Abstract: In some implementations, a system can be configured to allow remote control devices to quietly obtain status information related to various audio/video playback devices. For example, a streaming device (e.g., a user device, phone, etc.) can establish a streaming connection to a playback device. The playback device can be configured to only accept a single streaming connection (i.e., master connection). A remote control device (e.g., a user device, phone, etc.) can quietly connect (i.e., control connection) to the playback device without interrupting the master connection to obtain status information related to the playback device and or the media being streamed to the playback device. The remote control device can provide commands through the control connection to adjust the playback of the streamed media at the playback device.

Abstract: In some implementations, a user device can predictively route media content to a remote playback device based on playback context information obtained by the user device. The playback context can include local playback context information related to the state and/or context of the user device. The playback context can include remote playback context information related to the state and/or context of available remote playback devices. Based on the playback context information obtained by the user device, the user device can generate a predictive score for each available playback device that indicates or predicts the likelihood that the user will want to send media content to the corresponding playback device. The user device can generate and present a graphical user interface that can identify the playback devices having predictive scores over a threshold score. In some instances, the user device can automatically route selected media content to a predicted playback device.

Abstract: Techniques are disclosed for developing spanning trees at devices that are interconnected in a rendering network. According to the techniques, a change in connectivity between two devices in the rendering network may be detected at a first one of the devices, information representing a cost of connectivity may be stored in a data record at the first device. A spanning tree may then be calculated from a candidate set of communication links that interconnect the devices of the rendering network according to cost information representing those communication links. A device may exchange information, such as information regarding the rendering network, to another device of the rendering network according to communication links identified for the spanning tree. The data record may be of a conflict-free replicated data type.

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.

Abstract: In some implementations, a computing system can be configured so that a first user device can delegate a first user's media account credentials to second user device corresponding to a second user. For example, a playback device may be configured with the second user's media account credentials for accessing media items through a network media service. A first user may wish to play media items associated with the first user's media account credentials on the playback device. To do so, the first user device can request a device identifier for the playback device, request and obtain a delegate token for the device identifier from the media service, and provide the delegate token along with media item information to the playback device. The playback device can then use the delegate token to request the media item associated with the first user's media access account.

Abstract: In some implementations, a system can be configured to manage groups of playback devices. For example, playback devices can be dynamically grouped in a variety of ways. Each playback device can store attributes that define the group to which the playback device belongs. Each playback device can send its group attributes to remote control devices and the remote control devices can determine groups of playback devices based on the group attributes. The remote control devices can then configure and present graphical user interfaces that represent the various groups of playback devices. In some implementations, a group of playback devices can be configured as a persistent group. For example, a pair of playback devices (e.g., wireless speakers) can store and send attribute data indicating that the pair of playback devices is a persistent group so that remote control devices can present and control the persistent group as a single device.
