siso_miso
const char * siso_miso[4]
converts from internal representation to string the SISO_MISO field of dvb_desc_t2_delivery:SISO_MISO...
dvbt2_interval
const uint32_t dvbt2_interval[]
converts from internal representation into enum fe_guard_interval, as defined at DVBv5 API.
dvbt2_bw
const unsigned dvbt2_bw[]
converts from internal representation into bandwidth in Hz
dvbt2_transmission_mode
const unsigned dvbt2_transmission_mode[]
converts from the descriptor's transmission mode into enum fe_transmit_mode, as defined by DVBv5 API.
