Abstract: A control device of media playback system receives a user command to initiate playback of video content and associated audio content and transmits a BLUETOOTH message based on the command to a video playback device. The video playback device receives the BLUETOOTH message, obtains the media content via a local area network (LAN), and determines an indication of when to begin playback of the media content. The video playback device transmits the indication to an audio playback device via the LAN and outputs the video content in lip-synchrony with playback of the corresponding audio content by the audio playback device. While outputting the video content in lip-synchrony with playback of the corresponding audio content by the audio playback device, the video playback device transmits timing information via the LAN to the audio playback device to maintain lip-synchrony with playback of the corresponding audio content by the audio playback device.

Abstract: Example techniques may involve guest access to a media playback system. A guest may use a guest control device, such as a smartphone or tablet, to control aspects of a host's media playback system. In addition, the guest may temporarily register their user account of a streaming audio service with the host's media playback system, which enables playback of audio content from that service by one or more playback devices of the media playback system. When the guest control device de-registers from the host's media playback system, retrieval of audio content from the streaming audio service is disabled.

Abstract: Embodiments are provided for enabling a user to control multiple media playback systems with a single mobile device. The mobile device may connect with a first or second media playback system based on receiving a first or second household identifier (HHID), respectively. If the mobile device receives both the first and second HHIDs, the mobile device may connect with either the first or second media playback system based on a priority of the two systems. If neither the first nor second HHIDs are received by the mobile device, a user may be prompted to add a third media playback system if the mobile device receives a third HHID. The user interface of the mobile device may receive an input to connect the mobile device to the third media playback system, and a connection may be established between the mobile device and the third media playback system.

Abstract: Networked devices are arranged to play content such as audio and video content in synchronization. A synching device receives a packet from an initiating device over a network. The packet may include an identifier of content to play, such as a URI, and an indication of when to play the content. A local clock time to play the content is determined based on a time of a local clock of the first device and the indication of when to play the content. The synching device obtains from a server the content based on the received identifier, and plays the content in synchronization with the initiating device based on a time on the local clock and the local clock time to play the content. In some embodiments, the synching device also adjusts a clock speed of the local clock reference to control rate of playback of the content.

Abstract: The examples provided herein involve multiple groups in a playback system. An example method involves, based on receiving one or more inputs defining a zone scene of a media playback system that comprises a plurality of zone players, defining configuration data corresponding to the zone scene, wherein the configuration data comprises an identification of at least a first zone player and a second zone player. The method further involves causing a remote computing device to store the configuration data and presenting a user-interface element that, when selected via the user interface, causes the zone scene to be invoked. The method additionally involves, in response to receiving an input indicative of a selection of the user-interface element, causing the remote computing device to invoke the zone scene at the media playback system such that the first zone player and the second zone player playback audio content in synchrony.

Abstract: The examples provided herein involve multiple groups in a playback system. An example method involves facilitating storage of a configuration of multiple zone groups as a multi-zone scene of a media playback system, the media playback system including at least a first zone group including at least two zone players and a second zone group, a user interface of a controller presenting at least an indication of (1) the first zone group, (2) the second zone group, and (3) a multi-zone group scene creation command.

Abstract: An example method includes linking a guest controller to a media playback system including a zone player with a playback queue. The playback queue includes information identifying media items to be played by the zone player. The media playback system provides the guest controller with a second access more limited than a first access granted to a local controller associated with the media playback system. The example method includes receiving, by the media playback system, a message sent from the guest controller, the message including a media service credential and an identification of a media item to be played by the zone player. The example method includes placing, by the media playback system, information identifying the media item from the guest controller in the playback queue. The example method includes retrieving media for the media item, by the media playback system, using the media service credential.
