On Demand State

The On Demand state allows you to combine media files into a single state in the playlist area. You can then use the event that transitions to the On Demand state to conditionally determine which file in the playlist should be played.

When the On Demand state is double-clicked, the On Demand canvas will appear. The On Demand canvas gives you the option to add content from Assets to the On Demand state. To exit this canvas, click the Zone description located in the top left corner of the canvas. This will take you back to the Zone Content canvas. 

The On Demand state can only be transitioned to using input from BP900/BP200, UDP, Serial, Keyboard, or USB devices. The input data from the controller will determine which media item in the On Demand state will be played: For example, you can use a Keyboard Input event to playback “Video 1” if the “A” key is pressed, “Video 2” if the “B” key is pressed, "Video 3" if the "C" key is pressed, etc. Any type of event can transition out of a Play File state and into a new state.

For BP200/BP900 events, you must specify each Key using both the panel enumeration and button number: For example, if you have a single BP200/BP900 panel connected to the player and want button 3 to trigger an image, you would specify the Key as "0-3"; on the other hand, if you have a second BP200/BP900 panel connected to the player and want button 3 on the second panel to trigger the image, you would specify the Key as "1-3".

  • Populate From Feed: Populate the On Demand state using a feed.

    • URL: Specify the URL of an RSS feed (this feature does not support MRSS feeds). In the example below, <title> is the On Demand key value and <description> is the media download URL.Upon playing the presentation, the player will retrieve media from the download URLs specified in the <description> field of each item in the feed. The On Demand state will use the value in the <title> field as the key to determine which media item to play.

      <rss xmlns:media="http://search.yahoo.com/mrss/" version="2.0">
    <channel>
        <title>The Feed</title>
        <link>https://site.com/</link>

    • Dynamic Playlist: Populate the On Demand state using a Dynamic Playlist from your BSN Content Cloud library. The On Demand state will use the filename as the key to determine which media item to play.

    • Live Media Feed: Populate the On Demand state using a Live Media Feed from your BSN Content Cloud library. The On Demand state will use the Title of the feed item to determine which media item to play.

    • Update Interval: Specify how often the player should refresh the contents of the feed.

    • Parser Plugin: Select a feed parser to parse the feed data before it is passed to the On Demand state.

    • Optimize Feed Updates (use HEAD calls): Check this box to have the player make an HTTP HEAD request before retrieving the contents of a feed. See here for more details.

    • Automatically generate User Variables from Data Feed:  Use the feed to populate a set of User Variables for HTML pages. See here for more details.

  • Display default media if input does not match any keys: Check this box to display the specified media file when the input data does not match any existing keys in the On Demand state. If this box is not checked, and the input data does not match an existing key, the presentation will not transition to the On Demand state, remaining on its current state instead.

  • Use variable to specify key: Check this box to have a User Variable specify the media-file key. The input data from the controller will be ignored, though input of some kind must be received to trigger the interactive event. For example, if a Keyboard event is attached to the On Demand state and this option is enabled, any key press will initialize a transition to the Play File state; the value of the specified User Variable will then be checked against the keys in the On Demand state to determine which file, if any, should be played.

If you attach a command that modifies the User Variable value (e.g. Set Variable, Increment Variable) to an event that transitions to the On Demand state, the media-file keys will still be compared against the old variable value. However, if the Display default media option is enabled, the new User Variable value will be used instead.

Super State

If you create a large, complex interactive playlist, you will likely run into two problems: You’ll find yourself having to create a large number of redundant events, and it will become difficult to keep track of numerous branching states and conditions. Super States are implemented to alleviate these problems and make complex interactive presentations manageable.

When the Super State icon is double-clicked, the Super State canvas will appear. The Super State canvas gives you the option to add media states from Widgets to the Super State. To exit this canvas, click the Zone description located in the top left corner of the canvas. This will take you back to the Zone Content canvas. 

The primary mechanic of the Super State is that it functions as both a state and a self-contained interactive playlist. A Super State can be transitioned into and out of using any event, but double-clicking it will reveal a new interactive playlist canvas contained within the original. There are several behaviors that are unique to this state:

  • Each Super State contains a Home State: A transition to a Super State will point to the initial state within the Super State by default. However, you can point the transition to any other state within the Super State by opening the event and selecting the desired state from the Specify next state dropdown menu.

  • Super States can be nested inside other Super States: You can use the breadcrumb trail above the playlist area to keep track of where you are within the hierarchy of Super States.

