BMS Considerations for ISA Environments
In Release 2.5.2, Vault Virtualization replaces the SCS with the Virtual Content Store (VCS). No content
is ingested at the local VHO. All ingests and deletions of content occur at the central location, and both
ingests and deletions are initiated by the local BMS at each local VHO, just as they were in the SCS.
However, the VHOs do not need to communicate with the super headend (SHE) as they did with the SCS
feature. With VCS, communication of ingestions and deletions is handled by the Ingest Driver client
residing on a Streamer in each VHO and the Ingest Driver server residing on the master Vault in the SHE.
Vault Virtualization requires that Vault Groups be disabled.
The Virtual Content Store (VCS) component runs on a Streamer in the Stream Group, and if a failover
occurs, the VCS fails over to another Streamer in the Stream Group.
Only one copy of the centrally located asset is ingested and shared by the system, and the asset is only
deleted when all VHOs have requested the deletion.
With the VCS, the MSV Asset Deletion script is no longer needed and is removed during the software
upgrade to Release 2.5.2.
For information on configuring Virtual Content Store, see the “Virtual Content Store Configuration
Workflow” section on page 3-10.
BMS Considerations for ISA Environments
The TV CDS integrates with Interactive Services Architecture (ISA) used in business management
systems (BMSs) such as the Tandberg OpenStream and the RTSP used in BMSs such as ARRIS nABLE,
as well as in environments that are a combination of both ISA and RTSP. The BMS determines the roles
and responsibilities of the TV CDS.
OpenStream ISA Integration
The OpenStream BMS is built on Common Object Request Broker Architecture (CORBA) and provides
naming and notification services. The Naming Service allows the TV CDS to locate objects in the system
such as content, equipment, assets, and so on. The Notification Service allows the TV CDS to listen for
important events in the system as well as to send events to the OpenStream BMS and other components
in the system.
Note Dual conditional access systems (CAS) for ISA environments, Cisco/Scientific Atlanta Power Key
Encryption System (PKES) and the Motorola OffLine Encryption Station (OLES), is supported. A field
on the Monitor Completed Ingests page indicates whether the ingested content is encrypted or not. Both
clear and encrypted content can be ingested.
For more information on the configuration parameters required to facilitate communication between the
OpenStream BMS and the TV CDS, see Appendix C, “BMS Communication.”
Figure 2-9 illustrates how the TV CDS integrates with the OpenStream BMS.
