112 Chapter 13 Testing HDCP on HDMI
Running HDCP test in step mode
The 882 normally runs the steps in the HDCP test automatically. However, to troubleshoot
a failed test, you can run the test in “step” mode. This enables you to read the values at
the step where the test failed.
To run the HDCP test in step mode:
1. Connect a cable between the HDMI OUT connector on the 882 and the device’s input.
2. Activate the HDMI-H or HDMI-D interface on the output port as follows:
a. Press the Interface key. A listing of signal interfaces appears on the 882’s display
as shown below (HDMI shown in the example only).
b. Choose either the HDMI-H or HDMI-D item by pressing the adjacent soft key. The
interface is activated, and the port outputs the currently selected image and format.
Alternatively, to activate the interface through the command line interface, enter the
following commands:
XVSI 4 // Activates the HDMI-H interface (3 for HDMI-D)
ALLU // Applies the interface setting to the 882
3. Press the Content key and choose the HdcpProd image by pressing the adjacent soft
key. Or, if you are using HDMI OUT port 2, choose the HDCP2 test image.
4. Enable and view image versions for the test image as follows:
a. Press the Options key. The following menu appears on the 882’s display:
b. Choose the More item by pressing the adjacent soft key until a + and Rendition
appears next to the item.
c. Press the + key to advance through the image versions.
Alternatively, to enable and view image versions using the command line interface,
enter the following commands:
