Conditional Access
D.1 What this Annex Describes
Figure D.1 (repeated in Figure D.10) illustrates a typical nCompass Control display
showing connections for a single ECMG/EMMG pair. This chapter describes the
procedure for configuring nCompass Control v5.0 (and above) with MX8400
multiplexers to support one or more conditional access systems.
Cautions!
It is assumed that the compression system is fully working before CA is configured.
Check that all software versions are correct and compatible.
Note: At the time of publication, nCompass Control supports Conax, Irdeto,
Cryptoworks, Nagra, Mediaguard, SIDSA, NDS and Viaccess Conditional
Access systems.

D.2 Overview
More than one Conditional Access scheme can be used simultaneously on the
same scrambled output. Each scheme is associated with a particular CA vendor.
Each CA scheme requires the use of an Entitlement Control Message (ECM)
generator and an Entitlement Management Message (EMM) generator.
