The stuff on 1080p@60 caught my eye. A 1080i@30
base layer just seems wrong and already takes up the
entire channel. A 720p@60 base layer seems
much more appropriate. It would be ironic
if 1080p@60 drove the proliferation of
720p@60 for most ATSC viewers!

However, scalable encoding standards are not very
popular. Anyone ever seen any /real-time/ MPEG-2
Spatial@HL, SNR@HL or HP@HL decoders
or encoders? I haven't.

Plus, I would assume the enhancement layer is H.264.
That's a pretty different decoder (although not too
far fetched). The problem here is a chicken an egg
one. Without a decoder, the standard will not reach
critical mass.
