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: 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: 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. The functions also include associating with the first playback queue and designating the first playback queue as an active queue of the first playback device. The functions also include receiving a second request to enter into a group with a second playback device that is associated with a second playback queue, entering into the group with the second playback device, associating with the second playback queue, and designating the second playback queue as the active queue of the first playback device. The functions also include receiving a third request to leave the group, and after receiving the third request, de-designating the second playback queue as its active queue.

Abstract: A playback device comprises a network interface configured to communicate with a network microphone device. A processor of the playback device comprises instructions, which when executed, cause the processor to receive a message associated with the network microphone device; and adjust a volume of audio content below a volume of content associated with the network microphone device based on the message.

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: 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.
