     Aside from the "features" (such as a picture within a picture) digital
TV seems to be a dud.  Jeezze, we can't even make an ANALOG tv set correctly,
who wants an el-cheapo, very poorly designed digital set?

     The Intermetall-AG (ITT Germany) chip set has evidently fallen flat on
its face.  I expected about fourty zillion manufacturers to offer top line
digital sets, but why bother?  However, you *may* see frame stores which 
convert the refresh rate from 2:1 30 Hz (60 Hz) interlace to 1:1 60 Hz
interlace, effectively eliminating the line structure in the image. We've
been playing with this for some time with medical images and getting rid
of the line structure is the neatest thing which could happen to NTSC.

     Meanwhile, I'll just watch my Conrac professional monitor and Tek
demod, and hope that receiver manufactuers can get their act together.

     (Aside from this, for you HDTV fans) - my attorney just got back from
the winter CES over in Las Vegas, and is head-over-heels in love with the
HDTV system which one of the Japanese firms was showing. It is allegedly
35 inches diagonal measure, 5:3 aspect ratio, and more than 1000 lines.
The video bandwidth is supposedly a paltry 20 mHz.  He thought that the
interscene colour detail was "excellent." Other than that, he thought that
the CES was rather boring.  I hope that I can join him this summer at
McCormick Place (or wherever it is)......
