input for testing HDMI, HDBaseT or SDI source devices. You can run a verification test of a video source which includes timing and format information and an indication of whether the video is HDCP content protected.
Data Island test of an HDMI or HDBaseT source device – The 780C provides an HDMI/HDBaseT input for
testing HDMI or HDBaseT source devices. You can view the infoframes and other data islands.
Audio test of an HDMI, HDBaseT or 3G-SDI source device – The 780C provides HDMI, HDBaseT and 3G-
SDI inputs for testing source devices. You can run a verification test of an audio source which includes decoding of the audio IEC headers, audio infoframes and audio sample packet headers (for HDMI and HDBaseT and parsing out of the channel status bits for 3G-SDI as well.
EDID test of HDMI or HDBaseT source device or outputs – The 780C’s HDMI or HDBaseT input ports can
be provisioned with any EDID you have access to. You can verify that a source device responds properly to the provisioned EDID. The EDID could be a known-good EDID or an EDID that you have created specifically for testing.
HDCP test of an HDMI or HDBaseT source device – The 780C enables you to run a test to determine how
many HDCP devices an HDMI or HDBaseT source can support during HDCP authentication.
CEC ping test of any HDMI device – The 780C enables you to run a CEC ping test on an HDMI device.
1.4.3 Cable and Repeater test features
The following features are available with the Cable and Repeater test option: Cable & Repeater test – Because the 780C has both digital video inputs and outputs, you can loop a cable
or entire distribution networks comprised of splitters, extenders, repeaters, switches, even hybrid networks with HDMI, HDBaseT or 3G-SDI components, from the 780C’s output to input and run a pseudo-random noise pattern test to determine pixel errors on the TMDS lines. The feature also runs a continuity test on the HDMI or HDBaseT DDC test pair, CEC bus, the +5V line and the hot plug lead. The Repeater test also shows you the hot plug delay between the downstream side and the upstream side and the pulse width. The Cable & Repeater Test enable you to test a cable, repeater or distribution network if the source and sink ends are collocated. If the source and sink ends are not collocated then you need to use the Frame Compare test described below.

4.2.2 Procedures for Selecting an Resolution and Frame Rate – HDMI and HDBaseT
The procedures below describe how to select the resolution for HDMI and HDBaseT outputs. Note: You can create your own custom formats using the Quantum Data Format Editor. These procedures are
described in Creating and Using Custom Formats, EDIDs and Bitmaps. When you make a physical connection to an HDTV or monitor, a hot plug event will occur. There are two
modes the 780C can be set in when testing HDMI or HDBaseT sink devices that determine how the 780C responds to this hot plug event: 1) Hot plug formats On; 2) Hot plug formats Off.
When hot plug formats are On and a hot plug event occurs, the 780C will read the EDID of the display device connected to its output port. It will then automatically configure the list available signal types (resolutions and frame rates) to only those supported by the HDMI or HDBaseT sink device. The 780C will also be configured to output the signal indicated in the EDID as the “preferred” timing. The preferred timing is highlighted in green following a hot plug event.
When hot plug formats are Off, the 780C will display all viable HDMI or HDBaseT formats for the interface whether they are supported by the display or not.
1. Select the Preferences from the 780C top level menu. Navigate to the second page by touch selecting the More… key.
September 29, 2014

The Formats menu appears as shown below (example HDMI):
4. Touch select the desired format and Frame Rate (example 2160p at 30Hz above).
For the HDMI formats, there are color codes that are applied to the Resolution and Frame Rate selections. The following is a summary of their meaning:
A Resolution or Frame Rate with white lettering but with no outline – a Resolution or Frame Rate that
appears in the EDID and has a short video descriptor associated with it.
A Frame Rate with green lettering and with white outline – The Frame Rate that is currently selected.  A Frame Rate with red lettering but with no outline – The Frame Rate is not supported by the EDID for
that Resolution.
A Frame Rate(s) with green lettering and with white outline – The Frame Rate along with the currently
selected Resolution that is the “preferred” timing.
September 29, 2014
Revision A1
A Frame Rate with black lettering but with no outline – The Frame Rate is not supported by the standard
for the selected resolution. Note: When you make a physical connection to an HDMI or HDBaseT HDTV or sink device, a hot plug
event will occur. If Hot Plug Formats is enabled on the Preference menu, when the hot plug event occurs, the 780C will read the EDID of the display device connected to its output port. The output is automatically set to the preferred timing which is highlighted in green following a hot plug.
4.2.3 Procedures for Enabling AVMute
The procedures below describe how to enable AVMute on the HDMI or HDBaseT output ports. AVMute is an optional feature in HDMI or HDBaseT that enables a source to signal a sink to extinguish its audio and video.
