/* * Dash Media Player: External Interface Gateway * Copyright (c) 2008 TMT Digital LLC. * * Author: Travis Tidwell | http://www.travistidwell.com * * Dependencies: * jQuery Library * * This script is used as a connection interface gateway to control the player from an external source. * It is also used as a means for communication between multiple instances of the Dash Media Player * on the page. This allows you to separate the Playlist and the actual * player on the page, but yet have them behave as a single player. For more information on how you can * integrate this great feature on your website, visit http://www.tmtdigital.com/remoteplaylist * * License: GPL */ var dashReady = false; var dashObjects = new Object;
