Atlona has launched OmniStream, its first IP-based AV distribution line of networked AV products designed for integrating and distributing 4K/UHD video, audio and RS-232 control over Gigabit Ethernet networks employing off-the-shelf network switches.
Comprised of five products, the OmniStream line offers what the manufacturer is calling several ‘industry-first features’, including high density, dual-channel encoding and decoding, redundant AV networks and streams, encrypted content distribution, network error resilience, broadcast-quality 4K video compression with low latency and the ability to convey 4K video and Dante audio simultaneously over the same network.
The new line is particularly suited to interconnecting AV between multiple rooms and floors, over an entire building and across a corporate or university campus.
“We created OmniStream as an entirely new platform for dependable, high performance 4K video distribution over enterprise-wide network installations,” explains David Shamir, Atlona’s director of product management. “It redefines AV distribution over IP networks and addresses the many challenges of integrating and managing AV signal routing over Ethernet. It delivers the performance and reliability of traditional AV technologies and satisfies the technical demands of AV pros as well as IT managers.”
David says that OmniStream’s network-based approach enables virtually unlimited scalability and low-cost integration, which he says are benefits not available with conventional matrix switching technology.
The OmniStream line comprises the following 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
In what Atlona is calling an AV industry first, dual-channel encoding and decoding allows each AT-OMNI-112 and AT-OMNI-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 back-up.
OmniStream features SMPTE VC-2 video compression (SMPTE 2042), a visually lossless codec originally developed by the BBC for high quality imagery in master control video distribution as well as post-production and archiving.
According to the manufacturer, OmniStream delivers the lowest encode-to-decode latency of any pro AV industry codec, half a video frame or 9ms delay for 60Hz video signals, making it a smart choice for applications requiring tight audio and video synchronisation, such as live streaming.
OmniStream also 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 is designed with a host of essential features for streamlining and optimising AV integration. Decoders feature high performance 4K upscaling and downscaling with 4:4:4 video processing to preserve full colour integrity of computer-generated content. Decoders also can downmix multi-channel audio and deliver de-embedded two channel audio outputs. Automatic display control is available at the AV encoders through RS-232 and CEC. In addition, OmniStream offers the option to display a user-supplied logo, a full-screen image, or scrolling text.
To simplify system integration and minimise costs, OmniStream devices can be powered using a PoE-equipped Gigabit switch as well as a dedicated power supply. They also require Atlona Management System (AMS) software for configuration and control. AMS, available as a free download from Atlona, also serves as a centralised portal for managers or system administrators to monitor and manage an enterprise-wide OmniStream system.
All OmniStream products will be available September 2016.
