TMService) can define its own unique trajectory identifier, and make broadcasting partner (selected broadcaster or whole broadcasters) can obtain these identifiers; Then, the broadcasting partner just can be embedded into these trajectory identifier in their broadcasting as metadata.
Metadata can also have the time aspect.For example, can change along with the change of theme with radio talk show metadata associated.By this way; PMD can receive the non-timeliness metadata related with talk show; This metadata is constant for the talk show of whole length, can also for example when in the talk show book being discussed, receive the timeliness metadata that is directed against book or when in the talk show famous person being discussed, receive the timeliness metadata to the famous person.
Station identification information also can be embedded in the broadcast data stream and by the tag extraction engine 130 of annex among Figure 1A 104 as meta-data extraction.Station identification information for example can comprise slogan language (tagline), program name, DJ's name of catchword, the platform of style, the platform of name, the platform of frequency, the platform at station, message, platform designated market area (DMA), the website URL of platform, the network member of platform or their combination in any of platform.In some embodiments, the broadcaster can register " the broadcasting partner " of media resource transmission service (for example, the media resource of Fig. 1 D transmission service 178) as.Service distributes a unique affiliate identifier to each broadcasting partner, and the broadcasting partner can comprise its affiliate identifier in the metadata of each track of its broadcasting.If the user gives the track tagging, then affiliate identifier can be recorded as the part of label, and works as the label that is write down when offering media resource transmission service 178, and service has received this affiliate identifier.Buy the user under the situation of tagging track, service can be used this affiliate identifier to decide to its broadcasting to cause the broadcasting partner who buys that remuneration or other credit are provided.(purchase to the tagging track further describes following.)
In some embodiments, metadata can also comprise the image related with track, for example special edition art, from the front cover of book or image, or the like (in Fig. 2, not listing).Metadata can also comprise the timestamp of the tagged date and time of indication track.In some embodiments, timestamp can be used to discern tagged track with station identification information.For example; When PMD102 (for example; Through shown in the master computer shown in Fig. 1 D 170 or Fig. 1 E wirelessly) when being connected to data network; The label information of being stored can be used for visiting the database of the server that is connected to data network, so that be identified in the media resource of at the appointed time playing on platform frequency or the name of appointment.
Label can also comprise can be or be not the out of Memory of the metadata that a receives part.For example, other identification information can include point, goes out point, the hardware of the annex of country code, medium type, program category, version information, seizure label or the ID of manufacturer, blog flow into information or any other appropriate information.If station identification information (for example, frequency) is not included in the metadata, then annex for example can be configured to through record its frequency of being transferred to when the track tagging this information to be added in the label.
In some embodiments, possibly require label to comprise the subclass of field among Fig. 2, and other field is optional.For example, in some embodiments, name, artist and album field possibly be enough for the most of tracks of unique identification, and all other fields can be set as optional.In some embodiments, the tag extraction engine 130 of annex 104 (Figure 1A) broadcast source that is configured to pack into provides each field of the label of enough metadata for it.In addition, the field that can obtain can also comprise " the unknown " field, tag extraction engine 130 can for this field pack into any annex that receives do not have identification metadata.Be described below, the unknown field of packing into makes PMD 102 can obtain Unidentified metadata, and might make PMD 102 with it communicating medium resource transmission service 178 (or other services) also can obtain this metadata.Media resource transmission service 178 (or other services) or PMD 102 possibly can explain Unidentified metadata.Therefore, label is not limited to any specific metadata fields combination.
In another kind of embodiment, except the metadata of extracting from broadcasting stream, perhaps replace it, annex 104 and/or PMD 102 can also catch the part of broadcasted content in label.Should be appreciated that label not necessarily comprises all possible identification information.
The amount and the type that can be used for being stored in the information of label can depend on broadcast source.In addition, different broadcast singal can comprise the information of dissimilar and/or different amounts.Fig. 3 is the table 300 that identifies the data field of some types of being supported by various known radio datas services, and wherein known radio data service for example has HD radio programming service data (" PSD "), HD radio station information service (" SIS "), HD radio station data directory (" SIG "), RDS and satelline radio program related data (" PAD ").Table 300 also identifies and possibly flow into the data field of supporting in (" EPF ") the employed business tie-up person of broadcasting partner by media resource transmission service.
Known or other the method for media resource of sign current broadcast also can be used in optional identification information and this area, comprises the combination in any of above describing method.Label information can be received by annex or directly received by PMD with multiple form, and the combination in any of sign track and/or broadcaster's (or other source) information can be included in the label.
In some embodiments, a plurality of networks can be used to provide broadcasted content and label information.For example, like the PMD of PMD among Figure 1A 102 and/or can be through receiving a plurality of communication with playing media broadcasting (for example, radio broadcasting, television broadcasting, call, or the like) simultaneously like the annex of annex among Figure 1A 104.The present invention can comprise the system and method that uses two or more those communication networks with integration mode.
Fig. 4 A and 4B illustration according to an embodiment of the invention wherein PMD use the system of two or more communication networks with integration mode.At first with reference to figure 4A, system 400 comprises PMD 402 and broadcaster 404.When having bandwidth constraint, system 400 can management of media information transmit (for example, medium track metadata).For example, in some cases, possibly expect provides a large amount of metadata together with media broadcast.But because bandwidth constraints, it possibly be unpractical doing like this.System 400 can solve this problem through using from sending the bulk information that is used for identical media broadcasting more than the bandwidth of a communication network.Some embodiment of the present invention through the different piece of utilizing different communication network to transmit information provide need bigger bandwidth transmission and download message (for example, metadata) and/or transmission and download message quickly.
For example, in one embodiment, broadcaster 404 can send media broadcast in a plurality of data segment A, B and C, the communication format coding that wherein each data segment can be different.Multiple communication format can be suitable for different communication network (for example, honeycomb, the Internet, terrestrial radio, satelline radio, ground cable, satellite cable, or the like).PMD 402 can be equipped with to be disposed for receiving according to the different communication form a plurality of communication sink 406a-c of a plurality of data segments.Controller 408 is suitably handled and synthetic a plurality of data segments, comes the complete transmission of reconstruct.
