Overview of the user interface
The user interface is shown below:
The central window lists the units available in the database. Eeach of these may be selected for authorization. To change the selection status, double-click on the unit name. If the unit becomes selected, "Yes" will appear next to the name. If the unit becomes deselected, no text will be shown next to the name.
To select all units in the database, click on the "Authorize all". To remove authorizations from all units, click on "De-authorize all".
The currently applied session word is provided in a read-only text box. It is possible to cut and paste from this if the clear session word is required. Note that the clear session word is not shown in the output file for security reasons.
When this button is pressed, the selection of units from the main window have encrypted session words generated for them. These are output into a file (see later for how to set the output file name).
Once the encrypted session words have been generated, the user is offered the opportunity to view the file.

The output file format is as shown above. The date and time that the key data file was generated is shown on the first line, followed by the software version number.
The subsequent lines list all the units that were selected to have keys generated (any not selected are not shown). Against each unit is a 14-character hexadecimal number that is the uniquely encrypted session word for that unit.
Allows the user to specify the output file name that will be used for the generated key data. The file format is plain text to provide maximum ease of interchange.
Allows the user to enter a text string that will be displayed in the title bar of the application window.
This menu is used to add new units to the database. A text name is entered that is used in the main display window of the application and also for the output file name. The ID of the unit must be entered; this ID can be either 12 digits or 14 digits long.
If a 12-digit value is entered, this must be the electronic serial number of the unit, when this is used, the TANDBERG secure generation scheme is used for this unit.
For TANDBERG Television Alteia Plus units, see the section "Finding the unit number" for details.
If a 14-digit value is entered, this must be the USER1 ID (or 2,3,4). This is the interoperable mode and complies with the EBU BISS-E specification.
Allows the name or ID of the unit to be amended.
Allows a unit to be removed permanently from the database of units.
NOTE When deleted, there is no recovery mechanism, so suitable care should be taken when deleting units from the database.
Provides a new random session word value. This value is displayed in the "Current Session Word" box on the main menu. The session word is not applied until the "Generate Key Data File" key is pressed.
NOTE Once a new session word has been provided, there is no mechanism to revert to the previous session word.
Use with TANDBERG Television equipment
Alteia Plus
Version 2.8, or above, of Alteia Plus software is required for encrypted session word operation.
Finding the Unit Number
TANDBERG mode
On the Alteia Plus front panel, (menu 13) the serial number is shown in the format
ALT-91000012-A011-B31
The number "91000012" is the unique serial number for the unit. The Unit Number should be entered into the application by inserting four zero characters before the number, i.e. in the example, enter "000091000012".
On the Alteia Plus front panel, in menu 10, set the BISS MODE to MODE Eand the BISS-E ACTIVE ID to be "TTV".
EBU BISS-E standard mode
On the Alteia Plus front panel, in menu 10, enter a 14-digit hexadecimal value for BISS USER ID1 (or ID2). Select BISS MODE to MODE E and the BISS-E ACTIVE ID to be "USER 1" (or "USER 2").
On the application, enter the same value as set for the USER ID(1 or 2) to be the Unit Number.
Entering the encrypted session word value
Create the Encrypted Session Word file as described earlier.
On the Alteia Plus front panel, simply enter the value for this unit (as read from the line with the unit's name) into the "ESW" value in menu 10.
NOTE : On "saving" the ESW value, the display is replaced by a string of "*" characters. The entered ESW can no longer be viewed either locally, or via the remote control interface. This is by design. The same applies when entering an un-encrypted BISS mode 1 ESW.
