Thinking of worthy patentable devices
I wonder if anyone makes this sort of truly unirversal r/c for those
annoying situations of one or more key functions missing from the one you
want.

2 stages
1/ Just the recognition code going through all possible permutations
to find the basic power on/off repeated sequence.
Lock that down in memory

you would die waiting if it went through all possible codes.

2/ and then after that specific code, all operational bit sequences until
that does a function on the TV etc and lock that to a button on the r/c.

that bit is somewhat easier... once the baudrate, carrier frequency,
and encoding scheme are known all that remains is to experiment with
hundereds of possible symbols.
