Operating the Equipment Locally
Reference Guide: RX1290 H.264 Contribution Receiver
Page 3-13
ST.RE.E10228.1
3.8.2 Basic Interoperable Scrambling System (BISS) (Menu 4.4)
BISS Mode 1 is similar to RAS in that it uses a fixed control word to encrypt the data in the
transport stream. Unlike RAS, the scrambling algorithm is non-proprietary, using the DVB
Common Scrambling Algorithm to allow interoperability with other manufacturers’
encoding/scrambling equipment.
3.8.3 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 is used for fixed head-end systems. 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.
3.8.4 TANDBERG v5 Director (Menu 4.3)
Director functionality includes Conditional Access, over-air software download and over-air
control.
No specific set-up is required at the Contribution Receiver for the Conditional Access or
software download. For over-air control (NCP) see Chapter 4, Operating the Equipment
Remotely.
3.8.5 DVB Common Interface (Menu 4.2)
There is a single slot on the Contribution Receiver pack panel to allow the insertion of a DVB
Common Interface (CI) Conditional Access module (CAM) and related conditional access
card.
Other than the insertion of the CAM and Access card, no specific set-up is required at the
Contribution Receiver for the DVB Conditional Access.
3.9 Setting Up the Transport Stream Output (Menu 5)
3.9.1 Set-up Procedure
Use Table 3.18 to step through the Transport Stream Output set-up procedure using Menu 5.
This allows the Transport Stream for the current Service to be output on the ASI output
connectors.
Table 3.18: Setting Up the Transport Stream Output (TSO)
Step Action Result
1 Go to Menu 5 to enter the TRANSPORT
STREAM OUTPUT setting.
Press Edit then select one of the following:
POST INPUT (i.e. as input Transport Stream);
POST TS DESCRAMBLE (i.e. post TTV
Signal Protection and RAS descrambling);
POST ES DESCRAMBLE (i.e. post TTV,
RAS, Common Interface, BISS, DIRECTOR
descrambling).
The Transport Stream Output will be formatted according to the
choice made.
