Games and Services
Application Server
The Games and Services Application Server is the key storage
device for a suite of On Demand services providing
additional revenue opportunities to Service Providers. The
Server stores games and services applications, data for the
applications, and graphics for portions of the user interface
that run on the Cisco set-tops. The Server interfaces with the
Broadcast File System (BFS) of the DNCS to allow the
applications, data, and images to be sent to the set-top over a
broadcast channel. The Server can be configured to fetch
data for the applications on a schedule as determined by the
Service Provider. This allows, for instance, a weather
application to have updated weather information every 15
minutes.
DNCS
Digital Network Control System. A centralized server located
at the Digital Broadband Delivery System (DBDS) headend,
its primary function is to manage digital services and service
delivery to RF set-tops in the DBDS cable network. The
DNCS monitors and controls DBDS network elements and
provides management, provisioning, and configuration
through the DBDS to RF set-tops and other compatible set-
top converters, and provisions sessions on the PCG. The
DNCS also hosts the PowerKEY
®
conditional access system
(CAS) that enables secure delivery of services to set-tops and
provides support for set-top applications via the BFS. The
DNCS can be offloaded by the Regional Network Control
Server (RNCS) which supports BFS and EAS delivery at a
remote site.
