Specifications include, but are not limited to: 3.1. Video Display Control System: The video display control system shall allow multiple authorized users to control and manage the display of video and computer-generated graphics on the display equipment connected to the system as well as provide selection and switching of multiple sources for display, including video streams available on the TERL Traffic Management Center (TMC) Ethernet network. The display control system shall also allow authorized users to control all displays from the same workstations used for existing TERL operations. The video display control system shall be able to simultaneously display up to a minimum of 48 video streams on various display layouts using existing TERL displays. The system shall allow display of multiple video windows containing streaming video from different sources using various common codecs (e.g., H.264, MPEG-2) at various resolutions and bitrates. Common resolution, frame rate, and bitrate for streaming sources includes 1920x1080, 30FPS, 3Mb/s video streams. The video display control system hardware shall be a specialized computing platform for video wall control and management that is designed to be rack mounted and secured in an EIA 19 -inch equipment rack and operated on an enterprise Ethernet network domain. Any Personal Computer (PC) hardware incorporated within the system shall use current microprocessor technology and commercial, off-the-shelf components, including RAM, hard disk drives, network interface cards, operating system, and applications. The video display control system shall be expandable and scalable to support any combination of inputs and outputs. The video display control system shall have a minimum configuration of 4 High-Definition Multimedia Interface (HDMI) inputs and 12 HDMI outputs. 3.2. Video Display Control Software: The display control software shall provide centralized system management functions and allow multiple authorized users to control all features and functions of the video display control system. These features and functions include, but are not limited to, creation of display layouts (i.e., customizable window arrangements that include multiple sources displayed at various sizes); selection of video sources for display, including switching layouts; adjusting the size, location, and layout of video and other graphic information the system displays; and system configuration and setup. The control software shall be able to operate display walls composed of multiple display components as though they are single, high-resolution displays. The system shall provide a user interface that allows users to create, edit, store, and recall content arrangement on multiple displays at the TERL (i.e., primary and secondary display walls as well as freestanding displays) and allow any display window to be sized from 1/32 of the total display area up to the total display area, and any size in between by dragging, dropping, moving, layering, and resizing content boundaries. The display control software shall include a documented Application Programming Interface (API) that describes interfaces and protocols which can be used to integrate system features and functions with third-party applications. The display control software shall accept external alarm triggers to automatically switch layouts. 3.3. Inputs and Outputs: The video display control system shall support and display a variety of video and data inputs simultaneously, including HDMI and network computer desktop graphics such as Video Graphics Array (VGA), Super Video Graphics Array (SVGA), and Super Extended Graphics Array (SXGA) computer graphics via remote desktop connections. All inputs and outputs shall allow authorized users to display any or all this information on any number of display devices within the system. All inputs, outputs, and display windows shall be able to be sized and resized with and without constrained proportions across multiple screens and moved at will around any display area and combination of displays. The video display control system shall be expandable and scalable to support additional inputs and outputs. The video display control system shall be provided with a minimum configuration of 4 HDMI inputs and 12 HDMI outputs. All HDMI interfaces must be HDMI 2.0 and capable of 4K resolution at 60 frames per second. The video display control system shall include all network connections, decoders, and associated hardware and software required to simultaneously display 48 video streams from different sources. The video display control system must be able to simultaneously display a single input source on multiple displays and multiple input sources on a single display. Switching between inputs or outputs shall not cause displayed images to unlock, roll, or otherwise exhibit visible distortion. 3.3.1. Network Connections: The video display control system shall use a single 10/100/1000 RJ45 Ethernet port for connection to the TERL network. If the video display control system requires multiple Ethernet ports to provide required functionality (e.g., additional ports for decoder card connections), the system must be supplied with a managed Ethernet switch that provides ports for additional connections. 3.3.2. Digital Video: The video display control system shall be able to accept digital video sources as well as manipulate and display these signals on any display attached to the system. All digital video inputs and outputs shall use HDMI connectors. All HDMI interfaces shall be HDMI 2.0 and capable of 4K resolution at 60 frames per second. 3.3.3. Streaming Media: The video display control system shall be able to display a minimum of 48 compressed video streams simultaneously. The video display control system shall display MPEG-2 and H.264 streams. Each video stream shall display within its own window and be freely movable and sizable up to or beyond its native resolution to conform to the wall display size. 3.3.4. Display Outputs: The video display control system must be able to process and manipulate various signal input types to be output and viewed on display walls and freestanding display monitors, such as multi-window layouts of streaming video feeds and desktop computer graphics (e.g., applications on network computers via remote desktop display windows). The output capacity shall have sufficient memory and processing speed to provide fast rendering of video and image displays simultaneously on a minimum of 12 HDMI displays. 3.4. Electrical Requirements: Provide equipment that operates on 120 VAC at a frequency of 60 Hz. Furnish a transformer or other necessary means of power conversion for any device that requires another voltage or frequency.
