Abstract: Mobile devices that perform synchronization operations are configured to reduce the amount of data that must be synced to perform a media content sync operation over a wireless connection. The sync operation is implemented as a two-phase arrangement, synchronizing first in a metadata sync operation and then in a media content sync operation. The source device transmits to the destination device a last known version number of the music database that was synced to the destination device and a current version number of the media database at the source device. In response to a failure of the network connection before completion of the metadata sync operation, upon establishment of a second network connection between the source device and destination device, the metadata sync is completed only for any version numbers that indicate a version subsequent to the last version number that was synchronized over the first network connection.

Abstract: A user listening to a content item on a preceding device and wishes to continue with the listening experience on a subsequent device initiates a continuity request from the subsequent device to the preceding device. The preceding device responds to the received continuity request by determining a multiverse identification that is contained in the continuity request, such that the multiverse identification uniquely identifies the content item that is currently playing on the preceding device over all known playback devices with which it has communicated. The subsequent device determines if the content item exists in a local database of the subsequent device and, if it exists, the subsequent device plays the content item from the local database of the subsequent device, and otherwise obtains the content item.

Abstract translation: 执行同步操作的移动设备被配置为减少必须同步的数据量以通过无线连接执行媒体内容同步操作。 同步操作被实现为两相布置，首先在元数据同步操作中，然后在媒体内容同步操作中同步。 源设备向目的地设备发送同步到目的地设备的音乐数据库的最后已知版本号以及源设备处的媒体数据库的当前版本号。 响应于完成元数据同步操作之前网络连接的故障，在源设备和目的地设备之间建立第二网络连接时，元数据同步仅针对指示最后一个版本之后的版本的任何版本号完成 通过第一个网络连接同步的版本号。
