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

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.

780C Multi-Interface Interoperability Tester – User Guide Page 26

January 19, 2017

Revision A9

2. Select the Hot Plug Formats mode to On or Off as desired. Refer to the screen above.

3. Touch select the Formats activation button on the Status bar OUT to access the Formats menu. Refer to
the figure below.

780C Multi-Interface Interoperability Tester – User Guide Page 27

January 19, 2017

Revision A9

The Formats menu appears as shown below (example HDMI):

4. Touch select the desired format and Frame Rate (example 2160p at 30Hz above).
Note: The 780C supports 4K formats at 60Hz but only in 4:2:0 sampling mode. When a 4K format is

selected and the frame rate is set at 60Hz the 780C will automatically configure itself to 4:2:0
sampling. Refer to the example below:

780C Multi-Interface Interoperability Tester – User Guide Page 28

January 19, 2017

Revision A9

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.

 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.
The source, in this case the 780C emulating a source sets the AVMute Set flag in the general control packet.
The purpose of AVMute is to avoid audio artifacts when switching resolutions.

3D Color Ramp

Application: This is a 3D
pattern used to test 3D color
uniformity and crosstalk or
extinction ratio.

No variants

Description: There are 4 pairs of horizontal color bars. Each bar
depicts a color gradation from red to purple; two from left to right
and one from right to left.

Method – Color uniformity:

1. Close left eye to view image from right eye.

2. Assess the color gradation on each bar.

3. Close right eye to view image from left eye.

4. Subjectively compare the images to assess color

uniformity.

Method – Crosstalk (extinction ratio):

1. Close left eye to view image from right eye.

2. Verify that the bottom bar is extinguished. The extent to

which the bar is not extinguished represents the amount
of crosstalk.

3. Repeat for a test of the left eye

3D Cross Talk

Application: This is a 3D
pattern used to measure the
crosstalk (extinction ratio) for
frame packing, top and bottom
and side by side 3D format
structures.

No variants

Description: This image is divided in two sections with four rows of
16 white boxes each. The top section is for testing with the left eye
open. The bottom section is for testing with the right eye open.
The background area surrounding the boxes is a series of
grayscale ramps. The ramps begin at 100 IRE and transitions to
50 IRE at the left end of the fourth row of each series.

Method – Calculating percent crosstalk:

1. Close right eye to test the left eye using the top section.

2. Check the visibility of the boxes. Any deviation from

black indicates crosstalk.

3. Assess where the box and its background blend such

that they are not distinguishable.

4. Calculate the degree of crosstalk as a percent by

counting the number of boxes (from the beginning of the
series to the box identified in step 3) and divide that by

127. Example if the 20th box blends with its background,
the crosstalk would be 20/127 * 100 = 15.7%

5. Repeat with the left eye closed to test the right eye.

4.4 Using Custom Test Image Packs

The 780C provides licensed image packs for certain sets of test images. You need to have a license key to use
these custom test image packs. You can arrange to get access to them by contacting Quantum Data customer
support at: http://www.quantumdata.com/support.

Note: The custom test image packs are bitmap images. Bitmap images are RGB and will not display properly
on the 3G-SDI output.

When you purchase an image pack it appears as an icon at the end of the list of Test Patterns. A sample
screen is shown below (Philips1, ChinaRes, Master). You simply select one of the test patterns (e.g. ChinaRes
in the screen example below). They will take a few seconds to load. They will load at the resolution of the
format that you have selected.

Refer to the tables below for a description and depiction of the Image Packs currently offered.

4.5 Outputting 3D Test Patterns through HDMI or HDBaseT

This subsection describes how to render 3D test patterns on an HDTV. The 780C supports Side-by-Side, Top­and-Bottom and Frame Packing (for both interlaced and progressive timings) 3D format structures.

4.5.1 Configurations for Rendering 3D Bitmaps on an HDMI or HDBaseT Sink Device

Typically you will render 3D bitmap images with the 780C directly connected to an HDTV or projector. This
configuration is shown below:

780C Multi-Interface Interoperability Tester – User Guide Page 48

January 19, 2017

Revision A9

4.5.2 Procedures for Obtaining 3D Bitmaps on HDMI or HDBaseT Sink Device

Use the procedures below to render 3D bitmap images on an HDMI sink.

