I am a little puzzled as to why the second entry in your example is showing uncorrected errors and yet has a ber of 0.
Many (at least professional satellite modems) receivers calculate BER rather than actually measuring them, and the other way around. The theory is very clear here, and quite good in regards to real life performance. If one have the Carrier to Noise level, one can calculate the Eb/No value, which more or less directly translates to bit-error rate. It goes the other way around also, so if you have the bit-error rate you can calculate the CNR. (of course you have symbol-rate, fec and the other parameters for the carrier) This could cause the receiver to see the signal level as very good, and calculate a good BER, but still the actual Reed Solomon/FEC error correction will know that there where some errors there anyway because of poor syncronization. One should never assume that things are all good after only a few seconds. That could be it. Could also very well not be. It could also be that the BER and UNC reported are not for the same period of time. _______________________________________________ linux-dvb mailing list linux-dvb@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
