UPnP AV Transport Service Using the Add-in System

Recently, variety specifications have been developed using universal plug and play technology. UPnP technologies allow home application controlling and sharing. People can now play or share media anytime they want and anywhere they are, if network-connected. In addition, digital living network alliance has developed this home networking theme. But many people feel inconvenienced with UPnP applications, such as UPnP control-point and UPnP Server. They are very complicated for users. If users try to play other devices(UPnP Server) files, it will take 5~6 steps of mandatory clicks or selections for them to do so. We focused on removing these inconveniences associated with UPnP applications user interfaces through developing a new concept. We simply called it add-in System. Our system provides UPnP A/V transport services through an embedded legacy media player such as, window media player, real-player. When users play media file in legacy media players, they can share media files through UPnP devices. Through our add-in system, users have no need to know about UPnP service scenarios or service steps. If users want to share media files, just one selection step is needed in our add-in system.
