Chapter 3 Configuring the NewsBrowse System
5. Open the NewsBrowse application and on the Ingest page verify that the video
stream appears.
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. This takes approximately two times the duration of
the original media so for example you must wait at least two minutes after
completion of recording a one minute asset.
Multiple scavenge test
This test verifies that scavenge operations can simultaneously control all sequential
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 sequential encoders in your system. For example, if you
have four sequential 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
sequential encoder “Create Proxy MPEG if Profile movie…is created” rule for the
