To combine accompanying drawing below, embodiments of the invention will be described.
As shown in Figure 1, the system of the method that is applicable to the network customization play content of an embodiment of the present invention comprises: a plurality of content source 10, the play content of storing audio, video format and related data; Single-sign-on interface 20; For the user provides unified single-sign-on services; Make the user can be through a plurality of content source 10 of single interface accessing, thus the problem of the frequent login of needs when avoiding the customization playlist and visiting the resource of a plurality of content source according to playlist play content needs; Background application unit 30; The request of response user through browser (user interface) obtained the content correlated information data from content source 10, filters, analysis etc.; And result fed back to browser, and provide the language independent interface to supply browser to call to external browser; Browser cell 40 provides the browser that presents operation interface and operating result (for example: content playlist, contents view show that ratio is amplified and dwindled time shaft view etc.) demonstration for the user.Through this system; Solved conventional content customizing system and can not polytype contents such as net cast, live audio, video request program, Audio on Demand be added on the problem in the single content play timetable (content playlist), can realize that sound, video content add, edit, delete, duplicate, preview, amplify, dwindle, function such as image is played up.
The play content that stores in each content source 10 comprises the data flow (such as net cast content, live audio content, video on demand content or Audio on Demand content etc.) of one type of play content, and content playlist information, user interface information, relevance information, user's Information on Collection etc.As shown in Figure 1, content information database 101 in the content source 10, live audio content source 102, net cast content source 103, Audio on Demand content source 104 and video on demand content source 105 also comprise customization play content database 106.
Content information database 101 has stored the information of all kinds of play content among the content source 102-105.What store in live audio content source 102 and the net cast content source 103 is the address of the Http data flow of live content.Stored the content playlist (back literary composition will specify) of customization in the customization play content database 106.The on-demand content of audio frequency and video is stored in respectively in the above-mentioned content source 104,105 with the form of routine.For example, the data format of audio content can adopt RealAudio, MP3, WMA, APE, FLAC and AAC etc.The data format of video content can adopt AVI, nAVI, DV-AVI, MPEG, DivX, MOV, ASF, WMV, RMVB etc.In embodiments of the present invention, behind the storage source file, convert the audio content unification into MP3 format, video content is stored after converting the FLV form into.Will be among the present invention with the form that is unified into URL to the visit of live content with to the data access of on-demand content.
Live type content is provided with the attribute that begins to play with time of finishes, though program request class content does not begin to play the time with finishes, is provided with the playing duration attribute.The broadcast time started of program request class content can be set up on their own by the user.The user can set the live content of oneself wanting to listen to/watch and play the beginning and ending time between the time of the broadcast start time of live content and finishes.All kinds of play content are formed content playlist by the tactic data combination that begins broadcast time.
Usually, when the user carries out various data maintenances (for example create and revise content playlist, visit the content playlist of other people collection etc.) in the contents reproduction system that oneself customizes, need a plurality of content source of login carry out data access.
Single-sign-on be meant content source of login be addressable all have the other guide source of same subscriber collection, when visit other guide source, need not the secondary login.According to one embodiment of the present invention, set up single-sign-on interface unit (SSO) 20, be used to verify user login information and safeguard logging status.This checking can adopt the mode of conventional " user name+password " to carry out.Certain belongs to the content of content source A and first during sign-on access content source A, whether the access control unit judges of content source A is logging status when user inquiring, if not, then browser is redirected to SSO 20.The user submits username and password at SSO 20 to through the login page of browser display; SSO 20 verifies; Checking through after user's logging status is write among the Cookie, and (bill is a character string through encrypting to produce a Ticket; Like GT-1984-vmbWkAdvfIeIKWfS5YHHNu31jpdBCZTZVForbc), the browser that will present to the user simultaneously is redirected to content source A.Promptly when the browser access server, server returns 302 conditional codes and the target URL (URL) that is redirected.After browser is discerned 302 conditional codes, initiate another request, accomplish and be redirected according to redirection target URL.This moment, the access control unit of content source A extracted this Ticket, initiated the http request to SSO 20, and whether Ticket is effective in checking, if effectively then confirm that user identity is a logging status.
