3.3 Basic Interoperable Scrambling System - BISS
(M2/EDCOM2/BISS)
With the appropriate configuration, the Encoder can use the Basic
Interoperable Scrambling System (BISS) to scramble the outgoing
transport stream. This system has been developed by the European
Broadcasting Union (EBU) as an open scrambling system.
BISS has three main levels of operation: Mode 1, Mode 2 and Mode 3.
Mode 0 corresponds to no scrambling.
NOTE…
Only Modes 0 and 1 are available at this release (Build version 2.0.0). Modes 2 and 3 are not
supported.
BISS Mode 1 operation uses a fixed value for the control word to scramble
the services in the transport stream from the Encoder. To descramble the
transmission, the Decoder needs to have the matching control word value.
The BISS Module (M2/EDCOM2/BISS) comprises Assembly S12284 and
Card S11484.
NOTES…
1. This option module is installed as a daughter card to the Base Board, with no external
connectors and does not use an option slot.
2. The BISS software must also be enabled in the Encoder (see Customer Services).
BISS scrambling (when fitted) is enabled and controlled via the Setup/Mux
Menu (see Chapter 4, Operating the Equipment Locally, Section 4.12.10).
