Detailed Description

Application interface for the PMT decoder and the PMT generator.

>

Author:
Arnaud de Bossoreille de Ribou <bozo@via.ecp.fr>
Application interface for the PMT decoder and the PMT generator. New decoded PMT tables 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 two lists are empty and should be caught from the previous structure.
