Swedish teletext 45 years - UK Vintage Radio Repair and Restoration Discussion Forum

In todays newspaper there was an article (in Swedish) about teletext in Sweden, or as we call it here, text-tv. It was 45 years ago it was introduced by the public broadcaster, second in the world after BBC. It is still going and is therefore the longest going teletext in the world.

It is of course not as popular as it was say 30 years ago but it is still used by many. Sports results, news, weather and TV program is still published continously.

I can't say I am using it but I like that some things stay as I have always remembered it.

There is even an online version of it

So how is Teletext being deployed today in Sweden, given it's transmitted in the vertical blanking interval of an analogue TV signal?

Attempting to answer my own question, it could be that some digital set top boxes have a Teletext encoder within the chip-set and can source the data from a digital stream and insert it into the VBI of the CVBS output.
Early itterations of our Sky Digibox did this.

Living in Sweden, I think the thing that has kept it going in subtitling in English. I don't have a TV anymore, but it used to be 888 I think.

In digital TV transmissions (DVB-T or T2) teletext is transmitted as ancillary data which are decoded in software in today's TVs.
It can be re-encoded as traditional teletext and inserted in the VBI of the CVBS output of external STBs used with old analog TVs.

Most DVB-T boxes can do this apart from the ones sold in the UK branded Freeview. Several countries in Europe still broadcast traditional teletext. If you have a satellite receiver and can receive German channels from Astra your modern TV should be able to decide the teletext if you connect the sat receiver via scart (not HDMI).
