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 780D can be set in when testing HDMI or HDBaseT sink devices that determine how the 780D
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 780D 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 780D 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 780D 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 780D top level menu. Navigate to the second page by touch selecting the
More… key.

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.
The Formats menu appears as shown below (example HDMI):
July 4, 2017
Revision A8
780D HDMI Protocol Analyzer / Generator – User Guide
Page 25
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.
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 780D 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 780D 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.
1. Select the Preferences from the 780D top level menu. Navigate to the second page by touch selecting the

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

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.
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.
PGCWRGB Pattern
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.

Application: This is a scrolling

Outputting 3D Test Patterns through HDMI or HDBaseT
This subsection describes how to render 3D test patterns on an HDTV. The 780D 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 780D directly connected to an HDTV or projector. This
configuration is shown below:

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 780D 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.

5. Select the 3D bitmap or image from the Test Pattern list.
July 4, 2017
Revision A8
780D HDMI Protocol Analyzer / Generator – User Guide
Page 47
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 780D.
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 780D 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 780D.
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 780D.
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.

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.

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 780D’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 780D HDMI IN connector.
Source device connected to the 780D HDMI IN connector through a repeater device.
780D 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 780D is emulating a sink to test an upstream source. In the third configuration, the 780D is
emulating both an HDMI source and sink. These test configurations are shown below.

Testing an HDMI or HDBaseT Source’s Response to EDIDs
The 780D HDMI and HDBaseT IN ports emulate an HDMI or HDBaseT sink device. Part of that emulation
function is presenting an EDID to a source when a sink device is powered and hot plug is asserted. The 780D
is provisioned with a default EDID from the factory. There are two standard EDIDs available with the 780D as
provided: 1) Standard HDTV EDID, 2) Standard A/V Receiver EDID.
However you can reprovision the EDID by connecting it to a sink device whose EDID you would like to use for
testing. The 780D can store multiple EDIDs. These EDIDs can be obtained either by extracting them from an
HDMI or HDBaseT sink device (e.g. HDTV, Projector, AVR, repeater or distribution device input) or by
importing EDID .xml files created using Quantum Data EDID Editor tools. For procedures on importing EDIDs
refer to Adding Reference EDIDs for Use in Testing HDMI Devices.
The EDID test of an HDMI or HDBaseT source device enables you to see how a source device responds to a
specific EDID or a series of EDIDs. The EDID could be a known good EDID or an EDID you have chosen
specifically for testing purposes.
6.5.1
Configurations for Testing an HDMI Source Devices Response to an EDID
You can run this test in two configurations: 1) with your source device connected directly to the 780D, 2) with
your source device connected to the 780D through a repeater device. In both cases the 780D is emulating an
HDMI sink to test an upstream source. These configurations are shown below.
6.5.2
Configurations for Testing an HDBaseT Device’s Output Response to an EDID
Typically you run this test with the 780D connected to an HDMI source through an HDBaseT distribution
device. This configurations is shown below.

This section provides procedures for testing HDMI and HDBaseT cables, cable extenders, splitters, repeaters,
etc. The HDMI and HDBaseT Cable Test runs a pixel error test on the TMDS leads and a continuity check on
the 5V & hot plug leads and the DDC leads. The Repeater test runs a pixel error test on the TMDS leads and a
continuity check on the 5V & hot plug leads and the DDC leads but additionally tests the hot plug delay and the
hot plug width.
The cable test and repeater test can be used when the source and sink ends are collocated, in other words can
be connected to the 780D Tx and Rx ports. For a cable or distribution system that is installed and where the
source and sink ends cannot be connected to the 780D, you can use the Frame Compare feature. The Frame
Compare feature captures a reference frame and then compares a series of captured frames pixel by pixel to
the reference frame.

