The first and second subsets are different from each other. For example, each playback device is set to operate in two channel modes or stereo modes before being paired (eg, each playback device plays in both right and left channel audio). After pairing, one playback device is reconfigured to output the first channel (eg, right channel audio, not left channel audio), and the other playback device is the first. It is reset to output a second channel, which is different from the channel (for example, left channel audio, not right channel audio).

In another embodiment, three or more playback devices capable of outputting a plurality of audio channels independent of another playback device in the collection are selected and paired. After such pairing, each of the playback devices is set to output different audio channels from the collection. This embodiment is particularly useful for setting the type of television or cinema. A particular playback device of multiple playback devices is set to output in two channels or stereo mode at a time (eg when playing a song), and after pairing, the front right channel, front Output as center channel, front left channel, rear right channel, rear left channel, subwoofer channel, etc. (for example, when watching TV or a movie, or when listening to music containing more than two channels) Set,

In another embodiment, one of the paired playback devices, for example, processes the data for an audio item and divides the data into respective channels displaying a single soundtrack. The playback device transmits the divided channels to each of the other playback devices. The playback device synchronizes and plays back those characteristic channels to create a multi-channel listening environment. Alternatively, each of the paired playback devices processes the data of the audio item, or a portion of the data, to play them alone or one or more channels designed for each playback device.

In another embodiment, two or more playback devices can be grouped into a single or integrated playback device, and the integrated playback device is paired with one or more playback devices. Can be done. For example, two playback devices may be grouped into a first integrated playback device, or two other playback devices may be grouped into a second integrated playback device. The first and second integrated playback devices may be paired, for example. In certain embodiments, each playback device of the integrated playback device can be switched to integrated mode to change the equalization of one or more speaker drivers for any particular playback device. In addition, one or more other playback devices may be added to the integrated playback device.

In certain embodiments, the playback device is configured to output an audio channel and is paired with one or more other playback devices. In that way, the playback device is reconfigured to output a different audio channel. For example, the playback device may output the right channel in stereo mode, but after being paired with one or more other playback devices, it is reconfigured to output the rear, right channel in theater mode. May be good. The playback device may be paired with one or more other playback devices.

In certain embodiments, the playback device is configured to output multiple audio channels and is paired with one or more other playback devices. As such, the playback device is configured to output a subset of multiple audio channels associated with one or more other playback devices. For example, the playback device may be set to output in two-channel or stereo mode, but may be set to output the right or left channel after being paired with one or more playback devices. Good. The playback device may be paired with one or more other playback devices.

In certain embodiments, the playback device comprises a network interface, one or more speaker devices, an amplifier, and a processor. The network interface receives audio data on the network. The amplifier powers the speaker driver. The processor processes the audio data output through the speaker driver. The processor sets the first equalization of the output from the speaker driver according to the first type of pairing, and further sets the second equalization of the output from the speaker driver according to the second type of pairing. To do. The playback device can operate in either unpaired mode, paired mode, integrated mode, or group mode.

In certain embodiments, the controller is specifically configured to pair two or more playback devices, creating a multi-channel audio environment. That is, through the controller, the user can select which playback device to pair with. Once programmed, the playback device can operate in pair mode, for example, until released. In some embodiments, the controller is wirelessly connected to one or more playback devices. In other embodiments, the controller is wired connected to one or more playback devices.

According to certain embodiments, the pairing behavior of two or more playback devices is triggered based on a command from the user via a control interface (eg, a manual command creates a pair) or responds to an event. Triggered (for example, an automatic command creates a pair). Sample events detect changes in audio content (eg, audio content has two channel contents, which means it has three or more channel contents, and vice versa), identification. Period detection, detection of certain types of entertainment (eg, detecting whether a user is watching TV or listening to music), or any other programmed to create a pair with a playback device. Includes events. Event detection may be performed, for example, by a controller, one of the playback devices, or some other device.

According to certain embodiments, in an attempt to optimize multi-channel pairing, the playback device settings change the equalization of the playback device by varying the equalization of one or more particular speaker drivers. It may include either optimizing synchronization between a pair of devices. Examples of varying equalization are described further below.

The embodiments described herein can be combined with other embodiments, expressly and implicitly, as will be understood by those skilled in the art.
II. Environmental example

With reference to the figures, similar numbers in it can represent similar parts through several figures. FIG. 1 shows an example of configuration 100 in which a particular embodiment can be implemented. Configuration 100 can represent, but is not limited to, a residential, home, part of a business building, or a complex with multiple zones. A large number of multimedia players in three examples 102, 104, and 106 are shown as audio devices. Each of the audio devices may be installed or provided in one particular area or zone and is therefore referred to herein as a zone player.

As used herein, unless otherwise stated, one audio source or multiple audio sources is typically in digital form and can be transmitted or streamed over a data network. For ease of understanding of the illustrated environment of FIG. 1, configuration 100 is assumed to represent a home. However, it is understood that this technique is not limited to that environment of the application. Returning to FIG. 1, one or two zone players 102 and 104 may be placed in the bedroom, and zone players 106 may be placed or placed in the living room. Zone players 102, 104, and 106 are directly or indirectly connected to network 108. Further, the computer device 110 is shown to be connected on the network 108. In practice, any other device such as a home gateway device, storage device, or MP3 player can connect to network 108 as well.

The network 108 may be a wired network, a wireless network, or a combination of both. In one example, all devices, including zone players 102, 104, and 106, are connected to network 108 by wireless means based on industrial standards such as IEEE 802.11. In yet another example, all devices, including zone players 102, 104, and 106, are part of a local area network that communicates with a wide area network (eg, the Internet). In yet another example, all devices, including zone players 102, 104, 106 and controller 142, form an ad hoc network, eg, family identification: a family specifically named Karai family, eg, a family such as the Smith family. Distinguished from neighborhood settings similar to identification.

