3.3.2.5.8
Odd/Even-1
This mode is not part of the BISS standard but has been successfully interoperated with other
manufacturers who have similar variants. Each MPEG packet has a field in the header which
indicates if it is in the clear, encrypted using an ODD key or encrypted using an even key. While
BISS only uses the one key, this mode allows two independent keys. The advantage of this mode
is that it allows keys to be programmed offline while using the other key for decryption. Both the
odd and the even session word will require a 12 digit hex value. The even key is the same key as
that used for BISS-1.
3.3.2.5.9
Odd/Even-E
Odd/Even-E also uses the odd and even keys in the same way as Odd/Even-1 mode but each
key is encrypted using the same Injected Id. The Injected Id will require a 14 digit hex value and
the ESWs will both require 16 digit hex values. The even key is the same key as used for BISS-E.
3.3.2.5.10
User-1
This enables a specific user mode where specific PIDs are decrypted. The SI information is not
altered so this mode is not BISS compliant. The actual PIDs to be decrypted are specified only on
the command line. A 12 digit hex value is required for the session word. The even key is the same
key as used for BISS-1.
This mode is used to guarantee that the decrypted transport stream will match the original.
3.3.2.5.11
User-E
This is identical to the User-1 mode except a 16 digit hex value is required for the ESW and a 14
digit hex value is required for the injected ID. The even key is the same key as used for BISS-E.
3.3.2.5.12
Processing
This will be set for Encode for encryption and decode for decryption. This setting will depend
upon supported feature keys.
3.3.2.5.13
BISS Insertion Period
This sets the frequency that the Program Association Table (PAT), Programme Map Table (PMT)
and Conditional Access Table (CAT) will be inserted into the stream. The default is 200 ms and this
value should be suitable in most circumstances.
3.3.2.5.14
BISS Active Key
When the BISS Mode is either Mode-E or ODD/EVEN-E or User-E then the BISS Active Key can be
selected. This determines which key shall be used.

Select
The Keys are entered using a hexadecimal notation. Use the left and right arrows to select the
required character then use the down arrow to select the character. This can be deleted using
the up arrow. When the Key or Id is complete then press ENTER.
