Hello, Suppose we know that several channels are transmitted on a given frequency by terrestrial antenna. However, we don't know if the signal is "encoded" (not sure this is the right term) in DVB-T or DVB-T2 modulation. Do we have to scan the frequency /twice/ first with DTV_DELIVERY_SYSTEM = SYS_DVBT then with DTV_DELIVERY_SYSTEM = SYS_DVBT2 ? Or is there some optimization where both modulations are handled in a single step? Or maybe it depends on the tuner driver?
It depends on the scan tool. Last time I used one te create my channel list I had to give a parameters to the command to skip encoded channels. That was over a year ago; I don't remeber any specifics. Jan Pieter.
