Hi, So you mean that the "ber" occurence will not related to the captured TS quality ? I would like to clarify my question, which is as the status screen dump is shown below, the captured TS quality is so bad, some flahsing squares will appear on some frames randomly at some instance (just seems the captured TS packets are corruppted and missing). So I suspect is this due to the bad performance of TDA10046 + TD1316 ? Thanks for answering.

Should the "ber" field is zero for a > good signal? No, BER is the bit error rate before the error correction. Even a strong signal may have a few bit errors if single carriers are disturbed. But the error correction for DVB-T is very strong. BER can be >0x8000 without uncorrectable errors appearing. -- Georg Acher, acher@xxxxxxxxx http://www.lrr.in.tum.de/~acher "Oh no, not again !"
