The Atlona OmniStream product line is their first foray into the its first line of AV-over-IP products. The OmniStream family consists of five products to integrate and distribute 4K/UHD video (@60Hz 4:2:0 Chroma Sub-sampling), audio, and RS-232 control over Gigabit Ethernet networks — albeit compressed. The OmniStream line has dual-channel encoding and decoding, redundant AV networks and streams, encrypted content distribution, broadcast-quality 4K video compression (if you consider compression broadcast-quality) with low latency and the ability to convey 4K video and Dante audio simultaneously over the same network.
The OmniStream line comprises the following products:
- OmniStream 111 (AT-OMNI-111) Single-Channel Networked AV Encoder
- OmniStream 112 (AT-OMNI-112) Two-Channel Networked AV Encoder
- OmniStream 121 (AT-OMNI-121) Single-Channel Networked AV Decoder
- OmniStream 122 (AT-OMNI-122) Two-Channel Networked AV Decoder
- OmniStream 232 (AT-OMNI-232) Two-Channel Dante Networked Audio Interface
From hat we can tell, this is the first AV-over-IP product that has dual-channel encoding and decoding — this allows each OmniStream 112 and OmniStream 122 to process two independent 4K/UHD video streams in 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 backup.
OmniStream uses SMPTE VC-2 video compression (SMPTE 2042), a visually lossless codec that Atlona says was originally developed by the BBC for high quality imagery in master control video distribution as well as post-production and archiving — the delay is a half a video frame or 9 millisecond delay for 60 Hz video signals.
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 OmniStream 232 Dante network interface can be used for transmitting and receiving two-channel audio over the network. The OmniStream 232 also integrates sources such as microphones and PCs into a third-party audio DSP as well as a larger Dante system.
