FS-HDR
Quick Start Guide
Overview
FS-HDR, a 1RU, rack-mount, universal converter/frame synchronizer, is designed
specifically to meet the HDR (High Dynamic Range) and WCG (Wide Color Gamut)
needs of broadcast, OTT, post and live event AV environments, where real time,
low-latency processing and color fidelity is required for 4K/UltraHD and 2K/HD
workflows. Developed in partnership with Colorfront, the FS-HDR’s HDR/WCG
functionality is powered by Colorfront Engine™ proprietary video processing
algorithms. FS-HDR also serves as a full, 1-channel up, down, cross-converter for
4K/UltraHD/2K/HD conversion and frame sync needs and in 4-Channel mode,
offers 4 independent channels of 2K/HD conversion.
Quick Start Guide Objectives
The FS-HDR can be extremely simple to use, because of its ability to detect
incoming signal formats and automatically apply the correct video processing for
the selected output format. However, the FS-HDR is also extremely powerful and
can be flexibly configured to perform a wide variety of tasks.
This Quick Start Guide is designed to help you get your FS-HDR up and running
for the first time, and confirm it is operating properly. It also provides step-by-
step instructions that demonstrate a few FS-HDR signal processing examples.

HDR and WCG Background
High Dynamic Range (HDR) and Wide Color Gamut (WCG) are relatively new ways
to present video programming that gives brighter highlights, more detailed
shadows, and enhanced colors with smoother gradients. HDR and WCG are
display oriented features, dependent on the capabilities of the device presenting
the video material.
Standards have been developed to help manage HDR signal flows, including:
• HDR-10 (for HDMI) - Uses a Perceptual Quantizer (PQ) curve that accounts for
the human visual response to maximize coding eciency. This standard also
uses static metadata to communicate signal characteristics to the monitor so
it can optimize its display characteristics to match the signal.
• Hybrid Log Gamma (HLG) - Uses a combination log and gamma curve to
achieve coding eciency of HDR signals while also allowing the same signal
to be shown on both standard and HDR displays. No metadata is required.
Other standards exist, or are in development, including some that have dynamic
metadata, which can be used by displays to adjust for the best possible picture
from scene to scene.

Stand Alone Tests
The stand alone tests can be performed without a computer, using the FS-HDR
front panel controls and rear connections. The following procedures assume
the FS-HDR is at factory defaults (taken from a newly opened box). If not set to
defaults, the FS-HDR may behave differently.
NOTE: FS-HDR units are configured at the factory to operate in Four Channel Mode.
First Power Up
The following workflow powers up a default FS-HDR and demonstrates some
example alarms.
Setup
• Ensure the FS-HDR is completely disconnected (all video, audio, network, and
power connector ports are empty).
Procedure
1. Connect both FS-HDR power cords to mains AC and allow time for the unit
to boot up. Observe the front panel LEDs.
• The REF LED will light red, indicating an alarm condition. By default the
FS-HDR is congured to operate genlocked to an external reference signal.
2. Press the front panel STATUS button, then turn the SELECT knob to view
various Status menus.
• The Status menu for Video Processor 1 will report No Input for IN1, the
port is disconnected), and the GEN (Genlock) parameter will report Ref
(congured for external reference) but will also report No Input.
Video Format Status screen Video Format Alarm Status screen
IN1 SDI 1 No Input
BKGD Black 1080i59
GEN Ref No Input
OUT1 1080i59
IN1 SDI 1 OK
BKGD Black OK
GEN Ref No Ref
Rate 59/29/23
3. Connect a 1080i59.94 HD tri-level sync reference signal to one of the FS-HDR
Ref Loop BNCs, and connect a 75 ohm terminator to the other Ref BNC.
• The REF LED will light blue, indicating the FS-HDR is genlocked to an
external reference signal.
• The Status menu GEN parameters will report Ref and indicate the format of
the incoming reference signal or OK.
• However, because the FS-HDR is still not receiving a compatible video input,
No Input, will be reported for IN1.

