Introduction

Single-Channel Networked AV Decoder

Broadcast-grade, uncompromised 4K video over IP performance with nearly zero latency.

OmniStream delivers the highest quality 4K imagery using SMPTE VC-2 visually lossless compression (SMPTE 2042) with extremely low latency. VC-2 is optimized for video distribution over readily available Gigabit Ethernet infrastructure.

Fully scalable from rooms to campuses and enterprises. Imagine the possibilities.

AV over IP technology lets you realize opportunities for interconnecting AV throughout a facility, building, or across an entire corporate or university campus. Standard IP network hardware replaces the need for fixed matrix switching systems that are difficult to scale.

Built-in security and network error resilience.

OmniStream features selectable AES128 encryption for securing sensitive or protected AV content in government, healthcare, and other environments. OmniStream is also the only AV over IP platform in the industry with SMPTE 2022 forward error correction for ensuring robust performance over large network installations.

The Atlona OmniStream 121 (AT-OMNI-121) is a single-channel networked AV decoder for HDMI / HDCP 2.2 output supporting resolutions up to 4K @ 60 Hz and HDR (High Dynamic Range), plus audio embedding and de-embedding, and RS-232 or IR control pass-through. It is part of the OmniStream Pro Series, designed for high performance, flexible distribution of AV over standard, off-the-shelf Gigabit Ethernet switches in commercial audiovisual applications. It features advanced high-quality, VC-2 visually lossless video decoding technology with user-selectable, video quality optimization engines designed for computer-generated imaging, or motion video content. The Atlona OmniStream 121 achieves extremely low, sub-frame latency when paired with OmniStream AV encoders. This single-channel decoder is housed in a half-width rack enclosure with front-to-back air flow, and is ideal for high-density, compact installation in distributed, multi-display installations.

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.

Applications

• 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.
  
  
• 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.
  
  
• 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.
  

• Meeting rooms and conference rooms - An IP network infrastructure makes it simple and efficient to design AV systems for small, large, and divisible meeting room configurations, and to centrally manage them throughout a facility.
