Cisco Model D9500 Switched Digital Video Server (NTSC and PAL) Data Sheet
Description
The Model D9500 Switched Digital Video (SDV) Server is an
integral component of the Scientific Atlanta SDV system.
Based on a standard Linux platform, the SDV Server
functions as a distributed Session and Resource Manager
(SRM) for Switched Digital Video. This high-performance
server processes SDV channel change requests, manages
resource allocations in the edge modulators, binds multicast
content to available resources, and maintains up-to-date
information on all switched digital content being viewed. This visibility gives the operator the flexibility to optimize
the SDV system for bandwidth efficiency and to improve targeted services. This information is also used to
generate a Mini-Carousel file which provides tuning information to the set-tops over the in-band video channel.

The SDV software has been designed for increased availability, providing N:1 redundancy with automated failover
in the case of a failure or maintenance event. These servers may be centralized for operational efficiency or
distributed for greater scalability. Each server is managed by the SDV Manager in the Scientific Atlanta Digital
Network Control System (DNCS) which also acts as an application independent Master SRM for resource sharing
among multiple applications. Single-step provisioning in the DNCS allows the operator to easily manage the
entire SDV system.
