I live near Boston, and watched the games at home on a non-HD TV, fed via Comcast Digital Cable. I figured it was just a local problem — perhaps specific to my connection (my building's cable wiring is mid 80's, practically unshielded, and has caused reception problems). Or perhaps, my local Fox Affiliate, or it's feed to Comcast. Whatever — I just grinned and allowed the glory of the Red Sox to overshadow the annoying background noise.
Now, I'm hearing the same noise during a regular Fox NFL Broadcast — Giants vs. Cowboys. I'm starting to think there's something else at play here. A quick search on line has found others complaining about the "whine." No, nothing necessarily sinister (though I do welcome my new mind-control, broadcast overlords).
But as a former semi-pro audio engineer, I have to say there is no way this is could be making it past anyone with an ear — this must be intentional.
Anyone here on Slashdot hav an idea what its purpose is? Should I be fashioning the tin foil hat?
And please, if you haven't heard it, refrain from snideness. I've talked with a few, and while I can't discern a pattern, it's obvious some hear it and others do not.
