The Clarke Belt is a dedicated satellite orbit in which
satellites remain in a fixed position relative to the Earth's
surface.
Both names are used for these modules. These modules are
PCMCIA cards with a slot in which you can insert a smart
card.
A DVB standard which defines the software and hardware
requirements for condition access systems.
