Unsurpassed AV over IP Performance and Reliability over Gigabit Ethernet

Artifact-free graphics and video

OmniStream™ is powered by the advanced VCx codec which delivers 4K/60 4:4:4 from encode to decode, with pristine-quality presentation of computer-generated and fast-motion video content.

Ultra-fast switching

A user can switch between video streams up to 4K/60 from OmniStream AV encoders with less than a half-second transition. Fast switching works between video streams at different resolutions and frame rates.

Designed for system expansion

The VCx codec is highly efficient, allowing numerous 4K and 1080p streams over 10 Gigabit uplinks between network switches. This is a powerful advantage when
designing systems for scalability.

Two AV encoders in one

The OMNI-112 features two channels of encoding in a single box. This enables high-density equipment installations in racks, saving valuable space while allowing units to be stacked due to front-to-back air cooling.

Details

The Atlona AT-OMNI-112 is a networked AV encoder with two independent channels of encoding for two HDMI sources up to 4K/60 4:4:4 and HDR (High Dynamic Range), plus embedded audio and RS-232 or IR control pass-through. OmniStream is designed for high performance, flexible distribution of AV over standard, off-the-shelf Gigabit Ethernet switches in commercial audiovisual applications. The OMNI-112 features the advanced VCx™ codec which delivers 4K/60 4:4:4 video from encode to decode, with artifact-free presentation of computer-generated content and fast-motion video, and ultra-low latency less than one frame. This dual-channel encoder is housed in a half-width rack enclosure with front-to-back air flow, and is ideal for high-density, compact installation in a centralized equipment location.

Easy to Configure, Simple to Manage

OmniStream AV over IP systems are remarkably easy to set up and manage – whether for a meeting room, retail establishment, auditorium, divisible room, or an entire university campus. Velocity™ Device Manager features automatic network device discovery, plus an intuitive web-based GUI that lets you configure virtual routing for AV, control, and data over the network – just as easily as you would with conventional AV matrix switching. Velocity Device Manager also streamlines and simplifies management of OmniStream systems through continuous system monitoring, notifications and alerts, event logging, multi-device configuration and backup, automated firmware updates, remote device control, and more.

Networked AV Redundancy

The OMNI-112 can provide networked AV system redundancy in conjunction with two OMNI-121 AV decoders. It can deliver two simultaneous encoded streams from an HDMI source, with the two channels connected into primary and redundant networks.

Product Compatibility

The OMNI-112 is compatible with the OMNI-121 decoder, as well as the OMNI-521 decoder.

Designed for Pro AV Integration

The OMNI-112 includes several features for optimizing integration and enhancing professional AV presentations. EDID and HDCP management features ensure reliable, consistent system operation and compatibility with source devices. EDID management includes the option to assign an EDID captured from a display at an OmniStream AV decoder. Aspect ratio controls are available to specify the presentation viewing format as desired by the end user. Additionally, OmniStream offers the option to overlay a logo image (PNG with transparent background) onto an AV presentation for corporate or institutional branding. A full-screen image can also be displayed, as a backup in an event of an interruption in an AV stream, or to display information between presentations.

OmniStream delivers fast switching between 4K/60 video streams from OmniStream encoders. Encoded video streams can be previewed in a Velocity™ touch panel GUI, or through the web GUI for an OmniStream decoder.

Ethernet Link Testing

OmniStream AV over IP systems feature Ethernet link testing, a convenient feature for integrators and technicians to test integrity of the network infrastructure. Testing is initiated from the encoder web GUI, and performed between an encoder and decoders joined to it in a multicast group. Test results can be monitored from the encoder and decoder web GUI, avoiding the need to visually check for an image at each display location.

Bug Fixes

Encoder

  • For HDCP sources that are only capable of HDCP 1.4, the encoder HDCP mode must be forced to HDCP 1.4.
  • Setting AppleTV to “Best Available” audio results in no audio detected during movies.
  • Slate insertion doesn’t work on the encoder.
  • While HDR does pass correctly, the encoder’s HDR indicator doesn’t show HDR for some sources, such as Xbox One S/X, PS4 Pro, and DirecTV C61K-700.
  • To prevent VQ issues, Kaleidescape Strato should be set to “Use External Scaler” mode and set to 1080p. This prevents menus from rendering in UHD.
  • HBR audio formats (Dolby® Atmos®, Dolby TrueHD, DTS®:X, DTS-MA) were temporarily removed from encoder EDIDs
  • DirecTV STBs loses 720p as an option, forcing the use of 1080i for non-UHD channels.
  • 1080i VQ needs improvement.
  • Video generator on encoder doesn’t work.
  • IR pass-through does not function.
  • WebGUI window for alarm descriptions is sometimes too small, resulting in truncated alarm messages.
  • VESA resolutions should not be available for R-Type.
  • Pro only: When both sessions are mapped to the same interface, audio from session 2 is corrupted.

Decoder

  • If dual sources are connected, one is UHDp60, and only one PoE is connected, the second input should not work and an alarm should be raised stating that dual PoE is needed.
  • Output drops when decoder is configured for ultra-low latency mode and UHD output.
  • HBR audio formats (Dolby Atmos, Dolby TrueHD, DTS:X, and DTS-MA) aren’t supported on the decoder.
  • Pro only: Pausing audio on PC sources sometimes triggers audio redundancy switching.
  • Infrequent drops with some 720p inputs.
  • Partial fix: Video wall size is limited to 5×5 within the web GUI. Larger wall sizes can be created over Telnet/API or using the Velocity Video Wall configurator.
  • Pro only: Polarity of analog input is wrong.
  • Enabling logo on the decoder with a UHDp60 source causes the output to blink and the unit becomes inaccessible.
  • Compressed audio from Kaleidescape Strato is unstable. The issue is not seen with PCM audio from the Strato.
  • Automatic bit depth reduction based on the sink’s EDID is done without any indication to the user.
  • Decoder audio downmix is missing “auto” mode which should function based on the EDID of the connected device.
  • Unit requires one extra reboot after an upgrade to get the decoder audio downmixing to work properly.
  • R-Type only: IR should only be allowed on serial port 2, but is also allowed on serial port 1.
