Abstract: An example method includes displaying zone names via a display interface. Each zone name represents a respective particular zone of a plurality of zones, and each zone contains at least one player configured for multimedia playback in that zone. The method includes displaying playback selections including a first playback selection that identifies first multimedia content for playback by the first zone and a second playback selection that identifies second multimedia content for playback by the second zone. The method includes receiving a command for a zone group to play one of the first playback selection or the second playback selection. The method includes transmitting a zone group configuration to one of the first zone and the second zone. The zone group configuration includes instructions to facilitate synchronized playback, between the first zone and the second zone, of the identified one of the first playback selection and the second playback selection.

Abstract: An example method includes, based on an adjustment to a first displayed volume control, instructing the first playback device to adjust playback volume level; based on an adjustment to a second displayed volume control, instructing the second playback device to adjust playback volume level; after sending the commands, instructing the first and/or second playback device to process an audio stream into a first and/or second channel and to reproduce a respective one of the first and second channel, wherein the grouped first and second playback devices provide multi-channel sound; and based on an adjustment to a third displayed volume control, instructing the first and/or second playback device to adjust a group volume level for both the first and second playback devices.

Abstract: Systems and methods for output of audio content are disclosed. An example first playback device includes a processor. The example processor is configured to at least process audio content to determine a portion of the audio content to be output by the first playback device based on a type of pairing of the first playback device and the audio content. The example processor is configured to at least determine, when the type of pairing pairs the first playback device with a second playback device to output the audio content, a time delay to facilitate sound synchronization with the second playback device. The example processor is configured to at least configure, based on the type of pairing and the time delay, the first playback device to output the portion of the audio content via an amplifier and a plurality of speaker drivers.

Abstract: Technology for grouping, consolidating, and pairing individual playback devices with network capability (players) to stimulate a multi-channel listening environment is disclosed. An example method includes receiving an audio signal containing a range of audio frequencies; amplifying, according to a gain parameter, the audio signal to be reproduced by at least one speaker. The example method includes automatically increasing the gain parameter to a higher gain parameter responsive to a determination that no more than a subset of the range of audio frequencies is to be reproduced by the at least one speaker. The example method includes amplifying, according to the higher gain parameter, the audio signal containing no more than the subset of the range of audio frequencies to be reproduced by the at least one speaker.

Abstract: An example method includes receiving, from a first playback device of a playback system, a message indicating a first zone configuration, the first zone configuration including at least a first zone associated with at least the first playback device and a second zone associated with at least a second playback device of the playback system; displaying, based on the first zone configuration, at least a first representation corresponding to the first zone and a second representation corresponding to the second zone; receiving an input to form a zone group including each playback device of the playback system; based on the input, transmitting to a third playback device of the playback system, a message indicating a second zone configuration, the second zone configuration comprising a zone group associated with each playback device of the system; and displaying, based on the second zone configuration, a third representation corresponding to the zone group.

Abstract: Techniques for managing a playlist in a multimedia system are disclosed. According to one aspect of the techniques, the playlist is structured to be able to include as many items as desired. To facilitate the manageability of such playlist, the playlist is built with a plurality of items. Each of the items is associated with metadata that includes information related to, for example, artist, album, genre, composer, and track number. The metadata for each item may be parsed, updated or logically operated upon to facilitate the management of the playlist. In another embodiment, each of the items is either a single item or a group item. A single item contains metadata of a corresponding source. A group item contains metadata of accessing other constituent items, which again may be single items or group items. As a result, the playlist can accommodate as many items as desired in a limited memory space without compromising the manageability of the playlist.

Abstract: In an example implementation, a method may involve sending a message that arranges a media playback system into a pre-defined state, wherein a first playback device is in a first zone having a first zone name, a second playback device is in a second zone having a second zone name, and a queue has a particular set of media items. The method may also involve detecting a trigger indicating a request to reset the media playback system. The method may further involve causing the media playback system to revert to the pre-defined state, wherein reverting may include assigning the first zone name to the first zone and joining the first playback device to the first zone, assigning the second zone name to the second zone and joining the second playback device to the second zone, and configuring the queue with the particular set of media items.

Abstract: Techniques pertaining to efficient scrolling are disclosed. One of the features of the efficient scrolling is the enablement of a search right at an appropriate item in a large list of items, thus avoiding going through the long list and wandering back and forth around a desired item. According to one embodiment, an indexing display is used. The indexing display includes a list of indexes, each corresponding to a group of items that sharing one or more common characteristics (e.g., a character or a kind). The indexing display is allowed first to be scrolled for a desired index. Once the desired index is confirmed, searching for a desired item in the large list starts at an item indexed by the desired index.

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.

Abstract: An example implementation may involve a control device displaying a control interface that includes an indication of one or more playable media items. The example implementation may further involve detecting input data indicating a selection of a particular instance of the given media item from among the one or more playable media items. Upon detecting the input data, the control device may identify a container of two or more media items, the container including the particular instance of the given media item and indicating a sequence for the two or more media items. The example implementation may also involve inserting the two or more media items of the identified container into a queue such that the two or more media items follow the indicated sequence within the queue, and causing one or more playback devices to initiate playback of the queue beginning with the given media item.
