const unsigned dvbc_fec_table[]
converts from the descriptor's FEC into enum fe_code_rate, as defined by DVBv5 API.
const unsigned dvbc_modulation_table[]
converts from the descriptor's modulation into enum fe_modulation, as defined by DVBv5 API.
Provides a way to handle MPEG-TS descriptors found on Digital TV streams.
int dvb_desc_cable_delivery_init(struct dvb_v5_fe_parms *parms, const uint8_t *buf, struct dvb_desc *desc)
Initializes and parses the service location descriptor.
void dvb_desc_cable_delivery_print(struct dvb_v5_fe_parms *parms, const struct dvb_desc *desc)
Prints the content of the service location descriptor.
Structure containing the cable delivery system descriptor.
Linked list containing the several descriptors found on a MPEG-TS table.
Keeps data needed to handle the DVB frontend.
