dvbc_fec_table
const unsigned dvbc_fec_table[]
converts from the descriptor's FEC into enum fe_code_rate, as defined by DVBv5 API.
dvbc_modulation_table
const unsigned dvbc_modulation_table[]
converts from the descriptor's modulation into enum fe_modulation, as defined by DVBv5 API.
descriptors.h
Provides a way to handle MPEG-TS descriptors found on Digital TV streams.
dvb_desc_cable_delivery_init
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.
dvb_desc_cable_delivery_print
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.