Many devices on network 108 are configured to download and store audio sources. For example, computer device 110 can download audio sources, such as audio related to music or video, from the Internet (eg, "cloud") or some other source, store the downloaded audio sources, and use the Internet or It can be shared locally with other devices on network 108. Either the computer device 110 or the zone players 102, 104 and 106 can be configured to receive streaming audio. As shown as a stereo system, device 112 is configured to receive an analog audio source (eg, from broadcasting) or extract a digital audio source (eg, from a compact disc). You can also convert analog audio sources to digital audio sources. According to certain embodiments, various audio sources may be shared between devices on the network 108.

Two or more zone players (eg, any two or more zone players 102, 104, and 106) may be grouped together to form a new zone group. Zone players and some combinations of existing zone groups may be grouped together. In one example, a new zone group is formed by adding one zone player to another zone player or an existing zone group.

In certain embodiments, there are two or more zone players in one environment (eg, the living room of a home). Instead of grouping these zone players and playing the same audio source in sync, these two zone players may be configured to play two different sounds on the left and right channels. In other words, the stereo effect of the sound is reproduced or enhanced through these two zone players, one left sound and the other right sound. Similarly, for 3-channel (or 2.1 sound effects) sound, even if three such zone players are reconfigured to have three speakers and the left and right speakers and subwoofer form a stereo sound. Good. More details on the reconfiguration of the zone player and the operation of these audio products are given below. A similar configuration with more than three channels (eg, 4, 5, 6, 7, 9 channels, etc.) may be applied. For example, configurations that use more than one channel are useful in television and cinema type settings, which allow video content, such as television and cinema formats, to be played with audio content that includes more than one channel. In addition, certain music may be similarly encoded in two or more channel sounds.

In certain embodiments, two or more zone players may be integrated to form a single integrated zone player. The integrated zone player may be further paired with a single zone player or yet another integrated zone player. The integrated zone player may include one or more individual playback devices. Each of the integrated playback devices is preferably set to integrated mode.

According to some embodiments, either grouping, integrating, and pairing can continue to be performed until the desired configuration is complete. Grouping, integration, and pairing operations are preferably performed through a control interface, rather than physically connecting and reconnecting speaker wires to, for example, individual separate speakers to create different configurations. In such cases, the particular embodiments described herein provide a more flexible and dynamic platform capable of providing acoustic reproduction to the end user.

It is understood that the techniques described herein are not limited to that environment of the application. For example, zones and zone players, embodiments described herein, include cars, personal watercraft, airplanes, amphitheaters, outdoors, along village or city streets, as well as homes, offices, gyms, schools. , Hospitals, hotels, movie theaters, shopping malls, shops, casinos, museums, theme parks, or any other place where audio content is played. Thus, of course, the embodiments described herein may be used in connection with any system or application for which multi-channel pairing is desired.
III. Example of playback device

Referring to FIG. 2A, an exemplary functional block diagram of the zone player 200 according to the embodiment is shown. The zone player 200 includes a network interface 202, a processor 204, a memory 206, an audio processing circuit 210, a module 212, and optionally an internal or external audio amplifier 214 and any speaker unit connected to the audio amplifier 214. Includes 218. The network interface 202 allows for data flow between the data network (ie, the data network 108 in FIG. 1) and the zone player 200, generally implements special rules (ie, protocols), and allows data to flow to each other. connect. One of the common protocols used on the Internet is TCP / IP (Transmission Control Protocol / Internet Protocol). Generally, the network interface 202 manages the compression of an audio source or file into smaller packets, which packets are sent or received on the data network and expanded to the original source or file. Further, the network interface 202 treats the address portion of each packet so that each packet reaches the correct destination or intercepts the packet destined for the zone player 200. Therefore, in certain embodiments, each packet contains an IP-based destination address as well as an IP-based source address.

The network interface 202 may include one or both of the wireless interface 216 and the wired interface 217. The wireless interface 216, also referred to as an RF interface, provides network interface functionality by the wireless means of the zone player 200 and provides communication protocols (eg, wireless standards IEEE802.11a, 802.11b, 802.11g, 802.11n, or 802. Communicate with other devices according to 15.1). Wired interface 217 provides network interface functionality by wire means (eg, Ethernet® cable). In one embodiment, the zone player includes both interfaces 216 and 217, and the other zone player includes only an RF or wired interface. Therefore, these other zone players communicate with other devices on the network or read the audio source through the zone player. Processor 204 is configured to control the operation of other components with the zone player 200. Memory 206 can be loaded with one or more software modules that can be executed by processor 204 to accomplish the desired task. According to one embodiment, for example, when a software module that implements the embodiments described herein is executed, processor 204 refers to a saved zone group setting that characterizes a zone group created by the user. Then, depending on the software module, the zone player 200 reads the audio source from another zone player or device on the network, synchronizes the players in the zone group, and plays the audio source as desired. According to another embodiment, the software module that implements the embodiments described herein creates a pair with two or more zone players to create the desired multi-channel audio environment.

According to one embodiment, the memory 206 is used to store one or more stored zone configuration files and can be read for modification at any time. Generally, the saved zone group configuration file is sent to a controller (eg, control device 140 or 142 in FIG. 1, computer, portable device, or television) when the user operates the control device. Zone group settings provide an interactive user interface and various operations or controls of the zone player can be performed.

In certain embodiments, the audio processing circuit 210 is like a circuit of an audio reproduction device, such as one or more digital-to-analog converters (DACs), audio preprocessing, audio enhancements or digital signal processors. including. During operation, when read through the network interface 202, the audio source is processed by the audio processing circuit 210 to produce an analog audio signal. The processed analog audio signal is then transmitted to the audio amplifier 214 and played back on the speaker. Further, the audio processing circuit 210 may include a circuit necessary to process an analog signal as an input, and the circuit generates a digital signal for sharing with other devices on the network.

Depending on the exact implementation, module 212 may be executed as a combination of hardware and software. In one embodiment, module 212 is used to store the scene. The audio amplifier 214 is an analog circuit that supplies the provided analog audio signal to drive one or more speakers in general.

