OG-4K2HD 4K/UltraHD-SDI to 3G-SDI Down-Converter v1.0 3 www.aja.com
Chapter 1 – Introduction
Overview
OG-4K2HD is an openGear card that down-converts professional 3G-SDI 4K/
UltraHD signals to HD resolution using AJA’s high-quality scaling for cost-effective
monitoring and conversion. OG-4K2HD’s HD-SDI and HDMI outputs are live
simultaneously, producing fantastic-looking HD images for on set monitoring or
direct-to-air broadcast.
OG-4K2HD supports high frame rate (HFR) 4K/UltraHD inputs at 50 and 60fps
and converts to HD outputs at 50 and 60fps for accurate viewing. OG-4K2HD’s
configuration options allow extraction of an HD resolution image from the 4K
input to provide a one-to-one pixel image for 4K focus checks on HD displays.
Designed for use in high-density openGear’s 2RU frames including AJA’s OG-X-FR
2RU frame, new DashBoard Software support on Windows®, macOS® and Linux®
offers remote control and monitoring of the openGear architecture and provides
convenient and industry-standard configuration, monitoring and control options
over a PC or local network.
OG-4K2HD Operating Modes
OG-4K2HD has three working modes: 4K Down-Conversion mode, Non-4K mode,
and Center Cut mode. The first two modes are selected automatically depending
on the input video. These modes can also be manually set using the DashBoard
application.
• 4K Down Conversion mode: If the format of the input video is detected as 4K
or UltraHD format, or the unit is congured by DashBoard, 4K/UltraHD input
video is down-scaled to 2K/HD video and then output on both the HDMI and
the SDI outputs.
• Non-4K mode: If the format of the input video is detected as a non-4K video
source, for example, 720p60, OG-4K2HD will output video that matches the
signal format and resolution of the input signal.
• Center Cut mode: OG-4K2HD will be in Center Cut mode if the input video
is 4K/UltraHD format, and the mode has been enabled through DashBoard.
In this mode the 2K/HD center of 4K/UltraHD input video will be output to
the HDMI and SDI outputs. No down-scaling occurs, and the output format
is either 1920x1080 or 2048x1080 (depending the input source and the 2K
cropping conguration).
OG-4K2HD 4K/UltraHD-SDI to 3G-SDI Down-Converter v1.0 4 www.aja.com
Default Operation
The OG-4K2HD auto configures to the connected inputs.
The auto-configure function identifies the connected inputs and generates the
default outputs for the given input. Default operation can be overridden and set
manually using AJA’s DashBoard application.
NOTE: Signal conversion requires the presence of a valid SDI video signal on the SDI IN 1
BNC.
For single SD or HD inputs, BNC input 1 is the default input. For dual-link 1.5Gb
HD inputs, and 4K/UltraHD dual-stream 3Gb SDI inputs, inputs 1 and 2 are
default. Where applicable, both level A and B 3Gb inputs are auto-detected and
supported.
When connecting the OG-4K2HD with multiple SDI inputs in the auto-configure
mode (default), as the user connects the first HD-SDI to input 1, the unit will
output that input as a full screen HD. As soon as the second input is connected,
the unit will know that either QuadHD or 4K x 2160 is present and the display will
change to show the two connected quadrants in the upper left and upper right of
the output. The remaining two quadrants will be displayed as they are connected.
It is possible to use two dual-stream 3G inputs to make 3840 or 4K video. In this
case SDI1 and SDI2 are assumed to be the inputs: SDI1 linkA makes the top left
quadrant, SDI1 linkB makes the top right quadrant, SDI2 linkA makes the lower
left quadrant, and SDI2 linkB makes the lower right quadrant. To use this mode
change the Video Source Selection to ‘2 X SDI 4K’.
Video Output
OG-4K2HD has two output connectors, HDMI and SDI, that are both active
simultaneously.
For 4096x2160 inputs, the OG-4K2HD will output 2048x1080 if 2K crop option is
turned off (through DashBoard), otherwise 4096x2160 inputs will be scaled to
2048x1080, then cropped to 1920x1080. OG-4K2HD will not scale 4096 to 1920
pixels.
The HDMI and SDI output connectors will generally be the same video, with the
exception of non-4K PsF video input.
SDI passthrough is enabled by default if the input video is 2K/HD PsF. In this
case, SDI output is PsF format, and HDMI output is progressive format. The HDMI
output is delayed one frame, compared to the SDI output. The SDI passthrough
can be disabled by DashBoard. If disabled, the SDI output will be progressive
format, the same as HDMI output, with no frame delay.
HDMI and SDI Output Control Differences
Some video output control options are only applicable to HDMI output, such
as color range, sample structure or HDMI/DVI standard. Some options are only
applicable to SDI output, such as Level B control, or PsF passthrough. And some
output control options are applied to both, such as Center Cut.
DashBoard Control
Configuration set via DashBoard is stored in the OG-4K2HD unit through
subsequent power cycles.

Signal Indicators on the OG-4K2HD Card
Located at the upper front area of the OG-4K2HD card, the SD Lock and HD Lock
LEDs work in combination to indicate the type of signal detected for each SDI
input.

User Controls
The OG-4K2HD can be used right out of the box for many applications, since
it is designed to recognize inputs and perform standard actions automatically.
However, you can also manually configure the OG-4K2HD using remote
conguration through the DashBoard Control System for an openGear Frame.
DashBoard Control System
The DashBoard Control System, created by Ross Video, provides a control
interface between Windows, macOS and Linux computers and the cards installed
in an openGear frame. DashBoard operates through TCP/IP communication
and requires an Ethernet connection between the controlling computer and an
openGear frame.
For details about acquiring and using the DashBoard Control System, refer to
"Using the DashBoard Control System" on page 13.

Front OG-4K2HD Card Installation
1. Open the openGear frame door as follows:
A. Gently pull the side door tabs towards the center of the door, releasing the
door from the frame.
OG-4K2HD 4K/UltraHD-SDI to 3G-SDI Down-Converter v1.0 11 www.aja.com
B. Using both hands, pull the door towards you. The door extender arms
prevent the door from falling.
2. Locate the Rear Card you installed as described above. The interior slot
number is dependent on the slot combinations into which you installed the
Rear Card. This allows adequate spacing to avoid damaging the card, the
cards installed in the neighboring slots, or both.
3. Hold the card by the edges and carefully align the card edges with the rails
inside the frame. The slots are numbered starting from the left-most slot
when facing the fame front.
IM PORTA NT: OG-4K2HD cards are installed into the right (even numbered) slot of the pair
in order to connect with the rear panel.
4. Fully insert the card into the frame until the card is properly seated in the
Rear Card.
