I do not know any of the engineers in the Wilmington area. I grew up in Fayetteville and lived in Lumberton in the early to mid 80's, but I have no idea now. I can give you some info that you can use to determine how you want to proceed on that idea. My uninformed opinion would be to give them some time to get it all figured out before you start raising cane. Calling them and telling them you have suggestions may not go over well. You might call and suggest that you would like to be a part of any OTA testing they might do. Let them stay in charge and you just offer reception reports, not fixes.
Stations in smaller markets like Wilmington do not have large staffs, much less large Engineering staffs. Not only is DTV a financial drain on capital and operating funds, but on manpower as well. The DTV transmitter is not high on very many commercial stations engineers mind and as long as it is putting out power and there is some kind of signal on the air, most are happy. They take this attitude for two reasons, one, there is no real audience yet for the DTV side (particularly in small markets) and two, there are things to do on the analog side, the side that is paying the electric bill to run that DTV transmitter, the side that is buying that DTV equipment and most importantly, the side that is paying salaries. Add to the fact that DTV is all new technology, and most if not all smaller market engineers are not as well versed in it and the learning curve is a 90 degree wall. When we went on with DTV April 2002, I spent the first 6 months trying to figure out what I had and how I could keep it from crashing all the time. I spent the next six months trying to get the transmitter stable enough for people to watch it; all 50 of the them. I have spent the next six months trying to improve the quality of the signal and now just as I gotten 480p down, I am now learning about 720p and how it works and doesn't work compared to what I already know with 480p. I have the benefit of a large corporation behind me for any questions or problems I might have. Most of the smaller market stations are not owned by mega billion dollar companies and they have it much tougher to get problems or questions answered. The cliff effect takes on a whole new meaning in this vain.
But don't feel sorry for us. We adapt fairly fast. Just think of DTV in this stage as a backstage look into broadcasting. You are seeing things that the rest of the viewers will never see since by the time the mainstream viewers come on line, these problems will be solved and it will all being boring, just like analog is now. But remember, in the early days of TV, analogs equivalent of the DTV problems were watched by early adapters then. How often do you see Technical Difficulty slides these days. Hardly ever, but just 20 years ago, it was common.
Can you clip a video signal similar to audio? What would the picture look like? Do you think the encoder needs adjustment, or is it the source signal? If the analog looks good, but the DT looks bad, what's to blame?
Yes you can. Either do a screen capture if you have a DTV tuner card in your computer or you can take a picture of your screen with either a 35mm camera or digital camera. As far a DTV PQ, it could be several things and yes it could be the encoder is not set to a large enough bitrate or the analog to digital converter has problems or needs a tweak, or if the transmitter is not tuned correctly, it could cause pixalization or loss of picture all together.
Also, tried to get to your website listed in your profile--can't connect. Got any stuff that our corporate firewall won't pass?
Shouldn't be hanging at a gateway. It just asks for on site cookies to keep up with your security level. I do not do tracking at all. I am opposed to site tracking. I run the NCHDTV.com site only. The Triad site is run by another person and I have no say over that site.