It is understood that the zone player 200 is an example of a playback device. Examples of playback devices include those zone players commercially sold by Sonoz Incorporated in Santa Barbara, California. They currently include Zone Player 90, Zone Player 120, and Sonoz S5. The zone player 90 is an example of a zone player having no built-in amplifier, while the zone player 120 is an example of a zone player having a built-in amplifier. S5 is an example of a zone player having a built-in amplifier and speaker. In particular, the S5 is a five drive speaker system that includes two tweeters, two midrange drivers, and one subwoofer. When playing audio content via S5, the audio data on the left of the track is transmitted from the tweeter on the left and the midrange driver on the left, and the audio data on the right of the track is transmitted from the tweeter on the right and the midrange driver on the right. , And the monaural bus is transmitted from the subwoofer. In addition, both midrange drivers and both tweeters have the same equalization (or substantially the same equalization). That is, they are transmitted at the same frequency only from both different channels of audio. S5 is an example of a zone player having speakers, but the zone player having speakers is not limited to one having a specific number of speakers (for example, five speakers like S5), but rather one. It is understood that more than one speaker can be included. In addition, the zone player may be part of another device, which can serve a different main purpose than audio.
IV. Controller example

With reference to FIG. 2B, an example of a controller 240 that may correspond to the control device 140 or 142 of FIG. 1 is shown. Controller 240 can be used to enable control of multimedia applications, automation, and other complex ones. In particular, the controller 240 selects a plurality of audio sources available on the network and controls the operation of one or more zone players (eg, zone player 200) through an RF interface corresponding to the radio interface 216 of FIG. 2A. It is set to allow you to. According to one embodiment, the wireless means is based on an industrial standard (eg, infrared, wireless communication, wireless standards IEEE802.11a, 802.11b, 802.11g, 802.11n, or 802.15.1). .. If a particular audio source is played on the zone player 200, the image associated with the audio source, if any, may be transmitted from the zone player 200 to the display of the controller 240. In one embodiment, the controller 240 is used to synchronize the audio playback of one or more zone players by grouping the zone players within a group. In another embodiment, controller 240 is used to control the volume of each zone player within a zone group individually or together.

In one embodiment, the controller 240 is used to create a pairing with two or more playback devices, creating or enhancing a multi-channel listening environment. For example, the controller 240 may be used to select and pair two or more playback devices. In addition, the controller 240 may be used to turn pairing on or off. The controller 240 may be used to integrate the playback device and further set a particular playback device to integrated mode. Therefore, in some embodiments, the controller 240 provides a flexible mechanism for configuring a dynamic multi-channel audio environment. In some examples, pairing creates a multi-channel listening environment. In some examples, pairing improves the multi-channel listening environment by increasing the distance between devices. For example, two individual playback devices that are spaced apart from each other can provide the listener with multiple channel separations rather than audio from a single device.

The user interface of the controller 240 is a screen 242 (for example, a liquid crystal display screen) and a set of function buttons such as: "zone" button 244, "back" button 246, "music" button 248, scroll wheel 250, " Includes a set of "ok" buttons 252, a set of transport control buttons 254, a set of mute buttons 256, a volume up / down button 264, and a set of soft buttons 266 corresponding to the label 268 displayed on the screen 242.

The screen 242 displays various screen menus according to the user's choice. In one embodiment, the "Zone" button 244 activates the zone management screen, i.e. the "Zone Menu", which is described in more detail below. The "back" button 246 may perform different actions depending on the current screen. In one embodiment, the "back" button triggers the current screen display to return to the previous screen. In another embodiment, the "back" button denies the user's misselection. The "Music" button 248 activates the music menu and allows the selection of an audio source (eg, song) to be added to the music queue of the playing zone player.

The scroll wheel 250 is used to select an item in the list that is always displayed on the screen 242. If there are too many items in the list to fit on one screen, scroll indicators such as scroll bars or scroll arrows will appear next to the list. When the scroll indicator is displayed, the user may select the displayed item or turn the scroll wheel 250 to display a hidden item in the list. The "OK" button 252 is used to confirm the user selection on the screen 242.

There are three transport buttons 254, which are used to control the effects of the currently playing song. For example, the functions of the transport button include playing / pausing a song, fast-forwarding / rewinding, going to the track of the next song, or going back to the previous track. According to one embodiment, pressing one of the volume control buttons, such as the mute button 262 or the volume up / down button 264, activates the volume panel. In addition, there are three soft buttons 266, which can be activated according to label 268 on the screen 242. It is understood that in a multi-zone system, there may be multiple audio sources, each played on one or more zone players. The music transport features described herein should be selectively applied to one of the sources if the one corresponding to one of the zone players or zone groups is selected.

FIG. 2C shows an example of a controller 260 that may correspond to the control device 140 or 142 of FIG. The controller 260 includes a touch screen, for example, capable of navigating a playlist of many items that control the behavior of one or more players in which the user interacts with the controller. In one embodiment, as further shown in FIGS. 10A-10F, the user may interact with the controller to create a multi-channel audio environment, such as creating a stereo pair, or removing a stereo pair. It may be used to separate the audio environment. Other network-enabled mobile devices, such as iPhone®, iPad®, any other smartphone or network-enabled device, may be used as controllers to interact with multiple zone players in the environment. Or control (eg, a network computer such as a PC or Mac may be used as the controller). According to one embodiment, the application may be downloaded to a network-enabled device. Such applications can implement most of the above-mentioned functions on the controller 240 using an in-device navigation mechanism or touch screen. Those skilled in the art will appreciate the flexibility of the application and the portability to new types of specific portable devices subject to the detailed description herein.

