Embodiment
In order to make those skilled in the art person understand better the technical scheme in the application, below in conjunction with the accompanying drawing in the embodiment of the present application, technical scheme in the embodiment of the present application is clearly and completely described, obviously, described embodiment is only a part of embodiment of the application, rather than whole embodiment.Embodiment based in the application, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all should belong to the scope of the application's protection.
Referring to Fig. 1, the figure shows the flow process of an embodiment (embodiment mono-) of the video content interactive approach that the application provides, this flow process comprises:
Step S101: video resource server receiving target video playback request;
Step S102: video resource server provides target video data according to target video playing request, and the Search Results that returns to the expansion of based target video data according to target video data, to load in playing process according to the selection of the Search Results of expansion is represented to selected Search Results at target video.
Video resource server in this embodiment can be used for providing video resource (being target video data), based on actual needs, can be on this server integrated various corresponding functions or by calling other Implement of Function Module specific purpose." video resource is provided " described here do not represent that this server must be the direct producer of video resource, and just show by this server realize and video playing terminal between information interaction, video resource on this server can be that it directly produces, such as, the video that video resource server managers oneself is uploaded; Also can from other servers, obtain and store on this server temporarily.In actual moving process, the application's video resource server preferably adopts CDN(Content Delivery Network, content distributing network) node server.The basic ideas of CDN are to avoid as far as possible affecting on the Internet the bottleneck of data transmission bauds and stability, make content delivery obtain sooner, more stable.By place this CDN node server everywhere at network, can be formed in the intelligent virtual network on Internet basic, thereby can be in real time according to the connection of network traffics and each node, load state and to integrated informations such as user's distance and response times, user's request be directed to again on the nearest node server of user, at nearest node server during to user's return data, also can make user obtain required content nearby, improve the response speed that user obtains related resource.
" Search Results " in this embodiment is different from the generic search obtaining by search engine in general sense, and it exists the feature of three aspects:: the one, Search Results be " based on " target video data.This shows the being closely related property of Search Results and target video, because the application need to realize the interaction of video content, if the instead easily normal interaction of impact of all Search Results about this video is provided, user to video playing terminal forms excessive interference, and the Search Results of based target video data has been got rid of the video information which specific aim is strong, relevance is weak and entered into mutual environment, reduce or can not form bad impact to the interaction of normal aspect.The 2nd, the acquisition of Search Results " dependence " is in target video data, this be different from traditional first by people for watching target video to obtain " watching focus ", by people, by " watching focus ", the intelligence by people is converted into searched key word again, then take this keyword as the process according to carrying out manual search.The 3rd, Search Results is the Search Results of " expansion ", the Search Results of the expansion here has the implication of two aspects: for target video, what at video terminal, represent is no longer only target video itself, also comprise the related information being closely related with target video, realized " expansion " of target video; For follow-up selected Search Results, the needs based on interactive, the related information finally representing in video playing terminal is not whole Search Results, but a part for Search Results, therefore, the former is " expansion " with respect to the latter.For the ease of distinguishing two concepts and embodying above-mentioned intension, the application is called the Search Results of based target video data " Search Results of expansion ", the Search Results showing is called " selected Search Results ".
Above-described embodiment is by the analysis to target video playing request, obtained the Search Results of the expansion of target video data and based target video data, then at target video, loaded in playing process according to the selection of the Search Results of expansion is represented to selected Search Results.This technical scheme in terms of existing technologies, has obtained many-sided technique effect:
(1) scheme of the present embodiment is by providing the Search Results of expansion can provide perfect as far as possible target video related information, the user who has expanded screen playback terminal obtains the probability of more related informations of based target video, these related informations can be presented as the polytypes such as text, picture, audio frequency, video, animation, make video playing terminal no longer only obtain the target video of single form and single content, thereby greatly strengthened the rich of video content interaction;
(2) Search Results that the scheme of the present embodiment finally represents in video playing terminal depends on the selection to expanded search results, user can select suitable content according to self interest like this, although get rid of that based target video data obtains but be not which " interference " information that user is concerned about the most, make the content representing can meet more user's needs, there is good specific aim, thereby improved the accuracy of video content interaction;
(3) Search Results that the scheme of the present embodiment represents in video playing terminal is the result that based target video data search itself obtains, user not in the same time, the target video clicked under mood, environment is different, the different Search Results that obtain of target video of user's program request are also by difference, make video playing terminal can represent current real time correlation information, thereby strengthened the ageing of video interactive;
(4) scheme of the present embodiment is in realizing video content interactive process, extensive work transfers to server end to carry out, video playing terminal side only needs the Search Results of expansion to select to confirm, and do not need relevant information for obtaining target video to search for separately or search again as traditional keyword forming based on " watching focus ", reduce numerous and diverse degree that user uses, thereby strengthened the convenience of video content interaction.
