Chapter 1 Product Overview
Overview
Figure 1-1 illustrates how a TV CDS network can be deployed. A business management system (BMS),
commonly called a backoffice, enables service providers to deploy on-demand services using video on
demand (VOD) servers, networks, billing systems and other system components. The asset management
system (AMS) manages the content on headend and node servers, while the BMS handles functions
related to pitching and catching. Sometimes there is some overlap of functionality between the BMS and
the AMS.
There are two types of systems available with the TV CDS: a CDS with an array of Vaults and Streamers,
and a Virtual Video Infrastructure (VVI) with an array of Vaults, Caching Nodes, and Streamers. The
CDSM manages the Vaults and Streamers in a CDS. The VVIM manages the Vaults, Caching Nodes, and
Streamers in a VVI with centralized management. For more information about network design and VVI
management, see the “TV CDS and VVI Topologies” section on page 2-2. Figure 1-1 shows a high-level
view of both a CDS and a VVI.

The Cisco TV CDS solution has three major elements:
• One or more Vault Groups consisting of one or more Vaults. The Vaults are responsible for ingest
and reliable storage of VOD content. The number of Vaults in the Vault Group, and the number of
Vault Groups is driven by the amount of content that the system offers and the degree of redundancy.
TV MediaX Suite Aids content ingest workflow and scheduling tasks for
both asset-based and real-time content
