Flexible Stream Encryption for IPTV Broadcast Services
The Verimatrix Real Time Encryption Server (RTES) is an optional component of the Video Content Authority System (VCAS™), which performs
all necessary stream formatting and video encryption for multi-channel broadcast support within IPTV deployments. In conjunction with the
Verimatrix Content Security Manager™ (CSM), which generates and distributes the necessary keys, RTES performs real-time encryption of
multicast IP transport streams containing compressed video in an MPEG-2 Transport Stream format, preserving the input bandwidth profile to
ensure consistent provisioning. Management information is inserted within each stream in entitlement control messages (ECMs), which are extracted
and used by the ViewRight STB and ViewRight PC Player client software to obtain the appropriate decryption key.
RTES interfaces with the IPTV middleware to manage channel-based subscriber entitlements. It also supports a system based on service classes,
which offers dynamic bouquet definition of content types on each channel, together with content rating and viewing limits. RTES offers clustered
operation to scale from one to hundreds of simultaneous channels, with automatic failover support to ensure continuity of service.