Equally, when user capture content source B, content source B is redirected to SSO 20 with browser, and whether the Cookie of SSO 20 checking user logging status is effective, if effectively, produce another Ticket, and browser is redirected to content source B.The access control unit of content source B extracts this Ticket, initiates the http request to SSO 20, and the validity of checking Ticket is accomplished the checking to user identity.For realizing aforesaid operations, each content source obtains need identity information be stored in (as: among the session) the current content source behind the user identity from SSO 20, in order to using at any time.
Background application unit 30 adopts Java language to realize.Can realize a plurality of application systems through this unit.Content playlist system for example, the content playlist of stored audio and video.Each content all has specific attribute in these content playlists, for example:
Play attribute: live video, live audio frequency, order video, program request audio frequency;
Categorical attribute: music, amusement, news, health, opera, tourism, cuisines etc.;
Content source attribute: like XX Music Radio, XX education platform, XX traffic platform, XX sports station etc.;
Period attribute: the i.e. time started of play content and concluding time;
Name attribute: the i.e. title of play content.
Background application unit 30 can provide the back-office support to all kinds of content choice.Alternative condition to content can comprise each above-mentioned generic attribute.In addition, the text input frame can also be set, receive the user and select according to the literal of own interested content (title that comprises above-mentioned various attributes) input.For example the user selects Audio on Demand, and background application unit 30 just can provide the audio file that goes out by Audio on Demand condition query tabulation.If the user selects live audio, background application unit 30 just can provide the audio file that goes out by live audio condition query tabulation.
After the user selects these attributes or manually imports interested content name or attribute; The data access unit 301 response browse request of background application unit 30; Querying condition according to user's input is organized the SQL query statement; From content data base, read corresponding data, and these data are carried out necessary encapsulation about play content information.Encapsulation to the play content information data comprises deletion and the conversion of initial data being carried out necessity.For example, for the unification of the data format that keeps dissimilar contents, convert the playing duration of on-demand content into time started and reproduction time, with unified with live content.For this reason, delete the playing duration of this on-demand content, duration converted to the time started and the concluding time (time started is defaulted as 00:00, and the concluding time is the time after the time started adding the content duration) of broadcast.
Background application unit 30 supplies browser to call through language independent interface (for example conventional JSON data-interface) is provided.Below be the code segment example of JSON data-interface:

Figure BDA0000158185150000061
Figure BDA0000158185150000071
Background application unit 30 can comprise a plurality of unit to support the user according to the selection of various conditions to content.For example:
Collection data cell 302: the content of other user's collections of user inquiring and the function of contents list data are supported to provide in unit 302.When the user selects the condition of " other user's collections "; Collection data cell 302 selects to inquire the content information data of other user's collection according to the user; And compare with the data of collection in the content data base, delete invalid content information data (like the Audio on Demand data of having been deleted).The content information data about this collection that then inquiry is obtained offers browser, to present to the user.
Relevance property analytic unit 303: when the user selected a content name to operate to add in browser, browser can be initiated the operation that Ajax asks to respond this user synchronously.For example:
Figure BDA0000158185150000072
The data of 303 pairs of content informations of relevance property analytic unit are analyzed, and find out classifying content attribute (music, physical culture, traffic with this content information ... Deng) or the information (title) of the identical content resource of other attribute return to browser.
Playlist filter element 304: when selecting in a plurality of play content tabulations that the user is listing; Unit 304 filters, analyzes these play content tabulations; For example deletion does not have the sky tabulation of play content etc.; The information of the effective content playlist that will stay after will filtering then is sent to browser, to present to the user.
Information filtering unit 305: the audio-video frequency content to being inquired according to the user inquiring condition filters, and deletes invalid content (as done the playing back content of delete flag by back-stage management person).
Browser cell 40 is supported for the user browser of operation interface with the content customization result that displays the play to be provided.Accomplish audio-video frequency content interpolation, editor, delete, duplicate, preview, amplify, dwindle, function such as image is played up, this unit adopts JavaScript, CSS (cascade CSS), HTML to realize.
Browser cell 40 comprises:
Classifying content unit 401 belongs to live type of still program request class according to this content of determined property of adding content, and encapsulated content data again, supplies time shaft to use.
Playlist maintenance unit 402 utilizes the conventional means of browser, the content playlist data is played up, and be plotted on the time shaft.Comprise that drafting and text to content time frame, current content masking-out layer, dynamic reminding frame, content time span axle blocks, time shaft amplifies, dwindle etc.
