C.0 Conditional Access Overview
Conditional access (CA) is a method for securing and scrambling transmission streams so that
only those decoders which are authorized to do so can receive the transmitted streams.
The SE4000 provides two methods for conditional access:
•
BISS – an industry-standard scheme which allows full conditional access operability
between various vendor’s DSNG equipment
•
PGCA – a Tiernan proprietary scheme providing conditional access within the Tiernan
family of products
C.1 BISS Overview
BISS, the Basic Interoperable Scrambling System, is an industry-standard, conditional access
scheme used to secure and scramble DSNG broadcasts while allowing full inter-operability
between various vendor’s DSNG equipment.
The SE4000 currently supports BISS Mode 0, 1, and E scrambling. With Mode 1, all components
of the transmission stream are scrambled by a fixed control word (CW). The control word must be
manually entered into the encoder and decoder for BISS operations.
C.2 High-Level BISS Procedure
BISS is managed and enabled at an individual service level. To configure the SE4000 for BISS
operations, follow these steps:
1.
Select the service for BISS conditional access.
2.
Enable BISS for that service.
3.
Enter the Scramble key.
C.3 Configuring BISS from the Front Panel
To configure the SE4000 for BISS operations, follow these steps:
