While a NIM is a complete frontend, a frontend need not be a NIM.
A NIM includes the tuner + demodulator(s) on its PCB (Hence, why they
are also known, but less commonly, as ITD; integrated tuner
demodulators). And this explains the "M" portion of NIM; being a
module, they are essentially a drop in frontend that can be integrated
into a device -- whether it be a STB, pc card ...
Examples of cards that don't use a NIM are the Fusion 3's and the pcHDTV
HD-3000 --- which use an analog frontend in conjunction with an external
digital demodulator. ...it is this combination that makes up the
complete frontends for the cards.
