4K2HD Mini-Converter v1.15r1 4 www.aja.com
Chapter 1 – Introduction
Overview
AJA’s 4K2HD downconverts professional SDI 4K/UltraHD signals to HD resolution
using AJA’s high-quality scaling for cost-effective monitoring and conversion.
4K2HD’s HD-SDI and HDMI outputs are both live all the time, producing fantastic-
looking HD images for on set monitoring or direct-to-air broadcast. 4K2HD
supports high frame rate (HFR) 4K/UltraHD inputs at 50/59.94/60fps and converts
the 2K/HD output to 50/59.94/60fps for accurate viewing. 4K2HD’s configuration
options can extract a 2K/HD resolution image from the 4K/UltraHD input to
provide a one-to-one pixel image for 4K/UltraHD focus checks on 2K/HD displays.
Configuration can be set remotely via AJA Mini-Config software control over USB.
4K2HD Operating Modes
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 Mini-Config
application.
• 4K Down Conversion mode: If the format of the input video is detected as 4K
or UltraHD format, or the unit is congured by Mini-Cong, 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 input video is detected as non-4K video
source, e.g. 720p60, or the unit is congured by Mini-Cong, 4K2HD will not
try to make 4K/UltraHD video from four video inputs. Instead, it will output
video to HDMI/SDI from the selected SDI input.
• Center Cut mode: 4K2HD will be in Center Cut mode if the input video is 4K/
UltraHD format, and the mode has been enabled through Mini-Cong. 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
conguration).
4K2HD Mini-Converter v1.15r1 5 www.aja.com
Default Operation
The 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 Mini-Config 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 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
4K2HD has two output connectors, HDMI and SDI, that are both active
simultaneously.
For 4096x2160 inputs, the 4K2HD will output 2048x1080 if 2K crop option is
turned off (through Mini-Config), otherwise 4096x2160 inputs will be scaled to
2048x1080, then cropped to 1920x1080. 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 Mini-Config. If disabled, the SDI output will be progressive
format, the same as HDMI output, with no frame delay.
The HDMI and SDI outputs are turned off when no active SDI Input signal is
detected, allowing connected displays to go on Standby/Sleep mode.
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.
Mini-Config Control
Configuration set via Mini-Config is stored in the 4K2HD unit through subsequent
power cycles.

4K2HD Mini-Converter v1.15r1 16 www.aja.com
Output Mode
4K Convert
• Downconvert - Downconverts incoming 4K signal to HD (default setting).
• Center Cut - Selects the center portion of the incoming 4K signal for display.
No down-scaling occurs, and the output format is either 1920x1080 or
2048x1080 (depending the input source and the 2K Crop setting.
2K Crop
Choose On or Off. Provides the option of center cutting 2Kx1080 video signals to
make 1920x1080, or center cutting a 4Kx2160 signal to make 1920x1080. Default
is On.
Edge Filtering
Choose On or Off. You can disable edge filtering with this control. This is useful
if you are stitching together multiple images of 4K2HD outputs. An example is
using four 4K2HD’s to view UHD-2 or 8K on a UltraHD/4K or HD monitor. Each
4K2HD downconverts one quarter of the 8K image. Disabling edge filtering can
eliminate the center vertical and horizontal lines that would occur between the
quadrants in that situation. Default setting is On.
SDI Out
Passthrough
Choose Auto, Off, or On (default is Auto). This setting can be used with HD or 2K
psf format input signals. When On, psf format will passthrough to the SDI output
instead of the converted, progressive format signal.
3Gb Mode
Choose Auto, 3G-A, or 3G-B (default is Auto).
Progressive to Interlace Enable
Progressive to Interlace Enable. Choose Off or On. When On, a 4K/UHD
progressive input will be output as a 1920x1080 interlace signal when possible.
More specifically, when Progressive to Interlace is enabled, the 4K2HD converts
4096x2160 or 3840x2160 progressive signals to a 1920x1080 interlace signal. Crop
is automatically applied if the input signal is 4K.
This conversion is functional for the 4K and UHD input formats listed below:

Audio Screen
Click on the Audio tab to view and make changes to the 4K2HD audio settings.
Input Source
Choose which embedded audio channels are routed to the HDMI output. Eight
channels are routed at a time. You can choose Ch 1-8 or Ch 9-16 from any SDI
input.
HDMI Channel Count
Choose Auto, 2 of 8 channels or 8-channels embedded audio. Choosing “Auto”
automatically selects the audio channels based on the attached device’s
capabilities.
The SDI output embedded audio always follows the selected HDMI Output source
selection and is limited to 8 channels max.
Audio Offset In Frames
Permits time shifting the embedded audio in relationship to the video (for
example, to correct for lip sync problems), in 1/16 of a frame increments. Range is
from -0.8125 video frame to +7.0 video frames. The actual time duration of delay
will vary depending on the frame rate of the format being converted.
Default offset value is 0 frame to match the video delay path, resulting in time-
aligned audio on the output. Positive offset delays the audio additional frames
(relative to the video output), negative offset advances the audio relative to the
video output.

Update Screen
Use this Update screen to view the software version currently installed on the

NOTE: When discussing Mini-Converters, “Firmware” is software that will be stored in
the Mini-Converter’s non-volatile memory and used when it is powered up. This
is something different than the Mini-Config application software. The version
numbers shown in the Update screen refer only to the firmware.
Installed
This field shows the version of the firmware currently installed inside the Mini-
Converter.
Desired
This field shows the version of firmware embedded in the Mini-Config application
which you can install into the Mini-Converter by clicking the Update button.
Update
This button initiates a software update operation loading the “Desired” version of
firmware into the Mini-Converter’s non-volatile memory.
Progress
This indicator bar shows the progress of firmware installation.
Software Update Procedure