5. Disconnect one of the power cords, leaving the other attached.
• The front panel PWR LED will light red for the power supply with the
removed cord.
• The PS status will report PS1 (or 2) OFF
6. Reconnect the power cable. The PWR LED for that power supply will light
blue and the power supply status will report OK.
This workflow confirms the FS-HDR powers up successfully and reports reference
and power supply alarms.
NOTE: FS-HDR Reference, Power Supply, and Video Format alarms can be disabled, if
desired. This will prevent the LEDs from going red, but will not affect front panel
status displays.
Internal Test Signals
This workflow generates bars and tone and routes them to an FS-HDR video and
audio output. This example uses the SDI 1 and AES output connectors, an SDI
video monitor, and an AES audio monitor.
NOTE: In the following procedures, where the terms select and adjust are used, turn the
front panel SELECT and ADJUST knobs.
Setup
• Connect the FS-HDR SDI 1 output BNC connector to an SDI video display with
a BNC cable.
• Connect the FS-HDR AES/EBU output DB25 connector to an AES audio
monitor using a standard TASCAM pinout cable (customer supplied). Separate
DB25 connectors carry all 8 AES digital audio pairs (16 audio signals), one
connector for input and one for output. Turn the output gain of the audio
monitor to a low level.
Procedure
1. Press the VID1 Channel Select button.
2. Press the FORMAT Video button
• Select 1 Output Format and adjust to a signal compatible with your SDI
monitor (for example, 1080i59.95).
3. Press the TSTGEN Video button.
• Select 1 Test Pattern Gen and adjust to On.
• Select 2 Test Pattern and adjust to 75% Bars.
4. Press the AES Channel Select button.
5. Press the MAP Audio button.
• Select 1.0 AES Out and adjust to Sig Gen 400KHz.
You should now be able to see the test signal on the SDI Monitor display, and hear
the audio on the AES monitor.
This workflow confirms the FS-HDR generates and outputs video and audio.

FS-HDR Quick Start Guide v1.0 6 www.aja.com
FS-HDR Network Setup
The following instructions summarize ways to configure the FS-HDR to
communicate with a computer directly or over a network.
Networking Using DHCP or Default Static IP
The FS-HDR factory default configuration automatically looks for a DHCP server
to issue an IP address. If your network includes a DHCP server, plug the FS-HDR
into the network and connect with the unit as follows:
1. Press the CONFIG button.
2. Turn the SELECT knob to navigate to the Status menu that has the name of
the FS-HDR at the top (default is “aja-FS-HDR”). Note the DHCP-supplied IP
address shown.
3. With your laptop or desktop computer connected to the same LAN as the
FS-HDR and DHCP enabled, type the IP address you noted on the FS-HDR’s
display into the browser address eld and press Enter. You should now see
the FS-HDR’s browser Status screen.
If the FS-HDR cannot get an address from the network DHCP server, the FS-HDR
will automatically use a preset factory static IP address of 192.168.0.2. You can
access the FS-HDR using the default static address as follows:
1. Set your computer’s IP address to whatever address you prefer in the
192.168.0 (classC) network.
2. Set the computer’s Subnet mask to 255.255.255.0 (most PCs default to the
proper netmask when the address is set).
3. Set the gateway address, if used, to match the FS-HDR default: 192.168.0.1.
Alternatively, change the FS-HDR gateway address to match your gateway:
A. Press CONFIG, turn SELECT to 3.4 Default Gateway, push and then turn
ADJUST to change the rst group of digits.
B. Turn SELECT to advance to the next set of numbers, and turn ADJUST to set
these numbers.
C. Continue using SELECT and ADJUST to set the full address.
D. When nished, push ADJUST momentarily to save the address.
5. Run a browser on the computer and type “192.168.0.2” (the factory static IP
address). You should now see the FS-HDR’s browser status screen.
Networking the FS-HDR Using Your Own Static IP
If you don’t want to use DHCP or the default static IP address, you can set your
own static IP address:
1. Select the CONFIG button and use the SELECT knob to navigate to
parameter 3.1 IP CONFIG. Use the ADJUST knob to select Static.
2. Turn SELECT to navigate to parameter 3.2 IP ADDRESS. The display shows
the default static IP address: 192.168.0.2.
3. Change the IP address as follows.
A. Push the ADJUST knob momentarily so that the rst octet (set of numbers)
blinks, and then turn ADJUST to change the numbers.
B. Turn SELECT to advance to the next set of numbers, and turn ADJUST to set
these numbers.
C. Continue using SELECT and ADJUST to set the full address.
D. When nished, push ADJUST momentarily to save the address.

FS-HDR Quick Start Guide v1.0 7 www.aja.com
5. Turn SELECT to advance to 3.3 Subnet Mask. Use the SELECT and ADJUST
knobs as in the previous step to set the desired subnet mask.
6. Turn SELECT to advance to 3.4 Default Gateway. Use the SELECT and ADJUST
knobs as in the previous step to set the desired gateway address.
7. Run a browser on the computer and type in the IP address you set for the
FS-HDR. You should now see the FS-HDR’s Status screen.