FIG. 2D shows an internal functional block diagram of an example controller 270 that may correspond to the controller 240 of FIG. 2B, a computer device, a smartphone, or any other communication device. The screen 272 of the controller 270 may be a liquid crystal display screen. The screen 272 communicates with the screen driver 274 controlled by a microcontroller (eg, processor) 276 to issue commands. The memory 282 may load one or more application modules 284 that can be executed by the microcontroller 276 with or without user input via the user interface 278 to accomplish the desired task. In one embodiment, the application module is configured to allow selected zone players to be grouped into zone groups and to synchronize the zone players to one audio source. In another embodiment, the application module is configured to control the audio source (eg, volume) of the zone player in the zone group together. When the microcontroller 276 executes one or more of the application modules 284 during operation, the screen driver 274 generates a control signal to drive the screen 272, which is described below accordingly. Many display application-specific user interfaces.

The controller 270 includes a network interface 280 called an RF interface 280, which allows wireless communication with the zone player via its corresponding RF interface. In one embodiment, commands such as volume control or audio playback synchronization are sent via the RF interface. In another embodiment, the saved zone group settings are transmitted between the zone player and the controller via the RF interface. Controller 270 may control one or more zone players, such as 102, 104, and 106 in FIG. Nonetheless, there may be multiple controllers in each preferred zone (eg, a room or a room close to each other) and may be configured to control any one or all of the zone players.

In one embodiment, the user creates a zone group containing at least two zone players from a controller 240 that transmits a signal or data to one of the zone players. The signal received by one zone player is synchronized with the other zone players in the group so that all zone players are connected on the network, and in such a timely way of synchronization, within the group. All zone players play the same audio source or a list of the same audio sources, and no (or almost no) sound shifts or skips are heard. Similarly, if the user increases the audio volume from the controller, the signal or data that increases the audio volume of the group is sent to one of the zone players, along with the other zone players in the group to the same volume. Enlarge.

According to one embodiment, the application module is loaded into memory 282 for zone group management. When a given key (eg, "zone" button 244) is activated on controller 240, the application module runs on microcontroller 276. The input interface 278, which is connected to and controlled by the microcontroller 272, receives input from the user. The "zone menu" is displayed on the screen 272. Users can group zone players into zone groups by activating the "Link Zones" or "Additional Zones" soft buttons, or by activating the "Unlink Zones" or "Drop Zones" buttons. May start to be ungrouped. The details of the operation of the zone group are further described below.

As mentioned above, the input interface 278 includes a screen graphical user interface as well as a plurality of functional buttons. It should be pointed out that the controller 240 of FIG. 2B is not the only control device that can implement the embodiments. Other devices (eg, computer devices, handheld devices) that provide equivalent control functionality may be configured to carry out the present invention. In the above description, unless otherwise stated, it is clear that a key or button is commonly referred to as a physical button or soft button, allowing the user to enter commands or data.

One mechanism of zone players that are "connected" together for music playback links multiple zone players together to form a group. To link multiple zone players together, the user may manually link each zone player or room to each other. For example, there is a multi-zone system that includes the following zones:
Bathroom Bedroom Bedroom Study Dining Room Family Room Entrance

If the user wants to link 5 out of 6 zone players using the current mechanism, the user may start with a single zone and then manually link each zone to that zone. This mechanism can take a considerable amount of time. According to one embodiment, sets of zones can be dynamically linked together using commands. Using what is referred to herein as a theme or zone scene, a zone is set to a particular scene (eg, morning, afternoon, or garden) and the given zone grouping and attribute settings for grouping are automatic. Can be achieved.

For example, the "Morning" zone scene / configuration command would link the bedroom, study and dining room together in one action. Without this single command, the user would have to manually link each zone individually. Figure 3A provides an example of one zone scene, the left column shows the start of zone grouping-all zones are separated, and the right column is named after "Morning". The results of zone grouping are shown to create a group of three zones.

Further expanding this idea, the zone scene can be set to create multiple linked zones. For example, the scene creates groups of three separate zones, the downstairs zones are linked together, the upstairs zones are linked together within their own group, and the outer zones (in this case, the patio) Move into its own group.

In one embodiment, as shown in FIG. 3, the user defines a plurality of groups to be gathered at the same time. For example, an "evening scene" is desired to link the following zones:
-Group 1
○ Bedroom ○ Study ○ Dining room-Group 2
○ Garage ○ Garden Here, the bathroom, family room, and entrance should be separated from any group if they are part of a group before the zone scene is called.

A feature of a particular embodiment is that the zone does not need to be separated before calling the zone scene. In one embodiment, when called, a command is provided to link to all zones in one step. The command is in the form of a zone scene. After linking to the appropriate zone, the zone scene command can apply the following attributes:
Set the volume level in each zone (each zone has a different volume)
Mute / Unmute a zone Select and play specific music in the zone Set the music playback mode (shuffle, repeat, shuffle-repeat)
Set music playback equalization for each zone (for example, bass and treble)

A further extension of this embodiment is to trigger a zone scene command as an alarm clock function. For example, the zone scene is set to apply at 8:00 am. It can be set to automatically link to the appropriate zone, play a particular piece of music, and stop after a predetermined period of time. A single zone may be assigned to the alarm, but the scene setting as an alarm clock is a set of pre-defined audio (eg, favorite song, predefined play) with several linked zones in the scene. List) provides synchronized alarms that can be played for a specific time or period. If for some reason the scheduled music fails to play (eg, empty playlist, no connection to share, UPnP failure, no internet connection on internet radio station), the backup buzzer will sound. .. This buzzer is a sound file stored in the zone player.

FIG. 4 shows an example of a user interface 400 that may be displayed on the controller 142 or computer 110 of FIG. Interface 400 displays a list of user-configurable items to make the scene work at specific times. In the embodiment shown in FIG. 4, the list of items includes "alarm", "time", "zone", "music", "frequency", and "alarm length". "Alarm" can be set to on or off. When "Alarm" is set to on, "Time" is the specific time for setting the alarm to off. "Zone" indicates that the zone player is set to play the specified audio at a specific time. "Music" displays what is being played at a particular time. "Frequency" allows the user to define the frequency of alarms. "Alarm length" defines how long the audio will play. It should be noted that the user interface 400 is provided herein to show some of the features associated with setting alarms. Depending on the exact implementation, other features such as time zone for display, daylight saving time adjustment, time synchronization, and time / date format may also be provided.

