The bitfield signals the sync status of your frontend, see the 
fe_status_t definition in frontend.h for details. A completely working 
frontend has all bits set (status == 0x1f).

In reality you only have to check the FE_HAS_LOCK bit, this will get set 
if all other bits below are set.

signal means the signal strength in range 0x0000...0xffff, snr the 
signal-noise ratio, range is 0x0000...0xffff too.

ber is the bit error rate, unc the number of uncorrected errornous MPEG 
packets after the frontend's error correction.