Particularly; Through (the Document Object Model: node and CSS (Cascading Style Sheets: CSS) DOM Document Object Model) of DOM in the routine techniques operating browser of Javascript; Can revise the layout and the pattern of browser display content, even content itself.Can accomplish work such as on the page, adding masking-out layer, ejection prompting frame, convergent-divergent time shaft thus.For example, for the convergent-divergent time shaft, the essence of convergent-divergent is exactly to revise width and the height that contents view shows.Through calculating original width of contents view and height, and on this basis with width with highly multiply by a scaling (as 3 times), calculate the width and highly behind the convergent-divergent, revise the CSS attribute of DOM node then.Browser can be played up DOM node (promptly drawing the display frame of content) by new CSS attribute after finding that the CSS attribute changes automatically, thereby realizes the convergent-divergent of time shaft.
View rendering unit 403: according to the content-data in the current content playlist model, calculate the coordinate position and the width of contents view, the CSS pattern of contents view is set.The demonstration of the contents view on the browser renders time shaft, and draw the time shaft scale, content masking-out layer and various mouse-over effect (like mouse-over on contents view time eject interface information prompting).
Action listener response unit 404: be responsible for to detect the user on time shaft and the DOM incident that produces of neighboring area, and transfer to the correlation function response according to the event type difference.Comprise incidents such as monitoring, response mouse move, click.Among the present invention, outside the conventional acquiescence monitoring of browser is handled, increased specific processing function, accomplished processing logic different event.
The special event that is realized comprises:
Drag contents view left frame incident, monitoring in the default event of browser has increased specific processing function, adjusts the position of the left frame of contents view, the beginning broadcast time and the time span line of content through this processing function.
Drag contents view left frame incident, monitoring in the default event of browser has increased specific processing function, adjusts the position of the left frame of contents view, the beginning broadcast time and the time span line of content through this processing function.
A processing examples of functions is following:
Figure BDA0000158185150000091
In the above-mentioned function, at first use statement " ctx.curItem.isLive () " to judge whether play content is live type.
If live type of content; Then add mouse and press (mousedown.drag) for page documents, mouse moves (mousemove.drag) and discharges (mouseup.drag) three event sniffers with mouse, these three event sniffers will be used for the incident that produces when process user is adjusted broadcast time of content.
If program request class content then ejects the adjustment content dialog box of broadcast time, the user can adjust the actual broadcast time of content through this dialog box.
Need explanation, have a lot of incidents all to belong to mouse click event, just the different corresponding processing logics of click location are different.This type click event all is to adopt conventional processing means.For example: click the incident of play content, cause the operation that produces the masking-out layer for this contents view, on browser, show as the contents view frame and become redness, and show delete button.
Playlist output unit 405, the encapsulated content playlist data according to the data of encapsulation, generates the customized content playlist of arranging by the time started sequencing, supplies user's preview.Can realize the live preview of customized content playlist thus, single/preserved in many days etc.And the user can carry out deletion action to the content of customization in preview interface.The content playlist of customization is stored in the customization play content database 106.A kind of backstage form of content playlist is following:
The content playlist example
Figure BDA0000158185150000101
In one embodiment of the invention, also comprise unified webpage player 50.The user can play the content in the content playlist that customizes after logining through the single-sign-on interface unit in this webpage player.The webpage player flows the suffix of URL and content data file through the broadcast of judging content; Confirm the data type (suffix like MP3 is the Audio on Demand content) of content, call the corresponding audio or video player plug-in broadcast content (data flow of different-format needs different player plug-in) that is installed on the webpage player interface through Javascript then.For this reason, the webpage player uses the JavaScript technology, from customized content played data storehouse 106, obtains content playlist information, and according to the broadcast time and the content-form of each content in the content playlist, selects to switch sound, video player broadcast content.
In order to guarantee that the webpage player can discern the dissimilar content playlist data in the content playlist, need set up unified content information form for content-data.This is set up unified content information form and mainly comprises: have the time started and the concluding time of broadcast in live type, and program request class content has only playing duration, therefore this two category information is unified into broadcast time and concluding time.
The method of the realization customization network play content of an embodiment of the present invention is described with reference to Fig. 2 and Fig. 3 below.
