Session Word.
BISS-E
All components are scrambled by a fixed control word, derived from an
Encrypted Session Word.
Session Word:
A Session Word is the 48-bit code
used to encrypt and decrypt the
transport stream.
The sender and receiver(s) of the transmission share the Session Word, so that only the intended parties
receive the transmission. The same Session Word must be used at the receive end.
If the Session Words are the same, then the IRDs are able to decrypt the broadcast. If the Session
Words are different, the broadcast is not received.
CAUTION…
Take precautions to avoid general knowledge of the Session Word.
SNG Key (RAS 1):
Encoder output is scrambled. Scrambling key used is entered using the SNG
Key (RAS1) option.
This option enables the scrambling key used in SNG Key scrambling mode to
be set (see the Scramble option). The same scrambling code must be used at
the receive end to unscramble the transmission.
Enter up to seven digits using the keypad. If less then seven digits are entered,
they are prefixed with 0’s (zero) to give a seven digit code.