In optional embodiment of the present invention shown in Fig. 4 B, media broadcast person 410 can send media broadcast with the communication format of single type.PMD 412 can comprise resolver 414, wherein resolver 414 can receiving media broadcasting and signal resolution become a plurality of data segment A, B and C, wherein each data segment can be with the different communication format encoded.
What Fig. 5 was an illustration according to the embodiment of the invention uses the flow chart of the processing 500 of two or more communication networks with integration mode.In this embodiment, PMD comprises telephone capability (for example, cell phone or other mobile phone ability) and can in communication process, the medium transmission be gathered in other stagnant wakes (dead air).For example, replace when connecting when calling out and the stagnant wake of caller when interrupting, PMD can insert the medium transmission.In the medium process of transmitting, the user can be mutual with live media broadcast, for example gives the broadcasted content tagging through following description.
Processing begins (step 501) in idle condition.In step 502, start and call out.In step 504, the controller among the PMD can confirm whether calling connects.If no, then in step 506, PMD can broadcast by playing media, inserts it into the stagnant wake when connecting when calling out.During the period that media broadcast insert to be called out, the user can with media broadcast mutual (step 508), for example through giving medium track tagging with being described below, buying medium track and/or recording medium broadcasting.The user also possibly visit other option in interruption or Waiting for Call connection.
If controller confirms to call out on, then can confirm to call out and whether finish at step 510 controller.If no, then controller can after confirm whether calling interrupts (step 512).If interrupt, then in step 514, PMD can broadcast by playing media, when call interruption, is inserted into the stagnant wake.During the period that media broadcast insert to be called out, the user can with media broadcast mutual (step 516), for example through giving medium track tagging with being described below, buying medium track and/or recording medium broadcasting.Interrupt as long as call out also, PMD just can continue media broadcast is inserted calling.
Fig. 6 is illustration is used the processing 600 of two or more communication networks according to another embodiment of the present invention with integration mode a flow chart.In telephone call, the PMD with integrated phone ability (for example, cell phone or other mobile phone ability) can be inserted into media broadcast in the calling in response to user's request.For example, PMD can provide the visual indication of the current medium of being play by radio broadcasting that receive and can selectively Media Stream be inserted in the telephone conversation according to user's request.Then, the user just can give in progress media file tagging and share the copy of label with the people of the telephone wire other end or other people.
Processing begins (step 601) in idle condition.In step 602, PMD can be connected to call; For example, the user can operate the control to PMD, to send the calling of calling out or accepting to get into.In step 604, integrated equipment can the output medium trace information or the metadata (for example, the name of current played songs and artist) that provides with media broadcast.In one embodiment, integrated equipment has display, and metadata can offer the user on this display.
When the user was interested in the medium track of being play, the user just can drive user's input block of PMD, and the expectation (in Fig. 6, clearly not illustrating) of this medium track tagging, purchase or record is given in indication.Alternatively, the user can drive user's input block, indicates user expectation that media broadcast is inserted into (step 606) in the calling.If the user does not have indicative of desired that media broadcast is inserted in the calling, then supposition is called out and is not also finished (step 608), handles and continues output medium trace information (step 604) and wait for next user's input.
If user's indicative of desired is inserted into media broadcast in the calling, then in step 610, PMD begins media broadcast is inserted in the calling, makes all each side that are connected to calling can hear this broadcasting.The user can continue telephone conversation and mutual with media broadcast, for example through giving medium track tagging with being described below, buying medium track and/or recording medium broadcasting.Especially, if the opposing party of user or calling is interested in the specific medium track of being play, then user or this opposing party can give medium track tagging.
In step 612, the label of medium track can utilize the communication network (for example, telephone network or the Internet) of second type to send to the opposing party's phone.Recipient's phone not necessarily wants support media to broadcast---and promptly, recipient's phone need not have medium receiver parts or integrated PMD and telephone plant.If the not support media broadcasting of recipient's phone, then when media broadcast is play tagged medium in the future, receiver equipment can automatically be notified recipient user and the chance of listening to and/or buy the medium track is provided for recipient user.
In step 614, the user can indicative of desired stop media broadcast being inserted in the calling.If the user does not have indicative of desired to stop media broadcast being inserted in the calling, then handle and continue track is inserted into (step 610) in the calling, to allow the more multimachine meeting of user and broadcast interaction.In case user's indicative of desired stops media broadcast being inserted in the calling, PMD just stops media broadcast being inserted into (step 616) in the calling.Do not finish (step 608) if call out, PMD just continues the indication of output medium trace information (step 604) and products for further.Finish if call out, then handle turning back to idle condition.
Should be appreciated that said processing is an exemplary, and its variant all is possible with revising.The step of describing in order can executed in parallel, the order of step can change, and step also can be revised or merged.The combination of any network or network may be used to PMD or can be coupled to its annex transmission medium broadcasting and/or the information of being correlated with communicatedly.
Storage tags in PMD

(3) MarkedTracks key, its related value can be the arrays of one or more lower directory.Each lower directory can represent to be used for the label information of a particular track.Any one that label information can comprise that Fig. 2 for example is listed or whole fields.
As noted above, PMD 102 can communicate by letter through wired (for example, USB, FireWire, universal asynchronous receiver (" UART ")) or wireless (for example, bluetooth) passage with annex 104 in many ways.No matter the particular communication path how, PMD 102 can be through communicating by letter with data according to the agreement exchange command with annex 104.Protocol definition between PMD 102 and annex 104, send the form of message.For example, agreement can specify each message in the grouping with stem and optional pay(useful) load, to send.Stem provides essential information (for example, the length of start indicator, grouping and the order that will be handled by the recipient), and pay(useful) load provides any data with order association.In certain embodiments, order can be defined as and make that particular command is effective in a direction only.
Agreement can define a plurality of " enigmatic languages ", and wherein " enigmatic language " is to have each accessory class to support one group of related command of (or not supporting).In one embodiment, each order is by second the unique identification of byte of particular command in first byte of the enigmatic language under the marking command and the sign enigmatic language.Other imperative structures also can use.Each enigmatic language that does not need all PMD that all annexes or annex can be connected to all to define in the supported protocol.
In some embodiments, each annex 104 and each PMD 102 that is designed to can to cooperate each other can support to comprise " general " enigmatic language of the order of all this Device-Generals at least.This general enigmatic language can comprise makes PMD and annex can discern each other and verify that they are own and provide about they orders of the general information of ability separately, and each all supports other enigmatic language to comprise (if any).General enigmatic language can also comprise that PMD can be used for verifying the verification command of the hypothesized identities and the ability (otherwise perhaps) of annex, and if checking unsuccessful, then annex (or PMD) can be prevented from calling particular command or enigmatic language.
