I wanted to direct everyone's attention to this week's installment from Mark Schubin, which contains too many interesting tidbits this week to mention here. It's at the Digital Television website:

I find the following from Mark's post to be the most interesting:

Quote:
- May 1, 2002 -
- Including weekends and holidays, there are just 79 days to
go.
- The action is picking up. The FCC just released figures it
says are from January 18:
- 1425 construction permits or licenses have been
issued. That's 84% of the U.S. DTV stations due on the air:
<http://www.fcc.gov/mmb/vsd/files/dtvsum.html>
- 172 U.S. DTV stations are fully authorized.
<http://www.fcc.gov/mmb/vsd/files/dtvonair.html>
- Another 59 are operating under temporary authority.
<http://www.fcc.gov/mmb/vsd/files/dtvstas.html>
- In the top-10 markets, where 40 ABC, CBS, Fox, and NBC
stations were due on the air May 1, 1999, there are 36 fully authorized
and one operating under temporary authority. Two more WERE on the air
in New York until September 11. But, not counting those two, one has
yet to make it, almost three years after it was due:
<http://www.fcc.gov/mmb/vsd/files/dtvstat.html>
- In markets 11-30, where 79 stations were due on the air
on November 1, 1999, 68 are fully authorized and another seven are
operating under temporary authority, leaving four to go:
<http://www.fcc.gov/mmb/vsd/files/dtvstat11.html>
- 170 stations have asked to change DTV channels:
<http://www.fcc.gov/mmb/vsd/files/dtvchan.html>
- According to the NAB, as of today, there are 249 stations
operating in 86 markets, but fewer than 200 of those are commercial;
1288 commercial U.S. stations are to be transmitting DTV by May 1:

Found these first-person observations from this week's edition (halfway down) summarizing an advanced motion imaging conference interesting.
  • Someone reported on a vintage CBS study that the highest average projected film resolution measured from observations in different cities was 875 TV lines per picture height in Hollywood but 750 lines elsewhere. (Believe that multiplies out at 1335-1558 on a 16:9 set.)
  • A 1920 x 1080 24p HD "Independence Day" was played at a little over 6 Mbps and appeared 'fine', sharper than a DVD of the same scene.
  • Someone from Sarnoff Laboratories reported we're approaching the MPEG-2 limit of visually lossless compression with SDTV at 3 Mbps and HD at 15-18 Mbps. MPEG-4, he said, might provide about 15% more.
