Detailed Description

Contains the descriptors needed to scan the Service ID and other relevant info at a MPEG-TS Digital TV stream.

Parameters:

delivery_system Delivery system of the parsed MPEG-TS
entry struct dvb_entry pointer (see dvb-file.h)
pat PAT table descriptor pointer (table ID 0x00).
vct VCT table descriptor pointer (either table ID 0xc8, for TVCT or table ID 0xc9, for CVCT)
program PAT/PMT array associated programs found at MPEG-TS
num_program Number of program entries at program array.
nit NIT table descriptor pointer for table ID 0x40.
sdt SDT table descriptor pointer for table ID 0x42.
other_nits Contains an array of pointers to the other NIT extension tables identified by table ID 0x41.
num_other_nits Number of NIT tables at other_nits array.
other_sdts Contains an array of pointers to the other NIT extension tables identified by table ID 0x46.
num_other_sdts Number of NIT tables at other_sdts array.

Those descriptors are filled by the scan routines when the tables are found. Otherwise, they're NULL.

Note:

: Never alloc this struct yourself. This is meant to always be allocated via dvb_scan_alloc_handler_table() or via dvb_get_ts_tables().

Examples: dvbv5-scan.c.