According to embodiments of the invention, can comprise " storage " enigmatic language (or other command group) that can be used to transmit order relevant and data with the bidding protocol that annex 104 is supported with the label of stores broadcast contents by PMD 102.In this embodiment, the order of storage enigmatic language allows annex 104 indication PMD 102 that label information (or metadata) is stored on its oneself the internal storage medium.
In one embodiment, the storage enigmatic language comprises to issue orders:
(1)GetPlayerCaps。Annex 104 can send to PMD 102 with this order, with the information of request about the player stores ability.
(2)RetPlayerCaps。PMD 102 can order and responds GetPlayerCaps order through sending it back this; The grouping pay(useful) load comprises institute's information requested.In one embodiment, ability information comprises: the overall size of PMD 102 internal storage medium; The maximum document size that allows; Can utilize single WritePlayerFileData order (following description) to write the maximum of the data in the memory; And sign is by the version information of the storage enigmatic language version of player support.Except above-described, perhaps replace it, also can comprise out of Memory.
(3)OpenPlayerFile。Annex 104 can send to PMD 102 with this order, and PMD 102 opens the file that is used for writing labels with indication.In one embodiment, this order is to send as the grouping of band non-NULL pay(useful) load.Pay(useful) load can comprise the value (being called " characteristic value " at this) that is used to indicate the file purpose.Therefore label file can be related with specific characteristic value.Characteristic value allows the storage enigmatic language to be used for the file of other type; Therefore, the storage enigmatic language is not limited to storage tags.
(4)RetPlayerFileHandle。PMD 102 can order and utilize RetPlayerFileHandle to order to annex 104 through (the XML catalogue file that for example, is used for label) response OpenPlayerFile that opens file provides the unique identifier that newly opens file (" handle ").Handle can be similar to the Unix filec descriptor.In one embodiment, handle is remained valid, and is removed or annex has been closed file (ClosePlayerFile of face order) as follows up to annex.It is helpful especially that the use of handle can be opened among the embodiment of a plurality of files at PMD 102 and/or annex 104 simultaneously; In some embodiments, can only open a label file, then handle can or can not use at every turn.
(5)WritePlayerFileData。After opening file, annex 104 can send this order to PMD102, so that add data (label that for example, is used for new tagged track) to the file of opening.Can comprise the handle of the file that will write, the side-play amount (position in the file) of beginning write data and the data that will write with the pay(useful) load of this order association.Annex 104 can be according to PMD 102 to the restriction of each WritePlayerFileData order data to each WritePlayerFileData order restricting data size, for example in RetPlayerCaps order (the above) by PMD 102 appointments.If label is greater than the restriction of appointment, then annex 104 can send a plurality of WritePlayerFileData orders, so that accomplish writing of label.Annex 104 can keep the tracking to side-play amount, for example avoids having covered previous label with new label.In some embodiments, file is a sequential write; That is, skew is started from scratch and is increased progressively according to the size of each write order.In other embodiments, sequential write is unwanted.
(6)PlayerAck。PMD 102 can send this order to annex 104, confirms that WritePlayerFileData order and any other do not need the storage enigmatic language order of specific response property information.Pay(useful) load comprises the identifier and the result phase designator of the grouping that is identified effectively, if wherein designator can be whether indication is write and successfully reached unsuccessful then be designated as the digital value or the bit pattern of what failure.For example, digital value can be defined as the specific status of fail of expression, lack among the for example mistake of annex 104 checking, the PMD 102 resource, invalid file handle, WritePlayerFileData divide into groups in excessive data volume, or the like.In certain embodiments, after having sent a WritePlayerFileData grouping, annex 104 is sending the PlayerAck that another WritePlayerFileData divides into groups or ClosePlayerFile divides into groups (the following stated) waits for that before indication completes successfully.Wait for that PlayerAck can help prevent mistake, the state of file is uncertain if for example order afterwards at the WritePlayerFileData of failure.
(7)GetPlayerFreeSpace。Annex 104 can send this order to PMD 102, to confirm the amount of free space in PMD 102 internal storage medium.

Should be appreciated that said command history is an exemplary, and its variant all is possible with revising.Also can support other order, for example send to order that the file from opening of PMD 102 reads and the order of returning data streams read that sends to annex 104.Therefore, for example, in writing process under the vicious situation, annex 104 can its data of attempting to write of retaking of a year or grade, to determine whether to have taken place mistake; So annex 104 just can send the WritePlayerFileData order or the close file of correction as required and open new file.
Should be pointed out that in some embodiments annex 104 can once be opened a plurality of files, is unique as long as distribute to the handle of each file.
Be used to catch the processing of label
In some embodiment of the present invention, PMD 102 communicates by letter with annex 104, catches label and label is recorded in the storage medium of PMD 102.
Fig. 8 is used for the illustration flow chart of the mutual processing 800 of user and media broadcast according to an embodiment of the invention.Any one of processing 800 or a plurality of step can be started by the controller (for example, carrying out the microcontroller or the microprocessor of suitable procedure code) of PMD among Figure 1A 102 or annex 104 and carry out.
Processing is in step 801 beginning, and here controller can start the user interactions program.In step 802, whether controller can be checked, maybe alternately to check with any additional of media broadcast.For example, whether wrong (for example, receiver 122 does not receive signal) or user indicate and stop the intention mutual with live media broadcast (for example, through turning off PMD 102 or annex 104) controller in can check system.If can not have additional alternately, then controller can withdraw from processing (step 804).
If additional is possible alternately, then in step 806, controller can wait for that the user drives user's loader, for example the user's input block 118 of PMD 102 or the user interface component 132 of annex 104 etc.Bide one's time waiting, it is " can be tagged " that PMD or annex can be indicated the content of the current broadcast of user.The quality of PMD can also (utilize display device, audio transmitting device etc.) indicating label.But some broadcasting can have less tagged information than other broadcasting, and that other broadcasting can have is very abundant, complete label can obtain.Any information that can obtain can be shown by some embodiment of PMD or annex.
