Be combined in this Yankowski patent by reference, described several exemplary media recognition technologies, for example, based on the media identification technologies of using media identifier or " fingerprint " to inquire about media database.When medium (for example insert media playing apparatus, the CD-ROM of PC or DVD-ROM driver) time, can come local measurement, read or hint the media content characteristic according to the information in the medium toc region territory, such as orbit number or track offset (apart from the orbital distance of medium starting point).In the formula that generates the media content numeric identifier, the media identification business can be used these characteristics.Numeric identifier can be used for searching for local data base subsequently, or sends to carry out remote database search by computer network (such as the internet).If mate, then subsequently can be from database the match retrieval media information, and it is sent it back device.This method provides between its descriptive information fast in commercial pre-recorded medium and media database and has effectively communicated by letter.
Seen recent years from creating medium (for example CD-R and CD-RW) universal day by day.The user can create the audio frequency CD and the data CD of customization by using PC software according to the music content on their hard disk driver now.Similar with commercial CD, if the file of storing on the CD on form with the player compatibility, then Ding Zhi CD just can be able to use in all systems of play CD.Data CD can comprise the compacted voice file of MP3, Atrac3 or other code/decode format.These CD can combine with portable, the family of the corresponding demoder of compressed file code/decode format or automobile audio system on play.The data CD that the audio frequency CD of customization and user create is a class normally, and cannot use for the multi-user by commercial object.Therefore the existing media identification technologies that is designed to only to discern commercial media can't be discerned the audio frequency or the data CD of customization.
The audio file fingerprint is numerical value or other encoded radio of expression audio session record case.Track fingerprint can be codec, bit rate, record source/device and independent acoustical filter.Because its person's character, track fingerprint can with the media-independent of track record.Therefore, for example ' recording of the song ' Jingo ' of the Santana of Thebest of Santana ' and special edition ' Santana ' and be present in the compressed file such as MP3 on the hard disc of computer may have same fingerprint from special edition.Yet ' the same first song of recording in the performance at the scene on the Live at the Fillmore 1968 ' may have two different fingerprints from song ' Jingo ' and the special edition of the special edition of recording in the recording studio ' Santana '.When using the media identifier method to discern medium, can use fingerprint technique, discern content on the medium based on track one by one.
Have diversity owing to comprise the medium type of music, so specific embodiment can be in conjunction with media identifier and fingerprint method.Specific embodiment was attempted the person's character of identification medium earlier before attempting to discern.At medium is under the situation of non-commercial, can use the identifying of track one by one.In addition, can carry out the process of combination fingerprint and media identifier, with the media information in the location database.
Suppose to exist the connection of network (for example internet), then can from remote data base, retrieve the information of artist, track and other relevant special edition rapidly.Yet, for non-commercial media, incorrect information may be provided or not have information.Specific embodiment provides the identification to various commerce and non-commercial media.In a particular embodiment, extraction sound sampling from music file, and convert thereof into audio-frequency fingerprint.
As implied above, medium can classify as two kinds of in dissimilar any: commercial media and non-commercial media.Some examples of commercial media have: original commercial media, commerciality are dubbed medium and commercial reprint medium.Can discern the medium of production in enormous quantities by existing media identification technologies, such as the forgery of private or the medium that customization is created on a large scale, though be not with also can discerning that the traditional commerce mode is produced.In this article, refer to these medium and other medium above-mentioned with total term ' commercial media '.Some examples of non-commercial media have: the medium (being sometimes referred to as data medium) of the non-commercial duplicate of commercial media, non-commercial mixed-media and compressed format.
