About BISS
The Basic Interoperable Scrambling System (BISS) works by inserting a 12-digit encrypted key into a multicast. BISS
documentation refers to these encryption keys as "session words".
The Session Word is inserted at the points of transmission and reception (in this case, the mediaHub HD 422).
A Conditonal Access Table (CAT) will be present in the multiplex, but this table will be empty, as no EMM stream will be
present.
Note: when encryption is enabled, Confidence Decode will not function.