FS-HDR Quick Start Guide v1.0 8 www.aja.com
Sub-Menus
Some parameters, when activated, open sub-menus. The sub-menus are a lighter
gray color and have a collapse/expand button on the parent selection. This
lets you collapse the sub-menus for easier system configuration. The collapsed
setting only stays in effect until the user reconnects or refreshes the browser.
FS-HDR Processing Examples
In the following procedures, your exact actions depend on which FS-HDR
interface you are using. Where the terms MENU NAME, select and adjust are used:
• On the front panel interface, press the indicated Menu Group Selection
button and then turn the SELECT and ADJUST knobs to choose the parameter
and change the setting. The Front Panel menu numbers are included in the
procedures.
• On the web browser interface, use your mouse to select the name of the Menu
Screen and then choose the parameter and setting using the drop down list or
slider. Menu numbers are not present on the FS-HDR web pages.
About FS-HDR Operating Modes
The FS-HDR has two operating modes.
• Single Channel Mode (4K/UHD) has one video processing channel capable of
4K/UltraHD video, and supports up & down-conversion to and from HD video.
• 4 Channel Mode (HD/SD) has four video processing channels capable of
HD video, and each channel supports independent up & down-conversion
between HD and SD video.
Both operating modes support various types of High Dynamic Range (HDR) and
Wide Color Gamut (WCG) video, and can perform conversions between them.
The appropriate FS-HDR operating mode should be selected first, because
parameter setting changes only affect the current operating mode.
To change the FS-HDR operating mode:
1. Press the CONFIG System button:
2. Select 2 FS-HDR Mode
3. Select either 4K/UHD or HD/SD and press ADJUST.
NOTE: The FS-HDR must restart after its operating mode has been changed.
FS-HDR Processing Examples
General FS-HDR Setup

The Dynamic Range Clamp parameter can be used to quickly preview what an
HDR signal may look like on an SDR monitor, without having to switch between
HDR and SDR modes on that monitor (which may go black during the change-
over). The FS-HDR default setting is No Clamp, and this generally should be used
during production. When set to 100 Nits, the HDR signal is cleanly compressed to
SDR, allowing quick A/B comparison on an HDR display in HDR mode.
NOTE: The Dynamic Range Clamp parameter is only active when PQ BT.2020 1000 Nits
or Hybrid Log Gamma BT.2100 HDR video is being output.
Additional Settings
Other more specialized settings not discussed in the Quick Start Guide may also
apply to your workflow. Refer to the FS-HDR Installation and Operation Guide
available on the AJA website for more information.

Multiple Legacy Device SDR To HDR Live Conversion
The following workflow demonstrates simultaneously converting multiple legacy
device SD and HD signals for an HD HDR production. In this example, signals
from two legacy SDR HD cameras, a legacy SD Video Replay system, and a legacy
SD Character Generator are up-converted or transformed to HLG for a live HDR
production. Four Channel mode operation is required.

Setup
• Ensure the FS-HDR is receiving a valid reference signal. Connect a 1080i59.94
HD tri-level sync signal to one of the Ref Loop BNC connectors, and terminate
the other Ref Loop BNC connector.
• Congure the source devices to the desired settings and connect them to SDI1
through SDI 4 BNC inputs on the rear of the FS-HDR. Once connected the LED
below the VID1 button on the FS-HDR front panel will light.
• Connect the FS-HDR SDI1 through SDI4 BNC output connectors to a HDR
compatible video switcher.
• Ensure the FS-HDR Vid (n) FORMAT 2.2 Dynamic Range Clamp parameter is set
to No Clamp (default).
• View the FS-HDR SDI output signal on a compatible HDR display.
Procedure
System Configuration
1. If the FS-HDR is not already in Four Channel Mode, press the CONFIG System
button:
• Select 2 FS-HDR Mode, select HD/SD and press the ADJUST knob. Wait for the
FS-HDR to reboot (not longer than 90 seconds).
2. Press the VIDEO System button.
• Select 1 Output Frame Rate, and adjust to 59/29/23.
• Select 2 Genlock Source, and adjust to Reference.

5. Press the FORMAT Video button.
• Select 1 Output Format, and adjust to 1080p5994.
• Select 2.1 Dynamic Range&Gamut, and select Hybrid Log Gamma BT.2100.
6. Press the INPUT Video button
• Select 2.2 SDR Highlights and select for best image from: Standard (default),
Soft 1-3, or Bright.
NOTE: The SDR Highlights parameter is only active when transforming from SDR to
HDR. Source SDR video dynamic range compression can vary, and only be visible
when expanded to HDR. This parameter offers five different presets that can be
used to try to match the source material. For lesser quality SDR video that exhibits
substantial clipping, a less aggressive expansion is a better choice. The Soft 1 to 3
settings are progressively less aggressive.
7. If you have optional SFP output modules installed, you can select FORMAT
3.0 Link Cfg SDI5 and adjust to Sngl Lnk LvlA for an additional copy of that
converted signal.
Video Processor 2, 3, and 4 Setup
8. Press the VID2, 3 or 4 Channel Select button.
9. Repeat the Video Processor 1 setup steps described above, substituting 2/6,
3/7, and 4/8 as appropriate.
The video switcher should now be able to accept all the converted to HLG signals.
Multiple Simultaneous HDR and SDR Distribution
The following workflow demonstrates simultaneously distributing HDR and SDR
content. In this example, the FS-HDR converts one HDR input to a different HDR
format output and also converts it to an SDR output. Simultaneously the FS-HDR
also converts two other signals, one from a BNC input, and the other from an SFP
module input. Four Channel mode operation is required.
