10.2 Running a video analysis test

The procedures below describe how to run the video analysis test on an HDMI source device through the 980
Manager. The Video Analysis panel enables you to view the captured video images. It provides thumbnails of
each captured frame. It also enables you to navigate to the Data Decode panel to view the transactions for that
frame. The Video Analysis panel can synchronize with the Data Decode panel by pressing the ALT key and
clicking on a frame. You can also synchronize by activating the sync button
Data Decode panel. Once you synchronize the Data Decode panel to a frame you can view the transactions for
that frame in the Data Decode panel.
The setup procedures described above in the section:
should be followed for the video analysis tests. These setup procedures are listed below:
1. Configure the 980 HDMI Protocol Analyzer in the proper mode HDMI.
2. Set the threshold of the +5V.
3. Configure the 980 Rx port with the proper EDID.
4. View the incoming video in real time to check the status of the device under test.
To run the video analysis test:
1. Select the 980 HDMI Protocol Analyzer that you are using to capture the data from your HDMI source device
under test from the pull-down menu.
2. Set the Capture Buffer Size slidebar to a percent value to meet your requirements. You can capture up to
about 2GB of data which is about 1150 frames at 576p/480p and about 204 frames at 1080p which includes
the video. If you do not want to capture the video and only capture the metadata, you can store well over
100,000 frames of data.
3. Set the Capture Buffer Position slidebar to a percent value to meet your requirements. This slide bar enables
you to set the position of the trigger event within the captured data. This is a slidebar that provides an
indication (on the right) of the location within the captured data, expressed as a percent with 0% indicating that
the trigger event occurs at the beginning of the captured data and 100% indicating that the trigger event occurs
at the end of the captured data.
4. Select the Capture tab under the Options section of the Capture Control panel.
