Guidelines for Posting in this Thread

Let's try to have a constructive discussion about this topic.

I know there are those who think the transition won't happen. Feel free to discuss that but do not get political please. I know, this is a government issue but try to keep the focus technical and social, not political.

Feel free to discuss "great found deals" or sightings of converter boxes, success or failure stories, or other DTV-related viewpoints.

Just like other non-DBS topics such as Blu-Ray vs. HD-DVD, we are going to keep only one thread on this topic. Other threads will be merged into this one or deleted.

Unfortunately we will have to delete posts that are too political or attack other users.

The DTV FAQ can be found here.

Have at it!

Good idea! There were more than a few of these threads popping up in the past few weeks.

I think broadcasters need to be more open about what their final channel assignment will be after analog shutdown. There's a number of stations now on UHF that will go to a VHF channel which could effect a decision on what antenna to purchase. Maybe sites like Antennaweb.org should note that when people are researching what to get.

Something eles that needs to be address is the availability of low cost battery operated set with ATSC tuners. A number of people have sets like this in their emergency kits to allow them to keep track of news and weather, those sets will be useless after 2/2009. I found one battery/ATSC set at Radio Shack but it was almost $200.

See post My Setup for configuration info.

What about radios?

That would work but some people prefer to be able to see what's happening vs. trying to figure out what a radar image would look like.

Here is the FINAL list of post-Feb-2009 Channel Assignments --> http://fjallfoss.fcc...CC-07-138A2.pdf

The column labeled NTSC Chan is the old Analog channel number. The column labeled DTV Chan is the new Digital channel number for post-Feb-2009.

Note that you may need to check nearby cities (and nearby states) to see all the channels you receive.

Upstream, I know that but does the average consumer even know that channel assignments will change let alone that they need to go to an FCC page to find the answers?

Ah, didn't think of that. Fortunately I've always lived in areas where extreme weather that would require some alternative communication with the outside world is rare.

I'm sure the prices of battery-operated tuners and portable TVs with digital tuners built-in will drop... eventually.

Didn't I read somewhere though that even though the digital channel number is changing, the tuner will/can still use the old analog channel when tuning on the tv set?

I think you're referring to PSIP, which is a way that your TV can still tune to 4-1 when you want channel 4, even though it may actually occupy the same place that channel 36 (analog) used to. That's part of every new TV with an ATSC tuner.

Forgive my ignorance... doesn't that mean that the channel assignment changes that Upstream posted a link to above is moot? For instance, my local ABC is currently analog channel 2 and is/will be DTV channel 38. An ATSC tuner will still allow me to tune to channel 2, correct? Which means most people won't notice any change at all if they have a built-in ATSC tuner, and those buying converter boxes won't notice a difference once they're hooked up.

That is correct, if your local ABC decides to keep putting out channel 2 via PSIP.

If, or when, the RF channel changes, it will "go missing" until you rescan for channels.

Or, the database is updated in your set-top, if it can't scan for OTA.

So, some people may, at first, think their local digital station is not broadcasting.

I agree that the stations need to do a better job letting people know what there permanent station assignments will be. Aside from the issues raised by others, there are people who are buying UHF-only antennas, assuming that no stations will move back to VHF.


My link above was intended to just be informational for those on this forum, not a replacement for the communications that the stations need to do.

That's the crux of the problem .. However, double checking the SF links, many are going to stay UHF which will minimize that particular problem. I did find a nice chart that someone put together for th SF bay area if folks are interested .. much more user-friendly than the FCC link, but only for one DMA ..

That feature was added to antennaweb in the last few days. But www.tvfool.com beat them to it!

Isn't that a bit misleading? PSIP in and of itself doesn't contain any program material. As I understand it, it CAN point/guide you to a new (active) channel. But then, I rather doubt that broadcasters will be allowed to transmit PSIP on a channel that they are no longer licensed to use.
