In another embodiment, each of player 802,804,806,808,810 and 812 player can be distinguished The one or more passages opening their own are to be played back.In other words, by all audio contents or one part (for example, From source 816 or another playback apparatus) it is sent to each player, and player itself obtains the data of their own to carry out Playback.

Additionally, player 802,804,806,808,810 and 812 can be redeployed as above much not Operate in same configuration.For example, player 802 and 806 can be paired to operate in stereo mode, and other player It is maintained at sleep pattern or be closed that (player 808 can be continually maintained in any specific configuration (if such expect If configuration), this is because it is as subwoofer operation).In another example, player 802 and 810 can With merged and export left channel audio, and player 806 and 812 can be merged and export right channel audio.Another In one example, some in player 802,804,806,808,810 and 812 be merged into single player and with such as phase Other playback equipment pairing between next door.In another example, when audio content is music (with such as movie contents phase Right) when, player 802,804,806,808,810 and 812 is divided into one group but unpaired.These are only that some configurations are shown Example.By using teachings described herein, a lot of other configurations are possible.

Fig. 9 shows multiple audio products are grouped synchronously to play detached track and receives thus simulating multichannel Listen flow chart or the process 900 of environment.Process 900 is provided according to specific embodiment, and can be in the storage that will be located at Fig. 2 d Implementation procedure 900 in module in device 282.In order to promote the description to process 900, describe to have left passage and right passage Stereo listen to environment.Those skilled in the art are it will be clear that this description can be equally applicable to the many of other forms Passage listens to environment (for example, triple channel environment, Five-channel environment, seven channel environment).

Typically, there are the multiple players being controlled by one or more controllers, wherein, these players are located at many At individual position.For example, there are five players in house；Wherein three are located in three rooms respectively, and two players It is located at compared with big room.Therefore, this two players will be intended to be paired the candidate listening to environment to simulate stereo, and not It is from the audio frequency that two player plays are synchronous only in the way of being grouped.In another example, in larger space or adjacent There are four players in space, two pairs of players can be matched and listen to environment to simulate stereo, wherein, a conjunction And two players of centering can be grouped to play back (left) track, two other player of another merging centering can To be grouped to play back (right) track.

Under any circumstance, 902, determine two groups of players or two players are matched.If not to broadcasting Device is matched, then process 900 is not activated.Assume 902, select to from the multicast being controlled by controller Two players putting device are matched.Process 900 proceeds.

904, user may decide which player will play back which track.According to user or audience with respect to institute Select the position of player it is assumed that player or unit a are selected as playing back left track and another player or unit b are chosen For playing back right track.In alternative embodiment, player itself (or controller) can be in the input not being derived from user In the case of automatically determine which unit be configured to play right passage and which unit be configured to play left logical Road.

According to an embodiment, 906, the time delay of measurement transmission data between two unit a and b.This time Delay can promote the synchronous sound between two units, this is because one of unit is by the sound from another unit reception processing Rail.910, user can continue operational control device to select the title that will play back on two units (for example, from played column The audio-source of table or item).

Once determining title 912, with regard to the data to this title for the access needle.According to data location, controller Can be configured to make one of two units obtain or pour in (stream in) data.In one embodiment, controller or list First a initiates the request of offer or data storage to far-end networked devices.Assume that verification process (if any) successfully completes, Then remote equipment starts to upload data to unit a.Similarly, if data is stored locally in unit a, can not to In local IP access data in the case of network request packet.When receiving just in unit a or accessing data, 914, in unit Processing module is activated with processing data, thus being two track streams substantially by data separating in a.In alternative embodiment, Each unit can receive and processing data, thus being substantially the stream that will be play by corresponding unit by data separating.

916, via local network (ad-hoc network for example, being formed by all players being controlled by a controller) One of spread from unit a is to unit b.When stream is distributed, two units are configured in 918 difference playback stream, often One stream reproduces the sound of single-tone rail.Two units synchronously create together stereo listens to environment.

It should be noted that if time delay is obvious, can be incorporated to time delay in unit a with disappearing stream Consumption postpones this time delay so that synchronous with unit b.Alternatively, unselected player can be used for processing the streaming number of title According to, and be configured to provide two streams to this to player, thus the time delay that equilibrium otherwise will be experienced by unit b.

Figure 10 a to Figure 10 f shows the exemplary screen of the controller being used for creating stereo pair according to specific embodiment Sectional drawing.Screenshot capture is derived from computing device (for example, tablet PC, laptop computer or the desk-top calculating as controller Machine).Those skilled in the art are it will be clear that Figure 10 a to Figure 10 f can be easily modified to there is network capabilities just Use in portable device (for example, iphone or itouch or other smart phone or other have the equipment of network capabilities).This Outward, controller can exist as a part for player itself, or can direct/be indirectly coupled to player, therefore, These screenshot captures can be adapted accordingly because player will have network connection, and therefore this controller does not need There is network capabilities.

Figure 10 a shows can be in controller when user's expectation creates stereo pair using two players in system The graphical interfaces 1000 of upper display.It will be appreciated that this system can include two or more players.If it is desire to it is three-dimensional Sound pair, as the example with reference to Figure 10 a to Figure 10 f is discussed, then can be to any two player (therein in system Individual or both can be merge player) matched.However, if it is desired to match to more than two player, example As created the environment of the voice data that can play more than two passage, then graphical interfaces 1000 can include other option. For example, option can include " pairing of Making Movies surround sound ", " making the pairing of music surround sound " or " make Doby orientation Logic is matched ".Any descriptive language can be used for suitably indicating the type of the pairing that can create to user.Selecting choosing Xiang Shi, user can be helped to properly configure system for the Setup Wizard on controller so that system can be effectively realized leads to more The discrete audio frequency in road.
