So a very short > error will cause unc, but no higher BER. You may not see a higher BER, because the corrupted signal doesn't hit the BER measuring period. Femon asks every 1 second for new values. The UNC counting interval is this 1 second, but the BER measuring interval is shorter (50..200ms). For a stv0297, it is 150ms for QAM256 modulation and 200ms for QAM64. The real measuring interval for the BER is a fixed number of bits. -Hartmut _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