In the step S102 of above-described embodiment, according to target video playing request, obtain after target video data, the prerequisite of this operation of Search Results of carrying out returning according to target video data the expansion of based target video data is the Search Results that first gets the expansion of based target video data.In actual application, the Search Results that obtains the expansion of based target video data can form in conjunction with different technology multiple specific implementation.Such as, can first from target video data, extract the data about target video classification, with this, determine the classification of target video, then according to this classification, obtain the Search Results of the expansion of based target video data, the classification here can be the classification (as documentary film, TV play, variety show, topical news etc.) of subject matter, can be also the classification (as political class, economic class, cultural class, law class, educational etc.) of content.Suppose that the type by the definite target video of the data of extraction is documentary film, cultural class, can be directly descriptor using documentary film, cultural class as video keyword, the video resource that in the video resource of storing on video resource server, retrieval and this classification match is as the Search Results of expansion; Also the specific video keyword of Characteristics creation that can be based on " documentary film ", " cultural class ", is submitted to this keyword in search engine and automatically retrieves, the Search Results using the result of retrieval as expansion.
Also such as, can be based on image analysis technology, to realize the Search Results of above-mentioned acquisition expansion.Because video resource is view data, can first to target video data, resolve and obtain video pictures data endlessly, then transfer to image analysis system to analyze these video images, image analysis system can adopt the modes such as pattern recognition to analyze target video data, describe, classification and explanation, final generating video keyword, again these video keywords are submitted in search engine and are searched for, search engine is according to certain strategy, use specific computer program search information from the Internet, again information organized and processed, then provide the Search Results of expansion.
At the above-mentioned Search Results that gets the expansion of based target video data, can return to video playing terminal on the basis of Search Results of expansion, interactive for further augmented video content, can take many-sided measure.For simplicity, provide two kinds of schematic measures below:
The one, after generating video keyword, first this lists of keywords is returned to video playing terminal, after being selected by video playing terminal, then transfer to video resource server according to selection result, to search for the Search Results that obtains expansion.In actual moving process, although based target video data can generating video keyword, and based on this keyword search Search Results that is expanded, but, in these video keywords, may have some keyword is not that user wants the content of being concerned about at all, and the Search Results that the video keyword based on such obtains is the also final expectation of the unlikely user of meeting naturally.For this reason, the video lists of keywords of generation first can be transferred to the user of video playing terminal to select to confirm, then according to selecting the video keyword of confirming to search for, because video keyword is selected to determine by user, the Search Results that makes to obtain like this can improve the probability of " hitting " user view greatly.In addition, this mode can also reduce the burden of video resource server, the all videos keyword that video resource server need not be generated based target video data is searched for, and only to user, selects some video keyword of determining to search for, and has saved calculation process resource.
The 2nd, before video resource server returns to the Search Results of expansion to video playing terminal, judge whether to receive the interactive message that triggers of video content, only in the situation that receiving, just carry out the Search Results that returns to expansion.The interactive triggering of video content message can embody the user's of video playing terminal " intention ", in some cases, possible user does not wish carrying out sometime video content interaction, at this moment, the Search Results that returns to expansion to user may have influence on user's normally watching target video, therefore, can arrange and open or close " switch " (local switch) that returns to the Search Results of expansion to user, when receiving that user's content interaction triggers message, " switch " is in opening, confirm that thus user is desirable to provide the extend information except target video, otherwise " switch " in closed condition, confirm thus that user is current and do not wish to receive the extended message outside target video.
