The only way I see of you getting something narrow in bandwidth to
transmit video luma would be to take it, and create a digital system
that has a very large number of discrete states, so large that the
lines between them seem to blur, and transmit it at a very high
frequency (or more, maybe even an ultra high frequency), with a large
number of bits per symbol (8 seems like a good number) but a very high
temporal resolution.  You could even modulate a color subcarrier on
and add in chroma information on two axis, lets call them I and Q.
This will create a situation where the receiver will be receiving the
data with interference, but since you are only sending a small amount
of data at each temporal interval, any interference's effect within a
decent area will be negligible and the viewer's eye's will compensate.
On second thought, analog video is so much simpler (and exactly the
same, except it lacks discrete levels).

A confused Eric, wondering why you're trying to do this....
