5.7 UMD Sources

UMD sources[^umd] are used to display tally indicator frames around camera images in the workspace. These frames illuminate when a signal is present and active on the associated UMD source — for example, when a broadcast director selects a particular camera for the live feed.

[^umd]: Under Monitor Display (UMD) is an indication device used for visually labeling cameras or monitors, and also the name of a control protocol operating over UDP. The protocol supports four indicator states: off, red, yellow, and green.

For tally indication to work, at least one of the following control signal input configurations must be in place:

  • A network source that provides a control signal via the TSL UMD protocol (version 3.1 or higher).
  • A GPI interface board from Stream Labs (USBIO-4/4, 16/8, or 24/4) installed on the node to receive the control signals.

To start working with UMD sources, navigate to the Configuration screen and select UMD sources in the Monitoring objects & virtual services section. The UMD source management screen will open (Figure 169).

UMD Source Management Screen

The screen consists of two panels:

UMD Sources panel — a list of all configured UMD sources. The table includes the following columns:

  • Name — the name of the source, defined by the user.
  • Type — the source type: TSL or GPI.
  • Is disabled — a flag that disables the source. Enable this checkbox if the source should be created in a disabled state.

Configuration panel — lists the monitoring objects (services) that are associated with the selected UMD source and will receive tally indication from it.

Adding a UMD Source

To define a new UMD source, click the New source button. The source creation window will open (Figure 170).

Figure 170. Window for adding a new UMD source Figure 170. Window for adding a new UMD source

Enter the following parameters for the new source:

  • Name — a user-defined name for the source.
  • Source type — select TSL or GPI.
  • IP address — the IP address of the TSL UMD source. Applicable to TSL sources only. Must be a multicast address. Make sure the multicast group is reachable from the nodes where the monitored objects reside (see Figure 171).
  • Port — the port of the TSL UMD source. Applicable to TSL sources only.
  • Device — the GPI board that will serve as the source. Applicable to GPI sources only. Select from the list of boards installed on the node.

Assigning Monitoring Objects to a UMD Source

For each UMD source, you need to specify which monitoring objects will be indicated with tally frames. Any number of objects can be assigned. To do this:

  1. Select the UMD source from the list. The Configuration panel will show any objects already assigned.
  2. Click the New service button. The service addition window will open (Figure 172).

Figure 172. Window for adding a new UMD service Figure 172. Window for adding a new UMD service

  1. For the new service, specify the following parameters:
    • Monitoring object — the monitoring object for which tally indication should be created.
    • Screen ID, Display ID, UMD number — TSL protocol parameters that identify the monitoring object on the UMD device. Obtain these values from the specialist responsible for configuring the TSL UMD source.
    • IP interface — the IP interface of the node where the monitoring object is located (shown with a black circle in Figure 171). This interface must have access to the multicast group specified in the UMD source configuration.

Once UMD sources are configured and monitoring objects are assigned, you can add Tally indicator widgets to workspaces and mosaic cells.