1. Follow the procedures provided above to enable the HDMI output as the Signal Type.

2. Obtain 3D bitmaps. You can obtain 3D bitmaps in three ways:

 Develop your own 3D bitmaps.
 Sample 3D bitmaps from the Quantum Data website (www.quantumdata.com/downloads).
 Generate 3D bitmaps from your own stereoscopic image pairs using the Quantum Data 3D Bitmap

Conversion Tool available from the Quantum Data website (www.quantumdata.com/downloads).

3. Transfer your 3D bitmaps over to the 780C using the procedures described in Importing Custom Bitmaps.

4.5.3 Procedures for Rendering 3D Bitmaps or 3D Test Patterns on HDMI or HDBaseT Sink Device

1. Select a format that is suitable for rendering 3D images such as 720p60 and 1080. Use the procedures
above Procedures for Selecting an HDMI Resolution and Frame Rate.

If you have used the Quantum Data 3D Bitmap Conversion Tool, there is a naming convention for the 3D
bitmaps which also provides the required format for each specific bitmap.

2. Enable the HDMI or HDBaseT as the active digital interface input.

780C Multi-Interface Interoperability Tester – User Guide Page 49

January 19, 2017

Revision A9

3. Touch select 3D Output option from the top level menu shown below.

The following screen will appear:

780C Multi-Interface Interoperability Tester – User Guide Page 50

January 19, 2017

Revision A9

4. Select the 3D mode (Side-by-Side, Top-and-Bottom or Frame Packing) and then select the subtype and
Left/Right options (if applicable).

5. Select the 3D bitmap or image image from the Test Pattern list.

780C Multi-Interface Interoperability Tester – User Guide Page 51

January 19, 2017

Revision A9

Note: If you are using one of the 3D bitmaps (as opposed to a standard 3D test pattern) you will have to make
sure that the 3D bitmap you use matches your selection of 3D formats and timing (resolution). In the example
above, a 3D Frame Packing bitmap is selected for 1280 x 720. Therefore you have to make sure that you
select that specific timing (i.e. 1280 x 720) and that specific 3D format structure (Frame Packing).

4.6 How to Scroll or Pan a Bitmap Pattern

This subsection describes how to scroll bitmaps on your 780C.

Note: The bitmap images are RGB and will not display properly on the 3G-SDI output.

4.6.1 Guidelines for Scrolling Bitmaps

There are two ways you can animate (move) a bitmap image: 1) image shifting (scrolling); 2) panning. You can
shift or scroll a bitmap image that you have imported into the 780C by modifying the X and Y parameters or by
dragging and panning. When you use the X and Y parameters, you are limited to linear scrolling. With panning
you can move the image in non-linear motions.

You can only scroll bitmaps whose overall pixel resolution is smaller than the resolution of the active format and
you can only scroll them within the bounds of the resolution of the active format. You cannot scroll the standard
test patterns in the 780C.

In order to scroll a bitmap the name of the bitmap has to be “zp.bmp.” But you can scroll any bitmap. You just
have to make sure that you have named it “zp.bmp” (without the quotes). The zone plate bitmap is the only
bitmap that comes standard with the 780C.

4.6.2 Procedures for Scrolling Bitmaps

Use the following procedure to scroll your bitmaps.

1. Touch select the desired bitmap image, e.g. Zone Plate image from the list of video patterns.

780C Multi-Interface Interoperability Tester – User Guide Page 52

January 19, 2017

Revision A9

2. Double touch select on the Zone Plate bitmap to access its options.
The Zone Plate Options menu appears:

3. Specify the Horizontal Movement by touch selecting the appropriate setting Slow, Medium, Fast.

4. Specify the Vertical Movement by touch selecting the appropriate setting Slow, Medium, Fast.
The pattern will begin to move around the raster of the display in accordance with the horizontal and

vertical settings. To halt the motion, touch Stop for either or both of the Horizontal Movement and

Vertical Movement.

4.6.3 Procedures for Panning Bitmaps

780C Multi-Interface Interoperability Tester – User Guide Page 53

January 19, 2017

Revision A9

Use the following procedure to pan your custom bitmaps.

