4K/UHD Scaler
for HDBaseT™ and HDMI
Introduction
The Atlona AT-OME-RX31 is an HDBaseT receiver, three-input switcher, and 4K/UHD scaler with a local HDMI input.
Part of the Omega™ Series of integration products for modern AV communications and collaboration, the OME-RX31
features two HDBaseT inputs for receiving video up to 4K/60 4:2:0, plus embedded audio, control, and Ethernet over
distances up to 330 feet (100 meters). The HDMI input supports video up to UHD/60 4:4:4. The OME-RX31 is HDCP
2.2 compliant and features 4K/60 upscaling and downscaling with frame rate conversion. Additionally, it provides
integrated control for displays and room functions such as motorized screens, and can be externally triggered with
the addition of an occupancy sensor. The OME-RX31 is ideal for 4K presentation applications with Omega or UHDEX Series transmitters, as well as Atlona AV presentation switchers with HDBaseT outputs, local HDMI sources, and
the Gain™ Series ampliers.
Applications
• Complete system integration
The OME-RX31 and an Omega Series switcher / transmitter provide a compact, comprehensive, cost-eective,
and fully automated integration solution.
• Meeting rooms and conference rooms
The OME-RX31 can switch between AV from two transmitters below a meeting table, at separate wall locations,
or in two podiums. The HDMI input is ideal for a wireless collaboration gateway or digital signage.
• Active learning classrooms
In education applications, the OME-RX31 can be installed in a lectern and used to receive AV from two student
pods, each with an OME-ST31A below the table. Built-in 4K scaling optimizes content for the primary 4K or HD
display.

Key Features
Dual HDBaseT receiver with local HDMI input
• Three-input switcher with two HDBaseT inputs and an HDMI input.
• HDMI input is ideal for a wireless gateway, PC, video conferencing codec, or media player installed near a
display.
Video, audio, power, and data over category cable utilizing HDBaseT technology
• Receives up to 330 feet (100 meters) @ 1080p with CAT5e/6 or 4K/UHD using CAT6a/7 cable.
• Uses easy-to-integrate category cable for low-cost, reliable system installation.
4K/UHD downscaling and upscaling
• Preserves color and spatial detail when down-converting 4K content to 1080p or vice versa.
• Ideal for presentation applications where content is to be viewed on a variety of 4K and HD displays. Also ideal
for downscaling to 1080p for hardware VC codecs.
Automatic input selection and automatic display control
• Automatically changes display power state, and switches between inputs based on device connection or
disconnection from the switcher.
• Enables eortless, automated system operation without the need for an external control system.
Audio de-embedding
• De-embeds two channel PCM audio and delivers to a balanced, analog audio output.
• Independent volume and mute controls for embedded and de-embedded two-channel PCM audio, plus ve-
band EQ for the analog audio output.
Dual Ethernet ports and integrated network switch
• Allows a single connection to an AV LAN for IP control of a display and the OME-RX31 (plus transmitter or
switcher over HDBaseT).
• Simplify system design and integration with just one network drop for AV system control.
Contact closure for screen or display lift control
• Dry contact closure triggers electronic screen or lift operation based on active or standby mode of the
switcher / scaler.
• Automates screen or lift activation at system power-up; eliminates need for a separate AV control system.
Trigger I/O ports for occupancy sensing or remote button controls
• When used with an occupancy sensor, the switcher can be set to automatically go into standby, and power o
the display once participants have left the room.
• Greatly simplies user operation by avoiding the need to manually power up the system.
