The problem, as it pertains to Motorola STBs and some others, is how the software was originally written for the tuner.
When SW was written for the STBs there was an understood program channel paradigm established by the FCC. Some manufactures assumed these values would never, ever change. So, when they wrote SW for the STB, some of the manufactures utilized software and wrote it in such a manner the STB doesn't really deal with the information as it should; making it adaptable while having the ability to deal with new values.
Instead they took a short cut.
Program channel paradigms provide a key, in a sense, so the broadcast digital streams within the signal can be identified, much like DBS streams.
So, for example, station KXYZ broadcast a program with one video stream and three audio streams. Each audio stream is unique; 1.) English, 2.) Spanish, 3). Descriptive Services. The program channel paradigm facilitates how the station would like this information to be presented to the end viewer, i.e.: 10.1 video + English, video + Spanish, 10.3 video + descriptive services.
But when the FCC decided there were issues with Euro Sat standards and other issues that could present the potential for clashes, the FCC, in their infinite wisdom, decided to change the entire values of the schemes. If the software for STBs were written right in the first place, this wouldn't be an issue. But, alas, there are some of us who look for the easy way out. These are known as "schmucks." They are the ones who make life difficult by not doing what they should have done in the first place.
Anyway, Software for satellite STBs is simply downloadable over the system. Of course someone has to write the fix… As for standalone units that are designed only to capture OTA signals... you are going to have to contact the manufacturer or talk to where you purchased it and raise hell.
To reiterate here, most tuner software was written correctly in the first place. You probably will not see a problem, BUT you may not know for while or so because some of the stations do not have the ability to change program channel paradigms because it is hardwired into their encryption equipment, and they may not want to deal with the added expense at this time. Others have discovered users such those with the Motorola STBs and Samsung do not have the ability to deal with change; they have decided to operate the stations with old standards.
Either way, manufactures that chose to take the short cut will be require by the FCC to facilitate a software fix. Whether that takes form as a new STB, or a simple fix that has to be completed in a repair environment, in home, or mailed to somewhere, who knows?
All I can stay, if it were done the right way in the first place this wouldn't have become an issue and we wouldn't have ever been aware of the issue in the first place.
I hope this has been helpful. Good luck.
Postscript: Internal tuners will be subjected to the same challenges. Bank on the fact the manufacturer did it right in the first place. But, if you experience problems or are simply curious, be proactive and demand the manufacturer investigate and provide you with the results you seek.
