AZ840 BISS Scrambler
BISS (Basic Interoperable Scrambling System) is the ultimate cost
effective solution for reliable and interoperable protection of
contribution and DSNG exchanges. The main advantages of BISS
are its simplicity and flexibility combined with free access to both
every manufacturer and user.
BISS is also a simple and efficient conditional access solution for
the primary distribution of programs between a hub and CATV,
Digital Terrestrial Television or mobile TV remote distribution
sites. In this case, BISS is the ideal solution to protect regional
broadcasting rights.
The AZ840 scrambles one program of the ASI transport stream
with a programmable Session Word. This Session Word remains
valid for the whole transmission period.
In Mode 1, the Session Word is programmed in the scrambler in
the clear.
In mode E, the session word itself is encrypted with a DES
algorithm before being programmed in the scrambler. The
Encrypted Session Word is encrypted with the Identifi er (ID) of
the scrambler. There are two possible Identifi ers: the buried ID
and the injected ID. The buried ID is hardcoded in the device and
the injected ID can also be programmed.
The scrambler automatically updates or adds the DVB SI tables,
adapts the output rate and restamps the PCR clock references in
the transport stream.
In its default configuration, The AZ840 has 2 ASI inputs which
can be selected either manually or automatically. One of the
Electrical ASI interface can be optionally replaced by an optical
interface.
Optionally, a high stability reference frequency can be
implemented.
