High Performance Broadcast Encryption for IPTV
Verimatrix MultiCAS/IP is a key option within the Video Content Authority System (VCAS™) that integrates third-party IPTV head-end scrambler equipment with robust Verimatrix software-based content security.
MultiCAS/IP uses standardized DVB (Digital Video Broadcast) Simulcrypt to enable VCAS-compatible encryption of multicast streams in an IPTV system. Integration of MultiCAS with commercial multiplexer and IP streamer equipment enables Advanced Encryption Standard (AES) scrambling of MPEG-2 and MPEG-4 multicast IP encapsulated content at high data rates across multiple service streams.
MultiCAS/IP interfaces directly with third-party DVB Simulcrypt-compatible video, audio and data multiplexers/streamers, which perform the content encryption. MultiCAS/IP 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.
MultiCAS/IP offers a high performance hardware alternative to the Verimatrix Real Time Encryption Server (RTES™) for broadcast content encryption when used in conjunction with third-party head-end scrambling equipment. In addition to the benefit of DVB Simulcrypt support, a MultiCAS-based configuration may provide additional choices in overall rack space usage, equipment redundancy and system management when configuring an IPTV head-end.
