Embodiment

Illustrative methods disclosed herein, equipment, system and goods (article of manufacture) can be for measuring the exposure rate of Streaming Media.Some such illustrative methods, equipment and/or goods are measured this exposure rate based on media element data, user consensus data and/or media apparatus type.These examples disclosed herein can be for for example monitoring, such as individual, computer, flat computer (

), the transmission of the Streaming Media that receives of mancarried device, mobile phone, internet equipment and/or other customer set up place that can play the device of media.Additionally or alternatively, exemplary realizations more disclosed herein can be for monitoring the playback of the media of local storage in media apparatus.The media element data that exemplary monitoring process collection disclosed herein is associated with the media that present by media apparatus, and these metadata are associated with the user's of media apparatus demographic information.Like this, the media element data based on collecting generate detailed exposure rate measurement with associated user's demographics.

Use mobile device (for example, smart phone, flat computer, MP3 player etc.) to watch media increasing gradually in recent years.At first, the application (for example app) that service provider creates customization is to play its media.But along with the more eurypalynous mobile device with different software requirement, version and compatibility etc. comes into the market, service provider starts display stream medium in the browser of mobile device.Therefore, many users watch Streaming Media by the browser of their mobile device.In view of access medium by this way becomes more and more general, how understand user carries out alternately (for example, understand what media is presented, how media are presented etc.) and provides valuable information to service provider, advertiser, content supplier, manufacturer and/or other entity with Streaming Media.

Here in the example of explanation, from media provider (for example, such as satellite provider, cable television provider, tangible media provider (, the digital video disk of mailing (DVD) service etc.) receiving media.Media be provided as from service provider spread be passed to one or more at client terminal device to present at described client terminal device.In this example, media are provided as transport stream.In some instances, from transport stream, extract the measurement data with the first form.In some such examples, described transport stream is corresponding to moving images expert group (MPEG) 2 transport stream that send according to HTML (Hypertext Markup Language) (HTTP) live TV stream (HLS) agreement.Yet, this transport stream can be additionally or alternatively corresponding to any other form of past, present or future, for example, MPEG4, HTTP security protocol (HTTPS), file transfer protocol (FTP) (FTP), Secure File Transfer Protocol (SFTP) and/or send according to these forms.

Audio watermarking technique is for identifying the technology of media of the media content etc. of media content such as television broadcasting, radio broadcasting, download, streaming medium content, packing in advance.Existing audio watermarking technique is by for example, carrying out identification medium having enough the Audiocode (, watermark) embedding such as identification information in hiding other audio frequency of signal level of watermark and/or video component.As used herein, word " code " or " watermark " are used interchangeably, and be defined as representing can for identification medium or such as tuning (for example, group character header) other object and insert or be embedded into for example, identifier in the audio or video of media (, program or advertisement).

From based on comprising and/or to be embedded in the media surveillance technology of code in the media that are monitored and/or watermark different, the media surveillance technology based on fingerprint or signature conventionally generates media by one or more inherent characteristics of the media that are monitored and produces fully unique agency in Looking Out Time interval.Such agency is called as signature, and can adopt string number value, waveform etc. to represent the form such as the media signal of audio frequency and/or vision signal, forms the media that are being monitored and presents.Good signature is conventionally and can repeats now processing identical media, but be at other that process other media, is unique now.Therefore, word " fingerprint " and " signature " are used interchangeably, and are defined as representing the agency for identification medium from one or more inherent characteristic generation of media.

Media based on signature monitor and (are for example usually directed to determine, generate and/or collect) by the media signal of the media apparatus output being monitored (for example represent, audio signal and/or vision signal) signature represent and the signature being monitored and for example, one or more reference signature corresponding to known (, with reference to) media resource compared.Can assess various standards of comparison such as cross correlation value, Hamming distance to determine whether the signature being monitored mates with specific reference signature.When mating between the signature of having found to be monitored and one of them reference signature, can the serve as reasons specific reference medium source that represents with the reference signal of the signatures match being monitored of the media identification being monitored is corresponding.Because collected the attribute of identifier such as media, presentative time, broadcasting channel etc. for reference signature, these attributes and the media that are monitored (signature being monitored mate with reference signature be monitored media) can be associated after therefore.