With reference now to Fig. 1,, it shows the exemplary medium identification system 100 that meets specific embodiment.Medium 100 comprises the computing machine 104 with local media database 108.Local media database 108 also can comprise fingerprint and metadata information, but to allow process local operation described here.Computing machine 104 has media player 110 (for example CD-ROM drive, DVD-ROM driver, CD-RW driver, USB port, miniature disk drive, tape drive etc.), this media player can be in the inside of computing machine 104, be coupled to computing machine 104 on perhaps connecting, and can be embodied as monomedia or multimedia device.The method of coupling media player 110 can be embodied as any connection mechanism, for example (is not limited to) numeral or dummycable, internet or other wired or wireless network service.Media player 110 is accepted any computer-readable media 112 (for example CD-ROM, DVD-ROM, CD-RW, CD-R, memory bar, hard disk or other magnetic media, mini disk, tape etc.).Computing machine 104 is coupled to network 116, such as internet or local or wide area network.Use network 116, computing machine 104 is coupled to media identification 120 and meta data server 124.Media identification 120 is coupled to fingerprint database 128 and media database 132, and meta data server 124 is coupled to metadata database 136 simultaneously.
Generally speaking, when (for example as local media database 108, it is physically approximate close, and can be directly connected to computing machine or playing device by wired or wireless connection) the same, fingerprint, identification and meta data server not when this locality (for example, when being positioned at remote location and connecting by network), at this fingerprint database 128, media database 132 and metadata database 136 are defined as remote data base.It should be noted that media identification 120 and meta data server 124 can be combined in the server.Equally, fingerprint database 128, media database 132 and metadata database 136 can be attached in the database.In addition, can create any of information placement and may arrange, so that as described here.Those skilled in the art based on what the consideration of this instruction it is also to be understood that are, for all or part media content is play, decoding, transcode or duplicate, computing machine 104 can be connected to the discrete device that uses these medium, or communicates by letter with this device.Understood this combination of device, server and database, now following method and apparatus open to discussion.
In a particular embodiment, use the method and apparatus of the media identification of medium 100 can use stage division to carry out media identification.Between in computing machine 104 and media identification 120 and meta data server 124 any, can use the communication session of progressively upgrading continuously.During first communication session, can transmit the minimum identifying information (if getable words) of identification media content; If during the first identification session, do not realize identification, then during the second communication session, transmit more information.Use progressively upgrade method of this classification, if first minimal information session success then can be saved communication bandwidth and recognition time.This stage division will more go through below.
In a particular embodiment, the method and apparatus that uses medium 100 to carry out media content identification can use disposable method to media content identification.Between in computing machine 104 and media identification 120 and meta data server 124 any, can use disposable communication session.During this disposable communication session, can transmit all identifying informations of identification media content.Use this disposable method, can save recognition time.Also will more go through hereinafter this disposable method.
Therefore, the medium that meets specific embodiment have the media content reader, according at least two in orbit number, distance and the track fingerprint on the medium that read by the media content reader programmed processor of creating media identifier, server, with programmed processor be connected to server interface, and server use the content information database of media identifier search.
With reference now to Fig. 2,, it shows illustrative non-commercial medium test 200.Non-commercial media test 200 expressions are to determining whether medium are embodiment of the test of non-commercial establishment.To commerciality with create resolving ability between (non-commercial) medium certainly, make media identification method and apparatus, and the method and apparatus of database maintenance and enhancing safer and effective.Also make data-base content more orderly to resolving ability commercial and that create certainly between the medium, and have more cogency.Along with more and more non-commercial (that is, creating certainly) medium appear at and are used for recognition data storehouse system, may cause endless collection (collection).If the establishment certainly that Database Systems do not attempt to file all is collected, then may require the inhibition large buffer memory in the given database.In addition, this big database may be very long for the search time of given data-base recording.By from given database, getting rid of, can reduce database search time and memory space greatly from creating medium.On the other hand, if database does not comprise the data-base recording of given commercial version, then may wish this commercial version is added in this media database.
Non-commercial media test 200 one of them that obtain among two results of present embodiment: " non-commercial establishment medium " or " can be the medium of the medium of commerciality or non-commercial establishment ".Can test based on any medium property of media specification (such as the Red Book audio frequency standard of audio frequency CD) regulation, this media specification does not come across on the recordable media of being managed by different media specification (for example orange paper standard of CD-R and CD-RW).In addition, to can be used for discerning it be not that commerciality is created to the recordable media attribute.Because the various attributes of firing medium, device and the recordable media (for example CD-R and CD-RW) of application, therefore might discern these medium and whether be non-commercial establishment.
