<DIV>interesting resource.... I remember hearing Sarnoff library
had a flood .... pre- 2009 when these
folks took over...</DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV>makes me wonder what had been lost....</DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV>pretty fun... but the way they did some of
this really leaves me wanting for more...</DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV> - later post '45 ann. reports missing.. </DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV>-- sure would like to talk about the person that
scanned the RCA engineer... Where are the
wonderful covers!? Like the Radio age and RCA BRAODCAST
mags... the engineering ones had great color
covers too....the pages is a real low res b/w
yea you can read them but.....</DIV>
<DIV>you can lift from the ocr test pretty
well though and is good when you need to quote
something... cuts down on typing...</DIV>
<DIV> </DIV>
<DIV>guess I will keep collecting RCA ENGINEER in paper
form!</DIV>

<DIV>In the article "Engineering Color Videotape Recording," A.
H. Lind outlines the Quadruplex recording process, RCA's TRT-1
development, and RCA's approach to obtaining stabilized color playback.
</DIV></DIV>
<DIV><BR></DIV>
<DIV>"<SPAN style="FONT-SIZE: 12px" class=Apple-style-span>The basic
technique is to cancel out time "jitter" in the chrominance signal by
translating it to a higher frequency spectrum and then heterodyning this
translated signal with a signal which also contains the jitter and is of
such a frequency that the difference signal frequencies fall back into the
original frequency band. If this signal is derived from a signal recorded
on the tape, it will contain the same time jitter effects as those in
translated chrominance signal, but the difference signal obtained by
heterodyning will be free of the jitter because the errors have been
cancelled by subtraction.</SPAN>" </DIV>

<DIV>Written three years after NBC began time zone delay in 1958, it
offers a glimpse of how the network was actually several networks, patched
together at different times for transmission in different
dayparts.</DIV></DIV>
<DIV><BR></DIV>
<DIV>How NBC used recorders in New York and Burbank to achieve program
delay during daylight savings time (DST) involves the use of three
"networks." </DIV>

<DIV>The "A" network—or "live" network—received the live feed from NY
covering eastern and central US areas on DST. NY and Burbank both
rolled two tapes each.</DIV>
<DIV><BR></DIV>
<DIV>A "B" network was fed tape playback from NY delayed an hour for
southern and central areas <I>not</I> on DST. Two tapes were
running in sync during TZD to avoid glitches.</DIV>
<DIV><BR></DIV>
<DIV>Burbank played the A network feed to the western "C" network three
hours after the NY start time.</DIV>
<DIV> </DIV>
<DIV>Shows that originated live in Burbank would be performed at the
correct NY start time and fed to the A network, recorded in NY and
Burbank, and then played for the "B" and "C" nets as outlined
above.</DIV>
<DIV><BR></DIV>
<DIV>Viewership (and resulting ratings-related revenue) for shows in the
B-network areas was improved by delaying an hour. It avoided people
being outside when say, an 8pm DST show would have occurred at 7pm in
their area.</DIV></BLOCKQUOTE></BLOCKQUOTE>

<DIV>The extremes taken to maintain the same picture quality over days of

<DIV>Taping a two-hour show, done in three different color studios,
extending over nine days, is a formidable undertaking. In addition to
studio lighting problems, special precautions were demanded to insure
matched luminance and chroma levels at the studio control room and TV
tape room, if the successive tapings were to be free of flesh-tone
changes or other color differences. </DIV></BLOCKQUOTE>

<DIV>Differences between individual videotapes could cause as much as a

<DIV>NBC developed a procedure to match color from day to day, using a
reference tape with the NBC Color Girl and bars, coupled with recordings
made on the same piece of tape at the beginning of sessions. The
"day-of-session" tests were played back to the video engineer so he could
shade the studio's cameras to match the tape.</DIV>
