Step 4 Choose the preference for each Stream Group. The preferences are:
• High—First preference of Streamer or Stream Group to stream to this subnet.
• Medium—Second preference of Streamer or Stream Group to stream to this subnet.
• Low—Lowest preference of Streamer or Stream Group to stream to this subnet.
• None—Do not use this Streamer or Stream Group to stream to this subnet.
Note If your CDS network is deployed with a single-site steering configuration, you only see High
and None as Stream Group Preference options, and only one Stream Group can have a
preference of high.
For more information on creating Stream Groups, see the “Configuring Stream Groups” section on
page 4-58.
Step 5 Click Submit.
To reset the fields, click Reset.
To delete a subnet, choose the subnet from the Subnet drop-down list, and click Delete Subnet.
Configuring Parent/Child Service Groups
The Parent/Child Service Groups page allows for finer granularity of the service groups created in the
Headend Setup page when ASI streaming is configured. Each service group defined in the Headend
Setup page, the parent service group, is associated with a QAM device. Each child service group is
associated with a parent service group.
Note The Parent/Child Service Group page is displayed only if the Parent/Child feature is enabled. For more
information, see the “Parent/Child Service Groups” section on page F-4.
For switched digital video (SDV), the parent service group is associated with the Streamer, while the
child service group is a subset of subscribers that have set-top boxes with switched digital broadcast
(SDB) capability. The STB sends the child service group in the session setup request.
In ASI (SSP 2.1 QAM devices), there is no specific QAM device assigned to the child service groups.
The Stream Service borrows the QAM resources from the parent service group for the child service
group during the session setup.
The STBs without SDV tune to the parent service group and send the parent service group in the session
setup request.
To configure parent/child service groups, do the following:
Step 1 Choose Configure > System Level > Parent/Child Service Groups. The Parent/Child Service Group
page is displayed.
Step 2 From the Select Parent Service Group drop-down list, choose a parent service group. The Parent/Child
Service Group page refreshes (Figure 4-9).
