Embodiment
Before method of the present invention is described in conjunction with specific embodiments, at first introduce the related several notions of playable media file.
Playable media file in the internet is that digital play medium is stored in the computer-readable medium with data layout, wherein play medium is a data sequence, interrupted in time, by sampling and quantification, simulation play medium conversion of signals is become the digital play medium signal of being made up of many binary numbers 1 and 0.Usually, the playable media file in the internet comprises audio file, video file, FLASH file or the like, and for example, common file layout suffix is that swf, mpg, mp4, rm, mp3, wma, wmv, ASF etc. are the types of playable media file.
Timing code is the unique time encoding at each joint/section play medium information record.The external time code file is a kind of file that has timing code and corresponding text message of corresponding play medium.Usually be presented as the lyrics of audio content or the caption information of dialogue or video content.For example .LRC lyrics file or .SUB subtitling format file etc.
For example, lyrics file
[ti: fruit juice divides you half]
[ar: flower]
[by: catkin wafts]
[offset：500]
[00:08.01] editor: catkin wafts
I want that that that that that [00:10.01]
You want that that that that that [02:24.74] [02:14.73] [01:24.74] [00:14.76]
…?…?…?…?…?…?…
Go up routine middle front part and comprise text attribute information such as some titles of the song, author, the lyrics part of back all has corresponding timestamp, the lyrics that a plurality of timestamps are arranged are the lyrics that all can show when these timestamps begin respectively, in case run into the timestamp of the lyrics that the next one begins to show, the lyrics of current demonstration promptly no longer show, that is to say that next zero-time is the termination time of the preceding paragraph lyrics.
For example, subtitle file
…?…?…?…?…?…?…
00:01:23,249--＞00:01:27,276
Do not do evil with Extra Sensory Perception, I have known, the charles
…?…?…?…?…?…?…
Subtitle file has comprised beginning and ending time and the termination time that captions show in the last example, shows the caption information of below according to above-mentioned timestamp.
Above two examples only be usually the external time code files of being seen two kinds of media files, other playable media file also is to set up such external time code file, set up different timing code files according to different demands, that is to say that the playable media file of all forms can have corresponding external time code file.
With reference to Fig. 1, be the process flow diagram of a kind of searching method at playable media file of the present invention, may further comprise the steps:
Described information is obtained and generally can be comprised and download to local and the online playing dual mode, and following description is generally adopted download to come expression information to obtain and described.
Relate to server end and client in the searching method shown in Figure 1, wherein, can be divided into following two kinds of situations:
First kind of implementation, described associated steps 101, cutting scheme determining step 103 are all finished at server end, and client is obtained the required cutting scheme of user, and then finish download according to the segmental information in the cutting scheme, obtain the fragment or the fragment combination of required playable media file.
Second implementation, only described associated steps 101 is finished at server end, and cutting scheme determining step 103, and download step 104 is all finished by client, client is obtained required playable media file link and the external time code file that is associated thereof, and then finish analysis, cutting scheme and determine, download the fragment or the fragment combination that obtain required playable media file.
Certainly in the above two kinds of cases, in order to help the user to realize retrieval, need at playable media file link and the external time code file that is associated thereof some keywords or classification index be set at server end, perhaps at the cutting scheme keyword or classification index are set at server end, but because this part is very known at search field, so just do not given unnecessary details at this.For example, the user can realize retrieval to information needed by various browsers, then by triggering the external time code file that client makes that client can be obtained the required cutting scheme of user or playable media file link and be associated.
For above-mentioned first kind of implementation, can adopt virtual cutting, be that segmental information in the described cutting scheme can be the playable media file link be associated and download terminal that client is obtained the required playable media file link of user and downloaded terminal, and then finishes download.The play medium link that certain the external time code file that obtains for virtual cutting is associated has only when user's download or when watching this section playable media file, just can and play in client downloads, and the file of reality does not have any variation.Be understandable that,, also have different requirements of combination because the user has different demands, so the cutting scheme is not unique, every kind of cutting scheme all can be stored in the search database, when the user searches for, offers user's cutting scheme corresponding with keyword.For example, the user wants to search for the pairing snatch of song of song that finds in certain live concert video file in some special editions, through after the virtual cutting, can offer the user to the video file terminal of the fragment correspondence that meets song title in this special edition, thereby make the user obtain the live concert version of song correspondence in certain special edition.Yet because different special editions has different songs, and same first song also may be in different special editions, so the user can obtain the video file terminal that all meet the fragment correspondence of song title in this special edition.
