What is H.264?
That is one of the most common questions. While more seem to understand the concept, he says the how and why behind the
compression technology is still a bit of a mystery. The reason why H.264 is so efficient is that it uses a lot of complicated
computing algorithms to “pack pixels into a tiny box.” What many people don’t understand, Brown says, is that you need
software to unpack that box in order to view the video. And if you’re using older software, the process eats up a lot of computer
processing power. “When they’re told that a particular software can display eight to ten 1-
to 2-megapixel cameras at 15 to 30 frames per second, most people don’t think to say, ‘Show
me,’” Brown relates. “If you’re talking about viewing one camera at a time, no problem. Nine
or ten on the same screen? That's where a number of systems start to fail.” Unfortunately, he
says, this doesn’t usually show up in a demo, but only when someone is viewing video in a
control room or monitoring center. Perhaps what’s most unfortunate, Brown says, is that
the solution for avoiding this kind of failure is as easy as installing new software or
upgrading workstations to high-end gaming-type PCs.
