction in video noise. Sound should be crisp and taut, without any distortion. And of course, using the single cable HDMI can get rid of a lot of messy cables snaking around your home theatre kit.

Because of its digital nature, HDMI also works well with fixed-pixel displays such as LCD, plasma or DLP screens and projectors. A HDMI cable allows you to exactly match pixel-by pixel the native resolution of the screen with whatever source device you've got connected. HDMI systems will also automatically convert a picture into its most appropriate format, such as 16:9 or 4:3.
HDMI has some built-in smarts that allow you to control any device connected via HDMI through the one remote. Since the HDMI connection allows two-way communication between devices, it gives you basic universal remote-like functions which, for example, can tell a HDMI-linked system at a press of a button which components to turn on or off when you want to watch a DVD.

How does DVI fit into the equation? Is it better than HDMI?
You may have heard of digital video interface (DVI), which is another all-digital connector for video. DVI has been around for longer, and can be found in many more televisions and other devices than HDMI. DVI was initially developed as a connector between PCs and monitors, but eventually found its way into the home entertainment world.The HDMI standard is actually based on DVI, so picture quality on both should be similar. Where HDMI has it over DVI is its audio capabilities - DVI can only carry video signals. HDMI cables can also be made longer than DVI - HDMI can go up to 15m in length. And from an aesthetic viewpoint, HDMI connectors are less bulky than DVI ones. HDMI connects like a USB device for PCs, while DVI still has screw pins on its connector.

I've got some gear with DVI connectors. Will they work with HDMI?
Never fear - HDMI is fully backwards compatible with DVI, so you won't be making your DVI products obsolete if you buy something with an HDMI connector. For example, HDMI televisions will display video received from existing DVI-equipped products, while a HDMI DVD player will play on a DVI-equipped television. All you'll need is a HDMI/DVI adaptor. Just be aware that doing this will lose you the added functionality of HDMI, such as automatic screen format conversion and universal remote control.

What products support HDMI?

HDMI is still relatively new to the Australian market, but most new DVD players, set-top boxes and TVs feature at least one HDMI port, and they're not all high end gear. On the display side of the equation, most new screens, projectors and DVD players support the standard.
