6.3 Testing HDCP Max Devices on an HDMI Source Device
This subsection describes how to run a test of the number of HDCP devices an HDMI 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 a Source Device Supports
The 780’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 780.
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 780 as shown in the diagram above. The HDMI source device output is
connected the 780 HDMI IN connector.
2. Touch select Test Source (DVD/STB) from the top level menu shown below.
