Question for Big Al

Don,
ATSC A/85 accounts for that. The K weighting factor is looking at average loudness averaged over a period of time. The good news is that it really works. The bad news is that the originator is responsible to set it correctly while any broadcaster is tasked with maintaining the standard even if the originator didn't do their job. We get the fine, they may or may not. Satellite and cable operators must comply as well. This can be a big deal for them and the few that I have talked to are very concerned.

What type of TV do you have? I thought there was a particular model of TV that had a method for identifying, and controlling volume of commercials.

Yeah, well, my experience was with NTSC, now obsolete over-the-air. Stay current or become obsolete - a good lesson for today's engineers (and engineers-to-be).

Hey, if I remember correctly, it was you (Al) that killed Analog!

Don,
That reminds me... That transmitter was a LARCAN manufactured in Mississauga, Ontario, just outside of Toronto. They were in the industrial park just to the west of the airport. Larcan was shut down by it's Chinese parent company, with no warning, in July of this year. The Chinese company had acquired controlling interest in 2009. The transmitter shown is still on the air. With the impending resuffle of channels mandated by the FCC, they will likely be relocated as will our Channel 47 transmitter that is just over 10 years old. Whether we will be able to continue to use it or not remains to be seen. I just read an article from a wireless microphone manufacturer that is calling for a investigation of the FCC rule making which plans to take away the wireless mic channels that are given clear use in current FCC band plan.
