dvbs_modulation
const unsigned dvbs_modulation[]
converts from the descriptor's modulation into enum fe_modulation, as defined by DVBv5 API.
dvbs_dvbc_dvbs_freq_inner
const unsigned dvbs_dvbc_dvbs_freq_inner[]
converts from the descriptor's FEC into enum fe_code_rate, as defined by DVBv5 API.
dvbs_polarization
const unsigned dvbs_polarization[]
converts from the descriptor's polarization into enum dvb_sat_polarization, as defined at dvb-v5-std....
dvbs_rolloff
const unsigned dvbs_rolloff[]
converts from the descriptor's rolloff into enum fe_rolloff, as defined by DVBv5 API.