When the user drove in these user's loaders, controller can confirm which function (step 808) user wants to start.In one embodiment, the user can buy current track (" BUY " function), gives current track tagging so that possibly buy (" TAG " function) later on or write down in a plurality of functions of current track (" REC " function) and select comprising.User's selection can wait to confirm according to the user's loader that for example when a plurality of user's loader is provided, drives, when the number of times or the time span of user's loader user's participating user loader when being multi-functional.
If selected the BUY function, then controller starts the purchase to current broadcast track.In step 810, controller can be confirmed PMD 102 or the annex 104 current data networks that whether are connected to, and wherein can have access to media resource transmission service through this data network.For example, with reference to figure 1D, computer system 170 is to be connected to the annex that media resource transmission service 178 is also broadcasted through network 174 receiving medias simultaneously through network 174.As another example, with reference to figure 1E, PMD 180 can wirelessly be connected to network and be connected to media resource transmission service, annex 104 receiving medias broadcasting simultaneously through this network.If PMD or annex are connected to data network, then in step 812, controller can be from the track of the current broadcast of media resource transmission service retrieval (perhaps about its further describing property information).
In one embodiment of the invention, even when PMD or annex networking, controller also can be given song or other audio track tagging of current broadcast.In this case, label can utilize the medium track of association is appointed as the designator storage of buying track.
In step 814, controller can be downloaded corresponding to the current media resource of playing track from media resource transmission service.In step 816, controller can store in the memory device 106 of PMD 102 for example the media resource of downloading or in the memory device of annex 104.Media resource can be stored as single file or a plurality of files (for example, as medium content file and the associated with corresponding identification information).If media resource is stored in the annex 104, then the user can be in downloading files into PMD 102 in the future.Similarly, if media resource is stored in PMD 102 or the annex 104, then the user can in the future with file from a device downloads or be transferred to another equipment.Controller can also add the audio track of downloading to the playlist that is stored in the predetermined or user's appointment on the PMD 102 for example.In some embodiments, the host computer system that computer system (for example, the computer system 170 of Fig. 1 D) is served as PMD 102 lets the user pass through the suitable software (iTunes that for example, is provided by Apple company that on computer system 170, carries out
TMManaging medium resource software) resource of managed storage on PMD 102.In this case, media resource can at first download to host computer system, and transmission then (for example, copy or mobile) is to PMD 102.
When controller was given the audio track tagging, controller can provide visual and/or audible feedback, comes for example to confirm label.As employed at this, when controller was given medium track tagging in the broadcasting process at the scene, controller extracted the information that can be used to identify institute's audio plays track from Live Audio, and will store the identification information that extracted for use in the future.Label can be stored in above any storage medium of mentioning, comprises the medium that is positioned on PMD 102 and/or the annex 104.The storage of label and between annex 104 and PMD 102, transmit label and will further describe following.
Refer again to step 808, indicate the TAG function if the user drives user's loader, then controller can be given the current track tagging of in media broadcast, playing in step 822.Be described below, when the user indicates the TAG function, before whether decision buys track, look back chance can for the user in the future about the information of tagging track.
During refer again to step 808, indicate the REC function if the user drives user's loader, then in step 824, controller can start a plurality of recording operations---manually record, plan record and charged timeout---one.In manually writing down, controller can write down the current one section broadcasting that receives.Recording start when receiving indication manually the user of record imports, and when receiving another user who indicates record end record end when importing.
In the plan record, controller can allow the broadcasting in one period future of user's indicating controller record.Controller for example can utilize, and EPG (electronic program guides) data provide schedule information to the user; Wherein the EPG data can be encoded in the broadcasting or (for example provide separately; Through second network shown in Fig. 4 A and 4B), and the user can select one or more broadcasting fragments that will write down based on these EPG data.Label can be stored as corresponding to each plan record.
In charged timeout, for example to be similar to the mode that media system was adopted that TiVo was provided by California Alviso, controller can " suspend " Live Audio.For example, controller can cushion the received transmission of scheduled volume continuously.When the user " did not suspend " transmission, controller can be exported the transmission of buffering repeatedly and continue the buffering Live Audio.Transmit in the process of playback in buffering, as stated, controller can allow the user to buy the audio track of current broadcast or give its tagging or manual recorded announce.As employed, when utilizing pause function, be counted as on-the-spot media broadcast to cushioning radioed playback at this.
In step 826, controller can store the media broadcast that is write down in above a kind of storage medium of mentioning into.
Fig. 9 is the flow chart of processing 900 that is used to catch and write down label according to the embodiment of the invention, Fig. 9 illustration use and the XML file of Fig. 7 of the above storage enigmatic language order.When annex 104 is connected to PMD 102, handle 900 beginnings (step 902).In step 904, it oneself also can carry out proof procedure to annex 104 to PMD 102 identifications.Step 904 can comprise confirms whether annex 104 is compatible about the storage enigmatic language each other with PMD 102; If they are incompatible, then handle 900 and may not use.
Suppose that PMD 102 and annex 104 are compatible about the storage enigmatic language each other, then annex 104 continues to open the file that is used for writing labels.For example, in step 906, annex 104 can send the GetPlayerCaps order, to confirm the storage capacity of PMD 102.PMD 102 can utilize the RetPlayerCaps order to return this information (step 908).Annex 104 can also be asked additional information before proceeding.For example, annex 104 can use GetPlayerFreeSpace to order to confirm to can be used in PMD 102 internal storage medium amount of space of writing labels.
In case confirmed the ability of PMD 102, in step 910, annex 104 just can send the OpenPlayerFile order, and the file identification that will open is a label file.As response, PMD 102 opens file.In one embodiment, PMD 102 can safeguard file (or catalogue) tree that is used to store its file, and opens in always can be in this tree identical file of label file, feasiblely locatees them easily in the future.In step 912, PMD 102 returns the RetPlayerFileHandle order that has the handle that newly opens file.
In step 914, initial information (for example, the top-level director piece 710 of Fig. 7) is write in the file.Be that initial information can be write when opening file by PMD 102 automatically among the embodiment of the file (for example, utilizing aforesaid characteristic value) that is used for label in file identification.In other embodiments, annex 104 can utilize one or more WritePlayerFileData orders to write initial information.
In case File Open is handled 900 and is just waited for next action (step 916).In this embodiment, relevant next one action is to the track tagging and withdraws from the tagging session.
