I can't tell exactly what 4.0.19 does. May be I'm wrong, but I suppose, patch 4.0.19 for B40 has so big size, because most likely it resolves the same issues as patch 3.0.20 for A30: Here, in Russia, TV broadcasters actively using Multi PLP in DVB-T2 transmissions. In some cities, were problems with switching to PLP#1 or PLP#2 without A30 3.0.20 patch. (Different cities in different time zones lead to a separate mux transport streams for them.) What I can tell exactly, is that A30 3.0.20 contains an update for Si2168, which allows demodulator to lock PLP#2 with an "old" type OFDM frame encoding. Also it speed up locking for low bitrates PLP. In short: it fixes a serious issue with Multi PLP locking. > I assume the info originates from > http://beholder.ru/bb/viewtopic.php?f=11&t=14101 , but I don't understand > Russian at all. Yes, you are right. Best regards.
