Webapps & Overlays

There's two ways you can make use of the TelemetryTV Javascript SDK:

Type	Use Within
HTML App	Add an App to a Playlist Zone that is of the type HTML
HTML Overlay	Enable the HTML Overlay within the Overlay section of the Playlist properties.

The HTML App is like other TelemetryTV Apps in that it exists within a Playlist Page on a Zone. It is automatically created when the page is displayed and disposed of when the page is removed.

In contrast the HTML Overlay persists through-out the playback of the Playlist. It is only created when the Device starts to display the Playlist and then it is disposed when the Device restarts.
