Live Text

A Live Text state consists of an image overlaid with various text fields and/or media. You can layer both static text and updatable RSS and MRSS content on top of images and customize the position/size of items in relation to the background. You can even use Live Text to overlay content on top of a video in another zone.

To add a Live Text state to your presentation, drag the Live Text icon from the Other tab to the playlist area and set the following parameters:

• State name: Enter a unique name for the Live Text state.

• Set as initial state: Check this box to make the Live Text state your Home Screen.

• Background Image: Click Browse to locate and select a background image for your Live Text.

• Update Live Text Data: Click this button to have all Live Text Data fields display their current value.

Changing the Size/Positioning of a Live Text Item

Click the  Add Item button to add a new text/media item to the Live Text canvas. You can then edit the size and positioning of the item:

• Size: Adjust the size of a text field or item.

  • W: The width of the text field or item

  • H: The height of the text field or item

• Position: Adjust the position of a text field or item.

  • X: The position of the text field or item on a horizontal axis

  • Y: The position of the text field or item on a vertical axis.

Open

• Offset next: Check this box to set an initial position for new items in relation to the most recently created item. Input the offset distance for the next text item in the X and Y fields.

Selecting the Item Type

Use the Type dropdown menu to select the source of the content in the selected item:

• Fixed Text: Displays simple, static text. A text field will appear below Text Type, where you can type your customized text. As you type, you can view the text in the preview image.

• System Variable: Displays the device serial number, firmware version, script version, or other System Variable value. Use the dropdown list to determine which value you would like to display.

• Live Text Data: Displays content from a Data Feed in the text field. The displayed Data Feed item will remain fixed and will not cycle through feed items like an RSS ticker (use the RSS Feed type for this functionality). However, you can still update the text in real time by modifying the feed on the server and changing the description associated with the item title or index.

  • Add Data Feed: Click this button to add a Data Feed to your presentation. You can use any feed type (RSS, Live Data Feed, MRSS, Dynamic Playlist) as Live Text Data, but you must specify the Data feed content usage as Text when adding the Data Feed.

  • Item title: Specify the feed item to display using the Title/Name of the item.

  • Item index: Specify the feed item to display using the index number of the item.

Use the dropdown list to pair the Media Counter field with a file in the presentation. To use this feature, Media Counters must first be enabled: Navigate to File > Presentation Properties > Variables and check the box labeled Automatically create media counter variables.

• User Variable: Displays the current value of a User Variable. Use the dropdown list to specify a User Variable for the text field. To use this feature, you must first create a User Variable.

  • Display Media RSS description: Check this box to display the description of the MRSS item.

  • Display Media RSS media: Check this box to display the media item associated with the MRSS item.

  • Custom fields: If your MRSS feed contains custom text fields, this section will allow you to show or hide the custom fields as required.

• Image : Select this option to display an image over the background image. Select Browse to locate an image file to use in this item.

Customizing the Text Parameters

Click the Set Text Parameters button to customize the parameters for a selected field. 

• Alignment: Use the dropdown list to set whether the text is left aligned, right aligned, or centered.

• Foreground text color: Click Choose to select a color for the text.

• Background text color: Check this box to include a background color for text fields. Click Choose and set a default color for the backgrounds.

• Transparency: Drag the bar to set the transparency for the background text color. 

• Font:

  • Select Browse to locate and select a font for the text. You can use any TrueType or OpenType font. When selecting a font file, you cannot browse to the font files in the Windows fonts folder. You will need to copy the font file to your Desktop or another location and then select it using the Browse button in BrightAuthor.

  • Select Reset to System Font to reset the font to the default.

  • Select Automatic to fit the text to the height of the text field, or select Fixed point size to enter a value for the font size (1 - 500).  

Note that the default parameters of a text item will differ depending on how it is created:

• The first text item will use the default text parameters set in the Edit Preferences window ( Edit > Preferences > Live Text ).

• If you create a text item while another text item is selected, the new text item will inherit the parameters of the selected text item.

• If you create a text item without another text item selected, the new text item will inherit the parameters of the last created text item.

Layering Items

Use the Layer buttons to determine the layering of your Live Text elements. The background image is always displayed behind all elements.

Live Text with Video 

You can use a Live Text state to layer text and images over video. To do so, you must add the Live Text state to a Video or Images or Images zone, and place it on top of a Video Only zone. To help you position text over the video, we recommend using a screenshot from the video you want to use. Complete the following steps:

1. Under Layout, click Add Zone.

   1. Click Add Zone to add a Video Only zone.

   2. Click Add Zone again to add an Images or Video or Images zone.

   3. Set the Graphics plane z position of the Images zone to Front.

   4. Resize the Images zone so that it completely covers the Video Only zone.

2. Click the Playlist tab and select your Video Only zone.

   1. Drag the desired video file from the Media Library to the playlist area.

   2. Make the zone Interactive.

3. Use the dropdown list to select the Images zone.

   1. Make the zone Interactive.

   2. Drag the Live Text icon from the Other tab to the playlist area.

4. Click the Live Text icon to open the Add Live Text window.

   1. Click Browse beside Background Image.

   2. Locate and select the screenshot image file taken from the video file used in the Video Only zone.

5. Click Add Text Item.

   1. Adjust the Size and Position of your text field by clicking and dragging over the preview image or inputting exact numbers in the corresponding fields.

   2. Select your Text Type and input the desired text.

   3. Click Set Text Parameters and edit text parameters as desired.

   4. Click OK when finished.

6. Repeat step 5 for each text field you wish to add.

7. When all text fields are in place, click Clear next to Background Image.

8. Click OK.

Clearing the Background Image removes the image from the zone. The text fields will appear directly over the video. By temporarily including a Background Image taken from the video, you can better position the text fields in relation to the video playing behind the Images zone.

Sending UDP messages

You can use any application capable of sending UDP messages to display your UDP messages on screen. This example uses Hercules to send UDP messages to the networked player(s) playing the above presentation.

1. Open Hercules and go to the UDP tab.

2. Under Module IP, enter the player IP address and port 5000 (the default UDP sender and receiver port).

3. Under the server settings make sure to deselect Server echo, Redirect to TCP Server, and Redirect to TCP client.

4. Under Send, enter “cell1:new message” and click Send to display “new message” on the player. The string consists of "User Variable:the message".

5. You can also use one UDP string to update multiple Live Text items at the same time. To do so, you need to separate each message with a “!!”. For example, you can enter “cell1:my message!!cell2:my other message!!cell3:yet another message” and click Send.
