Yet another way your TV is obsolete, sort of.

If you scoured all of the details on the recent HDMI 1.3 release (and who didn't?), you may have noticed the inclusion of xvYCC and Deep Color. These are two different things that together will theoretically make displays' color more realistic. The short version is this: Deep Color increases the available bit depth for each color component, while xvYCC expands the overall color gamut. Sure they do, but why?

There's a whole lot of stuff that makes up a digital TV signal. Here's a primer on how it works.

In the beginning, there was analog television. You aimed the antenna, tuned in the channel, and then sat back to watch as the amplitude-modulated pictures flashed on the TV screen and the frequency-modulated audio blared forth from the speakers. Some time later, analog TV added color by shoehorning in a small signal with the necessary information amongst those amplitude- and frequency-modulated pictures and sounds.