In one embodiment, each zone in the scene may be set to a different alarm. For example, the "morning" scene includes three zone players, a bedroom, a study, and a dining room, respectively. After selecting a scene, the user may set alarms for the scene as a whole. As a result, each of the zone players will be activated at a specific time.

FIG. 5A shows a user interface 500 that allows the user to form a scene. The left panel shows the zones that can be used at home. The right panel shows the zones that have been selected and grouped as part of this scene. Depending on the exact implementation of the user interface, add / remove buttons may be provided to move zones between panels, or zones may be dragged along the panel.

FIG. 5B shows another user interface 520 that allows the user to form a scene. The user interface 520, which may be displayed on the controller or computer device, indicates the available zones in the system. Checkboxes are provided next to each of the zones so that the user can check the zones associated with the scene.

FIG. 5C shows a user interface 510 that allows the user to adjust the volume level of the zone player in the zone scene individually or collectively. As shown in the user interface 510, the "Volume ..." button (slider, shown in other possible forms) affects the volume of the zone player to which the user is associated when the zone scene is invoked. be able to. In one embodiment, when scenes are recalled, zone players can be configured to maintain whatever volume they currently have. In addition, the user can decide whether to unmute or mute the volume when the scene is recalled.
V. Provide examples of player themes or zone scenes

FIG. 6 shows a flowchart or process 600 that provides player themes or zone scenes for multiple players, where one or more players are located within a zone. Process 600 is shown according to one embodiment of the invention and may be performed in a module located in memory 282 of FIG. 2C.

Process 600 is started when the user decides to continue the zone scene at 602. Process 600 then moves to 604, where the user can determine which zone player to associate with the scene. For example, there are 10 players at home, and the scene is named after "Morning". The user may be provided with an interface for selecting 4 out of 10 players associated with the scene. At 606, the scene is saved. The scene can be saved to any of the members in the scene. In the example of FIG. 1, the scene may be stored in one of the zone players or displayed on the controller 142. During operation, the data associated with the scene contains multiple parameters. In one embodiment, the parameters include, but are not limited to, associated player and playlist identifiers (eg, IP addresses). The parameters may include the volume / tone settings associated with the scene. The user may return to 602 and set another scene as desired.

Given the saved scene, the user can activate the scene at any time, or set a timer at 610 to activate the scene. Process 600 can continue if the saved scene is activated at 610. At 612, when activating the saved scene, process 600 checks the state of the player associated with the scene. The state of a player means that each of the players must be in a responsive state in a synchronized manner. In one embodiment, player interconnections are checked to ensure that if there are such controllers in the scene, the players communicate with and / or with the controllers themselves.

Assume that all players associated with the scene are in good condition. At 614, the command is executed with parameters (eg, associated playlists and volumes). In one embodiment, data including parameters is transmitted from a member (eg, a controller) to other members in the scene to synchronize the player with the behavior set in the scene. The behavior allows all players to play songs on the same or different volumes, or play pre-saved files.
VI. Example of multi-channel environment

FIG. 7 shows an example of a configuration in which an audio source is played by two players 702 and 704 according to an exemplary embodiment. These two players 702 and 704 may be located in and around one location (eg, a hall, room, or nearby room) or may be designated to play two soundtracks each. Good. For example, an audio source may have left and right sound channels or tracks (eg, stereo sound). If, instead of grouping players 702 and 704 to play the audio sources together in sync, if each player 702 and 704 plays the same audio content at about the same time, pair the players 702 and 704 to play the audio source. Different sounds can be played in sync. As a result of pairing, the stereo sound effect can be simulated or enhanced via two players 702 and 704, for example for one player or no player.

In certain embodiments, each player of players 702 and 704 has a network interface, such as one or more speaker drivers (eg, if the player can play in stereo mode without pairing), as shown in FIG. 2A and the like. The example includes two or more speakers), an amplifier, and a processor. The network interface receives audio data on the network. One or more amplifiers power the speaker driver. The processor processes the audio source so that it is output through the speaker driver. The processor sets the first equalization of the output from the speaker driver according to the first type of pairing, and further sets the second equalization of the output from the speaker according to the second type of pairing. You may.

In one embodiment, the two players 702 and 704 are configured to output a plurality of audio channels that are independent of each other. For example, the respective players 702 and 704 may be configured to output audio content in stereo independent of each other. After pairing, one playback device (eg, player 702) is set to output a first subset of the plurality of audio channels, and the other playback device (eg, player 704) is configured to output the plurality of audios. It is set to output a second subset of channels. The first and second subsets are different from each other. In this example, after pairing players 702 and 704, player 702 can play the right channel and player 704 can play the left channel. In another example, player 702 can play the center channel in addition to the right channel (eg, television or theater mode), and player 704 can play the center channel in addition to the left channel. In a further example, the first and second subsets differ in that player 702 is playing channel right + center and player 704 is playing channel left + center. In yet another embodiment, after pairing, the player 702 plays all channels, except for certain bus frequencies, which can be played through the player 704 by using the player 704 as a subwoofer. be able to.

In another embodiment, a collection of three or more playback devices (eg, players 702, 704 and one or more other players) will output multiple independent audio channels of another playback device in the collection. Each is set. After pairing, each of the playback devices is usually set to output different audio channels from the collection. This embodiment is set so that a particular playback device among the plurality of playback devices is output in two channels or stereo mode at a time (for example, when playing a song), and after pairing, the front. Especially when set to output on the right channel, front center channel, front left channel, rear right channel, rear left channel, etc. (for example, when watching a movie or cinema), especially in the TV or cinema settings. It is useful.

In another embodiment, one of the paired playback devices (eg, player 702 or player 704) processes the data of the audio item, eg, substantially divides the data into channels, each of which is single. Represents a soundtrack and is played on one of the playback devices, then creates or enhances a multi-channel listening environment. In another embodiment, both playback devices (eg, players 702 and 704) may receive and process data for audio items, and each playback device outputs only the audio content specified for each player. You may. For example, player 702 may only play the left channel but receive both left and right channel audio, while player 704 may only play the right channel but left and right channel audio. May be received.

