    Abstract: 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.

    Abstract translation: 一种方法包括经由音频回放设备从主机数字媒体服务器的计算机接收第一多播传输(例如,SSDP(HTTP)/ Bonjour(DNS)存在通知)。 第一组播传输提供在网络(例如,LAN)上数字媒体服务器(例如,DLNA音乐服务器)的存在的指示。 单播连接的请求经由音频播放设备发送到数字媒体服务器,并且在没有响应于单播连接的请求的情况下,经由音频播放设备发送第二组播传输。 第二组播传输包括允许数字媒体服务器建立与音频播放设备的连接以便于传输针对内容的单播请求的信息。
