Overview
The Cisco TV Content Delivery System (CDS) is a distributed network of Content Delivery Engines
(CDEs) running Content Delivery Applications (CDAs) that collaborate with each other to deliver
personalized entertainment and interactive media to subscribers.
The Cisco TV CDS has a variety of mechanisms to accelerate the distribution and delivery of content.
The CDS interoperates with electronic program guides (EPGs), set-top boxes (STBs), and backoffice
applications, offering an end-to-end solution for video delivery systems.
The Cisco TV CDS functionality can be separated into five areas:
• Ingest
• Storage
• Caching
• Streaming
• Management
Each CDE in the CDS contributes to one or more of these functions as determined by the CDAs running
on it. Table 1-1 describes the relationship between the CDA names and the names the TV Content
Delivery System Manager (CDSM) uses.
