5.5.4.3 Basic Interoperable Scrambling System (BISS)
When the CE/SWO/BISS license is enabled the encoder can use the Basic
Interoperable Scrambling System (BISS) to scramble services in the outgoing
Transport Stream.
BISS Mode 1 operation uses a fixed value for the control word to scramble the
service in the Transport Stream from the encoder. To descramble the transmission,
the decoder needs to have the matching control word value.
BISS is configured by browsing to the service in the Transport Stream configuration
for the output. Each service can be encrypted using a different key, with up to 31
keys being available.
Once BISS has been enabled at a service level it is possible to select which
components in that service are scrambled using the key defined at the service level.
BISS Mode E operation additionally requires the entry of an Injected ID. This value
is associated with the unit rather than an individual service, so a single entry is
made by browsing to
Device Configuration > Advanced Setup , and selecting
Base Unit in the Advanced Video Processor Settings widget or by
Advanced/System/Base Unit/BISS Injected ID (14 hex digits) on the front panel.
To improve the security of the BISS encrypted stream, there are two modes
available (referred to as BISS security level) which are Normal BISS Encryption (the
original implementation) and Advanced BISS encryption. By default, Normal BISS
Encryption is enabled.
