CONDITIONAL ACCESS SYSTEM (CAS)

Black Swan's Conditional Access System safeguards Pay-TV revenues through DVB-CSA3 and AES-128 encryption. Built to prevent signal piracy, card sharing, and unauthorized redistribution, our CAS secures content across card-based set-top boxes and cardless software client architectures.

Core System Capabilities

DVB-CSA3 Encryption

Advanced military-grade scrambling preventing stream decryption hacks.

Dynamic Fingerprinting

Injects invisible or visual subscriber ID watermarks onto TV screens to catch illegal restreamers.

Simulcrypt Compliant

Supports DVB Simulcrypt standard to run multiple CAS vendors on one stream.

Cardless & Smartcard Options

Deploy legacy smartcard systems or modern chip-set paired cardless software CAS.

Protecting Broadcast Revenue Against Signal Piracy

Signal piracy costs pay-TV operators millions in lost subscription revenue every year. Black Swan's Conditional Access System (CAS) provides robust DVB-compliant encryption and real-time subscriber authorization controls.

Forensic Fingerprinting & Anti-Restreaming Defense

When pirates attempt to capture HDMI feeds from set-top boxes for illegal IPTV restreaming, our CAS dynamically overlays unique covert subscriber ID numbers onto the screen, allowing operators to identify and disable the offending account within minutes.

DVB Simulcrypt Architecture

Our CAS hardware scramblers strictly follow DVB Simulcrypt guidelines, enabling cable operators to run multiple CAS vendors side by side without duplicating video bandwidth streams.

Frequently Asked Engineering Questions

Q: Can this system protect high-definition 4K channels?

Yes. DVB-CSA3 encryption and chip-set pairing ensure 4K UHD content meets strict Hollywood studio security guidelines.

Q: What is the difference between Card-Based and Cardless CAS?

Card-Based CAS uses physical ISO smartcards inserted into STBs, while Cardless CAS relies on secure hardware chipsets inside the set-top box processor, reducing logistics costs.
