General

This part of the Programming page allows users to manage the available input resources. Sources are created and defined from the available Inputs that were defined on the System Configuration page.

About Sources and Inputs

Source are defined from input signals. Multiple sources can be defined from the same input. After a source is defined, then several attributes can be modified. These attributes are: color adjustments, crop, sharpness and mask. By default, a source is automatically created for each Input. Up to 256 sources can be created form the same input. As with inputs, sources can be defined from multiple connectors, ex: 4K or DL DVI and as a single link or dual link.

Note: The multiviewer displays input signals not sources.

Few words about Inputs, Sources and Layers

Input

• Definition: Any video signal connected to the Event Master series processor.

• Features:

  • An input signal can be 2K (Single Link), Dual-Link or 4K (Ultra-HD) format.

  • Depending on the resolution and type of the input signal, multiple connectors may be required to connect an input signal to the Event Master series processor. The number of connectors required is listed in the table below.

    	2K Resolutions up to 2048x1200@60	Dual Link Resolutions up to 3840x1200@60	4K (Ultra HD) Resolutions up to 4096x2160@60
    SDI	1	2	4
    DVI	1	1	2
    HDMI 1.4a	1	1	2
    DisplayPort 1.1a	1	1	2

• Adjustments:

  • Name, Colorspace, Connector capacity, Auto Acquire, EDID, Contrast, Brightness, Gamma.
  • Adjustments to an input signal have an effect on all sources that are derived from the input signal

Source

• Definition: A video signal created when an input is manipulated to create a desired look.

• Features:

  • When an input is created, a source is automatically created with the same attributes as the input.
  • Multiple sources can be generated from the same input signal.
  • Any source can be dropped into any layer and any destination.
  • The same source can be used in multiple layers and multiple destinations.
  • It should be noted that if a source is used in multiple layers and a source is modified in one of the layers, it will not be automatically updated in the other layers. To update the source in the other layers, it needs to be deleted from these layers and re-inserted from the sources list.

• Adjustments:

  • Name, Bind to User Key, Layer Aspect Ratio, Size, Position, Contrast, Brightness and Hue.

Layer

• Definition: A layer is one image stacked on top of another or a background.

• Features:

  • Each mixer layer has two layers, Preview and Program. For complete flexibility, each layer can be assigned to either PIP or Key functionality.

    

  • The mixing Background layer (BG) has the lowest priority.
  • On any mixing layer, a PIP layer appears over backgrounds and under other layers of higher priority.
  • PIP effects include mixes, resizing, and adjustable aspect ratio..
  • A Key layer also appears over backgrounds and under other layers of higher priority. Key effects include luminance keys and chroma keys.

• Adjustments:

  • Layer Size & Position, Source Size & Position and Mask.

• Layer Effects

  • Strobe, Flip, and Freeze.

Input, Sources and layer example

Source Area description

In this menu, Sources defined in the Configuration menu are assigned to destinations via drag and drop procedure. Each input has minimum one Source file, several can be created via copy original (Plus Icon) or copy file (Double Page Icon).

There are 2 tabs in this section:

• Source: Lists Inputs and Sources available in the system. Sources are listed after the input and can be view by clicking on the arrow next to the Input name. Stills and Destinations can also be used as sources.
• Background: Lists backgrounds and background still stores available for destinations.

For each of these lists two display modes are available. Toggle the view by clicking on appropriate icon:

	List View
	Thumbnail View

Inputs (List view)

Inputs (List view)

Resolution: This is the resolution of the Input signal. The LED color indicates the status of the input: Red: Sync is missing or invalid format. Green: Sync is valid. Refreshes the Input thumbnail (in Thumbnail View) from the Input source. Freezes the Input. Allows a snapshot to be taken and stored as a Still. Adds Sources based on the inputs. A total of 256 are allowed per input. Copies the Source into a new Source and adds it in the list.

Inputs (Thumbnail view)

Thumbnails are added manually and in the future added from the Event Master series processor to the GUI. From Release 1.5 this works for Stillstores.

Inputs (Thumbnail view)
	Behavior is similar to the List View mode (see above).

By clicking in thumbnail area images can be imported using the file picker menu. The picker can select pictures with the BMP, JPG or PNG format.

Stills (List view)

Stills (List view)

Stills can be added from external source of the GUI computer in the PNG format. A PNG with a transparency is marked in the Stills list with a (T). Name that can be changed by double click action and then the resolution of the Stillstore. [Disk Icon] indicate the memory required for the Stillstore. A total of 100 HD Stillstores are possible. Higher resolution images use more memory per image, resulting in fewer still images being available on the system.

Stills (Thumbnail view)

The system automatically adds thumbnails once the live capture or file import has been processed.

Stills (Thumbnail view)
	Behavior is similar to the List View mode (see above).

By clicking in thumbnail area images can be imported using the file picker menu. The picker can select pictures with the BMP, JPG or PNG format.

Destination

Destination (List view)
Destination (Thumbnail view)

The Destinations can be used as a source in Layers provided they have the capacity to fit. Up to 2K resolutions on SL, up to 4096 x 1200 / 2560 x 1600 for DL and 4K / 8192 x 1200 for 4K Scaler Mode.

How to delete sources

The delete process is similar for all lists with more than one entry. To delete Sources the user need:

1. Click on the Delete Source(s) button.

   The Delete Source(s) button turns in red and the delete icon (“x”) appears next to the copy icon on each element of the source list.

   

2. Select the sources that you desire to delete and click the Delete Source(s) button.

   The selected sources are removed.

How to hide Inputs

As the inputs are usually named after its physical names while the sources are named after the Show Usage we allow to hide the inputs from the list:

1. Check the Hide Inputs box.

   Sources are displayed without their associated Inputs.

   

Background Stills

In this menu, Background Stills captured in the Background Source menu are assigned to destinations via drag and drop procedure.

Background Stills and Destinations need to have the same resolution including the Destinations eventual blend overlap. For example, if a background Stillstore is captured as 3500 x 1080, then the destination must also have the blend resolution of 3500 x 1080.

Background Stills (List view)
	Name: This is the Name of the Stillstore as created in Background menu. Name can be changed by double click action. Resolution: This is the resolution of the Stillstore. [Disk Icon] Indicates the memory required for the Stillstore. A total of 100 HD Stillstores are possible. For higher resolutions the corresponding increase of memory is used.

Thumbnails are added manually and in the future added from the Event Master series processor to the GUI. From Release 1.5 this works for Stillstores.

Background Stills (Thumbnail view)
	Behavior is similar to the List View mode (see above).

By clicking in thumbnail area images can be imported using the file picker menu. The picker can select pictures with the BMP, JPG or PNG format.
