I'm pretty sure the audio on DTV is in-band digital embedded in the bitstream. (ATSC A/S2A) Gets the benefit of compression (however lossy) as well as the ability to encode 5.1 and other formats. Sad to say, I think the old out of band FM audio is going away with the analog video signals. (As inferior a standard as NTSC-M is to the HD formats, I have to say I'll miss it. It was fun pulling analog signals off of broadcast TV stations and dissecting them on the oscilloscope years ago ..) "This is an amazing honor. I want you to know that I spend so much time in the world that is spinning all the time, that to be in the no- spin zone actually gives me vertigo." -- Stephen Colbert during an interview on FOX News, The O'Reilly Factor _______________________________________________ http://www.mccmedia.com/mailman/listinfo/brin-l
