Abstract:

When delivering multimedia content for the three major media players (Windows Media Player, Quicktime and RealMedia Player), the developer must choose whether to have the viewer access the content through a player embedded in a Web page or through a standalone player. Both methods have their advantages. Embedding the player in a Web page allows the user to access the content without another application opening. The standalone players usually have more control options.