11 Running the Automated EDID Tests on HDMI Source Devices
This section provides procedures for running the optional Auto EDID test on HDMI source devices.
The HDMI Auto-EDID Test is included only if you have purchased the Auto EDID Test option.
11.1 HDMI Auto EDID Test
The Auto EDID Test enables you to verify that an HDMI source (or upstream HDMI network) properly handles a
series of EDIDs. The test checks the incoming timing against what is expected based on the contents of the
EDID such as the preferred timing. The test also verifies that the video parameters are consistent with the
capabilities of the EDID that is emulated. The 780D is configured with a set of EDIDs that it will emulate on its
HDMI Rx port. The EDIDs can be commercial EDIDs, test EDIDs or even known-bad EDIDs. The HDMI source
is connected to the HDMI Rx port and the test is initiated. The results are presented on the embedded screen.
As an option you can define a report for later viewing and dissemination to other colleagues and subject matter
experts.
11.1.1 Procedures for Configuring a Set of EDIDs for the Auto EDID Test
This subsection provides procedures for configuring the 780D with the desired set of EDIDs for testing. Note
that the test comes with a default set of EDIDs for running the test. However, typically you will want to create
your own set of test EDIDs. You will have to create a text file with the names (and descriptions) of the EDIDs
that you wish to use for testing.
Quantum Data offers an EDID Library free of charge which has a variety of EDIDs for use in testing. The EDID
Library provides details procedures on how to download and install EDIDs on a PC. The procedures below
assume that you have a set of EDIDs on your PC that you wish to use for the Auto EDID test. This procedure
also assumes that you have transferred those EDIDs into the EDID directory of the 780D. Refer to the section
in this manual Adding Reference EDIDs for Use in Testing HDMI Devices for instructions on transferring EDIDs
into the proper directory of the 780D.
9. Open up your favorite text editor program (example Notepad). Create a text file listing the EDIDs. Each
EDID listing in the file is structured as follows:
<name> <description>
Where name is the name of the EDID as it appears in the 780D file system and description is the name you
assign and appears in the Name field on the Auto EDID test results screen. The following is an example of
the text file:

12.3 Using Custom Bitmaps
You can import your own bitmaps into the 780D through the USB interface or load them from an SD card. Note
that when bitmaps are imported into the 780D, they are rendered at their native resolution, i.e. they do not
scale to the resolution of the video format you have selected as the standard test patterns do. Therefore, if you
want to test with a specific bitmap pattern for each resolution and you want the bitmap to fill the entire display,
you would need to import a separate bitmap of that image for each resolution you wish to test.
The 780D can accommodate up to 40 custom bitmap images in its internal memory and additional bitmaps
stored on the SD card.
Important Note: It is highly recommended that you not select bitmap images when outputting compressed
audio clips.
12.3.1 Workflow for Importing Bitmaps
In order to import and use bitmaps in the 780D you must take the following high level steps (detailed
procedures are provided further below):

Place the 780D’s USB interface in the Disk mode. This is not the default mode for the USB interface.

Create a text file called “UserPats.txt” that lists each bitmap stored for use. The name in the file has to
match the name of the bitmap. The procedures below provide an example of this text file.

Transfer the UserPats.txt file to the 780D over the USB interface.

Transfer the bitmap(s) over to the 780D flash memory through the USB interface.
12.3.2 Workflow for loading bitmaps from the SD card
In order to load bitmaps from the 780D’s SD card you must take the following high level steps (detailed
procedures are provided further below):

Create a text file called “UserPats.txt” that lists each bitmap stored for use. The name in the file has to
match the name of the bitmap. The procedures below provide an example of this text file.

Transfer the UserPats.txt file to the 780D to an SC card using a card reader.

Insert the SD card into the 780D SD slot on the front.
Important notes about SD card use and formatting:
1. The SD card (not an SDHC and not an SDXC).
2. The SD card should be a 1GB or less.
3. The SD card should be formatted using an SD format program available from www.sdcard.org.
4. The SD card must be formatted FAT16.

