CAT information from TS

[Arcane]

I am wondering how to get some more detailed Conditional Access Table

information from a Transport Stream. I can check for the PID and create

the CATable with the basic information from the DVB standard (CAT

length etc.), but where can I get further information about the content

of the CAT, depending on the broadcaster (information like encryption

used, key, etc)?

 

Anyone who can help me?