1. Select by double touching, the desired bitmap image, e.g. Master 1920x1080 image from the list of video
patterns (shown below).

2. Double touch select on a bitmap to access its options. The screen below appears.

3. Select Manual Panning to initiate the panning operation.

The message shown on the screen below will appear.

4. Simply move your finger or stylus around the screen to pan the image.

This section provides procedures for testing digital audio on an HDTV or A/V Receiver.
Note: It is recommended not to select bitmap images when outputting compressed audio clips.
Table 4-5 below summarizes the 780C support for digital audio.

4.7.1 Connecting the 780C to an Audio Rendering Device

Use the following procedures to make the physical connections from the 780C to the audio rendering device
under test.

780C Multi-Interface Interoperability Tester – User Guide Page 56

January 19, 2017

Revision A9

1. Make the cable connection between the appropriate the 780C video output connector (e.g. HDMI OUT,
SPDIF or OPTICAL) and the input connector of the audio rendering device using the cables supplied.

Alternatively you may connect from the 780C video output connector to an HDTV through an HDMI
repeater device such as an A/V receiver. In this case make the HDMI connection between the HDMI OUT
connector on the 780C and the HDMI input of the HDMI repeater device using an HDMI-to-HDMI cable.
Then connect the HDTV to an active output on the repeater. The following illustrations depict the typical
test configurations.

The following illustrations depict the test setups for the HDMI audio, SPDIF audio and optical (TOSLink).
Note also that you can test directly into an HDTV without going through an A/V receiver.

6 Using the 780C Test Instrument to Test HDMI or HDBaseT Source

Devices

This section provides procedures for testing HDMI source devices such as DVD players, set top boxes and
HDMI and HDBaseT outputs on repeater and distribution devices.

6.1 Testing Video from an HDMI Source Device

This subsection describes how to test the video on HDMI source devices.

6.1.1 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 a basic confidence test of an HDMI source device or output of an
HDMI distribution or repeater device. This test ensures that you are receiving a valid HDMI video signal by
displaying the timing of the incoming signal and informing you whether it is HDCP encrypted or not. You can
run this test in three configurations:

 Source device connected directly to the 780C HDMI IN connector.
 Source device connected to the 780C HDMI IN connector through a repeater device.
 780C HDMI OUT and HDMI IN ports acting as both as a known good source and a known good sink

connect to both the input and output of the repeater device.

In all cases the 780C is emulating a sink to test an upstream source. In the third configuration, the 780C is
emulating both an HDMI source and sink. These test configurations are shown below.

780C Multi-Interface Interoperability Tester – User Guide Page 88

January 19, 2017

Revision A9

6.1.2 Connection Configurations for Testing HDBaseT Outputs on Repeater and Distribution Devices

The 780C’s HDMI input port acts as a “reference” HDBaseT sink device. Therefore it enables you to emulate a
known good HDBaseT sink device to conduct a basic confidence test of an HDBaseT output of an HDBaseT
distribution or repeater device. This test ensures that you are receiving a valid HDBaseT video signal by
displaying the timing of the incoming signal and informing you whether it is HDCP encrypted or not. You can
run this test in three configurations:

 Source device connected to the 780C HDBaseT IN connector through a repeater device.
 780C HDBaseT OUT and HDBaseT IN ports acting as both as a known good source and a known good

sink connect to both the input and output of the repeater device.

In all cases the 780C is emulating a sink to test an upstream source. These test configurations are shown
below.

6.1.5 Viewing Video Metadata from an HDMI/HDBaseT Source Device

Use the following procedures to verify the video metadata and video timing data from an HDMI/HDBaseT
source device.

Important Note: The Format Analyzer test is supported by the Report File Creation feature which enables the
results of the test to be included in an html report that can be disseminated or printed. However, the Report
Menu entry on the top menu has not been updated on the screens in this subsection. Refer to the Chapter on

Report File Creation for details on generating reports.

You can either view it unscaled on a 4K display, or scaled to 1080p or scaled to 1920 by 1080 resolution.
Refer to Table 6-1 below:

1. Enable the HDMI or HDBaseT as the active digital interface input as shown below.
