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.
