marketplace, and provides a cost-effective mechanism to administer and operate a
multi-CAS environment.
The Cisco PCG performs real-time PowerKEY Entitlement Control Message (ECM) generation and distribution,
Simple Content Protection (SCP), and Simple Channel Control (SCC) ECM generation and distribution in support
of universal Digital Transport Adapters (uDTAs). The PCG operates within the DVB Simulcrypt headend reference
model, acting as an ECM Generator (ECMG) that uses the standard ECMG-to-Simulcrypt Synchronizer (SCS)
interface. An SCS can be configured to connect to multiple PCG virtual machines, providing fault tolerance through
the ECMG-to-SCS interface.
By using standard interfaces, the PCG can be integrated with headend equipment from multiple vendors. Using the
PCG allows you to run PowerKEY Conditional Access along with other conditional access systems in a mixed
environment. Both bulk- and edge-encrypted architectures are supported.
Product Overview
The Cisco PCG is a software product that runs on a virtual machine and has been qualified based on extensive
testing on a Cisco Unified Computing System
™
(Cisco UCS
®
) C220 M3 rack-mount server. The Explorer Controller
(EC) and Digital Transport Adapter Control System (DTACS) configure the gateway and manage sessions on it in
much the same way as on QAM devices. However, unlike the QAM devices, each PCG virtual machine can
provide ECM generation for 3000 PowerKEY digital broadcast streams or 3000 uDTA digital broadcast streams.
Multiple virtual machines per server are supported for larger stream counts on a single device, as shown in
Table 1.
