Detailed Description

Application interface for the BAT decoder.

Author

Zhu zhenglu zhuzl.nosp@m.u@gm.nosp@m.ail.c.nosp@m.om Application interface for the BAT decoder. New decoded BAT 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. This is a simulation to sdt.h

Macro Definition Documentation

#define dvbpsi_DeleteBAT

(

p_bat

)

Value:

do {                                                                    \

  free(p_bat);                                                          \
} while(0);

Clean and free a dvbpsi_bat_t structure.

Parameters

p_bat

pointer to the BAT structure

Returns

nothing.

#define dvbpsi_NewBAT	(		p_bat,
			i_bouquet_id,
			i_version,
			b_current_next
	)

Value:

do {                                                                    \

    dvbpsi_InitBAT(p_bat, i_bouquet_id, i_version, b_current_next); \
} while(0);

Allocate and initialize a new dvbpsi_bat_t structure.

Parameters

p_bat	pointer to the BAT structure
i_bouquet_id	bouquet ID
i_version	BAT version
b_current_next	current next indicator
i_network_id	original network id

Returns

nothing.
