Dual-Channel Networked AV Encoder




  • Best-in-class AV over IP performance and reliability over Gigabit Ethernet
  • Dual-channel AV encoder for HDMI® up to 4K/UHD, plus embedded audio and RS-232 or IR control pass-through
  • Networked AV redundancy
  • Supports UHD @ 60 Hz plus HDR formats
  • Network error resilience with FEC (forward error correction)
  • Simplify integration with plug-and-play network switch compatibility
  • Local or PoE (Power over Ethernet) powering
  • Industry-standard, network security features including IEEE 802.1x
  • Automatic HDMI input switching


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.