Wherein, described terminal is the beginning and ending time point of this external time code file fragment correspondence in the playable media file that is associated; Perhaps, described terminal is each packet of this external time code file fragment correspondence in the playable media file that is associated or the start-stop location point of byte.Certainly, when described terminal is corresponding beginning and ending time during point, client needs and can determine each corresponding in the described playable media file packet or the actual storage start-stop location point of byte according to described beginning and ending time point.
Definite mode of described start-stop location point can for: calculate each corresponding in the described playable media file packet or the actual storage start-stop location point of byte according to the compressed format of described beginning and ending time point, playable media file, because the audio format of standard has existed definite sample frequency and storage standards.For example, well-known, during compacted voice file, be to compress according to fixing bit rate, correspondingly, can pass through reverse conversion, calculate the position of this audio file, thereby form linear correspondence corresponding to its external time code.Preferably, can also at first obtain the file header information of required playable media file, obtain actual storage start-stop location point in conjunction with its compressed format information calculations again, but can provide how more detailed information because the file header information data amount is very little, so can improve computing velocity and precision.
In addition, definite mode of described start-stop location point can also for: call corresponding playing program, read the file header information and the part of media information of the playable media file that is associated earlier, carry out redirect according to described beginning and ending time point then, obtain byte offsets information, thereby determine each corresponding in this playable media file packet or the actual storage start-stop location point of byte, for example, Windows Media stream media technology just can realize said process.
Because the file header of audio-video document is very little, in processing, can ignore, guarantee the accurate linear corresponding of audio file and timing code so can add certain side-play amount, can obtain corresponding byte information by special software or the preprocessing process by existing media player in the reality and guarantee this linear corresponding.
For above-mentioned first kind of implementation, also can adopt actual cutting, be in the described cutting scheme segmental information can also for: the playable media file fragment that is associated or the link of fragment combination, described link are according to the fragment of described external time code the playable media file that is associated to be carried out depositing in addition after the actual cutting obtaining; Client is obtained the link of required fragment of user or fragment combination, and then finishes download.In the said process, server end has been stored peer link in advance, thereby avoided real-time calculation process, improve retrieval rate, but may bring performance, storage space to have relatively high expectations to server, bring certain wasting of resources, still very feasible at some download scenarios special or that clicking rate is higher.In a word, those skilled in the art can adopt two kinds of cutting schemes of above-mentioned proposition to select a use fully as required, perhaps are used in combination, and all belong to one of design of the present invention.
Actual cutting is exactly by tool software, comes physics cutting playable media file according to the terminal that analysis obtains, and playable media file is divided into a plurality of file fragments, thereby and deposits in addition and form new link.The user can directly click corresponding link according to the cutting scheme that retrieves and download the fragment that can obtain required playable media file.
Preferably, synthetic new playable media file of the playable media file slice groups that described a plurality of actual cuttings can be obtained.Described combination is physically, exactly the synthetic new playable media file of the slice groups of all playable media file is offered the user; Certainly, also can not make up, only set up a playlist, offer each media player, each media player can be playing continuously a plurality of files according to this playlist, and these a plurality of files are treated as a file.
For above-mentioned second kind of implementation, client is obtained required playable media file link of user and the external time code file that is associated thereof from server end, and then finish analysis, cutting scheme and determine, download the fragment or the fragment combination that obtain required playable media file.Wherein, the required segmental information of client downloads should comprise: playable media file link that is associated and download terminal, owing to only comprise the beginning and ending time point of needs in the external time code file, so the client of this moment needs and can determine each corresponding in the described playable media file packet or the actual storage start-stop location point of byte according to described beginning and ending time point, just can finish download, the existing description before correlation technique realizes is with reference to getting final product.
Below the associated steps in the method shown in Figure 1 101 is described in detail.
Described association can adopt various feasible modes to realize, for example: by with mode such as other company's cooperations in the issue playable media file with regard to supporting issue its external time code file that is associated, thereby can obtain the comparatively accurate degree of association; Perhaps,, make the external time code file that is associated, also can obtain the more accurate degree of association specially at existing playable media file.The above-mentioned introduction by manually setting up the method for linked database also can be realized related process automatically by computing machine, and for example: the mode by text cluster is carried out related with the external time code file playable media file.
Generally, the playable media file of from the internet, obtaining, for example all store the text attribute information relevant in mp3, the windowsmedia file, as author, composition, singer, special edition, title of the song, network address etc. with this document in file self fixed position.Above-mentioned text attribute information is that related web page context and/or the link information according to playable media file obtains; Preferably, also can directly from playable media file, extract, because the text attribute information in the playable media file is generally more accurate than related web page context or link information.Text cluster is meant, the fileinfo in the comparison database, and the playable media file that text attribute information is identical or similar is labeled as same class.