Give the track tagging can be for example in response to taking place from user's request.For example, when playing track, the user can operate the user interface control of annex 104, indicates this track should tagging.As noted above, when PMD 102 or annex 104 can play track to user indication is can be tagged and can (for example, through showing available metadata) information about the available metadata amount be provided.
In step 920, annex 104 can extract metadata from broadcast data stream maybe will be as other data of label.For example, annex 104 can extract metadata from broadcast data stream, adds additional information (for example, the platform be transferred to of annex 104 or channel, annex 104 receive URL, the timestamp of data, the identification information of annex from it) and/or catch the expression of broadcasted content subclass.In optional embodiment, annex 104 can extract when receiving each track and cushion label information, has only when the user selects to the track tagging, and label information is just write label file.
In step 922, when the user asked the label of track, annex 104 was created the XML catalogue that is used for this new label lower directory piece of piece among Fig. 7 720 (for example, as).In step 924, annex 104 can send one or more WritePlayerFileData orders to PMD 102, the XML catalogue is write the file of having opened.In one embodiment, after creating the XML catalogue, annex 104 confirm the size of catalogues and relatively this size with capitalize most size (this full-size is obtained from player in step 908).Based on this comparison, how many WritePlayerFileData orders annex 104 need can be confirmed and can sequentially send these orders to PMD102.For each WritePlayerFileData that sends order, annex 104 can receive the PlayerAck order and can use the pay(useful) load of these orders to determine whether to have taken place any mistake, thereby can take suitable corrective action.For example, if mistake has taken place, then annex 104 can close file, open new file and attempt writing labels once more.As another example, write failure if lack the space in the memory device 106 owing to PMD 102, then annex 104 can remind user tag not transmit, and the space on PMD 102 is released.
After having write the XML catalogue that is used for new label, handle 900 and return step 916, wait for next user action.The XML file can stay open in during this period of time; Therefore, the label of any number can be write same XML file.In other embodiments, the file format except that XML or XML catalogue also can be used, and handles 900 and can be modified as and utilize any desired form writing labels data.
At last, whether the current tagging session of annex 104 detections should finish.For example, possibly reach maximum document size, the user just can start dismounting or the power down process of annex 104 from PMD 102 uncouplings, and perhaps the user can be arranged to annex 104 and/or PMD 102 not write down the state of label.As response, in step 930, annex 104 can send the ClosePlayerFile order, closes the XML catalogue file.In some embodiments, before sending the ClosePlayerFile order, annex 104 can be at first write to the XML file and is closed label (for example, closing among Fig. 7 label 730) at last.In other embodiments, PMD102 can through write close at last label then close file respond the ClosePlayerFile order that is used for label file.Under any situation, in step 932, in case closing of a file, PMD 102 just can send the PlayerAck catalogues to annex 104, confirms that file correctly closed.Handle 900 and finish (step 934) thereafter.
Other tagging is handled and also can be used.For example, Figure 10 is the flow chart that is used to catch and write down the processing 1000 of label in accordance with another embodiment of the present invention.Handling in 1000, PMD 102 can confirm whether track is wanted tagging and indicated annex 104 to create label.
When annex 104 is connected to PMD 102, handle 1000 beginnings (step 1002).In step 1004, it oneself also can carry out proof procedure to annex 104 to PMD 102 identifications; This step can be similar to the step 904 of above-mentioned processing 900.In step 1006, open label file.Label file among this embodiment resides in the storage medium of PMD 102, and is similar to the process of handling 900 step 906-912 and can be used to open label file.If annex 104 can not be controlled label is write in the label file in this embodiment, then when label file was opened, file handle may not turn back to annex 104.In step 1008, the stem branch is write label file by for example PMD 102.
In case label file is opened, handle 1000 and just wait for next action (step 1010).Next action can indicate the track should tagging; For example, the user can operate the user interface control on annex 104 or the PMD 102, indicates the track should tagging.If track should tagging, then in step 1012, PMD 102 can indicate annex 104 to create labels.In step 1014, annex 104 is created label from broadcast data.For example, as stated, annex 104 can extract metadata from broadcast data stream, add the expression of additional information and/or seizure content subset.In one embodiment, annex 104 can turn to tag format the XML catalogue or be suitable for writing other form in the label file.In step 1016, annex 104 can send to PMD 102 (for example, utilizing aforesaid one or more WritePlayerFileData order) with label.In step 1018, PMD 102 writes label file with label.Then, handle 1000 and can return step 1010, wait for next action.
If next action indication finishes current tagging session, then PMD 102 closes label file in step 1020, handles 1000 then and finishes (step 1022).(as stated, annex 104 also can detect the end of tagging session and indicate PMD 102 to close label file.) as in above-mentioned processing 900; Finishing the tagging session can take place under various situation; For example when reaching maximum label file size, when the user starts the state that annex 104 was handled or otherwise changed in dismounting, make no longer to receive or the record label.
Figure 11 shows the flow chart of tagging processing according to another embodiment of the present invention.In this embodiment, annex 104 can be created label for each track that in the tagging conversation procedure, receives, and PMD 102 selects to store which label.When annex 104 is connected to PMD 102, handle 1100 beginnings (step 1102).In step 1104, it oneself also can carry out proof procedure to annex 104 to PMD 102 identifications; This step can be similar to the step 904 of above-mentioned processing 900.In step 1106, open label file.Label file among this embodiment resides in the storage medium of PMD 102, and is similar to the process of handling 900 step 906-912 and can be used to open label file.Because annex 104 is not controlled label is write in the label file in this embodiment, therefore when File Open, file handle may not turn back to annex 104.In step 1108, the stem branch is write label file by for example PMD 102.
In step 1110, for example through detecting the variation in the broadcast metadata, annex 104 (or PMD 102) detects the next track in the broadcasting.If there is not next track (for example, off-the-air or annex 104 stop to receive broadcast data), then be described below, handle 1100 and finish.
When detecting next track, in step 1112, annex 104 is created label from broadcast data.For example, as stated, annex 104 can extract metadata from broadcast data stream, add the expression of additional information and/or seizure content subset.In step 1114, annex 104 can send label (for example, utilizing above-described one or more WritePlayerFileData order) to PMD 102.
