The Core of the Verimatrix Video Content Authority System
The Verimatrix Content Security Manager (CSM) is the core component of the most advanced software-based content security system available – the Verimatrix Video Content Authority System (VCAS™). CSM enables and supports all features and options within a VCAS secured pay-TV system, including broadcast/multicast only, video-on-demand (VOD) only, or hybrid broadcast and VOD network deployments with secure, real-time key distribution for the full spectrum of content services.
CSM is also equipped to support deployment of advanced interactive pay-TV features, such as digital video recorders (DVRs) and network DVRs
(nDVR), in conjunction with other head-end components. CSM acts as the root Certificate Authority in a PKI hierarchy. It uses X.509 certificates
to validate and authorize all content protection communication within the pay-TV network, including messaging between VCAS sub-system
components as well as between the head-end system and authenticated subscriber receivers.
Implementations of CSM can be cost-effectively scaled to meet any size of operator deployment by distributing system components across clusters
of servers and database engines, using load balancing and fail-over support for each mission critical component. Interfaces to middleware packages
are flexible and lightweight, with both “push” and “pull” models for access to subscriber entitlement data.
