The frontend is the fuzzy thing that makes electromagnetic signals in 
the air a MPEG2 transport stream. Even a network interface reading a DVB 
UDP stream from the net is a frontend.

Usually only RF sensitive components are located inside the tin box, the 
demodulator and the LNB supply circuitry is often placed side-by-side.