In another embodiment, two or more playback devices (eg, player 702 or 704) are grouped into a single or integrated playback device, and the integrated playback device (eg, integrated player 702 + 704) It may be paired with one or more playback devices. For example, two playback devices may be grouped into a first integrated playback device, and two other playback devices may be grouped into a second integrated playback device. The first and second integrated playback devices may then be paired to create or enhance a multi-channel listening environment.

In certain embodiments, a playback device (either player 702 or 704) that is set to output an audio channel is paired with one or more other playback devices that the playback device previously set. Is set to output an audio channel different from. For example, the playback device may be set to output the right channel in stereo mode, even after being paired with one or more other playback devices, and output the rear, right channel in theater mode. May be set to. The playback device may be paired with one or more other playback devices.

In certain embodiments, a playback device (eg, either player 702 or 704) that is configured to output multiple audio channels is paired with one or more other playback devices so that the playback device It is set to output a subset of multiple audio channels associated with one or more other playback devices. For example, the playback device may be set to output in two channels or stereo mode, but one or more other playback devices after pairing may output the right or left channel. It may be set. The playback device may be paired with one or more other playback devices.

According to certain embodiments, the pairing behavior of two or more playback devices is based on commands from the user (eg, manual commands) via the control interface, or on events (eg, automatic commands). Triggered in response. For example, a controller can be used by a user to create a pairing with two or more playback devices or to unpair with two or more playback devices. In another example, pairing is triggered by the audio content itself, a signal received from the source device, or some other predetermined event, eg, when an event is detected by the controller or playback device. Rings may occur. In addition, another device may be programmed to detect the event and provide a pairing signal to the controller and / or playback device.

In addition, different types from no-pairing (unpaired or unpaired) settings to pairing settings, or from one type of pairing (eg, pairing used in stereo or theater mode types). It is understood that the transition to pairing (eg, another pairing used in stereo mode or theater mode types) is all the various types of "pairing" that can occur with a particular embodiment. Will be done. Further, unpairing with a plurality of playback devices may be, for example, from pairing to no pairing, or from the first type of pairing to the previous type of pairing.

In the first example, the first type of pairing may include "no pairing" with another playback device, and the second type of pairing with one or more other playback devices. May include pairing. In the second example, the first type of pairing may include pairing with a second playback device, and the second type of pairing may include pairing with a plurality of playback devices. You may be. In a third example, the first type of pairing may include reproducing the two-channel sound via the speaker driver, and the second type of pairing may include reproducing the two-channel sound via the speaker driver. It has to reproduce only one of the sounds. In a fourth example, the first type of pairing may comprise reproducing the first audio channel via the speaker driver, and the second type of pairing may include the second type of pairing via the speaker driver. It may include reproducing two audio channels. In a fifth example, the first type of pairing may include reproducing the audio content via the speaker driver in stereo mode, and the second type of pairing may include reproducing the audio content via the speaker driver in stereo mode. May include reproducing audio content. In a sixth example, in the case of integrated mode, the first type of pairing may include reproducing the audio content via the speaker driver, and the second type of pairing may include reproducing the audio content through the speaker driver. It may be provided to reproduce the audio content via. It is understood that various changes or modifications can be made to the embodiments described above with the achievement of some or all of the advantages of the techniques described herein.

According to certain embodiments, the playback device settings change the equalization of the playback device by changing the equalization of one or more particular speaker drivers, synchronizing with a paired device. Includes either optimization. Changing the equalization of a playback device is to turn one or more specific speaker drivers on or off (or effective muting), or to change the channel output of one or more speaker drivers. It may include either changing the frequency response of the above specific speaker driver, changing the amplifier gain of any specific speaker driver, or changing the amplifier gain of the playback device as a whole.

In certain embodiments, changing the equalization of the playback device (eg, changing the equalization of one or more speaker drivers of the playback device) can affect frequency-dependent parameters. Examples may include frequency intensity adjustments, phase adjustments, and time delay adjustments in audio data. In addition, certain equalizations are first, such as those that attenuate high, medium, or low frequencies while allowing other frequencies to pass unfiltered (or substantially unfiltered). Type of pass filter can be used. The filters may be of different types or of different order (eg, primary filter, secondary filter, tertiary filter, quaternary filter, etc.). For example, the first equalization of the playback device may include using a first type of pass filter that modifies the output based on the first type of pairing, and the second equalization of the playback device may include. It may include using a second type of pass filter that modifies the output based on the second type of pairing. In this example, the first and second types of pass filters have one or different properties and / or behaviors that alter the equalization and sound behavior of the device.

For illustrative purposes, when two S5 devices are paired to create a stereo pair, for example, one S5 device may be set as "left" and the other S5 device may be set as "right". You may. In one embodiment, the user may decide which is left or right. In this setting, for example, left and right audio data may be transmitted to both S5 devices, but track left audio data is played from the S5 device set as left, and track right audio data is , Played from the S5 device set as right. In addition, the equalization of each S5 device is modified to reduce or eliminate certain structural or destructive interference. For example, one tweeter on each S5 device may be switched off or nearly muted. In certain embodiments, the crossover frequency for each driver may be further changed from the previous setting so that the two or more drivers do not necessarily output exactly the same audio data and are otherwise structured. Target and / or destructive interference may occur. In certain embodiments, the amplifier gain adjusts the playback device as a particular speaker driver and / or as a whole.

In operation, according to certain embodiments, a controller 706 (eg, controller 142 in FIG. 1 or 240 in FIG. 2B or a portable device) is used to initiate operation. Through the user interface, controller 706 causes player 702 to read the audio source if it is on network 708 (eg, the Internet or a local area network). Similarly, the controller 706 may also establish a communication session with the player 702 to send the requested audio source to a designated device (eg, another network device). In some cases, either one or both of the players 702 and 704 may have access to data indicating the audio source.

