Revision A1
Repeater Test
Description
 Verifies hot plug detect is asserted.
 Verifies EDID (bad header, bad checksum, pass/fail on
compliance)
 Indicates if the EDID was modified.
 Verifies timing pass-through.
 Checks if video was passed through unchanged or not.
 If timing is passed through, test will also verify if the video is
passed through without color manipulation.
 Verifies HDCP authentication and if repeater acts as an HDCP
repeater or not and verifies that it acts properly as an HDCP
repeater.
 Test port switch on HDTV with HDCP re-authentication
Link Test
Description
 Tests the maximum number of HDCP keys (max dev count)
supported by the source device during HDCP authentication.
 Verifies hot plug detect is asserted.
 Verifies EDID (bad header, bad checksum, pass/fail on
compliance).
 Runs an HDCP authentication test on both source and sink.
 Runs a video test at EDID preferred timing, with HDCP
enabled.
 Test port switch on HDTV with HDCP re-authentication
 Verifies the incoming video at various timings
 Verifies video timing parameters.
7.1 Diagnosing HDMI and HDBaseT Interoperability Problems toward the
Source - Upstream
This subsection describes how to diagnose HDMI and HDBaseT interoperability problems on HDMI/HDBaseT
source device—upstream (Source Test).
7.1.1 Connection Configurations for Testing HDMI Source Devices
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 diagnostics upstream toward the source device. The following
illustrations show the typical configurations.