In step 1116, PMD 102 determines whether storage tags; If storage tags, then PMD 102 writes label file in step 1118 with label.Then, handle 1100 and can turn back to step 1110, wait for next track.Handle 1100 and continue,, during this time do not have next track up to the tagging conversation end.In one embodiment, PMD 102 can detect the end (step 1122) of session and finish (step 1126) in processing 1100 and close label file (step 1124) before.Alternatively, as stated, end and indication PMD 102 that annex 104 also can detect the tagging session close label file.
Determine whether that storage tags (step 1116) can carry out in many ways.In one embodiment, PMD 102 can receive the current broadcast track of indication should be tagged user's input, and whether store the decision of the label that is used for current broadcast track can based on whether being when track is play, to receive this user's input.
In another embodiment, PMD 102 can support real-time log record pattern, wherein stores the label corresponding to each track that between broadcast broadcasted content session, receives.For example the user can not (perhaps briefly forget) playing in the broadcasting operation control indicate which track should tagged situation under, this is easily.The user can the trace logs of in the future look back playing and select interested those.In some embodiments; The log record pattern can be launched or forbidden by the user in real time; Perhaps log record can be behavior fully automatically, and the tag storage that automatically will be used for each broadcast session by PMD 102 is journal file (this journal file can be similar to label file).Journal file can be stored (for example, deleting them perhaps when the space allows up to the user) or storing predetermined time period indefinitely, perhaps can store some nearest journal files.Be used for confirming that other technology which label will be stored also can use.
In another embodiment, annex 104 can be collected label, is used for being forwarded to PMD102 in the future.For example, shown in Figure 1A, annex 104 can comprise its oneself tag memory areas 134.When stand-alone mode (that is, not being connected to PMD 102) is operated down, annex 104 can be with tag storage to tag memory areas 134.Label can be stored indefinitely, for example is sent to PMD 102 up to them.
Figure 12 can catch the flow chart with recording processing 1200 by the employed label of the annex with local label memory according to the embodiment of the invention.In this embodiment, whether pipe fittings is not connected to PMD (for example, PMD 102), and track can be by annex (for example, the annex 104 of Figure 1A) tagging.
When handling 1200 beginnings (step 1202), annex 104 determines whether to be connected to PMD102 (step 1204).If be connected to, then in step 1206, annex 104 can be write PMD 102 from tag memory areas 134 with any label of accumulation.For example, annex 104 can utilize the OpenPlayerFile order to open label file, utilizes one or more WritePlayerFileData orders that the label of each accumulation is write this document, utilizes ClosePlayerFile order close file then.In case the label that is accumulated is successfully write PMD102, annex 104 just can be removed label, discharges the space in the tag memory areas 134, so that store new label.
If in step 1204, be not connected to PMD 102 or in step 1206 all labels all write after the PMD 102, handle 1200 and continue to step 1208, play the broadcasting track at step 1208 place.For example, the user can be transferred to specific platform with receiver 122.Step 1208 can also comprise that detection is retained in the buffering area with current track metadata associated and with this metadata, confirms up to annex 104 whether these metadata should preserve.
In step 1210, confirm whether current track should tagging.For example, the user can touch the button or certain other control (perhaps user's loader 118 of PMD 102) of operating user interface 132, comes indicative of desired to give the track tagging.As stated, other standard also can this confirm in use (for example, whether launch all tracks automatic log record).If current track is not wanted tagging, then handle 1200 and can return step 1208, continue to play track, finally advance to next track, or the like.
If the result of step 1210 confirms that track should tagging, then handle 1200 and determine whether to be connected to PMD 102 (step 1212).If be connected to PMD 102, then in step 1214, tag transmits is to PMD 102, and as stated, PMD 102 can write label file memory device 106 with label.Above-described any technology can be used for writing labels.In some embodiments, PMD 102 can be label generation digital signature before writing labels, and this digital signature can be used to verify that the label data that is provided by annex 104 is not modified in the future.In some embodiments, PMD 102 can also comprise its oneself identifier (for example, the sequence number of PMD 102) in digital signature, and this identifier can be used to verify PMD identical with original stored whether that label is provided by label recipient subsequently.In another embodiment, annex 104 can open file, writing labels and create independent file with regard to close file, for each label of when being connected to PMD 102, writing in case confirm to write success.
If in step 1212, be not connected to PMD, then label should be write the tag memory areas 134 of annex 104.In some embodiments, if attempt writing PMD 102 failures, then label also can be write tag memory areas 134.In order to write tag memory areas 134, annex 104 can confirm at first whether (step 1216) has enough memory spaces can be used for storage tags in tag memory areas 134.If no, then in step 1218, annex 104 can remind the user that PMD 102 is connected to annex 104, and handles 1200 and return step 1202.If the user has connected PMD 102, then annex 104 just can be sent to PMD 102 with the label of accumulation, discharges its own this locality and stores, to support the storage of other label.
Refer again to step 1216, if it is available in tag memory areas 134, to have living space, then annex 104 is with tag storage (step 1220) in the tag memory areas 134.
In step 1222, after writing labels, before the further request that receives label, annex 104 can be waited for the beginning of next track.Therefore; Even user operation control and in single track process, repeatedly ask label; Annex 104 also with a writing labels once and avoids redundant label to fill up memory space (memory device 106 of its oneself tag memory areas 134 or PMD 102) in this embodiment.
For example, wherein do not use tagged another kind of operator scheme if annex 104 outages perhaps switch to, then step 1224 provides to withdraw from and has handled 1200 option.Do not withdraw from (step 1226) if handle 1200, then handle and can continue circulation, periodically inspection sees whether be connected to PMD 102 so that can the label of any accumulation be sent to it.
Should be appreciated that the various embodiment that said tagging is handled are exemplary, and variant and modification all are possible.The step that order is described can executed in parallel, the order of step can change, and step can be revised or merge.Order described here and command sequence can be revised.For example, in some embodiments, annex 104 possibly not indicate PMD 102 to open label file in conversation procedure, in this session, starts the tagging operation for the first time up to the user.In other embodiments, annex 104 can open file, writing labels and rapid close file, if the loss of data that makes a mistake and might cause when preventing that file from staying open.Therefore, annex 104 can be created the tagging file of any number in individual session, and each file can only keep a label.In another optional embodiment, annex 104 can be opened previous label file (supposing that maximum document size does not also reach) again, rather than is the new label file of each conversation establishing.Whether can perhaps be pursued for the tagged decision of track by PMD or annex makes by track ground conversationally.
