Entitlement Control Message Generation
In contrast to the traditional DAC 6000-queued operation supported by the SEM, the
APEX1000 internally generates the appropriate ECMs at the same time as it performs
the encryption.
While in all cases the APEX1000 internally creates the ECMs, the access requirements
(Rights Meta Data) for a given stream are determined by the APEX1000 by the DAC
(through its RDS interface), by the session controller setting up a VOD session, or
through configured defaults on the APEX1000. The actual method depends on the
encryption mode:
•
Broadcast Encryption
•
Common Tier Encryption
•
Session VOD Encryption
Broadcast Encryption
RMD from the DAC — Use this mode for unique tier and other access requirements
applied to each service, and retrieved using the DAC's Rights Data Server (RDS) XML
interface. In this manner, the APEX1000 behaves similarly to the NE1000 Network
Encryptor.
CAUTION Use the RMD from the DAC mode only for manually routed services.
Common Tier Encryption (CTE)
RMD configured on the APEX — Use this mode to apply default access requirements
across all services. The same operator configured tier value is applied to all services
encrypted in this mode.
Note: This mode is typically used for UDP port mapped VOD services or session
controlled switched digital video services, but you can also use it for manually routed
services.
MHA VOD Session Encryption
The APEX1000 supports session-based encryption in MHA mode.
In this mode, a set-top client is assigned a unique tier by the DAC. When the set-top
requests a VOD session, in addition to access requirements for the VOD service, the
session controller passes a set-top identifier to the APEX1000 in the RTSP session setup
message. The APEX1000 uses this information to encrypt the session with the same
unique tier assigned to the set-top by the DAC and the appropriate rights meta data.
Note: Only the requesting set-top may decrypt the session.
