Abstract: Examples described herein relate to transitioning a playback session between portable playback devices such as “smart” headphones, earbuds, and handheld speakers with playback devices of a zone-based media playback system. Exemplary techniques facilitate continuity of playback when transitioning between locations (e.g., from at home to on-the-go or vice versa) or between listening paradigms (e.g., personal or out-loud playback of audio content). An example implementation includes detecting a swap trigger, determining the source playback device(s) and target playback device(s), and performing a playback session swap between the source playback device(s) and target playback device(s).

The example method includes receiving, from a second audio information source, (i) a first message, and (ii) second audio information.

Abstract: Multiple aspects of systems and methods for voice control and related features and functionality for various embodiments of media playback devices, networked microphone devices, microphone-equipped media playback devices, and speaker-equipped networked microphone devices are disclosed and described herein, including but not limited to designating and managing default networked devices, audio response playback, room-corrected voice detection, content mixing, music service selection, metadata exchange between networked playback systems and networked microphone systems, handling loss of pairing between networked devices, actions based on user identification, and other voice control of networked devices.

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: Disclosed embodiments include network devices and systems of network devices. Some network device embodiments include (i) first and second network interfaces, (ii) a processor(s), (iii) tangible, non-transitory computer-readable medium, and (iv) program instructions stored on the tangible, non-transitory computer-readable medium that are executable by the at least one processor. Execution of the program instructions in some embodiments causes the network device to perform operations comprising (i) operating as part of a group with at least a second network device, (ii) receiving, via the first network interface, a message from a third network device, (iii) obtaining media content based on the message, (iv) transmit, via the second network interface, audio associated with the obtained media content to the second network device, and (v) causing video associated with the obtained media content to be output while the second network device outputs audio associated with the obtained media content.

Abstract: A computing device may broadcast a first message via a wireless interface while operating according to a first network topology. After broadcasting the first message, the computing device may receive the first message via a wired interface. Based on receiving the first message via the wired interface, the computing device may broadcast a second message indicating a second network topology via the wireless interface. Based on receiving the first message via the wired interface, the computing device may operate according to the second network topology.

Abstract: In general, user interfaces for controlling a plurality of multimedia players in groups are disclosed. According to one aspect of the present invention, a user interface is provided to allow a user to group some of the players according to a theme or scene, where each of the players is located in a zone. When the scene is activated, the players in the scene react in a synchronized manner. For example, the players in the scene are all caused to play a multimedia source or music in a playlist, wherein the multimedia source may be located anywhere on a network. The user interface is further configured to illustrate graphically a size of a group, the larger the group appears relatively, the more plays there are in the group.
