6.3 Testing HDCP Max Devices on an HDMI Source Devices and Outputs of
HDBaseT distribution Devices
This subsection describes how to run a test of the number of HDCP devices an HDMI or HDBaseT source
device supports. The Max HDCP devices test runs a test on the source device (such as a DVD or STB) to
determine how many downstream devices are supported during an HDCP authentication with a repeater
device.
6.3.1 Configurations for Testing Max Devices an HDMI Source Device Supports
The 780C’s HDMI input port acts as a “reference” HDMI sink device. Therefore it enables you to emulate a
known good HDMI sink device to conduct a test on a source device. You can run this source device connected
directly to the 780C. This test configuration is shown below.
6.3.2 Procedures for Testing Max Devices a Source Device Supports
Use the following procedures to test the maximum number of HDCP devices a source device supports.
1. Connect the HDMI system devices to the 780C as shown in the diagram above. The HDMI source device
or HDBaseT device output is connected the 780C HDMI IN or HDBaseT IN connector.
2. Enable the HDMI as the active digital interface input as shown below.
