Do any
HDTV --> NTSC
or
HDTV --> PAL
consumer receivers use MUSE (Multiple Nyquest Subsampling) to convert HD
to
Analogue resolution?
It would seem to me to be an inexpensive solution, and it would only
require
minor modifications of NHK Research chipsets to do so.
I have no idea what approach current converters are using, but it clearly
is
not Phase Correlation (so called PHc).
MUSE (in silicon terms) can be done at 1/10th the cost of Phase
Correlation,
and gives a far better (and more consistent) output than any line
manipulation tricks.
PS:
I wonder how many HDTV sets are Y2038 proof?
If there is any argument for using 64 bit Unix Time in this kind of
consumer
device, they need to be made now.
