Internet on the telly
Around fifteen years ago, a 28" television rattled off the Philips production line - in an era where the UK just about had 5 terrestrial channels. Tonight, it showed me video from the internet. Here's how: The internet arrives from the outside world through a filter and into an ADSL router. Out of the router via a short length of network cable, it enters a powerline network adapter and through the domestic 240v power system at 130Mbps. At the other end it comes out the socket, into a 4-port adapter and through more Cat5 to the FreeSat box. There, it travels the short distance to the TV through a SCART lead and lo... BBC iPlayer arrives on the screen. It may not be a holiday on the moon, but it's a little bit of future.