In certain embodiments, the module of player 702 is activated and processes data. According to one embodiment, it is divided into right and left soundtracks. One soundtrack is kept locally in one player, and other soundtracks are pushed or uploaded to other devices (eg, via ad hoc networks). If the right and left soundtracks play at the same time, or at about the same time, you get a stereo sound effect.

In another embodiment, some tracks are divided into, for example, television or theater modes. For example, the track may be divided into a center channel, a right front channel, a left front channel, a left front channel, a right rear channel, a left rear channel, and the like. Thus, one or more soundtracks may be kept locally in one player, and other soundtracks are pushed or uploaded to other devices.

In yet another embodiment, one player may process the data while the rest of the data is being transmitted to another player, or may hold one or more tracks locally. The receiving player may then process the data, keep one or more tracks locally, or send some remaining data to another player. This process, or the like, may continue until all tracks are held locally by the corresponding player's device.

In yet another embodiment, each player may receive and process data and play only the channel or channels designated for the player.

In certain embodiments, it is important to maintain good synchronization, as multi-channel audio content was originally intended, especially when pairing two or more independently clocked playback devices. Will be played back. According to embodiments, the message may be initiated from one device to another activated device and an acknowledgment may be sent back. When receiving an acknowledgment, the time delay of data transmitted from one device to another can be measured. The time delay is taken into account when synchronizing two players to play two separate soundtracks. In certain embodiments, when it takes 15 milliseconds or more to send a packet (eg, a packet relating to the SNMP protocol) to a playback device and receive a response, the timing contained within the packet, such as clock information. The information is discarded. If the packet is sent and received within 15 milliseconds, then the information from the packet is then used to coordinate playback, as needed.

For further details on synchronizing the actions of two or more independently clocked players, see "Operations Between Multiple Independently Clocked Digital Data Processing Devices," filed April 1, 2004 by the same application. Provided in US Application No. 10 / 816,217, which is incorporated by reference herein, entitled "Systems and Methods for Synchronizing."

FIG. 8 shows an example of a configuration of pairing with a plurality of players 802, 804, 806, 808, 810, and 812 in a theater-like environment according to an embodiment. The player 802 may operate as the front left channel, the player 804 may operate as the center channel, the player 806 may operate as the front right channel, and the player 808 may operate as the subwoofer. The player 810 may operate as the rear and right channels, and the player 812 may operate as the rear and right channels. In this example, players 802, 804, 806, 808, 810, and 812 are wirelessly connected on network 815 to receive and transmit data on the wireless network, at the wall or through other power sources (eg, batteries). Power can be obtained from the power outlet. Players 802, 804, 806, 808, 810, and 812 may be wired if configured as such in another embodiment. Controller 814 may be a network-enabled device, including, for example, a smartphone, tablet computer, laptop computer, desktop computer, or television.

In one embodiment, a designated player, such as player 804, receives multi-channel audio content from source 816. Source 816 may include audio and / or video content downloaded or streamed from the Internet, DVD or Blu-ray Disc, or from some other source of audio and / or video content. Player 804 divides into multi-channel audio and transmits each audio channel to its playback owner. For example, when a specific audio channel is designated for front and rear speakers, the content is wirelessly directed from player 804 to player 802 and the like. Players 802, 804, 806, 808, 810, and 812 play audio content synchronously to create a multi-channel listening environment. Further, when the source 816 provides the video content along with the audio content, the audio content is preferably played back in synchronization with the video content.

In another embodiment, each player of players 802, 804, 806, 808, 810, and 812 can be divided into one or more unique channels for playback. That is, all audio content, or a portion thereof, is transmitted to each player (eg, from source 816 or another playback device), and the player itself acquires its own data for playback.

In addition, players 802, 804, 806, 808, 810, and 812 may be reconfigured as described above and operated with many different settings. For example, players 802 and 806 may be paired to operate in stereo mode, while other players may be kept in sleep mode or switched off (player 808 is set so desired). If so, it is acting as a subwoofer and may remain in any particular setting). In another example, players 802 and 810 are integrated to output left channel audio, while players 806 and 812 are integrated to output right channel audio. In yet another example, some of the players 802, 804, 806, 808, 810, and 812 are integrated into a single player and paired with another playback device, for example in the next room. In a further example, players 802, 804, 806, 808, 810, and 812 are grouped and not paired if the audio content is music (eg, for movie content). These are just a few examples of settings. Many other settings are possible using the teachings described herein.

FIG. 9 shows a flowchart or process 900 for grouping multiple audio products, synchronizing and playing separate soundtracks to simulate a multi-channel listening environment. Process 900 is shown according to a particular embodiment and may be performed in a module located in memory 282 of FIG. 2D. To enable the description of Process 900, a stereo sound listening environment on the left and right channels is described. Those skilled in the art will appreciate that the description can be applied to other forms of multi-channel listening environments as well (eg, 3, 5, 7 channel environments).

Generally, there are a plurality of players controlled by one or more controllers, and these players are arranged in various positions. For example, there are five players in a house, three of which are placed in three rooms each, while two players are placed in a larger room. Therefore, these two players will be candidates to be paired to simulate a stereo listening environment, rather than simply playing audio synchronized from both in a grouped manner. In another example, there are four players in a large space and adjacent space, two pairs of players can be paired to simulate a stereo listening environment, and two players in one integrated pair are in groups. One (left) soundtrack can be grouped to play one (left) soundtrack, and the other two of the other integrated pair can be grouped to play one (right) soundtrack.

In either case, it is determined whether two groups of players or two players are paired at 902. If the players are not paired, process 900 will not be activated. It is assumed that two players from the group of players controlled by the controller are selected in 902 and paired. Process 900 proceeds.

At 904, the user may decide which player plays which soundtrack. Depending on the position of the user or listener with respect to the selected player, player or unit A is selected to play the left soundtrack, and another player or unit B is selected to play the right soundtrack. In another embodiment, the player itself (or controller) is configured to play which unit plays the right channel, and which unit plays the left channel, without any input from the user. It may be automatically determined whether or not it is.

