Unless I understand wrong, one part of PSIP is the mechanism where your tuner scans for channels and it maps them at that time. I don't know of any TV or tuner that's actively scanning, and no, I don't see it being used as a redirect, because that would require broadcasting on the old channel.

I can only hope that throughout Jan. 2009, OTA channels run a banner as frequently as necessary saying, "You will have to rescan for channels on 2/17 and you'll need a converter box" or something like that.

Everybody SHOULD. Who knows what they will really do.

The way PSIP works is that your television scans for signals. It finds a signal between 698-704 MHz (commonly known as channel 52). Your television reads the PSIP information from the signal, and your TV learns a lot of things, including there are 4 broadcast streams on the signal, and they are called 5.1, 5.2, 5.3, 5.4. Your TV stores this information.

(In some cases, your TV doesn't scan for the signals, so you need to enter this information, or your TV downloads it from another source.)


Later on, when you tell your TV that you want to watch the broadcast stream called 5.1, your TV has already learned that 5.1 is broadcast on the signal between 698-704 MHz (commonly known as channel 52).

Now, after Feb 2009, the television station may move its signal from 698-704 MHz (commonly known as channel 52) to 530-536 MHz (commonly known as channel 24).

When you tell your TV that you want to watch 5.1, it will go to 698-704 MHz(commonly known as channel 52) and it won't find 5.1 there, since it has moved to 530-536 MHz (commonly known as channel 24).

So you need to do a rescan, and your TV will then find the signal at 530-536 MHz (commonly known as channel 24) with the PSIP information saying this is where 5.1 is located.

Good example:

But, if RF channel 52 has 5.1, 5.2, etc. as it's virtual channel(s), it will most likely either stay on RF channel 52, or move to RF channel 5 after the analog cut-off. Since TV stations have the option of returning to their old analog assignment after the cut-off (the virtual channel number).

So, then RF channel 5, may also be virtual 5.1, 5.2, etc.

Except - that channel 52 is "out of core" post transition - all Digital stations (full power) must be between channels 2 and 51 inclusive.

A significant number of my local digital stations are currently out of core and will be moving to their final assignments on Feb 17,2009 . I can think of 2 out of 7 that are already on their final assignments - everybody else is part of the shuffle dance....

:lol: I know I said I wouldn't be back on the thread for six months but I couldn't help letting everyone know that Walmart now has a large digital LCD countdown clock counting down the days, hours, minutes and seconds until the dream time for the shutdown of high powered analog TV stations. It's in the electronics department.

Yes - at my closest WalMart - it's with the Magnavox converter boxes.

Since you've chosen to come back. I'm still willing to take that bet.

How much?

I would bet you a beer. Betting any amount of cash would be just taking your money. I did read a recent blog that the coverage area of the DTV signals is much less than that of the analog signal even after going to a higher power transmitter. Outdoor antennas may be required for some of the viewers who now use rabbit ears. Another expense, another pain for those widows on Social Security.

I'll be willing to lose a few real dollars. Come on, put your money, where your mouth is. Say $100?

Probably because the digital signal is currently on UHF. If they return to VHF after the cut-off, that issue may be solved.

What did people do when UHF was introduced? They either had to buy a tuner, or get a new TV. That was before SS, but I'm sure there were widows then, too. But, I guess our society now considers TV a necessity, instead of a luxury.

I can say that I have the opposite experience. I get digital channels that I never got as analog channels.
