WPTV Ch 5 Analog Shutdown - DTV Conversion - Frequency Retune June 12th, 2009 @ 5:45 AM

The end of over 50 years of analog broadcasting by WPTV CH 5 in West Palm Beach, FL . Chief Engineer shows step by step how this televsion station converts their digital transmission from the temporary channel (UHF 55) and move the VHF CH 12. And then the final analog shut down. This was the only station that took the time time to show their viewers the process in the South Florida Market that I was able to find. Kudos to WPTV, conversion well done!
Should you have any problem viewing WPTV, the station's viewer hotline is open. Call 1-800-345-WPTV (9788).
WPTV began broadcasting on August 22, 1954 with the call letters WJNO-TV. At sign-on, the first words heard on-air were from control room director Vern Crawford: "The power has just been turned on for WJNO-TV channel 5 by Frank M. Folsom, President of The Radio Corporation of America."

I saw that as well, my guess is that the ENG truck that was sending the feed to the studio might have had a glitch and it might be the way they try to correct frame loss or errors with some sort of repeat of a few frames prior. I hear this all the time with Sirius radio where they through in a little sample of the previous audio when you get frame loss. It sounds like reverberation effect added.

There is another video someone put up that is the actual analog recording, you should see that one.

Yeah. I Guess. luvencl, WPTV Changed There Look On You Xfinity Box, After The DTV Switch All Your Programs Is Been Changed. But luvencl, You Are Watching WPTV 5 On Xfinity [Comcast], So That Means That You Are Not Effected!

[MrKashmire123]

That's good of you to switch before the big switch so you can see it for yourself!

@luvencl but did you see a black screen after he flip the old UHF?

I'm thinking that the chief engineer should have kept the station's signal output continuous by first firing up the VHF digital transmitter, then shutting down the analog transmitter, then putting the VHF digital transmitter on the tower, then finally shutting down the UHF digital transmitter.

so cool!

Look at the clip again at 2:33 into it. He pressed the "operate" button and then the tranmistter came up about 10 seconds afterwards. It first started at 0% and went to 73% power and then he walked over to the old UHF DTV transmitter. By the time he turned the corner, the new RF CH 12 transmitter was already at 100 % power. The "warmed-up" period is actually putting RF out over the air, but not a full power for the first 15 seconds or so.

[luvencl]

Yes, digital stream.

I was watching the conversion on Comcast and everything was OK except just a few seconds after Dave switched off the analog, there was a sort of ghosting. It was more of an echo or adjustment of some sort. Do you know what that was? (It happens at 4:10 in the video)
