Overview
The CVT download method loads client software onto Explorer® set-tops at a speed
more than twice as fast as the previous Operating System Manager (OSM) download
method.

method.
If you are familiar with the OSM method, keep in mind that the CVT method works
a little differently. For example, the CVT method does not use the carousels created
and managed by BFS. Instead, the OSM process creates and manages its own
carousel for the delivery of images identified in the CVT table. In addition, specific
to a distributed BFS configuration, the secondary QAMs use continuous feed
sessions to distribute the BFS and OSM data to the secondary QAMs.

Time To Complete
Configuring the CVT download method can take up to two hours to complete.
Add an MPEG Source
If you have not already added one, your next step is to add an MPEG source to its
corresponding QAM on the DNCS. See Add an MPEG Source (on page 12) for the
instructions.

After you add the MPEG source to its corresponding QAM on the DNCS, your next
step is to verify that all DNCS processes are running. Go to Confirming That All
DNCS Processes Are Running (on page 39).