According to one embodiment, the time delay for transmitting data between the two units A and B is measured at 906. This time delay can allow sound synchronization between the two units, with one unit receiving the processed soundtrack from the other. The user may continue to operate the controller and select a title (eg, an item from an audio source or playlist) at 910 to play on the two units.

Once the title is decided at 912, the title data is accessed. Depending on where the data is located, the controller may be configured so that one of the two units acquires or streams the data. In one embodiment, the controller or unit A initiates a request to a remote network device that provides or stores data. Assuming the authentication procedure is completed successfully, the remote device initiates uploading data to unit A. Similarly, if the data is stored locally in unit A, the data can be accessed locally without making the same request from the network. The processing module activates in unit A to process the data so that the data is received or accessed in unit A, effectively splitting the data into two streams on the soundtrack at 914. In another embodiment, each unit receives and processes the data and substantially separates the data into streams played by each unit.

At 916, one of the streams is uploaded from unit A to unit B via a local network (eg, an ad hoc network formed by all players controlled by the controller). The two units are each set to play the stream so that the stream is delivered, reproducing the sound of a single soundtrack at 918, respectively. At the same time, during synchronization, the two units create a stereo sound listening environment.

It should be noted that if significant, the delay time may be incorporated into unit A to delay stream consumption up to the delay time and synchronize with unit B. Alternatively, an unselected player may be used to process the streaming data for the title, set to supply two streams to a pair of players, and otherwise experienced by unit B. Make the delay time uniform.

10A-10F show an example of a screenshot of a controller for creating a stereo pair according to a particular embodiment. Screenshots are from a computer device used as a controller (eg, a tablet computer, laptop, or desktop). Those skilled in the art will appreciate that FIGS. 10A-10F may be readily modified for use in portable devices with network capabilities, such as, for example, the iPhone or iPod or other smartphones or other network-enabled devices. it can. In addition, the controller may exist as part of the player or be directly / indirectly connected to the player, so such screenshots may be modified accordingly-such. The controller has no network function and the player has a network connection.

FIG. 10A shows a graphic interface 1000 that can be displayed on the controller if the user wishes to create a stereo pair with two players in the stream. It is understood that the system may include more than one player. If a stereo pair is desired, then any two players in the system (players that can integrate one or both) may be paired, as described for the example in FIGS. 10A-10F. However, if pairing of two or more players is desired, for example, to create an environment in which it is possible to play two or more channel audio data, the graphic interface 1000 may be another option or multiple options. May include. For example, options may include "Create Movie Surround Sound Pairing", "Create Music Surround Sound Pairing", or "Create Dolby Pro Logic Pairing". Any written language may be used to properly indicate to the user the type of pairing in which it can be created. When choosing an option, the configuration wizard on the controller can help the user configure the system properly, and multi-channel discrete audio may be effectively implemented by the system.

Returning to FIG. 10A, the interface 1000 allows the user to initiate a stereo pair with a zone player named "ZPS5-Black". In certain embodiments, the system recognizes that the ZPS5-Black is part of a particular zone (eg, kitchen, family room, bedroom, etc.). The system may pair ZPS5-Black with other players in the same zone only, or the system may pair ZPS5-Black with other players in different zones (eg, adjacent zones). May be paired. Pairing players in different zones can be particularly useful if the open space is divided into two or more zones (eg, the open space includes a kitchen and a family room).

In addition, the system may be programmed to pair players from different zones to create different zones and reflect the players in pairing mode (eg, a single kitchen-family room for a pairing period). Zones may be created from kitchen zones and family zones during non-paired operating periods). In such embodiments, the user may be able to switch between zones or dynamically create new zones.

In certain embodiments, the screenshot of FIG. 10B can be displayed if other similar players can be paired. If the user wants to continue creating the pair, the user can select "OK". If not, the user can select "Cancel". In another embodiment, different players (eg, non-S5 players) are paired together. That is, if the players are designed to be paired, different types of players will be paired. To accommodate different player types, the equalization of one or more players is adjusted according to the situation, compensating for the number and size of speaker drivers used by one player for other players. May be good. In yet another embodiment, a list of players in the system (not shown) may be displayed, allowing the user to select two or more players to create a stereo pair. The list of players may be automatically determined by the system, for example, based on settings with a home, a particular position of a player in a room, or with other players in a room.

Returning to FIG. 10C, in this example, the user selects a zone player named "ZPS5-White" to be paired with "ZPS5-Black" to create a stereo pair. If so, the user can select "OK" to proceed with the pairing. If not, the user can select "Cancel". In certain embodiments, the ZPS5-White may be in the same zone as the ZPS5-Black.

May be activated by requesting to press the flashing mute button (or some other specified button). In one embodiment, blinking occurs on all the same speaker types. In another embodiment, blinking occurs on all speaker types that can be paired. After selecting the left speaker, the wizard screen asks the user to do the same for the right speaker. Preferably, only the speakers that can be paired as the right speaker are flashing to adequately narrow the user's choice.

Further, in one embodiment, as shown in FIGS. 3A and 3B, screen displays are provided to show the user all the players in the system and how they are grouped and named. If FIG. 3A is modified after the stereo pair is complete, the nickname of the stereo pair on display 1040 is highlighted and further displayed in FIG. 3A.

Similar graphics interfaces may be used to create pairs in an environment with more than one channel. For example, in a home theater environment, the system creates pairings by selecting players that are designed to act as front right, center, front left, rear right, and rear left, so that two or more separate. Players may be listed. Subwoofers can also be added to the list and incorporated into multi-channel pairing by the user.

As an example, similar to the description of the various embodiments above in connection with creating a stereo pair, the system may blink the indicator light on all associated players, and the configuration wizard will allow all speakers to flash. You can also ask the user to select "front left", then "front right", then "front center", then "rear left", then "rear right", etc. until they are in the right pair. Good. Preferably, only the speakers that can be paired as the next speaker are blinking, appropriately narrowing the user's choices.
