Challenge

Schools, colleges, and universities have vast amounts of information to communicate to students, even outside the classroom. This includes class schedules, campus events, safety procedures, menus, weather, emergency announcements, and more. Visitors can also benefit from school promotional videos, campus maps, and special event information. Video walls are a great way to provide this information in a centralized, visually stimulating manner.

Solution

Atlona OmniStream™ is a flexible, scalable, and cost-effective AV over IP distribution platform that is ideal for video wall deployments. Omnistream networked AV encoders handle encoding of HDMI sources such as computers, set-top boxes, and media players onto a Gigabit Ethernet infrastructure. These sources can represent a wide array of content for display on the video wall including campus promotional videos, social media feeds, news, weather, sports, performances, event schedules, cafeteria menus, and more. Omnistream networked AV decoders handle decoding AV content for each of the displays in the video wall. Atlona’s Velocity™ System provides easy to use system control and flexible routing of content to the displays.

Challenge

There is a quickly emerging necessity in educational institutions for instruction to be provided to students off-campus and at home. The desire is to replicate the in-person teaching experience as much as possible. The challenge is even more acute if the instructor needs to work from home.

A key for any system solution would be to capture the instructor next to the screen, as in a normal class session. The system also should be adaptable to a range of functional requirements.

Solution

Atlona offers the OME-MS42-KIT and HDVS-CAM camera. This combination provides essential AV and USB device interfacing for the camera, a display, and the instructor’s laptop running Zoom or other video conferencing platform, plus USB extension to place the camera sufficiently away from the instructor.

If acquired for the instructor’s home, the system can later be installed permanently in a classroom with a document camera, audio system, and a PC or appliance for lecture capture.

Application Design

High-Impact AV over IP Video Wall

Three AT-OMNI-112 dual-channel networked AV encoders handle encoding of six HDMI sources at resolutions up to 4K/UHD HDR onto a Gigabit Ethernet infrastructure. Sources are a mix of computers, set-top boxes, and media players allowing a wide array of content to be available for display on the video wall.

Nine AT-OMNI-121 single-channel networked AV decoders handle decoding of network streams and image processing, as well as provide AV content up to 4K/UHD HDR and control signals to their assigned displays in the 3×3 video wall.

The Atlona Velocity VTP-800 touch panel and VGW-HW-3 hardware gateway act as the control system for the video wall. A single button on the panel starts the system by turning on all the displays, as well as initiating the default preset for source routing and video wall layout. Users can customize the layout of the video wall by selecting another preset on the touch panel or using drag-and-drop mode where any source can be dropped on any individual or combination of displays in the wall.