Non-commercial media test 200 is since 204.208, from the media drive that is coupled to computing machine 104, read Driver Information.In this stage, use the method that for example reads multimedia order (MMC) collection, assemble information from driver.212,, determine whether driver is to write down driver (can write down the driver of recordable media) based in 208 information of assembling.Character according to driver will be carried out dissimilar processes.Can write down driver (such as standard CD-ROM), then forward 216 to if determine the driver right and wrong.
216, read information from medium self.Under the situation of non-R/RW driver, can discern the RW medium.In the present embodiment, the identification of CD-RW is based on the reflectivity of CD-RW, but also can use any test that can make this difference, comprises that the user manually imports.Because the person's character of CD-RW medium, its reflectivity is different from the reflectivity of other medium.Can use the pattern read data signal of driver to come perception reflex difference.Yet reflectivity is measured and can not be distinguished CD-R and commercial mark medium (at present) usually.Therefore, if medium are CD-RW, then the result that reads of reflectivity is ' non-commercial ', and if medium are different medium types, then the result is ' uncertain '.If test can be distinguished CD-R and commercial mark medium, then can improve this test, and remove above-mentioned uncertainty.When definite CD-RW was main body (subject) medium, this process can forward the fingerprint that extracts all tracks on the medium subsequently to, rather than searches for a track fingerprint.If determine that 220 medium are CD-RW, then forward 224 to, wherein medium are uncommercial, and process finishes 228.If do not determine that 220 medium are CD-RW, then forward 232 to, wherein medium are uncommercial or gyp, and process finishes 228.
If determine that 212 drivers are R/RW driver (for example CD-RW drivers), then forward 236 to, read information at this from medium itself.Under the situation of R/RW driver, at first verify that medium are closed or open 240.The medium of opening are non-commercial media, and forward 224 to, and process finishes 228.Notice that some is fired to use and allows to create audio session, and need not to close or finish medium itself.Because use when Pretesting and do not close medium itself, so these class medium will still be identified as uncommercially, but should not think that this situation is restrictive.If medium are closed, then be transformed into 244.Under the situation of R/RW driver identification recordable media characteristic, the medium of closing may still be identified as non-commercial media.These characteristics for example can be non-existent ATIP in the commercial media (pre-groove absolute time) area informations, or the existence of the subcode R-W on the audio frequency CD.If have atip information or subcode R-W information in the media 224, then these medium are " non-commercial establishment medium ", and forward 224 to, and process finishes 228.If can not determine that 244 medium are R/RW (not determining), then forward 232 to, wherein medium are non-commercial or gyp, and process finishes 228.
Therefore, meet specific embodiment and determine that whether medium are that the method for testing of non-commercial establishment medium comprises: determine whether driver is to write down driver, and if driver be to write down driver, determine then whether medium are to close medium.If medium are not to close medium, can think that then medium are non-commercial media, and whether be that non-commercial establishment medium are carried out the media identification process according to medium.In addition, if driver is to write down driver, then meet specific embodiment and determine that whether medium are that the method for testing of non-commercial establishment medium comprises: determine whether medium comprise rewritable media, and if medium are rewritable medias, can think that then these medium are non-commercial media.Meet specific embodiment and determine that whether medium are that the method for testing of non-commercial establishment medium also comprises: if driver is not to write down driver, then carry out the reflectivity test, determine whether medium are to rewrite medium, if and medium are to rewrite medium, can think that then these medium are non-commercial media.