It should be noted that, the operational depth that the time point different video Resource Server side that whether the interactive triggering of video content message is received is here carried out may be different.Such as, when obtain target video data according to target video playing request in or before do not receive that video content triggers message in during this period of time, can not carry out resolving according to target video data operation and the subsequent operation thereof that obtains vedio data; When after vedio data obtains in generating video keyword or before do not receive the interactive triggering of video content message in during this period of time, can not carry out searching for acquisition Search Results or not carrying out the operation according to vedio data generating video keyword according to video keyword.In a word, can be in the situation that not receiving that video content is interactive and triggering message, suspending video resource server is the every operation that video content interaction is carried out, when follow-up certain when constantly having received that video content is interactive and having triggered message, proceed these operations.
Here need to discuss a kind of special circumstances: originally user does not open video content interaction " switch " what watch video, be that video resource server is not received the interactive message that triggers of video content, video playing terminal is normally carried out the broadcasting of target video, but after being played to a period of time, user wants again to understand the extend information about target video, opened video content interactive " switch ", at this moment video resource server will be received the interactive message that triggers of video content, the aforementioned operation stopping being recovered or be carried out, in this case, in the step of aforementioned " obtaining expanded search results according to target video data ", be according to whole target video data, still only according to receiving that the interactive target video data of message after the moment that trigger of video content obtains Search Results.In fact, generally, if user opens video content interactive " switch " at the halfway of playing target video, explanation content before this may not be the interested content of user, at this moment the foundation using one section of target video data having play as search extension information also, may cause the accuracy of Search Results, specific aim to reduce.For this reason, the application is in such cases, preferably only will receive that the interactive target video data of message after the moment that trigger of video content is as the foundation that obtains the Search Results of expansion, to receiving that video content triggers the target video data of message after the moment and resolves acquisition vedio data, and then analysis vedio data generating video keyword in such cases, the Search Results being expanded based on this keyword search.
The measure of above-mentioned two kinds of augmented video content interactions that provide, both can be used separately, and use also can combine.While using when combining, by judging whether to receive that video content interaction triggers message and identifies the measure whether user needs to carry out video content interaction, realized interaction for the first time, this interaction is " greatly " interaction, determines the current target video extended message that whether needs of user; The measure of selecting for user by video keyword being returned to video playing terminal, realized interactive for the second time, this interaction is " little " interaction, in the situation that definite user need to carry out video content interaction, by user, further determined whether the video keyword of the current propelling movement of custom system is its keyword corresponding to extend information needing.By this twice interaction, make final expanded search results more meet user's expectation, improved the specific aim of video content interaction.
In fact, above-mentioned the second interaction mode of mentioning, the time that this can also be operated in is upper further in advance, advances to video resource server is received in target video playing request.After the request of video resource server receiving target video playback, by the identification to target video playing request, determine whether video playing terminal needs to carry out video content interaction, if needed, carry out about interactive sequence of operations, if do not needed, in whole target video playing process, acquiescence is not carried out the interactive operation of video content, this is equivalent to be provided with one " master switch " (certainly, this master switch can change state by the aforementioned local switch of mentioning, such as, in the situation that " master switch " forbidden carrying out screen content interaction, in target video playing process, receive the interactive message that triggers of video content, be that local switch is opened, the default conditions of at this moment master switch setting will change).During specific implementation, whether a field bit in target video playing request, being specifically designed to sign needs that video content is interactive to be triggered if can being set, when this flag bit be true time (such as, the value of flag bit is " 1 "), illustrate that the user of video playing terminal wishes to carry out the interaction of video content; When this flag bit be fictitious time (such as, the value of flag bit is " 0 "), illustrate that the user of video playing terminal does not wish to carry out the interaction of video content, does not carry out the associative operation of video content interaction.From the above, by video content is set in target video playing request, trigger the effect that flag bit can start " master switch ", when this switch open, in whole target video playing process, can carry out the interaction of video content, otherwise, do not carry out video content interaction.Certainly, in actual mechanical process, as previously mentioned, aforesaid " local switch " and " master switch " here can be combined, when master switch is set to carry out video content interaction, also allow user constantly to arrange and forbid video content interactive operation temporarily at some; When master switch is set to not carry out video content interaction, also allow user constantly to arrange and carry out video content interactive operation at some.Can meet the various needs of user under different situations completely like this.
For the application's technical scheme is described, below again with one more specifically embodiment (embodiment bis-) the application's technical scheme is explained.Referring to Fig. 2, the figure shows the flow process of this embodiment.This flow process comprises:
The request of step S201:CDN node server receiving target video playback, described target video playing request comprises the interactive flag bit of video content;
This step arranges special field in common target video playing request, for sign, whether needs to carry out video content interaction.During specific implementation, can provide interface or special purpose interface are set, the user of video playing terminal is at this interface or by special purpose interface, flag bit is set, and by the equipment of being responsible for sending target video playing request to CDN node server, this is arranged to content and is encapsulated among video playback request.
