In some countries, thest andards may not be
av ailable, or may not be available in all areas.
A CI+ module (Common In terface Module),
which is not included in the scope of deliver y,is
used todecrypt HD prog rammes according to
th e CI+ standard. In some countries, an addi‐
tional smart card is required, which is inse rted
into the CI+ module (see the manufacturer's
