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: Example techniques related to polices for media playback systems. An example implementation involves a computing system receiving data representing a request to play back first audio tracks on one or more first playback devices of a first media playback system. The first media playback system is associated with a first subscriber to a streaming media service and the first media playback system is physically located in a first commercial establishment. The computing system determines that the first subscriber is associated with one or more first subscriber policies of the streaming media service and sends instructions to play back the first audio tracks on the one or more first playback devices according to the one or more first subscriber policies of the streaming media service.

Abstract: A first zone player engages in synchronous playback of given audio content by obtaining the given audio content, generating and placing representative audio frames into a buffer, and transmitting the audio frames to a second zone player to play the given audio content in synchrony with the second zone player. After receiving a command to pause the synchronous playback, the first zone player prepares for a fast-resume by identifying a given audio frame and retaining at least some of the audio frames in the buffer for use during the fast-resume. The first zone player then initiates the fast-resume by determining a future resume time, transmitting an instruction to the second zone player to resume playback at the future resume time, and at the future resume time, resuming use of the audio frames in the buffer, starting with the given audio frame, to play the given audio content in synchrony.

Abstract: Methods and systems are provided for pairing electronic devices. One method includes generating a code sequence for pairing an electronic device with an application executed by a processor of a controller, the controller being remote to the electronic device, and the electronic device and the controller interfacing with a server via a network connection. The code sequence includes a configuration mode portion indicating a role for a user of the controller, an invitation sequence having invitation code for the user and a random code portion. The method further includes receiving the code sequence by the electronic device; validating the code sequence by the electronic device using a key data structure; and pairing the electronic device to the controller for enabling the application to monitor and command the electronic device.

Abstract: A playback device may be communicatively connected to a network device at a demonstration location. After connecting to the network device, the playback device may receive from the network device, a message indicating media content for playback by the playback device. In response to receiving the message, the playback device may play the media content, where playing the media content comprises modifying a default configuration of a demonstration mode. After receiving the message, the playback device may be disconnected from the network device. After disconnecting from the network device, the playback device may return to the default configuration of the demonstration mode.

Abstract: Embodiments are described herein that help allow for applying policies during playback of media. In one aspect, a method is provided that involves a computing device of a media playback system (a) receiving a request to playback one or more media items that are from a playlist associated with a controller application, (b) applying to the one or more media items one or more playback policies that are associated with the controller application, where a given playback policy restricts at least one aspect of playback of at least one of the one or more media items, and (c) causing playback of the one or more media items in accordance with the one or more playback policies.

Abstract: Systems and methods disclosed herein include, determining that a requirement exists to output a system response. In response to determining that a requirement exists to output a system response, (i) setting a system response volume for a first speaker associated with the first networked device and (ii) outputting a system response at the set system response volume via the first speaker associated with the first networked device.

Abstract: Audio content may be played back in synchrony with a member of a synchrony group based on playback timing information. While synchronously playing back the audio content, the playback timing information may be transmitted to the member of the synchrony group. The transmitted playback timing information may comprise a first timestamp. In response to a pause command, the synchronous playback may be paused prior to a time indicated by the first timestamp and a second timestamp. While the synchronous playback is paused and in response to a resume command, the member of the synchrony group may be instructed to update the first timestamp based on a new start time indicative of when the synchronous playback is to be resumed and update the second timestamp such that the updated second timestamp is synchronized with the updated first timestamp. The synchronous playback may be resumed based on the updated second timestamp.

Abstract: A first example playback device includes one or more processors and a non-transitory computer-readable medium storing instructions that, when executed by the one or more processors, cause the first playback device to perform functions. The functions include generating a mixed audio signal comprising one or more components of a first audio stream and one or more components of a second audio stream; and playing the mixed audio signal, where the one or more components of the second audio stream of the mixed audio signal played by the first playback device are played in synchrony with a second playback device configured to play the second audio stream. An example non-transitory computer-readable medium and an example method, both related to the first example playback device, are also disclosed herein.

Abstract: Techniques described herein may involve modification of playback based on the proximity of a user to a playback device. An example technique involves a device determining that a listener is within a given proximity of a first playback device and based on determining that the listener is within the given proximity of the first playback device, causing the first playback device to begin playback of first media and causing a second playback device to modify playback of second media.

Abstract: An example first playback device includes programming to perform functions including receiving a first request to associate with a first playback queue that is stored remotely from, and persists unassociated with, any playback device of the media playback system.
