Detailed Description

Application interface for the SDT decoder and the SDT generator.

>

Author:
Johan Bilien <jobi@via.ecp.fr> Application interface for the SDT decoder and the SDT generator. New decoded SDT are sent by callback to the application. If a table wasn't active (b_current_next == 0) and the next is the same but active (b_current_next == 1) then the service description list is empty and should be caught from the previous structure.

Define Documentation

#define dvbpsi_DeleteSDT ( p_sdt   ) 
Value:
do {                                                                    \
  dvbpsi_EmptySDT(p_sdt);                                               \
  free(p_sdt);                                                          \
} while(0);

Clean and free a dvbpsi_sdt_t structure.

Parameters:
p_sdt pointer to the SDT structure
Returns:
nothing.
#define dvbpsi_NewSDT ( p_sdt,
i_ts_id,
