Verimatrix MultiCAS™/DVB


Unified Content Security for Hybrid Networks

Verimatrix MultiCAS/DVB is a key option within the Video Content Authority System (VCAS™) that integrates high performance third-party pay-TV head-end scrambler equipment with robust Verimatrix software-based content security. MultiCAS uses standardized DVB (Digital Video Broadcast) Simulcrypt to enable VCAS-compatible encryption of broadcast content concurrent with existing, traditional conditional access systems.

MultiCAS/DVB enables the creation of a unified content security system that can be used with a hybrid DVB-C/DVB-S/DVB-T broadcast and a VCAS-secured IPTV network. This hybrid network configuration enables operators to reap the benefits of low-cost, software-based security in their set-top boxes (STBs). In addition, it supplements their broadcast services with compelling video-on-demand (VOD) offerings employing the same robust content security. A key benefit for pay-TV operators is the ability to transition their existing subscribers to a more advanced security system supporting higher value services without disrupting existing revenue streams.

MultiCAS/DVB interfaces directly with third-party DVB Simulcrypt-compatible video, audio and data multiplexers, which perform the content encryption. MultiCAS/DVB generates VCAS-formatted entitlement control message (ECM) packets for insertion in the MPEG-2 Transport Stream to support client service decryption. The timing of key change intervals and other service parameters are managed directly through the multiplexer interface.