With reference now to Fig. 3,, it shows the medium identification method 300 in 304 beginnings.308, from medium, read media characteristic, such as contents table (TOC) (if they exist).312, determine whether medium are the medium that comprise CD-DA (CDDA) or compressed format files (for example MP3).If medium are compressed format medium, then be presented at the information that provides in each file (for example ID3 label of mp3 file), and process finishes 320 316.As discussed below, also can assemble the definite orbit information of compressed audio media by forwarding 380 to from 316.For easy and clear for the purpose of, unclear in Fig. 3 this option is shown, but discuss below start from the situation that 380 all operations all is equally applicable to the compressed media content.If medium are not compressed format medium, then read orbit number on the medium and ' distance ' of computing medium content in 324 medium identification method 300.Because medium are inserted into device (for example CD-ROM of PC or DVD-ROM driver), thus can read from the toc region territory or all physical values of local measurement, such as orbit number or track offset (apart from the orbital distance of medium starting point).
' distance ' may be the not exclusive identifier of media content, and is the numeral of any suitable physical property of media content.For example (be not limited to), can be with any product of offset information available in the toc region territory as ' distance ', equally, any product based on bit calculates (such as the method for instructing in the above-cited Yankowski patent) and also can be used as suitable distance metric value.For distance calculation many other possibilities are arranged, such as the particular value of toc region territory stored and, long-pending, difference or other mathematical combination.Can use any suitable calculating.After considering the disclosure, to those skilled in the art, determine that several other mechanism of the distance used are conspicuous in database search.
328, medium identification method 300 takes the fingerprint one of them track (for example first track on the medium) from medium, and 332, creates the media identifier that is used for data base querying.Media identifier comprises on the distance of orbit number on the medium, medium and the medium fingerprint of one of them song/track herein.Hereinafter will provide more details about the media identifier certain preferred embodiment.In this, be enough to realize the establishment of media identifier.
336, use the media identifier of creating 332, carry out the inquiry of local media database 108.If can the local information that obtains relevant media content, then information be present in the medium/content district on the device.340, can show this information subsequently, and process finishes 320 to the user.If there is not this information in this locality, then carry out non-commercial media test 200 discussed above 344.
Result according to non-commercial media test 200 judges 348.If determine that by non-commercial test 200 medium are commerciality that create or undetermined (as discussed above), then forward 352 to, and media identifier is sent to media identification 120 and meta data server 124.356, media identification 120 is carried out medium content identification process based on media identifier subsequently, and meta data server 124 carries out the metadata retrieval process, hereinafter will be at these two processes of Fig. 6 more detailed description.360, receive response from media identification 120 and meta data server 124.If determine to identify these medium 364, then forward 368 to, at this to user's display media.As hereinafter discussing, might a plurality of couplings will be discerned by medium content identification process at the media identification process.If can discern a plurality of couplings, and it is presented to the user as media list, then the user in the suitable identification of 372 process receiving media contents selects.376, any metadata that meta data server 124 is found is presented to the user, and process finishes 320.
If determine that by non-commercial media test 200 these medium are non-commercial establishments,, then need not carry out further data base querying subsequently in the media identifier that 332 usefulness are created if perhaps do not identify these medium 364 348.On the contrary, from all tracks, extract track fingerprint, and as hereinafter discussed in detail, modification/extended medium identifier is to comprise the fingerprint of all tracks on the medium 380.384, the media identifier of expanding is sent to media identification 120 and meta data server 124.388, media identification 120 is carried out track identification process based on extended medium identifier subsequently, and meta data server 124 carries out the metadata retrieval process, hereinafter will more go through this two processes at Fig. 7.392, receive response from media identification 120 and meta data server 124.Show information and the metadata information that all tracks are retrieved 396 to the user, and process finishes 320.
Therefore, the method for medium content identification that meets specific embodiment can comprise and carries out the non-commercial media test.If media content is non-commercial content, then process is extracted the fingerprint of all tracks of media content from medium, creates the media identifier comprise all track fingerprint of media content, and with this media identifier search database.This method also can comprise: if can not determine media content is non-commercial content, then from medium, read and information that calculating is relevant with media content, and create media identifier according at least two in the orbit number on the medium that from medium, calculate, distance and the track fingerprint.
