Detailed Description

Application interface for the EIT decoder and the EIT generator.

>

Author:

Christophe Massiot <massiot@via.ecp.fr> Application interface for the EIT decoder and the EIT generator. New decoded EIT 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 event information list is empty and should be caught from the previous structure.
