Instead of being 'request-driven' like the internet, teletext just sends each frame to you in sequence, over and over.
If you had fast enough hardware (and I mean really fast), you could probably grab a complete snapshot of all the pages broadcast in about twenty or thirty seconds. Instead, we typically fetch a page, then fetch another page, and so on.
Wir empfehlen Ihnen daher die Mobilversion von ARD Text. Am besten dann gleich ein Lesezeichen für die Mobilversion setzen - dann geht's beim nächsten Mal schneller.If you are viewing teletext with a television, then it isn't all gloomy.Many televisions tend to try to speed up teletext by...

If you are viewing teletext with a computer, then how you can benefit depends a lot upon the capabilities of your teletext hardware.On the other hand, though, the clock signal (an extended packet, not the clock at the upper-right of the teletext page) is useless for any television (although some TVs display the channel identification that is also present).It is used, instead, by a number of video recorders to set the internal clock correctly. Teletext software uses it to accurately update your computer's internal clock.
