HDMI Cables

What's the Difference and What Does it Do For Me?

What is HDMI?

HDMI stands for high definition multimedia interface. It is a cable that makes your A/V hook-up as simple as possible. It transfers audio, video and control commands over a single cable giving you a high definition connection. HDMI connects it all from TV screens to cable and satellite boxes, game consoles, PCs, audio/video receivers, DVD players, projectors, monitors and camcorders. HDMI cables pack the flexibility to work with future capabilities and remain backwards compatibe with previous HDMI versions and DVI as well. Each new version of HDMI seeks to bring clearer pictures, sharper images, brighter colors, faster refresh rates and the highest audio performance possible.

How Did HDMI Get Its Start?

Innovative manufacturers in the consumer electronics industry founded HDMI in 2002. They include Hitachi Ltd.; Panasonic Corp.; Philips Consumer Electronics; Silicon Image Inc.; Sony Corp.; Thomson Inc. and Toshiba Corp. HDMI 1.0 is the original standard, and since then there have been five updates to the standard, bringing it to the current HDMI 1.3 Category 2 specification.

HDMI Evolves

Each version of HDMI has built on the previous one using the same type of cable, but adding bandwidth and new abilities.

* HDMI 1.0 was created to be compatible with DVI and support up to 3.96 Gbps (giga-bits per second) of video and 8-channel audio.

* HDMI 1.1 added support for DVD audio.

* HDMI 1.2 added support for Super Audio CDs and the availability of a connector for PC sources.

* HDMI 1.3 increased bandwidth to 10.2 Gbps, a huge increase over HDMI 1.0 and an even more dramatic increase over .81 Gbps throughput rate required for standard DVDs.

* HDMI 1.3 Category 1 and Category 2 specifications. The Category 2 specification is the cable that will meet all of today's capabilities and get you prepared for the future as it allows deep color rendition, lossless audio formats and faster refresh rates.

This evolution allows HDMI to keep up with increasing data transfer rates necessary for next-generation products. A PlayStation 3 or a Blu-ray DVD player at 1080p and 12-bit deep color with a 60 Hz refresh rate rate requires 6.68 Gbps of bandwidth. HDMI 1.3 reaches above this to allow for innovative products to come that will need even faster transfer rates as TV picture and audio becomes even more lifelike.

Why is HDMI Better?

HDMI connections give you fewer cables behind your TV connecting your components. Pictures are smoother and sharper, and high-quality audio is incorporated into the same connection. A developing feature of HDMI, called Consumer Electronic Control (CEC), adds awareness to your connected devices making them even easier to operate. For example, if your HDTV, DVD player and A/V receiver are all CEC-enabled and conected with HDMI cables, the TV remote can control the DVD player and receiver without a direct line of sight. The TV will send the commands to the other components through the HDMI cables.

What's the Difference: How to Know Which HDMI Cable to Choose?

Not all cables are created equal, and it's important to make sure the cable you're buying will meet your needs. If you're planning on connecting components that will require faster data transfer rates, you'll want the newest version of HDMI, and not the original HDMI 1.0.

It's important to get cables that are durable. They should be well-constructed with shielding to keep the signals clean. The longer the cable, the higher quality you will want to ensure that data isn't lost.

Even if you don't have an immediate need for high-definition,getting a well-constructed cable that exceeds current standards will future-proof your purchase - an important step in an industry that moves as fast as the consumer electronics industry does. If you're planning on installing cables in walls, you certainly don't want t rip out old cabling an start over.

HDMI cables deliver the true HD video and audio experience.
