Detailed Description
Application interface for the PAT decoder and the PAT generator.
>
- Author:
- Arnaud de Bossoreille de Ribou <bozo@via.ecp.fr> Application interface for the PAT decoder and the PAT generator. New decoded PAT 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 program list is empty and should be caught from the previous structure.