Step S202:CDN node server provides target video data according to target video playing request;
Step S203: judge whether the interactive flag bit of video content in target video playing request is set to very, if so, perform step S204; If not, perform step S203(a): target video data is play;
This step is for detection of the facilities of the interactive flag bit of video content in target video playing request, if this is masked as very, the user who determines video playing terminal wishes to carry out video content interaction, carries out in this case the step about video content interaction; Otherwise, do not wish to carry out video content interaction, directly return to target video data and play to video playing terminal.It should be noted that: step S202 is " public " step, no matter whether need to carry out video content interaction, all need to return target video data, to complete normal video playback capability, just in the situation that user selects to carry out video content interaction, except carrying out common video playback, also carry out the representing of Search Results of based target video data.Consideration based on such, in fact after step S202 also can be placed on step S203, judging whether target video playing request has after the interactive flag bit of video content, if flag bit is true, CDN node server provides target video data to carry out target video broadcasting to video playing terminal, simultaneously or carry out afterwards the correlation step of video content interaction, the Search Results of based target video data represents to user the most at last; If be masked as vacation, CDN node server provides target video data to carry out normal target video playback to video playing terminal.
The HTTPLive Encoder that step S204:CDN node server calls HLS resolves and obtains vedio data target video data;
HLS is the abbreviation of Http Live Streaming, represents HTTP streaming media live broadcast technology, and this technology realizes video playback based on HTTP streaming media communication agreement.It is divided into a string little file download stream based on HTTP by overall data stream, each short block download loading as an embed wholly among unlimited transmission data flow.In HLS, include HTTPLiveEncoder service, this service is the kernel service that in HLS, video content turns encapsulation in real time, by this service, target video data can be resolved and be obtained vedio data.Here CDN node server calls the HTTPLiveEncoder service of HLS, can be intrinsic call, also can be external call, the former refers to directly the functional layer of HTTPLiveEncoder service is embedded among CDN node server, by being similar to the form in call function storehouse, directly calls; The latter refers to that HTTPLiveEncoder service is as being independent of the functional entity outside CDN node server, when CDN node server needs by this functional entity of relevant interface interchange to realize the function of needs.
Step S205:CDN node server calls image analysis system vedio data is carried out to pixel and image analysing computer generating video keyword;
By abovementioned steps, obtain after vedio data, the correlation function that CDN node server calls image analysis system carries out multifaceted analysis to vedio data, and this analysis can be pixel analysis, can be also image analysing computer, or the combination of the two.Analysis by picture system obtains a series of video lists of keywords, and then this lists of keywords can be transferred to next step step to carry out retrieval.Certainly, also can this video lists of keywords be returned to the user of video playing terminal as previously mentioned, by it, video lists of keywords be selected, then the result of selection is returned to CDN node server, then enter the step of retrieving according to selected video keyword.
Step S206:CDN node server calling search engine is searched for the Search Results being expanded, and return to the Search Results of the expansion of based target video, to load in playing process according to the selection of the Search Results of expansion is represented to selected Search Results at target video;
After obtaining video lists of keywords, CDN node server can calling search engine be searched for.When searching for, the database of search can be the Database Systems of CDN node server self maintained, to carry out " local search ", can be also that these video keywords are submitted to special network search engines, by these search engines, realize search mission.After having searched for, CDN node server returns to Search Results the user of video playing terminal by HTTP passage, then can provide program interface, by user, these Search Results be selected, the mode that the Search Results that user is selected represents with various close friends displays.
The video content interactive approach that foregoing is mentioned is mainly the description of carrying out from video resource server side, and in fact, the application also provides the video content interactive approach embodiment (embodiment tri-) describing from video playing terminal side.Referring to Fig. 3, the figure shows the flow process of this embodiment.This embodiment comprises:
Step S301: video playing terminal sends target video playing request, so that video playing terminal to distolateral, according to target video playing request, provide target video data, and the Search Results that returns to the expansion of based target video data according to target video data;
Step S302: video playing terminal loads in playing process according to the selection of expanded search results is represented to selected Search Results at target video.
