It will have to be possible to specify by humans, though many will be
machine generated.

Dan Zigmond's original "tv:" URL scheme was designed for this kind of use.
What's missing is the DNS-equivalent that takes a network or channel name
and looks up the "tuning" parameters.  (Tuning here may imply real tune to
a particular frequency, transponder or multiplex.)

The electronic program guides built into the kinds of devices we're
imagining usually have this kind of table, though the naming conventions
for channels and broadcasters haven't been standardized.