In some instances, the metadata being embedded in media is the first form (for example, watermark, signature, code etc.).In some instances, the measurement data that has the first form comprises the audio frequency watermark in the audio-frequency unit that is embedded into media.Additionally or alternatively, the measurement data with the first form can comprise the video of the video section that is embedded into media (for example image) watermark.Many client terminal devices can not be used the metadata of the first form, and/or in some cases, do not have enough disposal abilities of the metadata of identification the first form.Like this, here, in the example of explanation, service provider identifies watermark, and is the second readable form of client terminal device by metadata conversion.The metadata of the second form can be corresponding to the metadata of for example text formatting, such as for being included in the text formatting of timing text track (the timed text track) file of transmission associated with Streaming Media.

Timing text track is and web page interlinkage, the document that sends and/or embed described webpage together with described webpage and/or file that media are shown.Timing text track for example defined, in the correspondence position being associated with media demonstration or the time of time showing text (, closed caption (closed captioning), captions, annotation, advertisement, metadata etc.).For example, timing text track can stipulate that phrase " this is to obtain Patent right invention " should present the 00:01:12 demonstration after starting at media, display unit (such as TV etc.) should utilize closed caption option., in the example of explanation, be here display media mark timing text track in webpage.The example web page of exemplary approach has been shown in Fig. 3, and in this exemplary approach, timing text track can be associated with media.In the example of explanation, require timing text track to be independent of the webpage of the meta-attribute of the timing text track label based in webpage.Like this, in the example of Fig. 3, timing text track is connected to webpage, but is not all incorporated in wherein.Yet in some instances, timing text track is included in webpage.

Timing text track document comprises and starts prompting, finish prompting and point out relevant data to these.Start prompting and finish the time that prompting has defined the event that triggering is associated with time text track in related media.In some instances, timing text track is for causing the captions that define in the data that are associated with described prompting and/or the demonstration of caption data.When arrival starts to point out, show captions and/or caption data.When arriving end prompting, from display, eliminate captions and/or caption data.Fig. 4 shows the timing text track file of example.

In some disclosed examples, Streaming Media is used HTTP live TV stream (HLS) to send to client terminal device via HTML version 5 (HTML5) webpage.Yet, can be additionally or alternatively use any other past, at present and/or media streaming is sent to the method for client terminal device, for example, HTTP safety (HTTPS) agreement.Additionally or alternatively, can be additionally or alternatively use in the past, now and/or any other homepages language in the future.HTML version 5 (HTML5) allow that meta-data pack is contained in timing text track and/or allow by metadata with such as Media Stream etc., associate.In some disclosed examples, client terminal device shows the media that receive via HLS with browser.Additionally or alternatively, in some disclosed examples, client terminal device is used media renderers (for example, browser plug-in, application, framework, application programming interfaces (API) etc.) to show the media that receive via HLS.

Here, in some examples of explanation, client terminal device is to service provider's requested webpage.Here in some examples of explanation, web page definition by by the independent timing text track document of request of client terminal device.In some instances, timing text track document is provided by service provider.Yet in other example, timing text track document is provided by other entity beyond service provider, for example, the hub facility of audience measurement entity etc.In some instances, timing text track document is comprised in webpage, makes not need additional request access timing text track document.

In the example of explanation, by the metadata of recovering to transmit, monitor media exposure rate metric in timing text track below.In some instances, via DOM Document Object Model (DOM) object, recover metadata.DOM is for showing the object of HTML (HTML) form interactional cross-platform and do not rely on the instrument of language with these objects.Yet, can be additionally or alternatively use in the past, at present and/or any other form in the future, language, agreement etc., for example HTML5.DOM provides the internal representation of the webpage presenting.Via the access of Javascript for example DOM, make it possible to the object that access defines within comprising the webpage of timing text track for example.

Although can be additionally or alternatively use in the past, now and/or other metadata format of in the future any, in some instances, metadata be stored in timing text track with ID3 tag format.In some instances, for example the media renderer of QuickTime player (for example, media plug-in unit) is sent DOM event, and the prompting for example being triggered by the prompting defining in timing text track changes event.Here, in the example of explanation, DOM event is caught via JavaScript.Yet, can be additionally or alternatively use in the past, now and/or any other script in the future, language, instruction set etc.By catching DOM event, can extract via DOM the metadata (for example, ID3 label data) of timing text rail event.Once extract metadata, metadata for example can combine and send to hub facility to analyze and/or to pool together with the data of collecting from other device with the out of Memory such as with the associated cookie data of device, timestamp etc.