The present embodiment can be obtained the technique effect of previous embodiment equally, can carry out various improvement to obtain the implementation of various distortion to this embodiment equally.For avoiding repetition, no longer narration here.Mainly for video playing terminal, after the Search Results that obtains target video and based target video data, how to represent and discuss below.
In the situation that user need to carry out video content interaction, video playing terminal will obtain the data of two aspects: the one, for normally realizing the target video data of video playback; The 2nd, for realizing the interactive selected Search Results obtaining of video content.When the data of this two aspect are play in same video playing terminal, the problem that exists resource " coordination " to utilize.Such as, if selected Search Results is also a video, in the video of current broadcasting, play so selected video, will there is resource contention, cause utilization of resources conflict.For this reason, must both broadcastings of overall arrangement (or representing).In actual moving process, the broadcasting of realize target video and the coordination of selected Search Results represent can there is multiple concrete mode, the application provides two kinds of exemplary implementations here, and those skilled in the art can expand the various modes that correspond to actual needs on this basis according to the application's goal of the invention:
The one, according to the type of selected Search Results, distinguish and represent.Why distinguish and represent, because the concrete form of the Search Results of based target video data may be widely, such as, can be news, consulting, multimedia, animation, picture etc., whether between dissimilar Search Results and the target video of broadcasting, exist conflict and the conflict depth all not identical, difference represents can dissolve according to the feature of different Search Results determines optimal ways of presentation.
The 2nd, selected Search Results is represented in preset fixed position.Because the broadcasting of current goal video is the main task that video playing terminal need to realize, not representing of selected Search Results should affect or hinder completing of this main task, therefore, the representing position and can be arranged on the corner location that completes the less video playback forms of impact on main task of Search Results, because the normal conditions based on video playback, video content in video playback forms center is normally crucial, critical content, and the video content of corner location is normally complementary, or, opening completely separately forms represents, open separately forms, be equivalent to reopen a processing threads, in the situation that processor calculating ability corresponding to video playing terminal is not too poor, conventionally can mutually not hinder each self-operating of ground.
Certainly, best mode is that above-mentioned first kind of way and the second way are combined.Such as, first the classification of selected Search Results is distinguished, then according to the selected different preset position of different classifications, represent, particularly:
When selected Search Results is text type, because no matter the Search Results of text type does not all form larger conflicting with current video playback in voice resource and picture resources, in this case, shown in Fig. 4 (a), the edge that Search Results can be arranged on to the screen of playing target video represents." edge " can be the corner of any target video screen, because even if these are local covered, the normal play of target video is not caused to crucial impact yet, such as, can be top edge (as shown in phantom in FIG.), lower limb or left and right edges, the horizontal stripe form of usining be rolled and is represented the word as Search Results.Like this, the user at video playing terminal place on the one hand can be by watching target video normally to understand the content of video, can obtain on the other hand the word class extend information relevant to video, the picture of current broadcast, thereby meet the requirement such as ageing, rich, convenience of video content interaction.
When selected Search Results is picture/mb-type, because picture/mb-type need to occupy certain locational space conventionally, at this moment picture may form resource contention with the target video of current broadcasting, picture need to be placed on to specific position, this specific position can be another independent forms of breakaway video playback forms, also can be the part in target video is play forms, or have the relative position of less overlapping area with target video broadcast window.Generally speaking, can select the position of placing according to the size of picture, if picture is smaller, the present target video of photo exhibition can be loaded to four corner locations (referring to Fig. 4 (b)) of the forms of playing, because these positions are conventionally less on the broadcasting impact of target video; If picture is larger, is preferably in an independent position and represents.
When selected Search Results is audio types, because audio frequency need to take sound channel, video with current broadcasting is carried out to direct conflict the in resource, therefore, can suspend to load and play target video, and the Search Results of loading audio plays type, after this Search Results finishes, then broadcasting automatic or that artificially switch back former target video.
When selected Search Results is video type, reason based on identical with above-mentioned audio types, can suspend the loading of current goal video is play, the Search Results to video type within the scope of target video broadcasting represents (referring to Fig. 4 (c)), forms " picture-in-picture ".
Except the above-mentioned classification according to Search Results and preset position represent, in actual application, also may need to arrange a control strip, by this control strip, control representing position, representing the work such as progress of Search Results.
