NewsBrowse Installation and Configuration Guide

Chapter 3 Configuring the NewsBrowse System

Test system interactions with multiple machines

Run the following tests to verify that all machines are available and will function
correctly, especially during times of heavy system activity.

Multiple channel ingest test

This test verifies ingest and creation of proxy assets for all channels simultaneously.

1. Make sure that the NewsBrowse system is not otherwise in use.

2. Make sure that all the Profile system channels for which NewsBrowse creates

proxy media have an appropriate media feed.

3. On the NewsBrowse server, open Thomson Event Viewer.

4. In the NewsBrowse application, schedule ingest events on each channel to occur

all at the same time.

5. Once the events start recording, select the find tab on the left side of the application

and press the go button with no criteria specified. Assets with the event names
should appear in the results list.

6. Select an asset from the results list to load the details on the right side of the

application. Video should be visible.

7. After the recording is complete, reload assets and verify that thumbnails and

storyboards are created as well. Depending on how your rules are set up, this can
take up to two times the duration of the original media.

Multiple scavenge test

This test verifies that scavenge operations can simultaneously control all Advanced
encoders and appropriate Profile channels to optimize performance during times of
heavy proxy asset creation.

To test multiple scavenge operations, do the following:

1. Prepare a quantity of test clips on a Profile system, such that you have one more

test clip than the number of Advanced encoders in your system. For example, if you
have four Advanced encoders, prepare five test clips. You must prepare the test
clips without triggering the NewsBrowse system to create any proxy assets. You
can do this by recording media with a channel that is not associated with the
NewsBrowse system for ingest, or by copying existing clips to a different bin. In
any case, the bin in which these test clips are initially placed must not be a bin that
is currently monitored by the NewsBrowse system for scavenge operations. Make
the test clips at least a minute long.

2. On the NewsBrowse server, open Thomson Event Viewer.

3. Prepare a Profile system bin (preferably a bin that is currently empty) for

monitoring by the NewsBrowse system for scavenge operations. Define a “Create
Proxy MPEG if Profile movie…is created” rule for the bin. It is not necessary to
create “Create Proxy” rules for the creation of other proxy assets, as this
functionality is tested in the previous

“Multiple channel ingest test”

.

4. On the Profile system, use Media Manager to simultaneously copy all the test clips

into the prepared bin.
