Millions of Brits Lose Ceefax News Service

judgecorp writes "Millions of Britons have lost access to Ceefax, the real time information service that has piggy-backed on blank lines of the analogue TV signal since the 1970s. Analogue TV is being switched off, and the low-res news service looks to be going with it. From the article: '“Although we won’t be saying our proper goodbyes to Ceefax until later in the year when switchover is complete across the country, I wanted to send a note of reassurance and a reminder: our digital text service, available via the red button to people who use cable, satellite or Freeview, provides national, local and international news, plus sport, weather and much else besides,” said Steve Hermann, editor of the BBC News website.'"

The title and summary seem to suggest that the system as a whole has had a failure of some kind, though it's nothing of the likes. It's just the analogue > digital switchover means that people will "lose" access to it, however the BBC provides digital services anyway.

It was generally the easiest way to get a TV schedule, especially once the newer TVs came in that did caching for pages (each of the pages would have its content updated very few seconds to scroll through things that were longer than a single page of text - newer TVs would record these and let you page through them without waiting for the next page to be broadcast).

Such caching makes a massive difference, but it's worth remembering that it's a luxury that wasn't- and couldn't have been- possible in Teletext's heyday. The early sets could only hold the page that was being displayed, and if you wanted to change the page (or wait for the next page in a set of (e.g.) 4 to load) you had to wait for it to be transmitted again, which could be around 30s. (IIRC some later sets cached a few pages, but it was still limited).

The experience of Teletext I remember from the older sets was that of having to *wait*. Don't get me wrong- it was amazing for its time (it actually came out in the mid-70s, before even the Atari VCS)- but it still had its limitations.

I got a new TV in mid-2010 and I was very impressed by the speed of the Teletext- it was obviously caching the pages, and the performance was massively better than the waits I remembered from before. This made a huge difference in usability, but as I said wouldn't have been possible in Teletext's heyday.

The reason is simple- a single page (40 x 24 characters) would take just under 1 KB to store, and back in the late 70s / early 80s even just a few extra kilobytes (1 KB for every page you wanted to cache) would have massively increased the cost (e.g. even the Vic 20 computer only had 3.5K or whatever, the unexpanded ZX81 came with 1KB and the 16KB "ram pack" was £30, around £80 in today's money).

By mid-2010, even the few *megabytes* that would be needed to cache every page on all five main channels would add negligible cost to the electronics, so there was probably no reason not to. But that amount of memory would have cost ludicrous money (tens of thousands of pounds) even in the early 80s, and probably an order of magnitude more when Teletext first hit in the mid-70s.

Of course, six weeks after I got that set the analogue signal (and old-style Teletext) was switched off with it in my area, so it was kind of moot. :-/

That said, I did remember feeling that Teletext's time had been and gone.

And yes, this story is in the British news *now* because up-its-own-arse-oh-so-important London is being switched off. They're not the last area to switch over, and they're *far* from the first.

Yes you're right. In fact if you just consider England, not Britain, then 1/3 of the population lives in London or the South-East. This isn't a good thing - it leads to ridiculous imbalances in employment and property prices - but it's the way it is. And population density aside, London has a much higher concentration of newsmaking entities (eg. Parliament, the City (financial district), many cultural/arts organisations). I understand the frustration people living in, say, Manchester or Birmingham feel about the London-centric news but the fact is that very little happens in your cities which is of national significance.
