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 == false) and the next is the same but active (b_current_next == true) then the service description list is empty and should be caught from the previous structure. This is a simulation to sdt.h

Function Documentation

dvbpsi_bat_bouquet_descriptor_add()

dvbpsi_descriptor_t * dvbpsi_bat_bouquet_descriptor_add	(	dvbpsi_bat_t *	p_bat,
