Abstract: Embodiments described herein may involve queue versioning. An example implementation may involve a playback device initiating playback of a queue including one or more first audio streams. A queue identification token stored in data storage represents a current version of the queue. The playback device receives, from a computing system, data representing instructions to add one or more second audio streams to the queue, the instructions including an indication of the one or more second audio streams and a first token representing an expected queue version. The playback device determines whether the expected queue version represented by the first token matches the current version of the queue represented by the queue identification token. If not, the playback device foregoes adding the one or more second audio streams to the queue.

Abstract: Embodiments described herein include systems and methods for providing a management interface for controlling multiple households. The management interface may be provided as an application on a mobile device or as an Internet webpage. An example implementation involves a device displaying representations of: a plurality of households; an indication of a selected household; one or more zones within the selected household; and a representation of media being played by a selected zone of the one or more zones. While displaying the representations, the device receives, from a server, data indicating updated information associated with the plurality of households; and, in response, updates the graphical display to display at least an updated representation of media being played by the selected zone.

Abstract: In one aspect, a computing device is configured to, while operating as a control device of a networked media playback system that includes a first set of network devices and a second set of network devices, (i) transmit a first message to each network device in the first set of network devices, wherein the first message comprises a command to, at a first time, temporarily disconnect from the computing device via a particular communication protocol, (ii) transmit a second message to each network device in the second set of network devices, wherein the second message comprises a command for the network device in the second set of network devices to, at a second time, test connectivity with the computing device; and (iii) after the second time, determine whether each network device in the second set of network devices was connected to the computing device.

Abstract: A network device is configured to (i) play back a media item indicated by a remote playback queue provided by a cloud-based computing system, (ii) receive an indication that a playback device is available for playback, (iii) display a now playing screen including (a) information identifying the media item, and (b) an icon that indicates that the network device is not in a connected state with any other network device, (iv) receive a first input selecting the icon, (v) in response to the first input, display a list of one or more available network devices including the playback device, (vi) receive a second input selecting the playback device from the list (vii) after receiving the second input, update the list to indicate that the playback device is selected for playback of the remote playback queue, and (viii) transfer playback of the remote playback queue from the network device to the playback device.

Abstract: Embodiments are provided for updating a playlist that has been added to a playback queue in response to changes to the playback queue. The playback queue may be associated with a zone of a network media system such that items in the playback queue are to be rendered by the zone. The playlist may include one or more items playable by the zone, and may be stored separately from where the playback queue is maintained. Embodiments are also provided for updating a playback queue in response to modifications to a playlist included in the playback queue.

Abstract: Based on a credential, an access level of a playback queue for a first control interface and a first subset and second subset of media items in the playback queue may be determined. Media items in the playback queue that were added via a second control interface may be included in the first subset. Media items that were added via a control interface different from the second control interface may be included in a second subset. Information may be provided which identifies the first subset of the media items in the playback queue and the second subset of the media items in the playback queue.

Abstract: Example techniques relate to cloud queue tombstones. An example implementation may involve a computing system receiving instructions to remove a particular media item from a playback queue. Based on the instructions, the computing system removes the particular media item from the playback queue and adds, to the playback queue, a tombstone indicator indicating that the particular media item has been removed from the playback queue. The computing system receives, from the media playback system, a request for a window of one or more media items from the playback queue. Based on the request, the computing system sends, to the media playback system, data representing a particular window of media items from the playback queue, wherein the particular window includes the tombstone indicator. The computing system detects a given tombstone removal trigger from among multiple tombstone removal triggers and based on the detecting, removes the tombstone indicator from the playback queue.

Abstract: Systems and methods for controlling multi-site media playback systems include, among other features, a computing system (i) receiving, from a first media playback device connected to a first network, a first registration message, (ii) in response to receiving the first registration message, assigning a system identifier and a first subsystem identifier to the first media playback device, (iii) receiving, from a second media playback device connected to the first network, a second registration message, (iv) in response to receiving the second registration message, assigning the system identifier and the first subsystem identifier to the second media playback device, (v) determining that the second media playback device is disconnected from the first network and connected to a second network, and (vi) in response to determining that the second media playback device is connected to the second network, assigning a second subsystem identifier to the second media playback device.

Abstract: A first connection state may be entered on a computing device. While the computing device is in the first connection state, actions taken on a playlist on the computing device may be applied to the playlist and not applied to a playback queue associated with a zone. An input may be received via the computing device, indicating a selection of the zone. In response to receiving the input, a second connection state may be entered. Entering the second connection state may comprise establishing a connected state between the computing device and the one or more playback devices. While the connected state is established, one or more actions taken on the playlist on the computing device may be applied to the playlist and transmitted, in a message to the zone over a network. The one or more actions may be one or more corresponding actions applied to the playback queue.

Abstract: While a first playback device is a member of a synchronous media playback group with a second playback device using a first media playback protocol, and after a particular playback setting is enabled using the first media playback protocol, the first playback device receives, from a media source device, a first media stream using a second media playback protocol. The first and second media playback protocols are incompatible. The first playback device determines that the particular playback setting is enabled and that the synchronous media playback group includes the first playback device and the second playback device. Subsequently, the first playback device (i) generates a second media stream based on the received first media stream, the second media stream including information for synchronous playback with the first playback device, and (ii) transmits, to the second playback device, the second media stream using the second media playback protocol.

Abstract: A first networked device may perform operations including receiving, from a media source device, a first media stream and a first media stream identifier. The first networked device may receive the first media stream via a wireless network connection. Operations may further include receiving, from a second networked device, a second media stream identifier that corresponds to a second media stream the second networked device is receiving from the media source device. Operations may further include determining a common stream characteristic between the first media stream and the second media stream and, in response to determining the common stream characteristic, grouping the second networked device with the first networked device. Operations may further include transmitting, to a controller device, an indication that the first networked device and second networked device are grouped.

Abstract: Example systems and techniques disclosed herein facilitate interoperability between different media playback systems referred to herein as a virtual line-in (VLI) media playback system and a native playback system. When a VLI session is created by a VLI sender, a first native playback device can join a VLI group as a VLI receiver. As a VLI receiver, the first native playback device receives audio content and playback commands from the VLI sender to facilitate synchronous playback with other VLI receivers. At the same time, this native playback device can concurrently operate as a native domain group coordinator of a native domain synchrony group. As the native domain group coordinator, the native playback device translates VLI domain audio, control, and timing signals into the native domain and distributes such signals to native domain group members. In this way, the native domain group members can synchronize their playback with the VLI group.
