/* Real Player detection on a Web page.
* Version 1.0
* March 09, 2004
* Paul Davis <pdavis@real.com>, Real Networks Inc.
* This example illustrates how to detect an installed copy of Real Player to ensure proper playback of Real Media files embedded in a web page.
* If the user has IE5+, the code will attempt to instantiate the Real Player active X control and query it. If the user doesn't have IE5+, the code will 1st attempt to look for Real Player in the plug-ins array and then the mime-Type array.
* The code won't detect the presence Real Player if Netscape Browser 6+ is installed after installing Real Player. This is a known issue in Netscape browser.
* The code will return a "true" value if Real Player version G2 or above is installed, but it may not be able to detect the correct Real Player version number in all cases.
* The recommended next step, when the detection fails to find Real Player, is to redirect the user to a landing page, and allow the user to choose to either download Real Player or to play the embedded contents anyway. In the example, http://guide.real.com is used as the landing page.
* The URL to download the latest release of RealPlayer is http://www.real.com/player.
* Finally, the Real Player detection logic should be intended to enhance web user experience, and not to be used as a mean to restrict access to contents.
*/

/*
* The version variable will be set when we are able
* to detect the version. Note, we do not do comprehensive
* version detection, because of the time overhead in
* instantiating a plugin. This invloves creating an instance of
* the plugin (on non Windows IE5+ platforms), setting up a
* background thread to check when it is ready and querying
* the plugin for its version.