Exemplary " addeventlistener " function 320 being included in the HTML code 300 of Fig. 3 has been realized the event sniffer 220 in Fig. 2.In this example, for example, by (stipulating predetermined element, be identified as having the component identifier of id ' track '), regulation event type (for example, " cuechange " etc.) and regulation should carry out " TrackChangeFunction " function and carry out load events monitor 220 when event being detected.In this example, the event type detecting is " cuechange ", and " cuechange " is the event being triggered by media renderer 210.Yet, additionally or alternatively, also can use the event of any other type, for example, the event type associated from different media renderers, with the associated event type of the different triggerings of media renderer 210, with the event type of the program association that (" QT ") is different etc.

The illustrative instructions group function 330 being included in the exemplary HTML code 300 of Fig. 3 recovers the metadata being associated with the html object of triggering " TrackChangeFunction () ".In this example, when by media renderer 210 displaying video label 310, will carry out trigger event according to the event defining in the timing text track file by text track road instruction 315 signs.In " track " object of indicating in this example,, recover metadata from the getElementById function in instruction 320.In this example, for example, by the metadata store (, high-speed cache, buffering etc.) of recovering in local variable " myCues ".

In this example, the metadata of recovery is ID3 form.Yet in some instances, the metadata of recovery can be in the past, now and/or other form of in the future any, for example Java Script Object Notation (JSON).In some instances, metadata is stored as cryptographic Hash.In some instances, the HTML code 300 of Fig. 3 also comprises for take the function that the metadata conversion of the first form storage is the second form.

In this example, the square frame 350 in the exemplary HTML coding 300 of Fig. 3 sends to text filed 351 (being defined as " demonstration " in example) by the metadata after conversion.In some instances, frame 350 is modified to additionally or alternatively the metadata after conversion is sent to hub facility 170.In some instances, metadata sends (frame 350) with ID3 form.Additionally or alternatively, in some instances, except metadata or as the substituting of metadata, frame 350 sends other information, for example, user totem information, client-side information, timestamp, identifier etc.

Fig. 4 is exemplified with exemplary timing text railway code 400, and timing text railway code 400 represents the exemplary timing text track that can be used by the exemplary media monitor of Fig. 2.In described example, timing text code 400 is WebVTT forms, as indicated in format identifier 415.Yet timing text code 400 can be in the past, now and/or other form of in the future any, such as timing text markup language (TTML) form etc.The timing text code 400 of Fig. 4 comprises the first timed events 410.The first timed events 410 comprises time started 411 and end time 412.The first timed events 410 comprises the metadata 420 formaing according to ID3 form.Particularly, metadata 420 comprises contentid part, and contentid partly comprises identification information 425.In this example, the media that identification information 425 signs are presenting via associated Media Stream.

Fig. 4 is exemplified with the development of the time of associated media.For example, Fig. 4 shows time A450, time B460, time C470 and time D 480.In this example, in the first period after time A450 and before time B460, play the first fragment of TV programme.In the second period after time B460 and before time C470, broadcast advertisement.In the 3rd period after time C470 and before time D 480, play the second fragment of TV programme.

Timing text railway code 400 is described and is changed event by presenting associated the prompting triggering with media.In this example, by first 410 the first periods of sign of timed events.The first fragment of the identification information 425 sign TV programme of the metadata 420 of the first timed events 410.In this example, the first timed events 410 is triggered after played one second at media.It is because in some instances that the first timed events 410 is triggered after played one second at media, load events monitor function 320 not yet in played first second of media.In some instances, use the time started of alternative, for example zero second (for example, not postponing), five seconds, ten seconds, one minute etc.

In this example, the second period is by the second timed events 440 definition.The second timed events 440 starts for one second after the first period completed.Yet, can be additionally or alternatively use any time delay At All Other Times.The second timed events 440 comprises the metadata that is identified at the advertisement of playing in the second period.

In this example, the 3rd period is by the 3rd timed events 445 definition.The 3rd timed events 445 starts for one second after the second timed events 440 completes.Yet, can be additionally or alternatively use any time delay At All Other Times.The 3rd timed events 445 comprises the metadata of the second fragment that identifies TV programme.In this example, the metadata of the second fragment of sign TV programme is different from the metadata of the first fragment that identifies TV programme.Yet in some instances, the metadata of the second fragment of sign TV programme is identical with the metadata of the first fragment of sign TV programme.

In this example, prompting change event is triggered in the beginning of for example, each event in timed events (, the first timed events 410, the second timed events 440, the 3rd timed events 445 etc.).Like this, when media, by timing text track, defined when being presented in (comprising the beginning that media present) different period before media, timed events 410,440,445 occurs.In this example, the timing text track period is divided into the fragment corresponding with the media that are presented (for example, the first timed events is associated with the first fragment of TV programme, and the second timed events 440 is associated with advertisement etc.) with corresponding timed events.

