Streaming Mode
OpenStream uses a session-based approach to handle resource requirements and allocation. In the course
of setting up a session, a QAM device is specified that has available capacity and connectivity to the
Streamer and the STB requesting the service. Typically, the Session and Resource Manager (SRM) is
responsible for the allocation of network resources. OpenStream uses the Digital Storage
Media-Command and Control (DSM-CC) session management protocol to request resources from the
SRM.
When using gigabit Ethernet for streaming, OpenStream communicates with the SRM to negotiate
network resources and allocation for sessions.
When using Asynchronous Serial Interface (ASI) for streaming, the Streamer performs the role of the
SRM by managing and allocating the access network resources and providing this information to the
OpenStream BMS.
Steering Ingests
The Ingest Steering feature offers the ability to have one BMS send ingest information to the master
Vault, and depending on the product ID in the content name, the content is either ingested by one of the
Vaults in the national Vault Groups, or it is ingested by a specific local Vault Group.
Note For the Ingest Steering to function correctly, the content name must be in the following format:
ProviderId::AssetId::contentName.
The Ingest Steering feature requires that VVI with central management and Vault Groups be enabled.
