ECM Generators
ECM generator is provided by CAS supplier to produce ECM messages.
•
Name:
Only used in web interface to easily identify separate ECMG servers
•
Channel ID <optional>:
‘ECM_channel_id’ used when communicating with ECMG. Some ECMGs require a specific value for
this ID (info if necessary from the CAS supplier). If left empty, device uses some unused random ID.
•
Remote IP:
IP address of the ECMG server to connect to.
•
Port:
Port of the ECMG server to connect to.
•
CAS:
CA system of this ECMG (name from the CAS table)
•
Status:
ECMG server connection status shown as traffic lights
4.10.5.
ECM List
ECM contains CAS supplier private information which carries the control word (encryption key) in a secure manner and private
entitlement information. Each ECM entry corresponds to one generated ECM stream. Each SCG requires at least one ECM stream,
otherwise nobody is able to descramble.
•
ECM Generator:
ECM generator responsible for generating this ECM stream (value from ECM Generator list)
•
ECM ID <optional>:
‘ECM_id’ used when communicating with ECMG. Some ECMGs may require a specific value for this
(info from CAS supplier). If left empty some random ID is used.
•
SCG:
Scrambling Control Group whose control words are transmitted by this ECM (value from SCG table)
•
Access Criteria:
Arbitrary binary data transmitted to the ECMG. Typically used to tell the ECMG which clients should be able
to decode the ECMs. Format and value is given by CAS supplier.
•
Private Data:
Arbitrary binary data included as ‘private_data’ in the CA_descriptor of the PMT associated to this ECM (info
from CAS supplier).
•
Status:
ECM stream status shown as traffic lights.
