780C Multi-Interface Interoperability Tester – User Guide Page 134September 29, 2014 Revision A1Repeater Test Description Verifies hot plug detect is asserted. Verifies EDID (bad header, bad checksum, pass/fail oncompliance) 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 ispassed through without color manipulation. Verifies HDCP authentication and if repeater acts as an HDCPrepeater or not and verifies that it acts properly as an HDCPrepeater. Test port switch on HDTV with HDCP re-authenticationLink 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 oncompliance). Runs an HDCP authentication test on both source and sink. Runs a video test at EDID preferred timing, with HDCPenabled. 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 theSource - UpstreamThis subsection describes how to diagnose HDMI and HDBaseT interoperability problems on HDMI/HDBaseTsource device—upstream (Source Test).7.1.1 Connection Configurations for Testing HDMI Source DevicesThe 780C’s HDMI input port acts as a “reference” HDMI sink device. Therefore it enables you to emulate aknown good HDMI sink device to conduct diagnostics upstream toward the source device. The followingillustrations show the typical configurations.
