Design and development of a new POD module chip-set based on the OpenCable specification

In this paper, we have designed a hardware architecture of the OpenCable set-top and the point of deployment (POD) module. The designed POD module has an embedded 32-bit RISC microprocessor which manages applications such as MPEG-2 filter, descrambler, and DES. We have proposed the OpenCable reference model and implemented a conditional access system (CAS). We have tested this system using a prototype and have obtained satisfactory simulation results.
