Add a Service Group
Introduction
If you are going to provide VOD, xOD, or SDV services, you must add a service
group for each VOD, xOD, or SDV server in your network, along with the associated
GQAMs. A service group is a set of GQAM modulator channels that have been
combined to provide narrowcast services (VOD, xOD, or SDV) to a unique group of
DHCTs. Service groups enable DHCTs to distinguish which GQAM is providing
which service.
You can create the following types of service groups:
You can create the following types of service groups:
Parent service groups: service groups which contain one or more child service
groups
Child service groups: service groups which belong to a parent service group
Standalone service groups: service groups which are independent; they contain
no child service groups nor do they belong to a parent service group
Note: Allowing one service group to belong to another enables you to more
effectively manage the different types of content that a server provides.
Before You Begin
Before you begin, you must have your network map. If you cannot locate your
network map, contact Cisco Services. You must also know which GQAM will be
providing data for each VOD, xOD, or SDV service.
