Transferring Playback Queues Between Devices

Abstract

In some implementations, a computing device can transfer a playback queue between the computing device and a playback device. For example, the computing device can detect when the computing device is within a threshold distance of a playback device. The computing device can establish a connection to the playback device and receive state information describing the media playback state of the playback device. The computing device can determine the media playback state of the computing device. The computing device can present graphical user interfaces for initiating a transfer of a playback queue between the computing device and the playback device based on the playback state of the devices. The computing device can initiate a transfer of the playback queue in response to user input to one of the graphical user interfaces or automatically based on the context of the computing device.

 stopping, by the computing device, playback of a currently playing media item;   recording, by the computing device, a time offset in the currently playing media item where playback is stopped; and   storing, by the computing device, the time offset in corresponding media item data in the playback queue.   
     
     
         8 . A non-transitory computer readable medium including one or more sequences of instructions that, when executed by one or more processors, cause the processors to perform operations comprising:
 determining, by a computing device, that the computing device is within a threshold distance of a playback device;   determining, by the computing device, that the playback device is not authorized to playback media items of a playback queue, the playback queue comprising identification of a plurality of media items for playback and media item data for each respective media item of the plurality of media items;   requesting, by the computing device, a delegate token from a media server to allow the playback device to playback media items of the playback queue;   receiving, by the computing device, the delegate token from the media server; and   transferring, by the computing device, the delegate token and playback of the playback queue to a media application on the playback device.   
     
     
         9 . The non-transitory computer readable medium of  claim 8 , wherein the operations further comprise:
 receiving, by the computing device, a broadcast signal from the playback device, the broadcast signal comprising a device identifier of the playback device,   wherein playback of the playback queue is automatically transferred to the media application on the playback device in further response to recognizing the device identifier of the playback device.   
     
     
         10 . The non-transitory computer readable medium of  claim 8 , wherein the delegate token allows the playback device to access the media items of the playback queue through a media service account corresponding to the computing device.
