Perhaps "front end" should be better defined. I
mean tuner and MPEG decoder. After trellis and
RS decoding, the signal sent to the MPEG decoder
can be decimated, in principle, to be compatible
with MP@ML.
May years ago now, I saw estimates that a
decimating STB could be sold for "as little as"
$250, compared with the HD price of around $500.
Seems kind of funny now, though.