Equally, the method for medium content identification that meets specific embodiment comprises: read the information relevant with media content from medium, create media identifier, and use this media identifier search information in local media database, and create local search results.If in local media database, there is not information, then this method also comprises: carry out the non-commercial media test, if and the non-commercial media test is uncertain, then this media identifier search remote data base is used in request, and receives the first long-range search result from remote data base.If media content is non-commercial content, if perhaps in remote data base, there is not information, then this method also comprises: the fingerprint that extracts all tracks of media content from medium, establishment has the extended medium identifier of all track fingerprint of media content, this extended medium identifier search remote data base is used in request, and receives the second long-range search result from remote data base.Can show arbitrary Search Results above-mentioned to the user.
In some cases, system design can provide media content information at any time based on finger print information.In these cases, 380 can follow 336, need not to carry out " non-commercial establishment " test.The example of these situations includes, but is not limited to: such as the validity of the express network access of DSL, cable modem, optical cable or fast wireless network, such as the data consistency based on fingerprint, accuracy, fingerprint database in the system that performance penalties is not provided strengthen, preferential fingerprint database uses under the situation of design simplification demand.
With reference now to Fig. 4,, it shows as the possibility embodiment of media identifier 400 in 332 media identifier of creating.The data segment that comprises the orbit number data field exists as 404.The data segment that comprises the range data district exists as 408.The data segment that comprises the indication media identifier and whether be the data field of extended medium identifier exists as 412.Under the situation of medium content identification process, such as the process of describing at Fig. 6 hereinafter, it is not extended identifier that this identifier will be indicated in data field 412.Comprise the get on the right track data segment of data field of fingerprint number of indication medium and exist, to help identifying as 416.As discussed above, the track fingerprint of using in identifying needs not to be first track on the medium.Which track track fingerprint number identification selects carry out the fingerprint processing from media content.The data segment that comprises the data field of track fingerprint exists as 420.Usually, media identifier can comprise in orbit number, distance and the track fingerprint two or more multinomial (if use track fingerprint, then adding the relevant data segment of supporting, such as orbit number), to allow search.Under the prerequisite that does not break away from the embodiment of the invention, can rearrange the order of data segment.Based on the consideration of current instruction, those skilled in the art also can expect other data configuration.
Therefore, meet the computer data signal that specific embodiment is embodied as bit stream and have following wherein two data segments at least: the data segment of content distance calculation and the data segment of expression track fingerprint on the data segment of content tracks number, the presentation medium on the presentation medium.
The content that is noted that Fig. 4 shows the concept structure that is included in information in the media identifier.This also means restriction, and media identifier itself can be the numeral of information, is not limited to the presentation format that the application provides.
With reference now to Fig. 5,, revises and of suitable extended medium identifier that comprises all track fingerprint may be shown as media identifier 500 by embodiment 380.Data segment 504 comprises the data field of the orbit number (N) of media content.Data segment 508 comprises the data field of the distance of medium.It is data field under the extended identifier situation that data segment 512 comprises the indication media identifier, and comprises the track fingerprint of all tracks on the medium.Data segment 516 comprises the get on the right track data field of fingerprint number of indication medium, to help to carry out identifying.Under the present case that comprises the extended medium identifier of all track fingerprint on the medium, this data field can comprise any unique identifier that all track fingerprint of indication exist.Under the situation that does not break away from the embodiment of the invention, can rearrange the order of data segment.
Those skilled in the art will recognize that based on the consideration of the present invention's instruction, this is the indication of extended medium identifier in the data segment 512, are enough to indicate all tracks to exist.Equally, under the situation of extended medium identifier, data segment 516 comprises some redundant information.Yet the retention data section 516 in the present embodiment, with permission starting point index first fingerprint from media identifier consistent between expansion and the non-extended medium identifier in media identifier.In another embodiment, data segment 516 can be deleted fully, and the process of resolving and explain media identifier can be designed to first fingerprint in the extended medium identifier is positioned at the relative position of non-extended identifier track fingerprint number.In order to resolve media identifier, arbitrary configuration is all enough, and has considered many this distortion when writing.Other distortion may also meet specific embodiment.
