Scs Overview - Motorola APEX1000 Installation And Operation Manual

SCS Overview

SCS functionality is the main component within the SimulCrypt architecture; its tasks
consist of:
•
Controlling the generation of ECMs from different CAS vendors
•
Providing the information that each CAS requires to generate its own ECM
•
Managing the play out of the entitlement messages at the appropriate time as
requested by each CAS to be inserted into the Transport Stream
SCS functionality interfaces with EIS to receive the requests to start/stop scrambling for
each scrambling group (typically a service or a set of services) and with CWG, ECMGs,
MUX, and SCR to manage the synchronization between control words and entitlement
messages.

SimulCrypt Configuration field definitions
Definition/Range
Determines the periodicity to check communication between APEX
and other SimulCrypt entities. This parameter is common for all
SimulCrypt interfaces.
Range: 0 – 3600 (seconds)
Note: 0 means never (no channel testing procedure was performed).
Indicates the periodicity to insert the CAT table in output transport
streams.
Range: 20 – 30000 (milliseconds)
Indicates the time to wait for the response to SimulCrypt related
control messages. This parameter is common for all SimulCrypt
interfaces.
Range: 100 – 60000 (milliseconds)
Note: This parameter must be lower than the value set for the channel
test period.
Shows the preferred length of crypto periods.
Range: 1 – 3600 (milliseconds)
Indicates the additional time to account for network delays before
timing out while waiting for an ECM response.
Range: 10 – 30000 (milliseconds)
This is the initial number to be assigned for identification of the
connection with ECMG entities (ECMG channel identifier).
This parameter is used to guarantee that channel connections from
different APEX-SCS to the same ECMG entity use a unique identifier
within the headend.
Range: 0 – 20000
