One of the big questions about all of this is whether or not the output of this system would actually be receivable on consumer ATSC tuners.
Well, it is conceivable that someone could tune this gear up on UHF TV channel 16, but it would be a shocking violation of FCC rules to do so. Nevertheless, if someone were to attempt something so foolish with a tenth of a milliwatt, and attempt to receive it with, say, a Samsung SIR-T451, they'd find that it actually would show a picture! Unfortunately, the audio wouldn't work, since it's MPEG 2 audio instead of Dolby AC3, but the picture would decode properly despite the lack of proper PSIP and despite the audio being the wrong codec.
For what that's worth.
