Astra 28.2E has S2 streams. In the UK, nearly all of Sky's HDTV streams are S2 - so its pretty obvious where they're heading with that. I will check if the S2 descriptors are used in those NITs. In the past we seem to have implemented API support for everything specced in the standards. For example DVB-T hierarchies: has anyone ever seen those used in a real system? Yet still we have support for them, so why should S2 be any different? And we can't predict unused features in DVBS2 from the lack of use of features in DVBT, since satellite broadcasting is entirely different from terrestrial broadcasting. _______________________________________________ linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
