A
ccess: Several providers send their programmes encoded. In order to de-
code this programmes on the receiver side, a Conditional Access Card (hardware) of
the provider is needed. Together with the identification of the data in the MPEG-signal,
if the receiver supports this function, the signal can be decoded.
Smart-Card
The smart card is supplied to the program receiver after obtaining the licence (Pay-TV)
or another valid authorization. On the smart card customer-specific data is stored. The
CA-module includes a smart-card reader. The releasing of decoding of programs hap-
pens via the digital data stream.
