CTN-9120 M-Card Processor
The CTN-9120 provides the hardware interface between the newest multi-stream CableCARD, the M-Card, and middleware stacks, demodulators, and MPEG decoders. The controller implements OpenCable CableCARD Interface and Copy Protection Specifications. The robust architecture of the CTN-9120 allows seamless integration of software on any system over a PCI bus and includes two embedded processors for secure processing of middleware stacks and Digital Rights Management.
