That isn't what I said and you know it. What I said was every digital tuner HAS a scan feature. Period. End of my statement. It isn't the tuners fault that all of the stations are not in the same direction, nor is it the stations fault nor the viewer. It is a fact of life.
Depending upon how various channel tuning/selection issues are implemented by receiver designers, The PSIP channel "remapping" regarding stations whose DTV RF channel # is different from PSIP VCT Major channel #(which is and will be most of them) may be a problem in SOME or MANY cases for average Joe and everyone else(not just the "blue hairs") and his "rabbit ears" mainly because the PSIP from any given station can't be decoded or used unless a signal(from each and every station in his area it's possible to receive) sufficient for a signal lock has been acheived by the receiver for each and every station in the area it's possible to receive.
We shall see won't we. So far, the people I have talked to, and this is people of all ages since digital went on the air in my market 6 years ago with every conceivable antenna from rabbit ears on the TV to mega antenna systems on towers, PSIP and channel mapping HAS NOT BEEN AN ISSUE. I suspect the same can be said in the majority of the country as well. The sky IS NOT falling. There ARE people watching digital TV OTA hassle free.
Different antenna adjustment may be required in some or many cases to achieve a signal lock on each and every station for which reception is desired or any given "set" of stations, Thus tuning to the known "remapped channel number" before a signal lock is acheived(including after a receiver's channel memory has been "wiped" by additional "full" channel scans with antenna at a "bad" orientation) on any particular station and trying to look at a "signal meter" for help in adjusting antenna properly is an exercise in futility and will not help.
You make the assumption that EVERY tuner wipes the VCT clean every scan. This is NOT true. Many tuners now (but not all) will allow an update scan as well as a full rescan for this very issue you seem to think is a deal breaker. So far it doesn't seem to be.
Of course, these things also need to be designed so a person can tune to or indivdually "scan" any RF channel number(2-69, now), including in cases when a PSIP VCT Major Channel # from a "different station" may be the same ch # as a RF channel # in the area ...
That is what the TSID is for so you CAN have multiple stations with different RF channels and the same virtual channel or vise versa. This does work and has worked on every STB I have owned since 2002. I do have two stations on the SAME RF channel with different virtual channels (one is channel 9 and the other is channel 10 and both are on RF channel 34) in markets on my fringe. I get both stations with not problem depending on the direction of the antenna and the station I click on. Again, the sky isn't falling. It works as advertised.
It's not that there is anything "wrong" with PSIP VCT and how they're doing it per A65/c + FCC rules, but in some cases, some (or many) OTA users will need a way to initially "tune"+individually scan in some stations using the RF channel # on their receivers, and they need to know what that is ....
Then viewers will do what they have always done since the start of broadcasting, as they are doing now when they have reception problems, they call the station and complain. I don't see that changing just because the TV signal isn't analog anymore.
Yeah, it's no big deal. They probably won't notice if a few stations don't show up on their TV after a auto channel scan. And if they do notice, some of them will be able to "figure it out", the others either just won't watch those stations(-- could be your station they aren't watching but who cares, right? No big deal ) or they can just get cable or satellite right? No big deal ....
Problem solved ....
Please read my above statement, again.
That Makes no sense whatsoever to me. If you're an OTA viewer who is having a problem with this, it's an issue for you, and it's an issue for the station you aren't watching(yeah, so maybe they don't care, that doesn't make it any less of an issue either), regardless of how many people in your area subscribe to cable or satellite ....
The truth is 15% of all viewers receive OTA nationwide. That is indisputable. That means that 1 out 6 people will have a STB. The rest will be on sat or cable. That makes perfect sense. Depending on their market, they may or may not have reception issues. If they have reception issues, I suspect they already do but because it is analog, they put up with it because there is something of a signal. Again, they will call the station in question if it becomes intolerable. They do now. At that point, it is up to the individual stations to work with the viewer. It isn't the receiver manufacturer or FCC to deal with specific cases if the receiver is functioning correctly and the viewer has a usable antenna system. If the station chooses to not help, then the station deserves what they get. It amazes me how people have come to think television is a God given right and everyone needs to bow down to them to help them. No where does it say in the Constitution or Bill of Rights that everyone is owed ALL television. The FCC is tasked to be sure the public has access to RF services. They are not tasked to GUARANTEE service. Big difference. That is the way it has always been since day one and that is the state of affairs now.
