MultiScreen works by breaking your display into individual panels. Each panel is represented by a tile in MultiScreen and the entire display is represented by the canvas.

Setup
Reference and video I/O setup, canvas layouts, and signalling setup.
- Network Connections
  The switcher requires a network connection for the DashBoard interface as well as any control panel you want to use.
- System Access
  Enable or disable system access and control methods such as RossTalk and FTP.
- Video Reference
  The switcher uses the REF A or B input reference signal on the router directly as a reference clock. The switcher does not rely on the reference settings in Ultrix™ for a reference signal.
- Video Inputs
  Video sources come into the switcher either from the router matrix, or through the HD-BNCs on the SDPE blade. Depending on how you want to use these video sources, or where they come from, you may want the switcher to pair them together, or associate an external device with them. Pairing two video sources together is usually used for an auto select key where an external device, such as a character generator, outputs both a key video and key alpha. Associating a video source with an external device allows special control over that device to become active when you select the source on a bus.
- Video Outputs
  Switcher outputs are routed to destinations in the router matrix or to the HD-BNC on the SDPE blade directly.
- MultiViewer
  The MultiViewer allows you to view multiple video sources from a single output BNC. Video inputs or outputs on the switcher, including Program, Preview, and Media-Store channels, can be assigned to any box on the MultiViewer.
- MultiScreen
  MultiScreen works by breaking your display into individual panels. Each panel is represented by a tile in MultiScreen and the entire display is represented by the canvas.
  - MultiScreen Video Processor Setup
    The MultiScreen compositing engine allows you to map switcher outputs (Tile/MiniME™) to regions on your LED display (Canvas). With the tiles laid out on the canvas, background images can be stretched (Background DVE) or tiled (Pre-Tiled Source) across the entire canvas.
  - To Set Up MultiScreen
    Create your canvas and then overlay tiles to cover the canvas area with video.
  - To Set Up a Pre-Tiled Source
    The substitution table is a single table that allows you to specify a different source that should be taken when a specific source is selected on a bus. The substitution table requires either a Canvas or ME follow to be set up between the buses to trigger the substitution.
- Frame Sync and Format Conversion
  The frame synchronizer / format converter (FSFC) and input i-to-p converters can be used to convert video signals as well as correct mistimed, or drifting, video input signal. The frame synchronizers cannot completely correct badly formatted video, mistimed switches, signal drops, or similar issues.
- Frame Delays
  A delay of up to 13 frames in HD, or 7 frames in UHDTV1, can be added to any input that an FSFC is assigned to. This allows you to delay the timing of an input to compensate for the delay in another source. For example, in a virtual set environment it may take a few frames for the system to track the position of the camera and render the background. In this case you want to delay the foreground cameras to compensate for this delay.
- System Real-Time Clock/Date
  The switcher uses an internal clock to generate the time for the clock overlay for the MultiViewer.
- Audio Output
  Audio sources from the audio mixer, clip player, and Media-Store can be sent out the AES outputs of the frame.
- Color Correction
  The color correctors can operate as Processing Amplifiers (Proc Amps) in the HSL (Y-Cr-Cb) color space or as RGB Color Correctors in the RGB color space. Proc Amps and RGB Color Correctors apply color correction to video on input to the switcher, before the switcher crosspoint.
- Personality
  Personality settings allow you to configure how you interact with the control panel and switcher, as well as how the buttons on the control panel appear. All of these settings are stored in the Personality register.
- Licenses
  Software options allows you to expand the functionality or resources available to the switcher as well as operate in UHDTV1. These options can either be licensed at the time you purchase your switcher, purchased and installed later on, or temporarily licensed through the Ross Platform Manager (RPM).
- GPI Control
  General Purpose Interface (GPI) is a high/low voltage signalling protocol that allows the switcher to send simple commands to an external device, or receive commands from a device. Each pin on the GPI is set as either high (+5 Volts), or low (0 Volts), and it is the switching between high and low that sends commands to the external device, or to the switcher.
- Live Edit Decision Lists (LiveEDL)
  Edit Decision Lists are files used by non-linear editing (NLE) suites to aid in post-production. Your switcher can capture EDL data in a file that you load into your NLE suite.
- ViewControl
  The ViewControl interface through DashBoard allows you to coordinate the control over the Carbonite switcher, XPression Live Graphics System, and a Tria Playout Server all through a touchscreen interface. Through ViewControl you can select sources, perform transitions, and run custom controls.
- MultiPanel
  Each frame supports up to 3 independent control connections (Main, Satellite 1, and Satellite 2) as well as Satellite 3/SoftPanel. Each connection, with the exception of SoftPanel, can be from a control panel, DashBoard, or a combination of the two. All devices on the same control connection mirror each other.

MultiScreen

MultiScreen works by breaking your display into individual panels. Each panel is represented by a tile in MultiScreen and the entire display is represented by the canvas.

To properly set up MultiScreen you must calculate the total number of pixels on your display (width and height). In the example shown below we are using a display that is 3840 pixels wide and 2160 pixels high. This information is entered as the canvas size.

Tip: MultiScreen uses a MiniME™ to create a tile. The two terms are used interchangeably in the menus.

Once the canvas has been set, you need to calculate how many tiles it will take to cover the canvas. The size of the tiles is determined by the video format the switcher is operating in. For example, if you are a 1080 format, each tile will be 1920 pixels wide by 1080 pixels high. MultiScreen can automatically position the tiles in an X by Y grid over the canvas.

Tip: If your canvas is larger or smaller than the grid of tiles, make sure to use enough tiles to cover the entire canvas.

Putting video onto the tiles can be done in a number of ways, depending on how the background graphic you want to use was created. In the case of a pre-tiled source, the background image has already been divided up into individual segments. A separate video source is fed into the switcher for each tile. In the example below, tile 1 is fed the video source on BNC 1 (Source 1), tile 2 is fed form BNC 2, and so on.

Tip: When dealing with pre-tiled sources, it is recommended that you set up a substitution table for all the sources you will use. This allows you to select a source on one MiniME™ and have the switcher automatically select the corresponding sources on the other MiniME™ buses.

Alternatively to the pre-tiles sources, MultiScreen can use DVE resources to stretch a single image over the entire background.