Step S001: after the user logins with username and password through single-sign-on interface unit (SSO) 20, according to each Class Options or the literal input frame that browser is listed, the input alternative condition.The data access unit 301 of unit, backstage 30 inquires sound, video content relevant in the content source 10 according to this alternative condition.After the access control unit of content source confirms that the user is logging status, allow data access unit 301 to inquire about and obtain content information, on browser, show the information of these sounds, video content.Be selected content pairing " interpolation " button in user's click browser, then this content is positioned on the time shaft.
In this step; Content search can be supported in the data search of polytype playing resource such as live audio, Audio on Demand, net cast, video request program, and can use restrictive conditions such as playing attribute, categorical attribute, content source attribute, period attribute, name attribute that Search Results is limited so that precise search.
Can default setting select to supply in the inventory user's selection in browser, all Play Systems, all classification, all the elements sources (resource), content name all periods under all being presented at.
For example, when the user has selected music assorting, then data access unit 301 make browser list item by item under that all playing resource provide, each available resources database, all periods, have a content name of all these music assorting attributes.When the user selects content name wherein, then the play content title of database storage is searched for according to this content name, find corresponding content resource.
For example; By content name query contents from database; The field (like name) that has a content name in the database in the table of content information stored, can then inquire about with the use SQL statement: select*from program where name like ' % content name A% ' searches for.
If the user is sound, a video content of selecting other user's collection; Then the collection data (content data item that promptly comprises play content title, attribute, time period, affiliated platform, classification etc.) of this collection sound, video content are confirmed to represent in data access unit 301 according to user's selection; Collection data cell 302 is analyzed and should be collected data; Comprise content designator, playing duration, content name etc., remove invalid data, as be labeled as the content of deletion by back-stage management person.
If will select the play content tabulation of other customization; 304 pairs of databases of playlist filter element are searched for; All the elements tabulation to searching is filtered; Delete invalid contents list and play content information, as by deletion or the customization contents list and the play content information of closing.
After the querying condition according to user's input inquired the title of sound, video content, 205 pairs of content name that inquire of audio frequency and video filter element were filtered, and the deletion invalid content is as breaking or expired content.Content information data with remainder is sent to browser then.
After the user chose the content that will add, browser sent request through Ajax to unit, backstage 30.
The code segment example of this request is following:
Figure BDA0000158185150000121
Relevance property analytic unit 303 response request, analyze and inquiry with the other guide of the relevant property of content that will add, send browser to, present to user's selection.
For example, this relevance determines according to type attribute.After the user has selected to have certain content of music assorting attribute, then inquire the content that all have this music assorting attribute,, audio frequency and video filter element 305 sends browser to after filtering, and present to the user and select.
Step S002: after the user selected to add the content on the time shaft to, classifying content unit 401 promptly belonged to live type of still program request class according to the broadcast type of this content of determined property of adding content, and encapsulated content data again, supplied time shaft to use.Because what on time shaft, use is uniform data format; And each content source has the data format of oneself; So need the encapsulation conversion, delete unwanted data or become other data to some transformation of data, as becoming start and end time to the duration transformation of data.
For example, for playing the content that type is live class, the data format before the encapsulation comprises: station information, host's information, broadcast scheduled flag symbol, content designator etc., Start Date and time (containing date and time), Close Date and time etc.Again after the encapsulation, data format comprises: content designator, time started (only containing free), concluding time (only containing free).
Step S003: through reading the broadcast time of live content, content is added in the content playlist model, content playlist is a data list of arranging in order by the content time started.By the play start time of playlist maintenance unit 402, search the position of this content in the content playlist of customization through the conventional lookup method such as dichotomy according to the interpolation content.
At step S004, eject the selection of time dialog box, carry out the linearity traversal through 402 pairs of current content playlist data models of playlist maintenance unit, calculate the vacant time period.Concrete mode is, according to the play start time and the concluding time of each content, for two adjacent content A, the B of in chronological sequence ordering, time started of B deducted concluding time of A, is exactly the vacant time between A, B.All the other by that analogy.The time started of the content the earliest in content playlist is exactly first the vacant time period in this content playlist, and the concluding time of the last content in content playlist is exactly the last vacant time period in this content playlist.
The time period of selecting to add to by the user or self-defined broadcast time section.After the user confirms reproduction time, by playlist maintenance unit 402 according to the content play time started, through the position of this content of binary search in content playlist.
