    AT-OMNI-121 - Overview

    The Atlona OmniStream™ 121 (AT-OMNI-121) is a networked AV decoder for an OmniStream-encoded video stream 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 121 is HDCP 2.2 compliant and ideal for the latest as well as emerging UHD and HDR displays. It features visually lossless compression for critical-quality video and graphics applications, with extremely low, sub-frame latency from encode to decode. Also included are selectable AES-128 encryption, and SMPTE 2042 forward error correction for robust AV distribution spanning multiple networks. Additionally, this decoder features high performance upscaling and downscaling, aspect ratio control, video wall processing, multi-channel PCM audio downmixing, audio embedding and de-embedding, plus presentation enhancement features such as logo insertion and scrolling on-screen text. The OmniStream 121 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 121 is compatible with the OmniStream 111 and OmniStream 112 encoders, and the OmniStream 232 Dante networked audio interface.


  • 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.)
