Omni_InfoGraphicFinal-0516 Atlona this week launched OmniStream, its first line of networked AV products line that’s spec’d to allow 4K/UHD video, audio and RS232 control over Gigabit Ethernet.

Consisting of five products:

AT-OMNI-111 Single-Channel Networked AV Encoder
AT-OMNI-112 Dual-Channel Networked AV Encoder
AT-OMNI-121 Single-Channel Networked AV Decoder
AT-OMNI-122 Dual-Channel Networked AV Decoder
AT-OMNI-232 Dual-Channel Dante Networked Audio Interface

Atlona says that dual-channel encoding and decoding allows each AT-OMNI-112 and AT-OMNI-122 to process two independent 4K/UHD video streams (spec’d at either 4K@60Hz in 4:2:0 or 4K@30Hz in 4:4:4) a single, half-width rack enclosure. The dual-channel components can also be configured for system redundancy, with each encoder and decoder handling two simultaneous streams of the same HDMI source. The two independent streams are encoded and decoded simultaneously, and when a physical or logical connection fault is detected in a primary stream, the decoder automatically switches over to the back-up.

OmniStream features SMPTE VC-2 video compression (SMPTE 2042), claiming a lossless codec (9ms delay for 60 Hz video signals). And, OmniStream features SMPTE 2022 forward error correction for protection against packet loss and the resulting signal dropouts, which can occur in large-scale applications spanning several networks. It also features selectable AES-128 encryption for securing sensitive or protected content in government, military, healthcare, and corporate environments.

All OmniStream AV encoders stream HDMI embedded audio, including Dolby and DTS multi-channel bitstream formats. In addition, the AT-OMNI-232 Dante network interface can be used for transmitting and receiving two-channel audio over the network. The AT-OMNI-232 also integrates sources such as microphones and PCs into a third-party audio DSP as well as a larger Dante system. Advanced projects with a combination of OmniStream devices can be employed to simultaneously route AV-over-IP and Dante audio signals over the same network.

OmniStream devices can be powered using a PoE-equipped Gigabit switch as well as a dedicated power supply.

Atlona says the entire line will ship in September. Here are the details.
