4.12.14 BISS Options Enabled
Overview
BISS Mode 1 uses a fixed scrambling key, known as the Session Word, to
encrypt the transport stream. The same Session Word must be entered in
the Receivers and the Encoder to enable the transport stream to be
decrypted.
BISS-E adds an extra layer of security, as a unique key is required for
each Encoder and Receiver. This is known as the Encrypted Session Word.
Each Encoder and Receiver is assigned a unique BISS Injected ID, which
should not be made generally known, and which cannot be read from the
unit.
For a particular transmission a BISS Session Word is chosen, and then
encrypted, using each unit’s BISS Injected ID to produce an Encrypted
Session Word for each unit. This means that if an unauthorised person
obtains an Encrypted Session Word, it is useless unless they also know the
BISS Injected ID for the unit that the Encrypted Session Word was
intended.
Scramble Option
To access the Scramble option, press the Scramble softkey in the Mux
Menu
. This enables security scrambling of the Encoder transmission to be
switched on or off.
NOTE…
If the scrambling is switched between BISS Mode 1 and BISS-E, the session word, or the encrypted
session word must be re-entered.
