Figure 2-10 shows a high-level view of Ingest Steering for a single, centralized BMS and multiple
VHOs. Each VHO has a local Vault Group through which all local live content is ingested. Each Stream
Group streams local live content as well as national live and VOD content. The BMS sends messages to
the master Vault Group (Vault Group 1), and depending on the product ID and the ingest steering
configured, the content is ingested by either the local Vault Group or the national Vault Group.
Content objects on the national Vault Groups are mirrored among each other, while the content on the
local Vault Groups are copied to separate hard drives on each Vault.

Network Connections
The network connections for a TV CDS with Vaults and Streamers, a TV CDS with ISVs, and a TV VVI
with Caching Nodes all have different network connections. Table 2-2 lists the different required
interfaces for each CDS server. The interfaces are described in the following sections. Figure 2-11
illustrates a TV CDS with Vaults and Streamers. Figure 2-12 illustrates a TV CDS with ISVs.
Figure 2-13 illustrates a TV VVI with Caching Nodes.
