hipman2 said:In July of 1979 one night, I fell asleep while watching a movie on HBO. When I woke up at 5am, "Today" from NBC came on the air, on the cable system's HBO channel slot. Then it went into a test pattern again, then the cable company blacked out the feed until 2pm when HBO came on showing TV and radio promos for stations to use. At 3pm, the HBO channel went into pre-sign on mode until 5pm when it signed on again.
Can anyone explain that Today on HBO thing? I'm guessing that it was the first hour of Today from an hour ago refeeded for the Central time zone stations to use, and NBC refed the second hour of Today at 9am ET (8am CT) for Central affilliates to use.
If it was just a one-time anomaly, sounds like maybe the cable company was reconfiguring their dish(es) in the overnight hours, and temporarily had the "wrong" transponder feeding that channel. Maybe even by design -- perhaps they had to test something and needed a video source for that channel, but with HBO off until the next afternoon (boy, hard to believe that they used to NOT be 24/7, isn't it?), they just grabbed any old downlink that was convenient, and the ET/CT NBC feed just happened to be on the same bird (Satcom I).
But, wait -- would NBC have even been feeding by satellite as early as 1979? Had to be the East Coast feed if you were seeing it at 5 am PT, and no terrestrial Left Coast affiliate would have been carrying the show live at that early hour, so either satellite or long lines.
Any better theories?
