DTC 100 STB's Channel Mapping

[JimHall]

For anyone still having channel mapping issues with RCA DTC 100's either STB's or built-ins receiving DTV stations on 46.2-5, 28.1 or 8.1-4 that are not channel mapping over correctly try the following.....

Make sure that you go to the menus option for Off-Air Guides, select to receive Off-Air Guides.  The system should then ask you if you want to re-scan your antenna inputs, select Yes and let it re-scan.

The mapping should then show 8.1-4 as 10.1-4, 28.1 to 4.1 and 46.2-5 as 1.0-5.

Let me know if this in fact worked for any of you out there.

Yes this works well.  A few weeks ago when I saw people talking about 1-1 instead of 46-2 ect.  I went in and turned on the guides and remapped and now everything is neat.  1, 1-1,1-2,1-3,1-4,1-5,4, 4-1, 6, 10, 10-1, 10-2 ect.ect.  This is with the 61" RCA with the box built in.

I did that during the first live chat, and it worked like a charm.

Did I miss something somewhere with regards to mapping?  Shouldn't my set show CBS as 46-1 through 46-5?  Why is it showing as 1-1? I thought that was "programmed in" by the local station. I also thought the frequency range for channel 1 was reserved, I do realize that this frequency band is not really being used, but why confuse me?

Probably just me.....

The stations can send information on their data stream that if you have guide info turned on they will redo your tv to show the channels as the station wants them.  Even though 46 ect. comes up 1-1 it really is on 46.  So if you do this here's what you'll get.
Channels 4 & 28 will show up:
4 (channel 4) and 4-1 (channel 28)
Channels 10,36, and 8 will show up:
10 (channel 10) 10-1 thru 10-4 (channel , 10-5 (channel 36)
I know this is wierd but it helps you configure your tv so your significant other can figure out what channel to watch.  IE: Tuesday night "Judging Amy" switch from 1 to 1-1 for the HD broadcast.

Were you online for the first chat? Jim discussed the strategy behind this for quite a while.

Off and on Tom.  While I see the "marketing" reason, yes, it would be cool to be #1, I have found nothing that indicates that the FCC will be using the frequency range of 48-54Mhz for television transmissions.  Jim also mentioned significant monies spent to promote the brand that exists presently if I recall.  That has value also.

This document on the FCC site does start to talk about proposed spectrum allocation (about page 14), and although it's dated 1996, I have not found anything newer yet:

In all honesty, I probably won't spend much additional time looking (way too tiring on the eyes), but I would suggest that the:

JIM HALL: SO SOME PRETTY SMART ENGINEERS WITH MARKETING BEHIND THEM GOT TOGETHER AND STOLE AN IDEA THAT CABLE USES CALLED CHANNEL MAPPING

keep to their day jobs....  Personally, if I'm watching channel 58 I think it should say that.  The UHF assignment for channel 4 to 28 is only temporary, and I'd be willing to bet they will get the frequency band of 66-72Mhz back when the conversion is complete in several years.

Now I'm watching channel 46, my TV is saying it's channel 1, and my wife (and any other viewer)needs to understand that it's really channel 58 (CBS) if she wants to watch Survivor.

Now if channel 1 were going to be available, that's a different story.....

The latest HiPix software allows you to assign a station to a different number if you choose. This actually came in handy, because they also eliminated channel 1 from the ATSC listing at the same time. I was under the impression that this is also a capability of most STBs.

Joe,

That's a good idea, I'll look in my service manual and users guide.  Maybe there's something there.  Otherwise, I can route the output from my HD tuner to my modulator, assign it to channel 46, and loop it back into an analog input.  Of course, now this puts every HD station I tune on ch46, and degrades the picture quality. :-(

It actually may be easier to pick up WISC.....
