HDMI Cables: An Overview
Ever since HDMI-capable devices started to come onto the market a few years ago, there have been a lot of questions--and a lot of misconceptions--about HDMI and HDMI cables. A "FAQ" on this subject, as we've found in trying to assemble one, would be so long that the better way, we think, to provide some answers is to simply address the major question groups: What is HDMI, anyway? What's in an HDMI cable? Why might I, or might I not, want to use an HDMI Cable as opposed to, say, component video? What makes one HDMI cable better than another, and when does it really matter?

So, What is HDMI, Anyway?
HDMI stands for "High-Definition Multimedia Interface." The HDMI standard was developed by a consortium of consumer electronics manufacturers and content providers, to address what, from the content-provider industry's standpoint, was a serious problem: existing analog video formats such as component video are not easily copy-protected. HDMI, being digital, provides a perfect platform for the implementation of a copy-protection scheme (HDCP, or "High-Definition Content Protection") which enables the content providers to limit the consumer's access to, and ability to copy, video content.

As we'll see, HDMI is a horrid format; it was badly thought out and badly designed, and the failures of its design are so apparent that they could have been addressed and resolved with very little fuss. Why they weren't, exactly, is really anyone's guess, but the key has to be that the standard was not intended to provide a benefit to the consumer, but to such content providers as movie studios and the like. It would have been in the consumer's best interests to develop a standard that was robust and reliable over distance, that could be switched, amplified, and distributed economically, and that connects securely to devices; but the consumer's interests were, sadly, not really a priority for the developers of the HDMI standard.

What's in an HDMI Cable?
The HDMI format is essentially a digital version of RGB analog video; the principal signal in an HDMI cable is carried on four shielded twisted pairs (yes, just like a CAT5 cable, but with shielding added), one of which is for red, one for blue, and one for green. Sync pulses, which tell the display where a line or frame ends or begins, are carried on the blue line. In some cases, rather than RGB video, HDMI carries Y/Pb/Pr "color-difference" video, which represents the same information as RGB but differently conveyed. The fourth twisted pair carries a digital clock signal, and seven miscellaneous additional conductors carry some signaling and incidental functions.

Why Might I Want to Use HDMI?
HDMI is often the handiest way to connect two devices; at the moment, that's really the best reason to use it. However, in the future, it may become necessary to use HDMI connections with certain devices, or certain recorded media, in order to get full HD content. Beyond that, there aren't a lot of compelling reasons to use HDMI as your connection method. Most of the arguments we hear are based upon common misconceptions about the benefits of HDMI, and one really needs to get past those to understand just what the real reasons to use--or not to use--HDMI are.

HDMI Myths and Misconceptions:
1. "Only HDMI carries High-Definition Signals." Wrong, wrong, wrong. Analog component video and RGB both support high-definition resolutions, and what's more, they're more robust and dependable over distance. There likely will be cases, in the future, where high-definition signals are available from certain source recordings only through the HDMI port, and only downconverted standard-definition video will be available on analog outputs. However, as of this writing, none of the recordings available on high-definition disc formats have the "flag" set to limit HD output to HDMI. Some "upconverting" DVD players will output their upconverted signals only on HDMI, but the value of DVD-player upconversion ranges from dubious to clearly negative as in most cases it only adds an additional rescaling step to the signal chain.

2. "HDMI provides a pure uncompressed HD signal." This is one of those statements which is true if taken in a wholly irrelevant sense, and untrue if taken in its only meaningful sense. Unless you work in a video production facility, chances are that you've never seen uncompressed HD video. That's a shame, because it's gorgeous; side-by-side comparison with, say, an ATSC broadcast signal or an HD-DVD signal can be a rude awakening, and just serves to highlight how heavily-compressed and artifact-laced all of the HD video sources we view are. No broadcast, and no recording medium, on the consumer market provides uncompressed HD video, and none are likely to do so in the near term.

So what is meant by the assertion that the HDMI signal is uncompressed? What this too-often-repeated statement actually means is that the signal is not further compressed when it is translated from its source format to HDMI. But the same is true of all source-to-display baseband video formats; component video and RGB are not compressed after the signal is decoded from a DVD or a broadcast signal. The assertion that HDMI is "uncompressed HD video" means only, then, that HDMI is no worse in this respect than any competing video format.
