ATVEF-A is only line 21, 2 characters on the
Yes, I see what you mean. I have digital TV at home (Cox in San Diego, CA).
They give you a set top box which enables analog TV and digital (MPEG)
to essentially co-exist. Its BOM is probably not much more than $150. It
is
not expensive to get a DiSH, either. I just don't see the major network

In the UK digital terrestrial is all running as is digital cable/satellite.
The proposal is to turn off analog about 2006 I beli
By "below discussion", I meant using a DSP, hardware or significant amounts of
processor time to decode the info in lines 10-20. All that effort addresses
the problem of decoding ATVEF data from an analog video stream. Obviously the
same data could be sent in an MPEG stream.
The other problem i
I agree HDTV is a long way off, but not digital TV, which is the same picture
size as analog (~ 640x480 for NTSC) but digital. DirectTV is digital TV, at
roughly 4-5 Mbits / second. AT&T is offering digital TV all over the place, or
at least claims to be - I'll see when they offer it to me, sinc

Yes and No...
The current ATVEF-A standard is for analog video, but the standard is

You mention "the next few years" - but in the next few years video will be
going digital; much of it already is. Isn't all the below discussion
relevant only to analog video? With digital video, ATVEF-type information
wouldn't be encoded in specific scanlines, would it? Does ATVEF address

I believe the standard you're referring to is ATVEF-A, see:
http://www.atvef.com/library/spec1_1a.html
The ATVEF-A data is on line 21 of the odd frames, along with the CC
data. It's teletext-2 format (so you can differentiate it from CC
data). Try watching some of the mid-afternoon gameshows
