1 Introduction
The HDR Master 4K is a video processor converting SDR content into an HDR format. By analyzing the SDR
content and then intelligently filling in the missing information, the HDR Master 4K raises the dynamic range of
brightness, color gamut and color depth to HDR standard. With this all-round upgrade, the SDR video source
is converted into an HDR10 format that has a wider dynamic range of brightness, more colors and richer bright
and dark details.
The HDR Master 4K provides full 4K×2K@60Hz input and output connectors. Based on a pure hardware
system architecture, the HDR Master 4K allows for stable and highly-efficient processing capabilities, output
connector converting, SDI mosaic as well as long-distance optical fiber transmission.
Thanks to powerful capabilities of receiving a variety of video signals, ultra HD image processing and HDR10
image output, the HDR Master 4K can be widely used in applications such as high-end rental, stage control,
fine-pitch LED screens and video source conversion.

3 Applications
The HDR Master 4K supports the following three connection methods.
When a sending device is required, the sending device must be NovaStar’s independent controller or all-in-
one controller, such as NovaPro UHD, NovaPro UHD Jr and MCTRL 4K. When SDR to HDR converting
function is enabled on the HDR Master 4K, the HDR function on the sending device must be turned on at the
same time.
HDMI connection for short-distance transmission
Connect the HDMI output connector of the device to the sending device using an HDMI cable, and then
connect the sending device to the LED screen using Ethernet cables.
OPT connection for long-distance transmission
Connect the OPT ports of the device to the fiber converters using optical fiber cables, and then connect the
fiber converters to the LED screen using Ethernet cables.
SDI connection
One of the four SDI connectors is used for output, and the other three SDI connectors output the same
content synchronously. When the output is a 3G-SDI signal, SDI mosaic output is supported.

Connect the SDI output connectors to the sending device using SDI cables, and then connect the sending
device to the LED screen using Ethernet cables.
Note:
When SDR to HDR converting function is enabled, the HDMI output connector cannot be connected to a
monitor directly because the monitor does not support the playback of HDR content.
