Introduction

Conditional Access and Scrambling

The transport stream received by the IRD may be encrypted. The CA
system is used to decrypt the required components of the transport
stream so that they can be decoded.
The following Conditional Access and Scrambling options are available for
the TT1260 range of Satellite Receivers and Decoders:
·
No Conditional Access
·
Basic Interoperable Scrambling System, BISS Mode 1 and Mode E only.
·
TANDBERG Director
·
Remote Authorisation System (RAS) 1 and 2
·
Signal Protection
·
DVB Common Interface
BISS (as specified in EBU Tech 3292 May 2002) is standard on all
Receivers/Decoders.
The different CA options can be combined, for instance:
·
TANDBERG Director, RAS and BISS (however, streams with mixed CA
are not supported)
However, it is not possible to have both DVB Common Interface and
TANDBERG Director on the same unit.
When the CA system uses a smart card or Common Interface Module,
access by the user is via the back panel of the IRD.

The Satellite Receiver

1.3.1

Typical Satellite System

The TT1260 Satellite Receiver is a component of the MPEG-2/DVB
compliant range of TANDBERG Television equipment. It is designed for use
by broadcasters and distributors of video, audio and data services over
satellite.
1.3.2

Input Connections

The Satellite Receiver interfaces directly to Low-Noise Block (LNB) and
accepts an intermediate frequency (IF) input in the band 950 - 2150 MHz
(L-band) for operation in the specified symbol-rate range (see Annex B,
Technical Specification). The unit can provide dc power and polarisation
switching to the LNB.
