I believe that the UHF digital channels are more picky than the VHF analog chanels they are temporarily replacing in most cases. And that is the comparison most folks are making. The fact that an analog picture at the same power and same UHF frequency would look crappy doesn't change the fact that the current actual analog VHF version of a particular channel looks pretty good while the digital version is breaking up. Things should improve when they go back to VHF. They aren't going back to VHF below 187 Mhz. The lower ones are being given up permanently from what I've read. Jim But the current situation is not helping public confidence in digital OTA. You believe that analog OTA signals are much more robust in that they are more reliable as far as reception? Analog TV does have the advantage (if you can call it that) that even if the signal is weak, you will get something. If it's that bad, it's probably not watchable anyway because of snow, herring bone, whatever. I guess it depends on what is meant by "watchable". Continuity is more important to information transfer than clarity of the individual elements as long as the necessary elements are distinguishable. It's like the difference between reading a book with faded print but legible words and reading a book with missing words, sentences, or paragraphs at random intervals. In the first case, you can follow the story. In the second case, you can't. A fuzzy picture is only distracting at the beginning before you get into the actual content you are watching. But random periods of silence and frozen picture are downright disruptive and extremely frustrating each time they occur. joemooreaterolsdotcom |

The UHF channels 52 to 69 are being taken away from TV broadcasting. VHF 2 to 13 and UHF 14 to 51 will remain. However, not many TV stations are selecting the low VHF channels 2 to 6 (55 to 83 MHz) for digital broadcast after the analog shutdown. The stations that have are mostly rural stations that believe that the range of low VHF outweigh potential interference problems. There is no announced plan or even serious study by the FCC that I have heard of to take away low VHF channel slots. However if few stations are using low VHF channels after all the low power stations and repeaters have also been converted to digital, one can foresee several of the low VHF channels being shut off and turned over to other purposes. You have complained that your reception is badly affected by trees which is understandable if all your digital stations are UHF, especially in the upper UHF channels. Are all your stations at "full" power on the digital channels? What is your antenna and setup? There are huge differences in performance between UHF antennas. If I were at long range, all the stations were in the same direction & in UHF or upper VHF, and I had the space to mount it, I would get the Channel Master 4228 8 Bay bowtie. This is the UHF antenna of choice of many for challenging conditions. If you have already tried it, then you are in a difficult spot for OTA reception. Alan F |

Retailers are selling receivers, promoting them, broadcasters are promoting OTA and OTA is competing with cable and satellite. Right. It can't be because OTA receivers are more expensive in the US because they have to receive High Definition content, and therefore need more memory and processing power. No siree it can't be. And it can't be because retailers prefer to stock satellite receivers, from which they receive a cut of the sign-up fees. Has to be the modulation. Definitely. Hey Rain Man, when's Judge Wapner on? |

We wait for winter for the trees to shed so we can get better reception. We switch to the NTSC channels for relief, knowing that those will be going away in a couple of years. We are resolved to the fact that a high percentage of folks will be forced onto cable or satelite in 2009 and we are a part of those. Who won? The cable companies. Maybe we will put our $60 a month into DVD's or Blue Ray..........(:} I agree with you. I looked at cable ND dIRECT TV . i CAN NOT IMAGINE HVING TO LEASE A RECEIVER. |

Just difficult for OTA reception using an inadequate modulation. Would work fine with any of the COFDM based modulations, DVB-T/H, DMB-T/H or ISDB-T. Reception problems in the US are political in nature. Bob Miller |

OK......I used the industries term for the antenna.....lets not split hairs. For your sake, I will call it just a UHF Antenna. 4 Bay being the latest tried. A UHF antenna won't pick up all digital stations. Only those that broadcast over the UHF band. So you may need a vhf antenna too. Also an 8 bay UHF antenna might work better. That's what I use. Now....Here is what is happening here in Seattle. I don't know about your area. I've heard from many people in the Seattle area that doesn't have a problem. As for your tree..........I have a virtual forest between me and Seattle and I am not even in the country. I sit on a hill and if you know the hills in the suburbs of Seattle, the trees are like weeds. They form walls of foltage 100'+ high. I am not unusual in this area.....Everyone I know of is dealing with tree issues. I don't even have clearance for satelite....and the trees are not even on my property.

Well in Japan which only started broadcasting HDTV OTA a couple of years ago and where OTA DTV ISDB-T (COFDM based) modulation is used and where Mark will tell you only selected areas can receive limited content they are selling EXPENSIVE HDTV sets with integrated OTA COFDM receivers at an incredible rate. Also in Japan since they have a limited market, ISDB-T has only been adopted by Japan and more recently Brazil, they have more expensive receivers. And in Japan the customer has a choice. They can chose to buy an integrated HDTV or one without an OTA receiver. A high percentage of them chose an integrated set WITHOUT A GOVERNMENT MANDATE and with little coverage and with little content. While in the US with a lot of content, total coverage and therefore lots of incentive our Government has decided because of the lack of interest by the broadcasters, the public, manufacturers and retailers that they had to have a MANDATE. Even with the mandate there is still little knowledge of or interest in OTA DTV in the US. The first market that is big enough where COFDM based HD receivers will be sold using the world standard OTA modulation, DVB-T/H, will be France. This will be the first time a significant sized market will see the sale of HD COFDM receivers using the world standard DVB-T. Both Japan and Australia are limited. Australia by population size, channel size and a few other peculiarities. Japan just because it is a one country market for the modulation, Brazil is a not factor so far. France on the other hand is one of many DVB-T/H countries though the first using it for HD. I expect to see low priced HD receivers there. US 8-VSB receivers are high priced because this modulation requires a lot of silicone to operate, a lot of continuing work to fix and a market that is small. The manufacturers have not had much faith in 8-VSB and retailers have been burned many times with bad receivers that are returned and sold as open box specials. Broadcasters in the meantime concentrate their money on Congress and must carry of multicast content. Expect to see a lot of multicasting once this is resolved. Bob Miller |

"With digital, you don't have that problem." WHAT problem? You mean, you don't have the choice of watching that "something" with snow, herringbone, whatever--because with digital, it just AIN'T THERE. Period. At my house, all digital stations come in crystal clear. None of the analog stations do and a few are so bad that they are unwatchable because of all the interference. You seem to be saying that it's a "problem" to have a picture with analog artifacts, and that digital avoids the problem by simply not giving you the picture at all! What I'm saying is that the digital signal is not subject to the same common interferences you get with analog. Giving me some picture isn't the problem. The real problem is not giving me any picture at all, just dropping it out to a blank screen. With the analog pictures I get on some channels here they might as well be blamk. You can't make anything out watching them. 45 miles from the towers and huge power lines not far away that really screws up the lower vhf channels but doesn't affect the digital channels. It may be different for others, but I don't watch others TV's.:-) -- Want the ultimate in free OTA SD/HDTV Recorder? http://mythtv.org http://mysettopbox.tv/knoppmyth.html Usenet alt.video.ptv.mythtv My server http://wesnewell.no-ip.com/cpu.php HD Tivo S3 compared http://wesnewell.no-ip.com/mythtivo.htm |
