We propose the merging of the OpenCable reference model with the smart card interface defined by ISO/IEC 7816-3 and have implemented a new conditional access system (CAS) using this interface along with a Personal Computer Memory Card International Association (PCMCIA) interface. In addition, we have also designed the hardware architecture of the point-of-deployment (POD) security module, designed using the Verilog HDL, using the above two interfaces. The designed POD security module has an embedded 32-bit reduced instruction set computing (RISC) microprocessor that manages applications, such as an MPEG-2 filter, descrambler, and data encryption standard (DES).
