The ATSC has codified E-VSB in it's specifications, but the FCC has yet to
adopt those specifications into the rules.
FWIW, all Zenith VSB demodulator chips and receivers ever sold have the
ability to receive and decode 16-VSB, 4T-VSB, and 2T-VSB in addition to the
usual 8T-VSB.
That is not the same as E-VSB or A-VSB, but 4T and 2T was once suggested by
Zenith as alternate transmission modes that lowered the C/N requirements
even more, but were never adopted by the ATSC. AFAIK LG/Zenith chipsets
still contain these legacy modulation modes.
