A method includes receiving via an audio playback device a first multicast transmission (e.g., an SSDP(HTTP)/Bonjour(DNS) presence announcement) from a computer hosting a digital media server. The first multicast transmission provides an indication of the presence of the digital media server (e.g., DLNA music server) on a network (e.g., a LAN). A request for a unicast connection is transmitted via the audio playback device to the digital media server, and, in the absence of a response to the request for a unicast connection, a second multicast transmission is transmitted via the audio playback device. The second multicast transmission includes information that allows the digital media server to establish a connection with the audio playback device to facilitate transmission of a unicast request for content. |
