Cisco DNCS System Release 2.8.1 3.8.1 4.3.1 User Guide

This section discusses defining sources and setting up sessions. 

In the DBDS, a source is the actual program or data that is made available to the DHCT as a service to the
subscriber. Sources can include: MPEG-2 digital broadcast services that are non-secure, non-encrypted,
audio/video programs; Internet connections from an Internet service provider (ISP); Digital PPVs that are secure,
encrypted, digital MPEG-2 programs; Digital music services; Analog programs that are modulated in the
traditional format or converted into MPEG-2 format.

Sessions are the logical elements that define and allocate the resources that the network uses to deliver source
content.
