ABSTRACT:
According to one embodiment of the invention, a configurable CableCARD adaptable for use by multiple conditional access (CA) providers. CableCARD comprises core logic configured to descramble incoming scrambled content, a first CA logic block and a second CA logic block. Connected to the core logic, the first CA logic block uses a first CA function associated with a first CA provider. The second CA logic block is also connected to the core logic. The second CA logic block uses a second CA function associated with a second CA provider. Where the incoming content is scrambled according to the second CA function, the connection between the first CA logic block and the core logic is disabled.