Consider that the track fingerprint algorithm can develop at any time.Different algorithms can provide the different size track fingerprint that can be used as media identifier (such as media identifier 400 or media identifier a 500) part.Equally, according to carrying out the content that fingerprint is handled, fingerprint algorithm can be created the fingerprint of different size.In either case, the media identifier data segment of the track fingerprint data segment starting point that all can be revised as at fingerprint comprises length field.Comprise length field by starting point, resolve and explain that the process of media identifier can be designed to adapt to any fingerprint format and any length medium identifier in each finger print data section.
Therefore, meeting the computer data signal that specific embodiment of the present invention is embodied as bit stream has: the data segment of the data segment of content distance calculation on the data segment of content tracks number, the presentation medium on the presentation medium, track fingerprint indication that the expression bit stream comprises all tracks on the medium and a plurality of data segments of the track fingerprint of a track on the presentation medium respectively.
With reference now to Fig. 6,, one of medium content identification process may be shown as medium content identification process 600 by embodiment.The part of the medium identification method of discussing at the item 356 of Fig. 3 above medium content identification process 600 can form 300, and can go up execution at server or group of server (such as media identification 120 and meta data server 124), this server is coupled to the relevant data storehouse that comprises the identifying Useful Information.
Medium content identification process 600 starts from 604.608, identified server receives with media identifier 400 forms represents the track fingerprint from the media content of medium identification method 300, orbit number and ' distance ' on the medium.
612, server is attempted to find coupling in the media database that comprises ad-hoc location (for example, comprise as the identification track of first track on these medium all medium) identification track.If do not find fingerprint matching, then carry out range search 616 612.If in 616 unidentified distances, then 620 Unidentified content-message is sent to medium identification method 300, and process finishes 624.Yet,, create the media list that has with all medium of same distance identification 628 if carried out Distance Matching 616.Consider the different recording that may have same track on the different medium, can create media list, to help determining which medium is inquiry main bodys.Media list combines all medium that comprise as the identification track in the same position in the medium mid-game in the device.In many cases, media list may just comprise the medium that same position gets on the right track.
632, the institute in the orbit number in the media identifier and the media list might be mated compare, to determine whether to exist in media list each coupling of orbit number.If there is no, then forward 620 to, Unidentified content-message is sent to medium identification method 300, and process finishes 624 at this about the coupling of orbit number.Yet,, from tabulation, delete all items that do not match 636, and this may be new fingerprint and the indication that this content information can be added to database in 640 issues if in media list, there is orbit number coupling with any.May this thing happens: some media items in the media database may not have all tracks that fingerprint is handled in track database, therefore adds this information and will help gap in the padding data library information.
644, media information returns medium identification method 300.If a plurality of options of residue in media list, then the user can select suitable media identification, and the selection of user's affirmation is sent to track identification server process, so that based on media data storage track information.In the present embodiment, the duplicate customer clauses and subclauses of same orbit information based on medium can be used as the effective orbital data input relevant with track fingerprint, to eliminate user's error entries.Subsequently in 624 terminal procedures.
When having fingerprint matching, other possibility branch road of decision block 612 appears.In this case, forward 648 to, create media list once more with all possible coupling at this.652, whether the orbit number on the inquiry main body medium exists coupling.If in 652 couplings that do not have an orbit number, then 620 Unidentified content-message is sent to medium identification method 300, it can be sent to the user at this, and process finishes 624.Yet, if there is the coupling of orbit number, in 656 all media list entries that do not match of deletion.In this, media list will comprise at least one, but also can comprise multinomial.
660, the residual term in the media list can be compared with the main body medium that are used for range observation.For example (but being not limited to), if used distance be all tracks on the medium length and, then the distance of the media items in the database in the offset from body medium prescribed percentage can be thought enough similar (for example, mark or number percent).Equally, if this distance media items in database is specified in the absolute distance (for example several milliseconds), can think that then the main body medium are enough similar.But these examples only are exemplary starting points, and can think that in the present technique implication the reasonable measurement of " similar " can improve with experimental technique at any time.Can use and for example have that expert system, neural network and various other algorithm of adjusted value are determined effective similarity distance at any time.