12.4 Creating Custom Menus
This section describes how to configure custom menus on the 780D. Custom menus enable you to display a
menu of commonly used functions on the 780D touch display. This allows you to save time by quickly executing
a specific set of resolution and image combinations.
The custom menus are setup using two text files that you create on your PC and transfer over to the 780D. The
two files are: 1) UserKeys.txt and 2) SeqMap.txt. The UserKeys.txt is a set of commands with menu key codes.
Each set of commands is a line in the text file.
12.4.1 To create a custom menu:
Use the following procedure to create a custom menu on your 780D.
1. Create a UserKeys.txt file or edit an existing file. An example of a UserKeys.txt file is shown below.
#F0
#F1
#F2
#F3
#F4
#FF
fmtl
fmtl
fmtl
fmtl
fmtl
mfgm
720p60;imgl user01;fmtu
1080p60;imgl pgcwrgb;fmtu
480p60;imgl smptebar;fmtu
dmt0660;imgl ramp;fmtu
1080i30;imgl focus;fmtu
0
Note that the commands are separated by a semicolon. In the example above in the first line there is a custom
bitmap image “user01” that is used.
2. Create a SeqMap.txt file or edit an existing file. An example of a SeqMap.txt file is shown below.
The SeqMap.txt then maps the commands listed in the UserKeys.txt file to a name and a location on the
custom menu. The following is an example of a SeqMap.txt file.
#F0
#F1
#F2
#F3
#F4
#FF
720p Master
1080p PGCWrgb
480p SMPTEbar
DMT0660 Ramp
1080i Focus
Go Home
The result of these two files would be the following custom menu:
Touch selecting the key labeled “1080p PGCWrgb” would cause the following command sequence to execute:
#F1 fmtl 1080p60;imgl pgcwrgb;fmtu
July 4, 2017
// loads 1080p60 format,
displays pgcwrgb test pattern

14 Using the Keypad
This section provides information and procedures for operating the 780D with a keypad. The 780D can support
keypad operation to enable efficient production test operation. An RS-232 numeric keypad is used for this
application. Supported keypad functions include selection of interface, timing, pattern, and test sequences.
14.1 Connecting a Keypad
A serial terminal keypad can be connected to the 780D front edge RS-232 connector.
14.2 Enabling and Configuring an RS-232 Keypad
The RS-232 keypad must be enabled and configured from the 780D Preferences menu. Use the following
procedures to enable a keypad.
1. From the 780D Home menu, select the Preferences tab. The Preferences menu will be displayed as
shown below.
2. Navigate to the second page using the More button.
July 4, 2017
Revision A8
780D HDMI Protocol Analyzer / Generator – User Guide
Page 243
3. For the RS-232 Keypad Mode menu item, select the ON button.
When selected, the ON button will be highlighted green.
4. Under RS-232 Baud Rate, use the arrow keys to select the correct baud rate for the keypad to be used.
For the Genovation keypad supplied by Quantum Data, choose 1200 baud. After selecting the correct baud
rate, power-cycle the 780D so that the changes take effect.
14.3 Keypad Functionality
For keypad support, the 780D uses four configuration files stored in the root directory of the internal flash. Here
are the names and functions of the four files:
 UserKeys.txt: This file provides mappings of key codes so that the 780D knows which key has been
pressed. This file may be different for each model of keypad that is used. This file should be configured by
Quantum Data Engineering, and should not be changed by the customer unless you wish to create a
specific test sequence. Procedures for creating a test sequence in the UserKeys.txt file are provided further
below. Please contact Quantum Data Applications Engineering if you need this file changed, or if you want
to use a different model of keypad.
 fmtmap.txt: This file provides mapping of format numbers to specific formats on specific interfaces. Each
interface has a range of format numbers associated with it, and these ranges are specified in file intmap.txt.
An example of the mapping for this file is depicted in Table 13-2.
 intmap.txt: This file specifies the ranges of format numbers assigned to each video interface. An example
of the mapping for this file is depicted in Table 13-3.
 imgmap.txt: This file provides a mapping of test pattern numbers to the actual test patterns. An example
of the mapping for this file is depicted in Table 13-4.
Keypad functions are assigned as shown in Table 13-1 below:

(repeat NEXT or PREVIOUS)
14.7 Programming a Test Sequence in the UserKeys file
You can also create a test sequence by including a set of commands in the UserKeys.txt file. The UserKeys.txt
file is primarily used internally for mapping the keypad keys to a set of commands for general keypad use.
However you can also use the UserKeys.txt file to store programming test sequences similar to macros.
The following is an example of a UserKeys.txt file which shows the keypad mapping and more importantly a
test sequence instruction set (#F0, #F1 and #FF). Note that there are two macro test sequences defined #F0
and #F1. The #FF definition is a macro that simply disables manufacturing mode in the 804 test instrument.
The #F0 macro also shows a special use case for the kbrd command. In this case the kbrd f0 command will
cause the macro to loop back on itself such that the #F0 macro continuously loops.
Note: Do not change any of the keypad mapping commands. These are the commands such as xkpm, xkpkj,
xkpu, xkpi. Modifying these commands will affect the general functions of the keypad.
