Overview
- BNP Deployment Architecture
DVB Conditional Access (DVB-CA) Encryption
Applicable Platform:
BNP 3xr
The BNP 3xr supports the DVB-CA common scrambling algorithm (CSA) for encryption of MPEG-2 and
H.264 programs. The embedded SimulCrypt Engine is a low cost, high density, scalable encryption and
management control implementation that is fully DVB-CA compliant.
The DVB-CA encryption feature includes the following functionalities:
•
SimulCrypt Synchronization (SCS).
•
Control Word Generation (CWG).
•
Common Scrambling Algorithm (CSA).
•
ECM / EMM insertion.
•
CA-related PSI / SI generation and insertion.
•
SimulCrypt EIS Lite GUI configuration and management.
RGB’s SimulCrypt engine interfaces with the following external devices:
•
Event Information Scheduler (EIS).
•
Entitlement Control Message Generator (ECMG).
•
Entitlement Management Message Generator (EMMG).

BNP Deployment Architecture
The BNP’s modular and programmable platform is designed to provide operators with full processing
scalability to meet their specific processing requirements. The program density of the BNP is software-
configurable and upgradeable, allowing operators to start at lower densities and upgrade to the full
hardware capacity through software licenses as their stream densities and network needs grow.
