I can't see any reason not to provide for the second mapping also,
even if there will be a larger number of mapping tables on a global
basis. For example, in the city where I live I'd guess there are less
than 5 usable such mapping tables, and I'd much prefer to chose
between the 5 than to manually locate and name every program. Not to
mention that whenver my cable-provider decides to change something, I
can probably get a new mapping table from someone else. And even if I
do need to manually make a mapping table, I'd prefer it to be done
such that it is consitently available from all my TV
applications. ..Or am I missing your point here?

This is in agreement with the comments I made earlier that radios want
to map directly from program name to frequency.

Like I said, this can be solved by introducing "special"
frequency-names, where the real frequency is inferred from the name
itself (like the mapping "129 MHz" -> 129000000).


What do you think?