  • Super States can have Entry and Exit Commands: Entry Commands are triggered when any state within the Super State is transitioned to. If a Super State is contained within one or more other Super States, a transition to or from that Super State will trigger Entry/Exit commands on all other Super States that will need to be moved through for the transition to reach its destination. Commands will be executed in sequential order, depending on whether the transition is ascending or descending through a hierarchy of Super States.

  • You can copy and paste, export Super States: All events, states, commands, and other Super States contained within the Super State will be copied over as well.

Video In State

The Video In state allows for live-video playback from another source via the HDMI® Input port on the XT1144, XT1143, and 4K1142 models.

Volume can only be changed using the Set Volume command when the presentation is interactive. Video states in a non-interactive state still utilize the Set Volume option in State Properties.

  • Overscan enabled: Check this box to display the video input beyond the edges of the zone. Use this option if the source video signal is using an overscan setting.

Live Feed State

The Live Feed state allows you to display media from an MRSS feed (or text from an RSS feed in Ticker zones). An MRSS feed can be hosted on a third-party server or your BSN Content Cloud network (using the Live Media feature). MRSS feeds can be used to play image, video, audio, and HTML content (different content types can be mixed into a single feed).

  • Source: Specify the feed source:

    • URL: Populate the Live Feed state from a remote URL.

    • Live Media Feed: Populate the Live Feed state using a Live Media Feed from your BSN Content Cloud library.

  • Content Usage: Modify other options associated with the feed:

    • Update Interval: Specify how often the player should refresh the contents of the feed.

    • Parser Plugin: Select a feed parser to parse the feed data before it is passed to the Live Feed state.

    • Optimize Feed Updates (use HEAD calls): Check this box to have the player make an HTTP HEAD request before retrieving the contents of a feed. See here for more details.

    • Automatically generate User Variables from Data Feed:  Use the feed to populate a set of User Variables for HTML pages. See here for more details.

Stream State

The Stream state allows you to play an IP stream from a local or remote source.

  • Audio: Play an audio stream.

  • Video: Play an audio/video stream.

  • MJPEG: Play an MJPEG stream.

  • Stream URL: Enter a valid URL for the stream. The URL can also include a number of optional parameters:

    • Specify a User Variable to replace all or part of the URL. To include the value of the variable in the URL, enter the variable name between two sets of dollar signs (e.g. "http://www.example.com/streams/{{my_URLvar}} ").

    • Append the "latency" and "jitter" parameters to modify the default latency (see this FAQ for more details).

    • Append the "buffersize", "vcdbsize", and "acdbsize" parameters to modify the default streaming buffer size (see this FAQ for more details).

    • Append the "lowlatency" parameter to reduce the default latency (see this FAQ for more details).

Dynamic Playlist State

The Dynamic Playlist state allows you to display media from a Dynamic Playlist on your BSN Content Cloud network. 

  • Source: Select a Dynamic Playlist to populate the state.

  • Content Usage: Modify other options associated with the Dynamic Playlist. 

    • Update Interval: Specify how often the player should refresh the contents of the Dynamic Playlist.

    • Optimize Feed Updates (use HEAD calls): Check this box to have the player make an HTTP HEAD request before retrieving the contents of the Dynamic Playlist. See this page for more details.

    • Automatically generate User Variables from Data Feed: Use the feed to populate a set of User Variables for HTML pages. See this page for more details.

Event Handler State

In some scenarios, you might want your presentation to sit at a blank screen. The Event Handler fills the role of an empty placeholder in your presentation. Here are a few cases where an Event Handler would be useful:

  • You want a blank screen for a Home Screen so no content will play until the presentation is activated.

  • You want to add a command that is performed before the first file in the presentation plays.

  • You want the presentation to sit at a blank screen when finished, instead of looping.

Although Event Handlers contain no content, you can add commands and interactive events into and out of them. For example, if you set an Event Handler state as the Home Screen and define a  BP900  event linked from the Event Handler state to the first presentation item, the display will sit at a blank screen until a user presses the BP900 button, and then the first item will begin playing. Alternatively, if you set an Event Handler as the Home Screen and add a  Synchronize  command to it, you can synchronize your presentations and/or displays before the first files begin playing.

User Variable State 

The User Variable state allows to display text from User Variables in a Ticker zone. Select a User Variable to display from the User Variables dropdown list.
