Atlona® OmniStream™ Single-Channel Networked AV Decoder

Add to cart

The Atlona® OmniStream™ 121 is a single-channel networked AV decoder for HDMI 2.0 / 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.

Atlona® OmniStream™ Single-Channel Networked AV Decoder

The Atlona® OmniStream™ 121 is a single-channel networked AV decoder for HDMI 2.0 / 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.

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.
