oowoowo !! super excellent and great at 3:41 ! when he power off all the system ! :) you think probably some geek comes to that old systems and use it again for transmitt some geeky stuff like kdv pthc data on video ?? LOL
They're going to need to work on the delay. Taking a full 3 second lag with WBBH's dt signal against the analog signal. How come digital is not "live" or "liver" than analog?
I don't know the exact reason but I will guess one reason is that that for the digital signal, they are buffering the video/audio so it can be compressed. Then, you could reduce the delay but the compression would be less efficient and the picture quality would suffer. As it is now, it's impossible for digital to be "as live" as analog, otherwise it would be unwatchable, and "liver" is out of the question.
Notice how WINK's button-push made it to air. If it were the digital transmitter being shut off, we probably wouldn't even see his hand reaching for it... wouldn't have encoded in time.
Digital TV is a like downloading an MPEG file (same encoding and bitstream even!), except the TV station beams it to you and the decoder box "plays" it as it gets it. The problem with MPEG is the encoder will naturally delay the video because it has to reorder frames, so that similar frames compress better (as P & B frames that encode only what changed). Typical encoders tend to gather 30-40 frames into a group and work on those, hence the 1-3 second delay.
Usually WZVN has a great signal, and WBBH has the crummy one, at least from where I used to live in Lehigh Acres anyways. Ah I remember the days, listening to the Macy's thanksgiving day parade outside while hanging the christmas lights. As a kid, always made me happy.
@312ustetok i know why they want people to buy a HDTV

GREAT! I watched my local PBS change format. It was pretty anti climactic.

Wow. I wish that I could have had a setup like this that day! Great video!

Analog has a delay too.
It's just that we viewers never noticed. We won't notice the digital delay either once analog no longer exists. It will feel live.

Analog's delay is measured in milliseconds.
Notice how WINK's button-push made it to air. If it were the digital transmitter being shut off, we probably wouldn't even see his hand reaching for it... wouldn't have encoded in time.

Because of the compression/decompression required.