At step S005, after the content-data that the user is selected added the content playlist data model to, playlist maintenance unit 402 adopted linear traversal method, calculated content broadcast time whether to have conflict.Computing formula is following:
If existing content A, C in the content playlist increase continuous the arrangement with the time started, newly adding content-data is B.The beginning of each content, concluding time are designated as st, et respectively, st<et and A.st<A.et≤C.st wherein, A.st≤B.st≤C.st.Conflict situations comprises:
1, identical: with A, B is example, and during and if only if A.st=B.st and A.et=B.et, it is identical to confirm as A, B broadcast time; B, the similar calculating of C situation.
2, all standing: with A, B is example, during and if only if A.st=B.st and B.et>A.et, then confirms the broadcast time that broadcast time of B covers A fully; B, the similar calculating of C situation.
3, preceding covering: during and if only if C.st<B.et<C.et, judge that the broadcast time of B covers the first half of C.
4, the back covers: during and if only if A.st<B.st<A.et≤B.et, judge that the broadcast time of B covers the latter half of A.
5, do not have conflict: with A, B is example, during and if only if A.et≤B.st, judges that A, B broadcast time do not have conflict.B, the similar calculating of C situation.
At step S006, when there is conflict in existing content in the content that will add and the content playlist, then point out the user whether to cover existing content.If the user selects not cover then cancels the content of being added, flow process stops; If the user selects to cover existing content then forwards step S007 to.
If the content part that the user selects has covered meaningful in the content playlist, the time started of the content that is then covered by part in the content playlist just changes the concluding time of adding content into.
At step S007, be the center with the fresh content, along content playlist both direction traversal forwards, backwards,, then handle existing content, and continue the content of this direction of traversal, till not having conflict if there are conflict in fresh content and existing content on certain direction.The traversal of another direction is handled equally.The situation that conflict is handled comprises:
Identical, all standing: the existing content-data of deletion from content playlist;
The preceding covering: the time started of revising existing content is the concluding time of fresh content.
The back covers: the concluding time of revising existing content is the time started of fresh content.
At step S008, fresh content is inserted into the correspondence position of content playlist, make content playlist become the tabulation that increases progressively in proper order by the content play time started.Accomplish content and add function.
Specifically; When fresh content is inserted into the correspondence position of content playlist; Broadcast start time through content calculates contents view left side (contents view is the square frame of a represent content) relative displacement in time shaft; The broadcast concluding time with content deducts the playing duration that the time started obtains content, converses the width of this contents view on time shaft.For example, be under 1: 1 the situation in ratio, the width of promptly corresponding 3 pixels of per minute.Through operation, contents view is inserted in the dom tree of time shaft at last,, and on time shaft, show the new contents view that adds by the browser renders dom tree to the DOM node.
At step S009, when browser detects left frame or the left frame of certain contents view in user's click on content playlist, promptly trigger the DOM incident, this incident is caught by action listener response unit 404, then execution in step S010.
At step S010, for live type play content, the left and right side frame of view on time shaft that can be directly moves this content through mouse adjusted content broadcast time., triggers mouse the DOM incident when moving.Action listener response unit 404 is caught moving event, and playlist maintenance unit 402 calculates bezel locations, and converses with respect to the position (initial point) of the time shaft leftmost side time of this content according to frame.That is, this moment, the coordinate of mouse was exactly the coordinate of frame, and it is exactly the current time offset corresponding to initial point of this contents view that the frame coordinate deducts the origin of coordinates (the time shaft leftmost side).Be that per 3 pixels are represented 1 minute under 1: 1 the situation in ratio.For example 60 pixels are exactly corresponding 20 minutes.Then, the new content time is rendered on the time shaft, with the live content view behind the demonstration adjustment reproduction time through view rendering unit 403.
In addition, the present invention can also further realize other the function that time shaft is operated.For example
Amplification, reduction capability:, then trigger the convergent-divergent incident, and new ratio data is appended in the trigger event object according to user's operation when the user clicks the amplification of scaling chi or dwindles button.At step S011; Action listener response unit 404 obtains this incident; Therefrom extract the ratio data make new advances, with new coordinate and the width of each contents view in this axle computing time, and on time shaft new coordinate scale; This process is similar with top account form, has just done scale operation according to this ratio data.Then through view rendering unit 403 repaint time shaft with and on contents view, scale view, masking-out view etc.Thus, can make the needs amplification time axonometric drawing of user, be convenient to adjust subtly reproduction time according to oneself.When the user needs the general view time shaft, also can dwindle the time shaft view, check own content playlist on whole time shaft.
