Setting Up the Conditional Access/Scrambling (Menu 4)

3.8.1

Introduction

Menu 4 allows the status and configuration of the Conditional Access (CA) module to be
checked. The structure and content of this group depends on the CA system. The available
CA options are as follows:
•
No Conditional Access
•
Basic Interoperable Scrambling System (BISS), Mode 1 and Mode E only.
•
Remote Authorisation System (RAS 1 and RAS 2)
•
TANDBERG DirectorV5
•
DVB Common Interface
•
Provider Lock
BISS (as specified in EBU Tech 3292 May 2002) is standard on all units. It is not possible to
have both DVB Common Interface and TANDBERG DirectorV5 on the same unit.
3.8.2

Remote Authorisation System (RAS) (Menu 4.1)

RAS has two levels of operation: FIXED KEY MODE and DSNG KEY MODE.
FIXED KEY MODE has a fixed control word to encrypt the data in the transport stream.
DSNG KEY MODE allows the user to specify the current session word so that it can be
matched with a live DSNG transmission. In a RAS 2 system, each receiver needs to be
enabled to decrypt the Transport Stream via the RAS II headend control system. Its main
functionality is:
•
Over-air addressing of Receivers for authorisation/de-authorisation to decrypt the
transmission.
•
Group operation for authorisation/de-authorisation.
•
Periodic control word changes during transmission.
Menu 4.1 allows fixed/DSNG selection and allows entry of the DSNG key.
3.8.3

TANDBERG Signal Protection (Menu 4.2)

The TT1260 can be enabled with TANDBERG Signal Protection, which is a non-smart card
based signal protection system. Contact TANDBERG Television sales desk for more details.
Menu 4.2 allows this protection system to be enabled/disabled.
3.8.4

DVB Common Interface (Menu 4.3)

There is one slot on the rear of the unit, to allow the insertion of a DVB common interface (CI)
conditional access module (CAM). This CAM module will host the Conditional Access (CA)
card for the CA system. The CAM and the CA card needs to be manufactured to host the
same CA system. Please contact TANDBERG Television sales desk for the recommended
CAM.