And for the external time code file, owing to himself being exactly text formatting or storing various text messages, so directly from file, read certain text attribute information, for example, title of the song, author, album name etc., the external time code file mark that text attribute information is identical or similar is same class.Simultaneously external time code file and playable media file are carried out text cluster, thereby the two is associated.
In practice, the external time code file that obtains preliminary polymerization by above-mentioned correlating method has a plurality of, and playable media file is relative disorderly with the incidence relation between the external time code file, thus the accuracy of the cutting scheme of influence acquisition.In this case, above-mentioned correlating method can further include: filter out the foundation of a typical external time code file as subsequent analysis in described of a sort external time code file.
Be specially, a plurality of external time code files are put together analyze, differentiate and to belong to correct text attribute information in the same class external time code file, promptly select one and be combined into a new external time code file as the cutting sample as the cutting sample or according to the correct text attribute information that determines.
The present invention can assert whether text attribute information is correct according to multiple mode or rule.For example, majority rule is thought in of a sort external time code file, frequency of occurrences height, and promptly the higher text attribute information of proportion is a correct information.Perhaps, text attribute information to each external time code file is analyzed, if the complete hit criteria of this text attribute information storehouse (information bank that forms by manual intervention, think very accurately), promptly give its higher weight, when weighted value was higher than certain threshold value, just differentiating was correct information.And for single external time code file,, then can be used as the cutting sample if the correct information that has is maximum.Certainly, the present invention does not need choosing of cutting sample done any restriction, and above-mentioned only is several optimal ways.
Because only playable media file has been carried out text cluster in the said method, also can there be the different playable media file of more details in the same class, for can being put according to the beginning and ending time of described typical external time code file, all playable media file that are associated come cutting, the present invention can also be on the basis based on above-mentioned correlating method, certain rule is set filters playable media file, described filtering rule can be provided with according to various search needs, and the present invention does not need this to limit.Perhaps, the present invention can also be provided with the playable media file that is used to search for source, for example, only chooses or official provides etc. from specific website, thereby can guarantee the consistance that playable media file is higher.
Below the analytic process at the external time code file in the method shown in Figure 1 is described in detail.
Owing to have the music lyrics in the external time code file, video caption or the like text message, can think information to this section playable media file, we just can know what current audio frequency or the general contents in the video be by analyzing these information, thereby can realize the fragment search to the playable media file that is associated.In the present invention, the analytical approach that the external time code file is analyzed can comprise text analyzing, semantic analysis, language model analysis or participle analysis.
Wherein, text analyzing is that the text message of external time code file is analyzed, and obtains the emphasis key element of text message.When being applied in the reality, for example, when needs were searched for the climax fragment of audio file, its analytic process may further comprise the steps: the identification parameter of described external time code file being determined to comprise multiplicity by text analyzing; Described identification parameter can also comprise the time of repetition paragraph, repeated segments etc., can be provided with according to demand; Give corresponding weighted value according to described identification parameter to each fragment of described external time code file, weighted value according to each fragment sorts to each climax fragment, for example, time length according to multiplicity and repetition paragraph is marked, sort then, the fragment that score is the highest is preferred climax fragment.The present invention is for there being different two or more climax fragments also to support in the audio file.Certainly, can also analyze the key element fragment of various playable media file according to demand, for example,, analyze the different chapters and sections of an audio or video lecture etc. by interrupt unit according to such text analyzing.
Semantic analysis is meant by the semantic relation between notional word and the notional word in the text structure of analyzing the external time code file, judge the roughly meaning of a certain section or several sections text representations, give the text semantic keyword respectively, this semanteme keyword can comprise the literal that occurs in this section text, also can be with the most close literal of this section text semantic, the searching key word of described keyword respective user.
The participle analysis is meant by the text message to the external time code file carries out participle, gives corresponding keyword respectively, and the searching key word of described keyword respective user can also form related keyword jointly in conjunction with semantic analysis.
The language model analysis classes is similar to semantic analysis, does not repeat them here.
In a word by above-mentioned analytic process, can determine the fragment of a plurality of required external time code files, and also can give corresponding keyword for each fragment by above-mentioned analytic process.For determining fragment and the process of giving keyword, can realize by multiple analytical procedure.Certainly, for client is finished analytic process, be not need to give corresponding keyword.