Fuzzy label
Some embodiment also provides detection and the processing to " bluring " label.For example, depend on metadata and how to transmit, might be for given track, metadata streams possibly not be synchronously to begin the transmission unit data with the beginning of the content of this track definitely.As illustration, nearly five seconds skew that current HD radio standard allows arbitrary direction, the previous five of the metadata possibility morning of the track end formerly of therefore new track arrives or arrival in five seconds after new track begins.If the user asks label in this transition windows of ten seconds, then might current metadata not correspond to the actual track of wanting of user; This request is exactly the example of fuzzy request.
In some embodiments, when receiving fuzzy request, annex 104 is caught arbitrarily and label that all maybe be correct.For example, Figure 13 A and 13B are that annex according to the embodiment of the invention can be used for according to the fuzzy processing of request 1300 of transition windows identification of HD radio broadcasting and 1320 flow chart.Figure 13 A has described about confirming in last five seconds of track, whether to take place the step of label request, and Figure 13 B has described about confirming in five seconds at first of track, whether to take place the step of label request.
At first turn to Figure 13 A, handling 1300 can be in the use (step 1302) whenever of request label.In case the request label just uses the next enough seizure of label of postponing for a long time of five seconds timers (step 1304), to allow to detect the variation in the track metadata.In step 1306, when finishing in these five seconds, determine whether to receive new track metadata.If no, can infer that then the metadata when the request label is the metadata of expectation beyond all doubtly; Therefore, in step 1308, current track metadata is stored as label.
But, if in request five seconds behind the label, receive new track metadata, then might the user want to new track tagging, rather than when giving the request label its metadata just when preceding track (, being called " previous " track) tagging in order to represent.Therefore, in step 1310, be each establishment and the storage tags in previous track and the new track.With reference to figure 2; Two labels can be arranged to indicate their fuzzy each other values with its fuzzy label field, and be used for previous track label can with its press the button field be arranged to indication when receiving tagged request to track its metadata just when before.
With reference now to Figure 13 B,, handle 1320 can before giving last track tagging just in time, receive new track metadata (step 1322) use whenever.In step 1324, cushion previous track metadata, make its maintenance can let annex 104 obtain.In step 1326, use five seconds timers to come enough to postpone for a long time, to allow tags detected request in fuzzy time interval of request to the removing of previous track metadata.In step 1328, when finishing in these five seconds, confirm after receiving new metadata, whether to receive the label request.If no, then previous track data no longer needs and can be dropped (step 1332).
But, if in five seconds of reception new metadata, receive the label request, then might the user want, rather than give new track (when the user asked label, its metadata was proper preceding) tagging to previous track tagging.Therefore, in step 1330, be each establishment and the storage tags in previous track and the new track.Can its fuzzy label field be arranged to indicate their fuzzy each other values with reference to 2, two labels of figure, and be used for new track label can with its press the button field be arranged to indication when receiving tagged request to track its metadata just when before.
In this embodiment, annex 104 need not attempt solving ambiguity.Two labels all write down and finally are stored in the label file of PMD 102.Can point out the user to solve this ambiguity, for example when label file is read by managing medium resource and/or transmission system.
Visit to the tagging medium
In case label file has been write and closed, this label file just can be connected to various annexes or the device access of PMD 102 in the future, allows the user to look back thus and buys tagged track alternatively.In one embodiment, shown in Fig. 1 D, PMD 102 can be connected to be provided managing medium resource and/or the transmission service (iTunes that for example, is provided by Apple company
TMMedia management and transmission service, perhaps other existing managing medium resource and/or transmission service) master computer 170 of visit.Master computer 170 can be programmed to and make in the simultaneous operation process that PMD102 and media asset management system is synchronous, and any label file new or that upgrade is also read in master computer 170 automatic inspections.Can utilize about the communication of label file and to be similar to master computer 170 and to be used for checking and to manage by the agreement of the agreement of the renewal of other type files (for example, media file) of PMD 102 storages.Therefore, do not need to add enigmatic language introducing PMD communication protocol and just can manage reading label file.In some embodiments, the label file of being stored is just removed from PMD 102 after being handled and store by master computer 170.The label information that is used for particular track can continue to be stored on the master computer 170 long as far as possible, has for example deleted this information or has bought tagged track up to the user.In optional embodiment, PMD 102 can be with in one or more label files of tag storage on its own memory device 106; Label file can be stored indefinitely, has for example deleted the label that is included in wherein or has bought tagged track up to the user.
Figure 14 illustration according to the label playlist 1400 of the embodiment of the invention.Label playlist 1400 comprises the various attributes of tagging track, for example track name, artist, special edition, style and tagged date (although clearly do not illustrate, the wherein tagged date also can comprise the time).Some information in the label playlist 1400 (for example, tagged date) can be extracted from label.Out of Memory (for example, type) can be retrieved from the media resource transmission system.Track name, artist and album field can or utilize the trajectory identifier that for example is included in the label to retrieve from the media resource transmission system from tag extraction.Should be appreciated that track attribute listed among Figure 14 be exemplary and also not restriction.
In some embodiments, but label some or all attributes can be to clickthrough about the additional content of tagging track.For example, any one instance of " artist 1 " can make master computer 170 show the page of listing relevant information and/or artist's 1 other track in the click label playlist 1400.The user can also give the label playlist 1400 classification according to any listed attribute, for example through clicking suitable row head.
In one embodiment, each label file can be independent playlist and can discern different label files through for example date created.In another embodiment, all user's tagging tracks all are presented in the single playlist; Any copy track can be removed or visible terrestrial reference to be designated as be copy.The user can look back playlist and can select to preserve tabulation, from tabulation, deletes any or whole track and/or for example buy any or whole track from the media resource transmission system.
In some embodiments, playlist can also visually be given prominence to display label and be identified as fuzzy each other any instance (for example, the blurring trajectorie value of Fig. 2 is arranged to indicate the label of ambiguity), and can point out the user to select him to think tagged track.In order to help the user to make a decision, playlist can also comprise about which track when making this fuzzy request is considered to current designator; This information can be from for example Fig. 2 press the button that field obtains.Then, the user just can discern and delete undesired label.In some embodiments, the user also possibly want to select two fuzzy labels to keep; If the user selects like this, then the ambiguity mark can be removed from two labels.
