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.

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
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.
