3.7.26 How to Set Up BISS Encryption for Services
When the AVP/SWO/BISS license is enabled as part of the AVP/SWO/MEZZ/BASIC
package, the encoder uses Basic Interoperable Scrambling System (BISS) to
scramble services in the outgoing Transport Stream. Both BISS Mode-1 and BISS
Mode-E are supported.
3.7.26.1 BISS Security
To provide the option of additional security for the BISS encrypted stream, there are
two security levels available: normal BISS encryption (the original implementation)
and Advanced BISS encryption (new, higher security). By default, normal BISS
Encryption security level is enabled.
If the higher security level is required this can be configured from the GUI by
browsing to Device Configuration > Advanced Setup > Base Unit.
