The AT-OME-SR21 from Atlona is a high-performance unit which serves as a 4K/UHD scaler with a local HDMI input as well as an HDBaseT receiver. With the OME-SR21 belonging to the Omega™ Series of integration devices for advanced AV communications and collaboration, it accepts HDBaseT for video resolutions up to 4K/60 4:2:0, with control, Ethernet, USB and embedded audio up to a distance of 330 ft (100m). The HDMI input allows video resolution up to UHD/60 with 4:4:4 chroma subsampling. The unit is compliant with HDCP 2.2 and features upconversion and downconversion of 4K/60 which includes frame rate conversion. Also, it accepts Universal Serial Bus over HDBaseT and features a USB 2.0 hub for collaboration with cameras, microphones, PCs, speakers, Digital Signal Processors, as well as touch or interactive displays. The OME-SR21 is appropriate for applications of 4K presentation with Omega, UHD-EX or HDVS-200 Series transmitters, and also Atlona AV presentation switchers that include local HDMI sources, HDBaseT outputs, and the Gain™ Series amplifiers.

The OME-SR21 is a blend of the advantages of 4K/UHD scaling, auto-switching for HDMI and HDBaseT inputs, USB extension, integrated display control, and more. The unit can remotely switch an Atlona HDBaseT transmitter (Tx) through PoE. It has several favorite easy-to-use integration features while achieving outstanding performance and value for video conferencing and 4K presentation applications. For easy integration, the OME-SR21 has audio de-embedding features, integrated 2-port Ethernet switch, contact closure ports to effectively regulate a display lift or motorized screen, internal video test patterns for troubleshooting and setup, and remote management with Atlona Management System.


  • Whole system integration – The OME-SR21 as well as an OmegaSeries transmitter/switcher offer a portable, yet comprehensive and economic integration solution.
  • Larger system applications – The unit is appropriate for distributing AV and control, to a remote display from a switcher safely tucked in an equipment rack. With its included built-in 4K scaling, it optimizes content for High Definition and 4K displays.
  • Video conferencing – With a friendly Omega switcher/transmitter, Universal Serial Bus extension makes the OME-SR21 appropriate for the soft codec and web-based conferencing applications, which can unite with speakerphones, cameras, microphones, and Personal Computers.


HDBaseT receiver with local HDMI input

  • HDBaseT input receives AV, power, control, USB, and Ethernet up to 330 feet (100 meters) @ 1080p with CAT5e/6 or 4K/UHD using CAT6a/7 cable
  • HDMI input is ideal for a wireless gateway, PC, video conferencing codec, or media player installed near a display

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

USB 2.0 hub and extension over HDBaseT

  • USB type B interface for connection to a host PC, plus two USB type A ports for peripheral devices such as cameras, soundbars, or touch displays
  • Provides an ideal USB integration solution for software video conferencing and other applications

Audio de-embedding

  • De-embeds two channel PCM audio from any video source to a balanced, analog audio output
  • Independent volume and mute controls for embedded and de-embedded two-channel PCM audio, plus five-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-SR21 (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
