- If memory serves, a dozen or so years ago several manufacturers offered tvs that
- could 'read' data contained in the vertical interval. None of them seem to wav-
- ing flags about the capability today. What happened? Do all of them do it now
- (putting the capability on par with electronic tuning thus eliminating any mar-
- keting advantage)? Were the results so unimpressive/detrimental the idea was
- dropped? Has the data been changed/eliminated so it's no longer useful/access-
- ible?
-
- If vertical interval data is still used by televisions, what do most (esp. svhs)
- vcrs do with it? Do they just record the data and pass it on to the set on play-
- back; make adjustments based on the data, not record it and generate their own
- on playback; or both adjust to and record/playback the original data?
-
- If someone who's got the line on this could post/email, I'd sure appreciate
- it...
