Video Reference
The flexible reference system in the switcher allows you to use an Interlaced video format as the reference to operate the switcher in a video format of the same frequency. Choosing a progressive video format as a reference limits you to operating the switcher only in that same video format and frequency. For example, if you have a 1080i 59.94Hz input reference you can operate the switcher in 720p 59.94Hz, but not 1080i 50Hz. However, if you have a 720p 59.94Hz input reference, you can only operate the switcher in 720p 59.94Hz.

- Network Connections
  Setting up network connections to the switcher, as well as network storage and file transfers.
- System Access
  Enable or disable system access and control methods such as RossTalk and FTP.

  - Supported Reference Formats
    The switcher supports a number of reference modes for both internal and external reference signals. References to 1080p 59.94Hz (A) and 1080p 50Hz (A) refer to 1080p Level A only.
  - Switcher Modes
    Set the video format the switcher is operating in as well as the resources and options that are available.
    - To Set the Switcher Mode
      Set the type of video formats that you want the switcher to operate in. This also selects the features and resources that are available on your switcher.

  - Switching Field (HD Only)
    The switching field is the field in an interlaced video format that the switcher uses to transition from one video source to another. An interlaced video format is made up of two fields, field 1 (odd lines) and field 2 (even lines).
- Video Inputs
  External video sources come into the switcher through the input HD-BNCs and internal sources are generated internally. 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
  The frame has a number of output HD-BNCs that can have any video source in the switcher, including Media-Store channels, aux bus, and clean feed assigned to them.
- 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.
- Splicers
  Splicers allow you to use DVEs to position up to four sources (2×2) on a single output. This can be used to position and stitch together the canvas outputs (MiniME™/Tiles) for the downstream LED processors.
- Frame Sync and Format Conversion
  The frame synchronizer / format converter (FSFC) and input i-to-p converters that 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. Output format converters are only available on outputs 5-14.
- 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.
- Input Media-Stores
  Video inputs must be configured as a Media-Store for that Media-Store channel to be available as a source.
- System Real-Time Clock/Date
  The switcher uses an internal clock to generate the time for the clock overlay for the MultiViewer.
- 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 crosspoint, and on the output from the switcher. Correction applied to the input video is then available to all MEs. Output based correction is only available on output BNCs 5 to 14.
- 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.
- 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.
- 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.

Switcher Mode Resources

When the switcher is operating in a UHDTV1 video format, the number of available resources is reduced to provide the additional processing power required for UHDTV1 production. The following table provides a quick overview of how the resources are re-allocated.

Note: Values represent maximum resources with all options installed.

Table 1. Switcher Mode Restrictions
	Mosaic HD	Mosaic UHD
MiniME™ Engines	10	6
Keyers per MiniME™	4	4
2D DVE Channels Switcher Wide	18	8
I/O MultiViewer (Max)²	2	1
Input FSFCs (Max)²	24	7
Output FCs (Max)²	10	4
Frame Delay (Max Frames)	13	7
Proc Amp/Color Correctors (Max)²	34	7
Media-Store Channels (Video³)	24	7⁴
SDI Video Inputs	24	18
SDI Video Outputs	14⁶	12⁶

Notes:

¹ Each Canvas consumes MiniME™ engines to generate the output. The number of Canvas outputs that are available depends on the number of MiniME™ engines that are available.

² Software options are required to be installed to activate the maximum number of resources.

³ When a media item with an alpha is loaded into a channel, the alpha is loaded into the next channel. A media item with alpha uses 2 channels.

⁴ An FSFC must be assign to an input so that it can then be configured as a Media-Store.

⁶ Not all outputs are configurable.
