    AT-OMNI-111 - Overview

    The Atlona OmniStream™ 111 (AT-OMNI-111) is a networked AV encoder for one HDMI source up to UHD @ 60 Hz and HDR, plus embedded audio and RS-232 or IR control pass-through. It is part of the OmniStream Pro Series, designed for high performance, scalable distribution of AV over Gigabit Ethernet in commercial applications. The OmniStream 111 is HDCP 2.2 compliant and ideal for the latest as well as emerging UHD and HDR sources. It features visually lossless compression for critical-quality video and graphics applications, with extremely low, sub-frame latency from encode to decode. The OmniStream 111 also includes selectable AES-128 encryption, and SMPTE 2042 forward error correction for robust AV distribution spanning multiple networks. This encoder is housed in a half-rack width enclosure. The OmniStream 111 can conveniently be powered over the network through Power over Ethernet (PoE), as well as from local AC power.

    Easy to Configure, Simple to Manage
    OmniStream AV over IP systems are remarkably easy to set up and manage - whether for a meeting room, residence, divisible room, or an entire university campus. Atlona Management System (AMS) 2.0 features automatic network device discovery, plus an intuitive web-based GUI that lets you configure virtual routing for AV, control, and data over the network - just as easily as you would with conventional AV matrix switching. AMS also streamlines and simplifies management of OmniStream systems through continuous system monitoring, notifications and alerts, event logging, multi-device configuration and backup, automated firmware updates, remote device control, and more.

    Product Compatibility
    The OmniStream 111 is compatible with the OmniStream 121 and OmniStream 122 decoders.


  • Enterprises and other large organizations - Maximize AV application flexibility by enabling content sharing within single meeting rooms, or corporate-wide broadcasting to every connected screen. (See this featured application as an example.
  • Corporate and university campuses with the need to distribute AV between buildings - OmniStream allows virtually unlimited AV system scope and scale. For very large, expansive LANs, SMPTE-standard FEC (forward error correction) ensures robust, reliable image presentation at every endpoint. (See this featured application as an example.)
  • Applications in which any AV content or resource can be shared anywhere in the system - AV over IP technology removes the restrictions associated with interconnecting sources and displays through standard matrix switching architecture.
