Common Interface - (CI) -
Describes
hardware
and software architecture for Conditional
Access Systems
where the
generic "host" set-top
box is not dedicated to one particular
encryption
system. Consumers use detachable hardware which allows them to receive
encrypted services they pay subscription fee(s) for. The interface
between
the host set-top box (or equivalent) and the CI hardware is
standardized
(PCMCIA-Interface)
so that the same set-top box (or equivalent) can be used to handle a
variety of
encryption
systems. Also see https://en.wikipedia.org/wiki/Common_Interface.
