Rural General Suckitude

I don't know which is worse in rural areas...the fact that the phone lines are and have always been for shit, or, the fact that you can't even use good ol' rabbit ears to pick up any TV signals anymore.

Why can't you use rabbit ears? I can pick up digital stations using a wire coat hanger with no degradation in quality. It's digital, so you either get it or you don't. It's not like the analog signals that would vary in quality depending on the strength. Rabbit ears will work just fine.

The issue is that the digital signal has a sharp cutoff where you either get the signal or not. The analog signal would degrade over distance but still provide a viewable channel, even if the quality sucked.

This map of the coverage in the Wilmington test shows how the analog transmission had a farther reach. The digital coverage was helped by overlapping digital signals from nearby affiliate stations on the same network. But the area in orange basically lost all NBC coverage in the switch.

Re: Rural General Suckitude

And here I thought the FCC had conducted tests to ensure that the coverage would not be diminished when the switch to digital was made.

I wonder how this will impact satellite TV and local channel distribution. In areas where local networks were not included with DirectTV or Dish, you had to live outside the range of the local analog signal's reach to be eligible to get generic network broadcasts piped to your satellite receiver. I suppose the distance requirements will have to be adjusted accordingly.

Hopefully there won't be any situations that might cause one signal to bleed over the top of another. If that is even possible with this type of signal. I know with my radio stations I can make a mix of Mexican Radio meets Contemporary Jazz. This occurs late in the evening and I call this music style, Contexican Jazzio.

If I recall correctly, many stations whose frequency lies within the VHF range will actually be broadcasting with less power to prevent interference with FM stations. Plus they don't pass through physical objects (walls for example) as well as UHF frequencies.

Many of those stations are currently broadcasting in the UHF frequency range, but will switch to VHF after Feb 17, 2009.

For example Philadelphia's KWY-DT (CBS) is currently broadcasting on a UHF frequency (don't have it in front of me at the moment), but will switch to channel 3 after the switchover. That means people who can receive the channel now, might not be able to get it after the transition.

Thanks for link. After looking at that thread I came across this link that will allow anyone to stay on top of the OTA digital plans and follow thru.

»www.rabbitears.info/dtr.php

And if you do a zip code search and keep the mileage option to 40, you should be able to see what is/will be available digitally on 2/17/2009 in your area.

»www.rabbitears.info/search.php

I have tested for my area and can get all the stations listed with rabbit ears and a converter box up to about 35 miles away.

Here is an example of what is available when using search and listing tools:

Actually, in Philly, it's WPVI-DT (the ABC station) that's moving their digital signal back to VHF-Lo, not KYW-DT.

Oops, you're right. That's actually worse since WPVI-DT doesn't come in very well currently. I shudder to think of what it will be like after the switchover.

that would help increase bandwidth efficiency so you could get a better picture or sound, but not raw signal strength.

cell phones work because there are towers all over the place. If you paid $50/mo for tv service you could have similar land based radio coverage.

I agree there will be likely be changes allowed after Feb 2009 as stations/customers get some real world DTV experience. The real test will not be Feb 18, 2009 but spring of 2009 when trees leaf out. Folks that had good TV reception in winter may lose it in summer.

Currently with simulcasting of analog and digital TV bands things are pretty crowded. After analog goes dark, even with loss of channels 52-69, band will likely be less congested in most regions. That means interference will be less of a problem making it viable to modify signal strength.

Something many people may not be aware of is customer signal strength is a combination of many factors: 1) Transmit power, 2) Antenna gain, 3) Distance 4) Terrain 5) Multipath and other impairments.

We tend to think of TV Stations as being onmidirectional – transmitting equal signal in all directions but that is rarely the case. Stations design antenna to have difference gain in different directions. It is a lot more cost effective to double receive signal strength (3 dB change) by tweaking antenna radiation pattern to change Effective Radiated Power (ERP) then to double transmit power. There are limits to this of course but it is not just a matter of cranking up transmit power with commensurate increase in utility bill.

In the little testing I've done, the analog quality would have extra-high suckage. I've seen perfect DTV picture quality with no drop-outs when the equivalent analog channel was so snowy it was no more then a ghosted black & white eye-hurting remnant of itself. Looks to me that the DTV signals need very low S/N to work just great.

Maybe in some markets the DTV stations are running at reduced power before the transition date ? ? ?

This exact same argument was put forth back in the good 'ol analog cellular days. "My digital phone cuts out all of a sudden where I used to have analog coverage !" Truth be told, the analog coverage was so static-ridden and broken up it would take an experienced intercept operator to get any intel out of it "What ? What ?? Say that again - YOU'RE WHAT... ?!?!?!!?"

This could very well be caused by different Multi-Paths between the different frequencies the analog and digital are transmitting on.