In some instances, timing text rail event is divided into the fragment (for example, five seconds, ten seconds, a minute etc.) of regular length, and is associated with the media that present in the fragment of each regular length.Timing text track is divided into a plurality of fragments and is conducive to be convenient to accurately gather media monitor data, this is due to the more data point that has gathered the different time during presentation medium presents.When using together with timestamp, (for example use small fragment, 30 seconds, one minute etc.) be conducive to detect such as skipping, stop, other media alternative events of time-out, broadcast event, this is because the expected duration between the prompting of timing text track can being changed compare with the actual duration between timing text track prompting change.In some instances, timing text track is not divided into discrete fragment, but comprises the individual chip that the whole media of covering present.

In Fig. 5 and/or Fig. 6, illustrated the service provider 120 that realizes in Fig. 1 and/or the media monitor 165 in Fig. 1 and/or Fig. 2 example machine readable represent flow chart.In these examples, machine readable instructions comprises by the program of carrying out such as the logical circuit that contacts the processor 812 shown in the exemplary process applicator platform 800 that Fig. 8 discusses below.Program can be included in and such as computer-readable medium (for example be stored in, CD-ROM, floppy disk, hard disk drive, digital versatile disc (DVD), Blu-ray disc or the memory associated with processor 812) the software of tangible computer-readable medium in, but the part of whole program and/or program can alternatively be carried out by the device beyond processor 812, and/or is included in firmware or specialized hardware.In addition, although with reference to illustrative flow chart description in Fig. 5 and/or Fig. 6 example procedure, can alternatively use the exemplary services provider 120 that realizes in Fig. 1 and/or a lot of other methods of the exemplary media monitor 165 in Fig. 1 and/or Fig. 2.For example, the execution order of square frame can be changed, and/or the square frame of some descriptions can be changed, delete or combine.

As described in the text, the instruction that exemplary process in Fig. 5 and/or Fig. 6 can be used coding (for example, computer-readable instruction) realize, these instructions such as computer-readable medium (are for example stored in, hard disk drive, flash memory, read-only memory (ROM), CD (CD), digital versatile disc (DVD), high-speed cache, random access memory (RAM)) in tangible computer-readable medium and/or other storage medium, in these media, the time that information can be stored random length (for example, can store for a long time, interim storage, short time storage, adhoc buffer and/or described information is carried out to high-speed cache).As used in this article, term " tangible computer-readable medium " can clearly be defined as the signal that comprises any type computer readable storage medium storing program for executing but do not comprise propagation.Additionally or alternatively, the instruction that exemplary process in Fig. 5 and/or Fig. 6 can be used coding (for example, computer-readable instruction) realize, these instructions are stored in non-instantaneous computer-readable medium, such as hard disk drive, flash memory, read-only memory, CD, Digital video disc, high-speed cache, random access memory and/or other storage medium, in these media, the time that information can be stored random length (for example, can store for a long time, interim storage, short time storage, adhoc buffer and/or described information is carried out to high-speed cache).As used in this article, term " non-instantaneous computer-readable medium " can clearly be defined as the computer-readable memory that comprises any type but the signal that does not comprise propagation.As used in this article, while being used as transition word (transition term) in the preamble of phrase " at least " in claim, its scope is open, as term " comprise " represented implication also open.Therefore, in preamble, use the claim of transition word " at least " can comprise except clear and enumerate the element those elements in the claims.

Fig. 5 is the flow chart of example machine readable 500 that can carry out to realize the exemplary services provider 120 of Fig. 1.The media that the execution of the example machine readable 500 of Fig. 5 receives media provider 110 from service provider 120 media identification device 125 (frame 510).In this example, for example, in broadcast (on-the-spot broadcasting), receive described media.Yet media store and/or be cached in media identification device 125 in some instances.

Media identification device 125 in this example is then identified media (frame 520).Media identification device 125 for example, is identified media by extract measurement data (, signature, watermark, code etc.) from media.Measurement data based on extracting, media identification device 125 generator data (frame 530).In example, metadata generates with ID3 form.But, can be additionally or alternatively use any other metadata format.In addition,, in example, the measurement data of metadata based on extracting generates.Yet in some instances, metadata can be by being used some measurement data that extract or all measurement data inquiry external sources extracting to generate.

