Overview

The BNP supports the DVB-CA Common Scrambling Algorithm (CSA) and DVB SimulCrypt protocols
(ETSI TS 103 197 V1.5.1) for Conditional Access System (CAS) which interfaces with DVB systems. This
allows for encryption of MPEG-2 and H.264 programs in both SD and HD resolutions. The embedded
SimulCrypt Engine is a low cost, high density, scalable encryption and management control
implementation that is fully DVB-CA compliant. The BNP provides two 10/100 Ethernet management
ports, allowing one of these port to be dedicated to the DVB-CA network. For an example topolgoy,
see Figure 6, "BNP in a DVB-CA Network," on page 17.
The DVB-CA encryption feature includes the following functions:
SimulCrypt Synchronizer (SCS).
•
Control Word Generation (CWG).
•
Common Scrambling Algorithm (CSA).
•
ECM / EMM insertion.
•
CA-related PSI / SI generation and insertion.
•
BNP's proprietary SimulCrypt engine interfaces with the following devices:
Entitlement Control Message Generator (ECMG).
•
Entitlement Management Message Generator (EMMG).
•
Optional external Event Information Scheduler (EIS)
•
1. The BNP may be configured to use an external EIS server or the internal EIS server provided by the BNP
software.
