Smarter and smarter


Just when I thought I was getting a little smarter and gaining some knowledge of fibre optic cables, along come something called HDMI cables. So, being a person who likes to find out things, I went in search of some information, and found that HDMI are the new version of DVI. Confused?
DVI stands for Digital Video Interface – in other words, in real English, it means something that can be used to connect something else to a PC or home theatre system. And because nothing stays around for long these days, DVI is being replaced by HDMI, which means High Definition Multimedia Interface). But the good news – apparently – is that you can connect a DVI to an HDMI and neither will complain.
Ain’t that swell?
I guess it’s an improvement on the usual approach which requires you to go out and buy a whole new set of cables and plugs and whathaveyous because the manufacturers couldn’t be bothered to do anything that would be compatible.
However, there’s more good news. (This post is just full of it!) HDMI have something in common with our friends, the fibre optic cables, and that is that they don’t just carry one signal at a time. Firstly they carry a digital audio signal. Then they have room to send a digital video signal along the line. And, wait for it, they have room for future bandwidth as well. This means that you can be playing computer games on your home theatre while watching a DVD movie, catching up on the latest episode of your favourite tv program, and perhaps keeping up with the sport as well.
Who said modern people were dumbing down?