Then, transcoder 130 transcodings (frame 540) of the serviced provider 120 of media.In example, media are transcoded into can be via the MPEG2 transport stream of HTTP live TV stream (HLS) transmission.Particularly, service provider 120 metadata embedded device 135 is embedded into metadata (frame 550) in the timing text track being associated with HLS stream.In this example, metadata is embedded in HLS and flows in outside timing text track.Yet in some instances, metadata is embedded in media itself as for example closed caption.For example, timing text orbit information can be coded in MPEG2 transport stream as triggering according to the mode identical with external definition text track the closed caption data of timed events.In this example, the metadata being embedded in timing text track is identified at the different media that different time is presented.

Then, the medium dispenser 140 of the serviced provider 120 of media sends (frame 560).In example, media are utilized HTTP live TV stream (HLS) and send.But, can additionally or alternatively with any other form and/or agreement, send (for example, broadcast, clean culture, multicast etc.) media.

Fig. 6 mean can be performed to realize Fig. 1 and/flow chart of the example machine readable 600 of exemplary media monitor 165 in Fig. 2.The realization of the example machine readable 600 of Fig. 6 for example, starts from the instantiation (, being loaded by client terminal device 160) of media monitor 165.Then, the media renderer 210 of media monitor 165 starts to present media (frame 610) by the demonstration object for example loading for presenting via client terminal device 160.In example, show liking

object.Yet, can be additionally or alternatively use the demonstration object of any other type.When presenting media, media renderer 210 is recovered the timing text track file of relevant to media (for example, being associated with the object showing) of sign.

The event sniffer 220 of media monitor 165 starts event to monitor (frame 620).In this example, event sniffer 220 is monitored the JavaScript event being triggered by media renderer 210.In this example, JavaScript event is timing text track prompting change event.Yet in some instances, event sniffer 220 is monitored any other event, for example, for example, for example, such as media change event, user interactions event (, when user clicks an object), presented event (, the page loads) etc.If event sniffer 220 does not detect event, event sniffer 220 continues event to monitor, until media monitor 165 is closed.Different from captions and/or advertisement display system, the media monitor 165 in this example does not show information when timing text track prompting change event being detected.For example, captions and/or ad system can show captions and/or advertisement to user based on timing text track prompting change event and/or based on whether enabled captions and/or advertisement in media watch-dog 165 during media show.On the contrary, no matter whether in media watch-dog 165, enable captions and/or advertisement, to user, do not shown the data that are associated with timing text track prompting change event.

If event sniffer 220 detects event, the metadata restorer 230 of media monitor 165 recovers metadata (frame 630) from representing the DOM object of timing text track.Particularly, in example, event sniffer 220 passes to metadata restorer 230 by event object.Metadata restorer 230 checks that this event object is to recover metadata.For example, yet in some instances, event sniffer 220 transmits the identifier of object (, the demonstration object of media renderer 210), this identifier indication metadata restorer 230 will recover the object of metadata.In example, the form of metadata is ID3 label.Yet, additionally or alternatively, metadata can be used any other form.

Then the form (frame 640) that the transmitter 250 that, the metadata conversion device 240 of media monitor 165 is media monitor 165 by metadata conversion uses.In example, metadata is converted to text formatting from binary data format.In some instances, metadata is resolved to identify the part (for example, field, section etc.) of for example, concern in metadata (, school, artist, song title, album name, dispatching station/server site etc.).In some instances, metadata conversion device 240 is embedded into the identifier that presents the identifier of device and/or present the user of device in metadata.The identifier that presents the user of device and/or present device is included hub facility 170 can be associated the media that are presented with the user who presents device and/or present device.In example, metadata conversion device 240 before metadata is sent to hub facility 170 in metadata joining day stamp.Add timestamp (for example, the time that recording events occurs) and make it possible to identify exactly the time that the media that are presented and/or this media present, and/or the time that the media that are presented and/or this media present is associated with the user who presents device.

In some instances, metadata before being sent by transmitter for example, without conversion (, metadata sends with the form being recovered by metadata restorer 230).In such example, hub facility 170 such as by by metadata conversion, be different form, the analytical element data concern part in identification metadata etc. by metadata conversion centered by the form that uses of facility.The identifier that object that presented media are presented with identification medium is convenient in the conversion of 170 pairs of metadata of hub facility is associated.In some instances, hub facility 170 is stamped timestamp by metadata when receiving metadata.Add timestamp and make it possible to identify exactly the time that the media that are presented and/or this media present, and/or the time that the media that are presented and/or this media present is associated with the user who presents device.

