Abstract:
1. A method for sharing contents in an environment between devices using an Institute of Electrical and Electronics Engineers (IEEE) 1394 interface in a Digital Living Network Alliance (DLNA) system, the method comprising the steps of: transporting a SetAVTransportURI from a digital media player (DMP) to a digital media server (DMS); informing the DMS of a uniform resource identifier (URI) of a content to be transported; upon receipt of the SetAVTransportURI by the DMS initiating a connection between the DMP and the DMS using a predefined IEEE 1394 contents transfer protocol; upon completion of connection initiation, controlling a transport of a contents between the DMP and the DMS in accordance with the predefined IEEE 1394 contents transfer protocol; and upon completion of contents control and transport between the DMP and the DMS, terminating the contents transport in accordance with the predefined IEEE 1394 contents transfer protocol; wherein the DMP includes a digital media renderer (DMR) and a digital media controller (DMC), wherein the DMR has a UPnP device module and a HTTP client rendering a media, and the DMC enables a UPnP control point (CP) and has a media renderer CP module and a media server control point modules to control the DMS and DMR so that the DMS and the DMR of the DLNA system transport data according to each environment and control contents transport in the IEEE 1394 interface to provide a linkage therebetween.