The label playlist can be by master computer 170 through creating with media resource transmission service (for example, the media resource of Fig. 1 D transmission service 178) alternately.In other embodiments, for example need not connect (seeing for example Fig. 1 F) when just can transmit communication for service with media resource through master computer as PMD 102, PMD 102 can create and display label playlist on its oneself display device; Do not need master computer to create or watch the label playlist.
Figure 15 is the flow chart that can generate the processing 1500 of label playlist 1400 by controller (for example, carrying out the microcontroller or the microprocessor of proper procedure code) or master computer 170 usefulness of PMD 102 according to the embodiment of the invention.Processing 1500 automatically (for example, when label file is transferred to master computer 170) perhaps begins (step 1502) in response to user's request of listing the tagging track.In step 1504, controller reading tag file, this label file can be from the PMD 102 new label files that receive or by the master computer 170 previous label files that receive and store.For each label in the label file, extract unique trajectory identifier (for example, corresponding to Fig. 2 trajectory identifier metadata fields) in step 1506.In step 1508, controller can be sent to media resource transmission service 178 with trajectory identifier.In step 1510, media resource transmission service 178 uses trajectory identifier to retrieve the relevant information of track (for example, track name, artist, or the like) and message transmission that track is relevant to controller.
The information that track is relevant can comprise the information about any out of Memory of track of for example track name, artist name, album name, style or media resource transmission service 178 storages.The information that track is relevant can also comprise other information.In some embodiments, media resource transmission service 178 can provide uniform resource locator (" URL ") perhaps can be used for label playlist entry specific fields is linked to the out of Memory of related content.Therefore, for example, artist name can be related with the URL of the page of listing this artistical track that can pass through media resource transmission service 178 purchases.In other embodiments, the information that track is relevant can comprise and is used for some or whole related instruction and/or contents of Action Button this track and track playlist 1400.Therefore; For example; The information that track is relevant can comprise will carry out the instruction accomplished the purchase of track, about the out of Memory of purchase track (for example if the user drives " purchases " button 1404; The price of track), if perhaps the user drives " preview " button 1402 then the content of this track preview part that will play.
In step 1512, controller is utilized in the track relevant information generation label playlist that step 1510 receives.In step 1514, controller is presented to the user with the label playlist, for example through tabulation is presented on the display device.This display device can be the parts of master computer 170 or PMD 102 for example.In step 1516, the user can be mutual with label playlist 1400, for example preview, purchase or shared track etc.In step 1518, handle 1500 and finish.
Should be appreciated that said label playlist is an exemplary with handling, and variant and modification all are possible.The step that order is described can executed in parallel, the order of step can change, and step can be revised or merge.For example, in some embodiments, controller is carried out and handled 1500 can perhaps can be that the track relevant information of particular type is sent independent request for being used for the independent request of track relevant information transmission of each trajectory identifier; In other embodiments, single request can comprise a plurality of trajectory identifier.PMD 102 gives among some embodiment of label or label file digital signature therein, and master computer 170 can read digital signature related with label or label file and verification of data integrity; Can not get rid of outside playlist through the label of validation test.If label is rejected, then master computer 170 can be reminded the user.In also having other embodiment, master computer 170 or PMD 102 can be transferred to media resource transmission service 178 with label file; Media resource transmission service 178 can and can generate the label playlist that is used to be transferred to master computer 170 or PMD 102 in response to user's request for user storage label file (perhaps its part).
In some embodiments, the reading tag file can comprise error checking and/or data integrity checking.For example, as noted above, when label was write in the label file, they can be by PMD 102 digital signature; The reading tag file can comprise certifying digital signature, guarantees that label data is not changed or destroys.
The label playlist can comprise any combination of element, and element wherein includes but not limited to said those.In some embodiments, for each clauses and subclauses, some element can exist or not exist.For example, if the user has had this tagged track if tagged track can not obtain perhaps through the media resource transmission system, then buy option and can not launch, but track still can be listed.Be used for the additional option of list of labels and in the above U.S. Patent application of quoting the 11/210th, No. 172 (U.S. Patent application discloses the 2006/0235864th A1 number), describing alternately of user and list of labels.
The user is can be in many ways mutual with label information and media resource transmission service (for example, the media resource of Fig. 1 transmission service 178), to understand and to obtain tagged media resource.Figure 16 is the illustration flow chart of the mutual processing 1600 of user and media management and transmission system according to an embodiment of the invention, media management wherein and transmission system for example are similar to iTunes
TMCan be (for example although handle 1600 any one or a plurality of step by the controller of the PMD102 of Figure 1A; Carry out the microcontroller or the microprocessor of proper procedure code) or master computer 170 startups and execution, but annex 104 also can comprise making annex 104 can carry out circuit one or more in the following steps.
In step 1601, controller among the PMD 102 or master computer 170 can be opened the label file of being stored (this label file can be created as described above).In step 1602, controller can be confirmed the tag state (for example, label corresponding to still be the REC function about the described BUY function of Fig. 8, TAG function as above) of each institute's storage tags.If label is corresponding to BUY function (for example, being provided with if buy designator) as stated, then in step 1604, controller can be through network from the indicated media resource of media resource transmission service retrieval.In step 1606, controller can download to storage medium, annex 104 and/or the master computer 170 that is arranged in PMD102 with the media resource that retrieves.In some embodiments, download media resource can comprise that the affiliate identifier related with label (Fig. 2) sent to the media resource transmission serves.Media resource transmission service can use this affiliate identifier to increase credit for the broadcasting partner who makes the user can obtain this label information; For example, the broadcasting partner can receive a part of purchasing price of each label that causes the sale of tagging track.
In case downloaded, media file just can be stored (step 1608), and handles 1600 and can turn back to an A, to handle other label.
If controller is confirmed one or more labels corresponding to TAG function (for example, be not provided with and buy designator) in step 1602, then controller can be in step 1610 from media resource transmission service retrieval corresponding resource and/or the relevant information of resource.In step 1612, controller can allow the user to look back at least a portion of institute's retrieve resources or relevant information.In one embodiment, the resource that is retrieved can be used as and is similar to by iTunes