Then, transmitter 250 sends to hub facility 170 (frame 650) by metadata.In example, adopt HTTPPost request to send metadata.Yet, additionally or alternatively, can use any other method that sends data and/or metadata.For example, can use file transfer protocol (FTP) (FTP), HTTP Get request, asynchronous JavaScript and extend markup language (XML) (AJAX) etc. to send metadata.In some instances, metadata is not sent to hub facility 170.The demonstration object that for example metadata can send to client terminal device 160 is to show to user.In example, by real time, (for example, the form to flow) sends to hub facility 170 to metadata.For example, yet in some instances, before being sent to hub facility 170, metadata can be stored (, high-speed cache or buffering etc.) a period of time.

Fig. 7 is the block diagram of the exemplary realization of the exemplary HLS stream 700 that shows of exemplary media monitor that can be in Fig. 2.In the example of Fig. 7, HLS stream 700 comprises inventory 710 and three transport stream.Yet, can be additionally or alternatively use the transport stream of any other quantity and/or type.In example, the exemplary HTML instruction 300 of Fig. 3 comprises the instruction of Additional Cargo List 710.In example, the exemplary HTML instruction 300 of Fig. 3 comprises the instruction of the timing text track 400 that loads Fig. 4.In example, inventory 710 is to client terminal device, to describe the .m3u8 file of available transport stream.Yet, can be additionally or alternatively use in the past, now and/or any other file format in the future.In some instances, can omit inventory 710, and media monitor 165 can directly use transport stream.In example, client terminal device for example, recovers inventory 710 in response to showing the instruction of HLS element (, video elementary).For example, the frame in Fig. 3 310 comprises that client terminal device should present the instruction that is stored in the HLS element being identified by inventory 710 that " movie.mp4 " locate.

HLS is a kind of self adaptation form, that is to say, although a lot of device has recovered identical inventory 710, according to one or more factor, can show different transport stream.For example, (for example there are different available bandwidths, high-speed Internet connection, low speed the Internet connection etc.) and/or the device of different display capabilities (for example, such as cellular small-size screen, such as the medium size screen of flat board and/or notebook, such as the large scale screen of TV etc.) can select to be applicable to the transport stream of its demonstration and/or bandwidth ability.In some instances, the cell phone that has the small screen and a limited bandwidth is used the transport stream of low resolution.Alternatively, in some instances, there is the television set that large-screen is connected with high-speed Internet and use high-resolution transport stream.For example, when the performance change of device (, this device connects while transforming to low speed the Internet connection from high-speed Internet), this device can be switched to different transport stream.

In the example of Fig. 7, show high-resolution transport stream 720, intermediate resolution transport stream 730 and low resolution transport stream 740.In this example, each transport stream 720,730 and/or 740 is representing a part (for example, 5 seconds, 10 seconds, 30 seconds, 1 minute etc.) for related media.Correspondingly, high-resolution transport stream 720 is corresponding to the first of media, and the second high-resolution transport stream 721 is corresponding to the second portion of media, and third high resolution transport stream 722 is corresponding to the third part of media.In addition, intermediate resolution transport stream 730 is corresponding to the first of media, and the second intermediate resolution transport stream 731 is corresponding to the second portion of media, and the 3rd intermediate resolution transport stream 732 is corresponding to the third part of media.In addition, low resolution transport stream 740 is corresponding to the first of media, and the second low resolution transport stream 741 is corresponding to the second portion of media, and the 3rd low resolution transport stream 742 is corresponding to the third part of media.Although show three transport stream for every kind of resolution in the example of Fig. 7, additionally or alternatively, can use an any amount transport stream of an any amount corresponding part that represents media.

In example, each transport stream 720,721,722,730,731,732,740,741 and/or 742 comprises video flowing 750,751,752, audio stream 755,757,752 and metadata streams 760,761,762.According to the resolution of the transport stream associated with video flowing, video flowing 750,751 and/or 752 comprises the video associated with the media of different resolution.Audio stream 755,756 and/or 757 comprises the audio frequency relevant to media.Metadata streams 760,761 and/or 762 comprises metadata, such as timing text orbital data, to link, closed caption data and/or the ID3 label associated with media of timing text orbital data.In some instances, owing to may sending to media monitor 165 as timing text track 400 for measuring the information of Streaming Media exposure rate, therefore can not comprise metadata streams 760,761 and/or 762.In some instances, metadata streams 760,761 and/or 762 comprises the information (for example, closed caption information etc.) not being included in timing text track 400.
