| Digital telly. What's that all about then? We're all told how wonderful it is, and how it's going to save the world. But if you were stranded on a desert island, would you know how to receive the latest series of Lost on C4 using only a bit of tinfoil and the juices of a curious plant? No. Of course you wouldn't. But at least with analogue you felt you stood a passing chance: it's just a radio with a big light in it and some magnets, right? With digital you're screwed. There's no way you can piece together an MPEG-2 decoder from twigs and bracken, so don't even try. For a start you'd probably be breaching some copyright or other. But how is digital telly structured, in a basic and uninvolved sort of way? And why does one channel look crummier than another? I unscrew the back in a desperate attempt to understand. This is what I found among the dust and dead jumping-spiders. | CONTENTS: 1: Multiplexes 2: Resolution 3: Groups of Pictures 4: Bitrates 5: Sound 6: High Definition |
