Teletext

If you tune in UTV , CH4, CH5 etc (BTW I know they are encrypted !!) could you get teletext through them ???

Youi can with a FTA receiver. Why don't you try it!!!

I get all the Irish TV channels Teletext on my PC Sat receiver (which caches *ALL* the pages and allows text search on entire "magasine"). No sound or picture. Makes TV based Teletext seem fairly dumb.
You can click on page numbers, select sub pages instantly and copy/popaste to windows apps or even generate Web site automatically with all the pages.

In theory, yes.

In practice, however, UTV does not carry teletext on digital satellite, and C4 & Five only carry their own channel information pages (C4 is from page 300 onwards, Five is p500 onwards, IIRC). This is down to the license agreements with the company that produces & maintains Teletext.

Ironic that
CNN has good Teletext and the USA still does not have such a service.

Teletext is easier to use and faster than "Digital Text"

Teletext doesn't messup a recording "Digital Text" does

Teletext *IS* digital.. The digibox has to receive it on a separate stream as it can't be fitted inside an MPEG2 Picture (Analog pictures have "empty" bits you can sneak digital signals into)

The Digibox could even do teletext and a 1/4 screen video just like the new "Digital Text", just by SW update. Non-Teletext TVs could then "see" teletext.

Different viewers of the same Digibox channel can watch different teletext on TVs , but everyone has to see the *SAME* digital text page, even the VHS...

Teletext works on PC and FTA satellite Digital Receivers and "Digital text" doesn't

I've read in What Satellite mag that BBCi is to get a big upgrade during the summer. Apparenlty, it will have as much content as Ceefax and will be much faster. I will look forward to that!

With modern "authoring" packages (magic of XML etc) you can easily produce the same content formated for teletext, Web and "Digital Interactive Text".

So only extra cost of teletext (which they presumably want for Analog Terrestrail) is the Satellite stream. Compared with Audio or "Digital Text" this is a tiny bitrate (=tiny cost) so why don't ITV and BBC transmit full teletext on Satellite?

Well, RTE are to introduce a digital text service on Sky some time. They've signed an agreement with whoever does the software. Don't know when we'll see it though. Maybe end of this year or early next year
