const uint32_t dvbt_interval[]
converts from internal representation into enum fe_guard_interval, as defined at DVBv5 API.
dvbt_hierarchy
const unsigned dvbt_hierarchy[]
converts from the descriptor's hierarchy into enum fe_hierarchy, as defined by DVBv5 API.
dvb_desc_terrestrial_delivery_init
int dvb_desc_terrestrial_delivery_init(struct dvb_v5_fe_parms *parms, const uint8_t *buf, struct dvb_desc *desc)
Initializes and parses the DVB-T terrestrial delivery system descriptor.
dvbt_bw
const unsigned dvbt_bw[]
converts from internal representation into bandwidth in Hz
dvbt_transmission_mode
const unsigned dvbt_transmission_mode[]
converts from the descriptor's transmission mode into enum fe_transmit_mode, as defined by DVBv5 API.
dvbt_code_rate
const unsigned dvbt_code_rate[]
converts from the descriptor's FEC into enum fe_code_rate, as defined by DVBv5 API.
