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.