It's not even just as simple as you either get it or you don't, all of the tv channels I get that are digital are choppy if I don't have the antenna adjusted just right for each channel I watch I have to constantly adjust my rabbit ears or the digital channels break up into little squares and then the screen freezes for minutes at a time, then picks up the signal again for a minute or two then cuts back out. atleast with analog you could still watch the show with out interuptions even though the picture might be a little fuzzy.

Well, we could at least get a crummy, snowy reception of Jeopardy if Uncle Bill, with a metal plate in his head, sat on the love seat near the window. It was something, just like dial up. Better than nothing at all, perhaps, or maybe losing TV is the best thing that will ever happen. With no TV, one might expect to see increasing levels of reading comprehension in those areas.

As jmn1207 See Profile posted about 12% of us rely on over the air transmission.

Conversion to DTV is actually increasing number of people using over the air antennas. OTA typically has better picture quality then Cable or sat because it is not recompressed to reduce bandwidth usage. In addition in these poor economic times I'd be willing to bet some folk are going back to OTA to save money.

That is not always true as these 2 Philadelphia, PA channels indicate. Check out the video bitrate column.

CBS isn't compressing and has only 1 digital channel to use their bandwidth.



But ABC cut up its bandwidth to squeeze in more sub channels.

Sorry, guess I was not clear. Stations can and often do broadcast multiple sub-channels.

What I meant was programs broadcast over the air are often recompressed by Cable and Sat providers to squeeze more channels into their channel capacity reducing quality compared to what one gets with OTA.

8.6mbps MPEG-2? Yuck!

Problem is, cable or sat is going to use WPVI's 8.6mbps ABC broadcast as their source. So no matter where you go, it's going to, at best, be that same 8.6mbps crappy quality, perhaps with even more artifacts introduced if it's transcoded to MPEG-4 or pushed through a cable company compressor to guarantee WPVI doesn't change their mind and up the data rate. It's unlikely that TV providers are going to go through the trouble to get their encoding equipment installed at a point prior to being compressed for OTA transmission.

You have, however, perfectly illustrated why I cringe when people say OTA is superior because it's "uncompressed". As you've shown it may be compressed quite severely! Many cable systems just remux the same quality data onto a QAM stream.

Agree, most people don't realize an uncompressed 1080i or 720p raw bit stream is over a Gigabit per second. Lossy compression is used to reduce it to around 20 mbps.

Compression can be used to reduced data rate to anything desired. However, greater the level of compression the poorer the image/motion quality.

My neighbor put up an outside antenna just for that reason, much better signal than Dish or Comcast, but he kept Dish for the extra programming he gets.

We and a few of our neighbors who have gotten the boxes have seen a bit better signal on the digital modes than with the analog. But the digital modes do have some odd display formats (vertical letter box vice horizontal?), but that may just be the wife not wanting to adjust for the different modes with the control. (caveat: I do not watch TV very much, very little worth watching any more)

70 miles may require Herculean effort, unless you or transmitter are very high.

Check out the TVfool site and see what estimated signal strength is. If estimated signal is better then about -110 dBm you have a chance. Try modeling at different heights. But putting up a tower is expensive. At that distance weather will be a factor so no matter how good the antenna you may not be able to get good signal 24/7/365.

Good Luck

In the case of the testers in Hunterdon County, NJ (~40 miles to NYC and Philly), it was "You don't". The signal strength is just not enough with digital where there once was with analog. For these testers, there was 100% loss of all currently served broadcast channels (2-13).

We're not talking rabbit ears either... Roof antennas only brought in new non-English channels instead. One tester went as far as to head over to radio shack for help, and found out he had to purchase an amplifier to supplement his roof antenna too.

Not directed at you, but to rant on... The sad reality is, as it is now, is that people would have to shell out $300 for roof antenna if they don't have one... and an amp for $?, not to mention the cost of the converter (even with 1 coupon).. While some may say, switch to something else... That is not the point here. Broadcast TV is supposed to be free to masses. Should people buy roof antennas and amps for the portable TVs? I know I'd miss mine in the garage that I also take camping.

If the FCC can't handle DTV in a metro-NYC area by calling it "rural fringe", what's going to happen in all areas that isn't within 35 miles of a tower? A coupon for 1 converter isn't going to do it.

Start with the current analog channels. They're all yellow or worse RIGHT NOW, except for the nearby WNJB. That's your baseline for comparison. So right off the bat, you're already going to need more than rabbit ears, EVEN FOR ANALOG.

Post transition, 5 goes to red. 12 and 13 were already red as analog stations. 10 is not red, it is yellow. In the yellow, that location will have two ABCs, two NBCs, two CBSs, two MyNetworkTVs, and a couple of other stations. Just 3dB down and they'll pick up Fox and CW. And note that TVFool is pessimistic: I'm currently picking up a channel predicted to be -110 dBm at my location, in the gray, with a modest-sized antenna.
