Step 201, terminal shows input module, and according to the input for carrying search term obtained from the input module Content generates searching request, and search term is carried in the searching request；

Search term is the sentence of the caption content in the subtitle file for searching multimedia files, can include at least one Individual word.For example search term can be " we " or " Ching Ming Festival outgoing sweep a grave " etc..

Terminal shows input module in interface, and the input content for carrying search term is obtained by input module.Tool Body, when input module is word input module, terminal can obtain the word letter that user inputs in word input module Breath, the text information is defined as carrying to the input content of search term, the search term is carried according to input content generation Searching request, or, when input module is phonetic entry component, terminal can obtain the voice signal that user sends, will The voice signal is defined as carrying the input content of search term, and the search of the search term is carried according to input content generation Request.

, please according to the input content for the carrying search term generation search obtained from the input module in the present embodiment Ask, including：

1）If multimedia file is currently played in terminal, the file identification of input content and the multimedia file is added It is added in searching request；

2）If terminal does not play multimedia file currently, input content is added in searching request；

Wherein, input content is the text information for carrying search term or the voice signal for carrying search term.

When playing multimedia file in the page of terminal current presentation, terminal can get the multimedia file File identification, input content and this document mark are added in searching request together, search term now is used for current Caption content in the subtitle file of the multimedia file played scans for.

When not playing multimedia file in the page of terminal current presentation, terminal can not get the text of multimedia file Part is identified, and input content is added in searching request, and search term now is used for all multimedia files in server Caption content in subtitle file scans for.Due to by do not carry file identification search for generally can be in server All multimedia files are matched, and expand the seeking scope to caption content, improve the accuracy of content obtaining.

Step 202, terminal to server sends the searching request for carrying search term；

Wherein, terminal sends searching request by cable network or wireless network to server.

Step 203, the searching request for carrying search term that server receiving terminal is sent；

Because what may be carried in searching request is text information, it is also possible to carrying is voice signal, therefore, server Also need to handle searching request, to obtain search term.Wherein, server is received eventually by cable network or wireless network Hold the searching request sent.

Specifically, the searching request for carrying search term is received, including：

1）The searching request for carrying text information is received, search term is extracted from text information；Or,

2）The searching request for carrying voice signal is received, search term is extracted from voice signal.

Wherein, if what is carried in the searching request that terminal is sent is text information, server can be directly from the search The text information is extracted in request, using the text information extracted as search term；If what is carried in searching request is voice Signal, then server the voice signal can be converted into text information, using the text information after conversion as search term.

Step 204, server obtains the subtitle file of multimedia file, and the subtitle file corresponds at least one language； The sentence in the subtitle file is split into keyword according to preset rules；If subtitle file is one, by each keyword And there is corresponding one index of generation at the time of keyword, obtain index database；If subtitle file is at least two, by difference In subtitle file with same words anticipate and with it is identical go out current moment every group of keyword and the moment generate one index, obtain To index database；

In the present embodiment, server receives the captions text of multimedia file and the multimedia file that third party device uploads Part, and multimedia file and subtitle file are handled respectively, the content obtained after processing is carried out corresponding to file identification Storage.

When handling multimedia file, multimedia file is converted to multiple format by server, respectively will conversion The multimedia file of the different-format obtained afterwards corresponds to same file mark and stored.For the ease of distinguishing different-format Multimedia file, also the multimedia file of different-format is numbered server, such as, file identification is a multimedia File includes AVI（Audio Video Interleaved, Audio Video Interleaved）The multimedia file and MPEG of form （Motion Picture Experts Group, Motion Picture Experts Group）The multimedia file of form, then can be by AVI format The numbering of multimedia file be arranged to 1, the numbering of the multimedia file of mpeg format is arranged to 2.Converted in form Afterwards, multimedia file is arranged to can play state.

When handling subtitle file, for each sentence in subtitle file, server is according to preset rules pair Word included by the sentence is split, and each word that fractionation obtains is defined as into a keyword.Due to subtitle file At the time of being also provided with the appearance of each sentence, therefore, the moment can be defined as each keyword in the sentence by server Appearance at the time of, by one index of a keyword and the corresponding generation of moment, obtain index database.Assuming that preset rules are Keyword be in dictionary with clear and definite lexical or textual analysis word and sentence be " we have a meal together ", then the keyword for splitting to obtain is " we ", " together " and " having a meal ", if be at the time of the appearance of the sentence 1 point 30 seconds, index 1 is " we -1 point and 30 seconds ", Index 2 be " -1 point 30 seconds together ", index 3 is " have a meal -1 point and 30 seconds ".

Multimedia file may have the subtitle file of at least two different languages, such as Chinese subtitle file and English subtitles File etc..Wherein, different subtitle files are identical in sentence sentence meaning mutually in the same time, then server is in different subtitle files After sentence meaning identical sentence is split, one group of keyword will be defined as with the keyword that same words are anticipated, and the group is crucial Corresponding one index of generation, obtains index database at the time of the appearance of word and this group of keyword.Assuming that 5 points in Chinese subtitle file Sentence at 29 seconds is " we have a meal together ", then the keyword for splitting to obtain is " we ", " together " and " having a meal ", English words Curtain file in 5 points 29 seconds when sentence be " We eat together ", then the keyword for splitting to obtain be " We ", " eat " and " together ", " we " and " We " are now defined as one group of keyword, then index 1 as " our-We-5 divide 29 seconds ".Together Reason, 2 is indexed as "-Together-5 points 29 seconds together ", index 3 is "-the eat-5 that has a meal divides 29 seconds ".

Further, for the ease of distinguishing the subtitle file of different language, also subtitle file is numbered for server.Than Such as, the numbering of Chinese subtitle file is 1, and the numbering of English subtitles file is 2, then indexes 1 as " 1 our -2We-5 divide 29 seconds ", Index 2 is " 1 together -2Together-5 point 29 seconds ", and index 3 is " 1 have a meal -2eat-5 points and 29 seconds ".

Wherein, step 204 only needs to perform before step 205, and the present embodiment does not limit step 204 and step 201, step Execution sequence between rapid 202 and step 203.

Step 205, server searches the index matched with search term in default index database, and the index includes and search Occur at the time of word matches, during the subtitle file that should at the time of match with search term be broadcasting multimedia file search term when Carve；

Server is matched search term with least one index in the index database of generation one by one, is obtained and the search The index of word matching.Specifically, if index is additionally included in the keyword of the subtitle file occurred constantly, in default index database The index that middle lookup matches with search term, including：

1）For each index in index database, whether there is and search term identical keyword in detection index；

2）If detect to exist and search term identical keyword, it is determined that the index matches with search term.

When each index in search term and index database matches, during server can detect search term and index Including keyword it is whether identical, if search term is identical with keyword, it is determined that the index matches with search term；If search term with Keyword is different, it is determined that the index and search word mismatch.

Due to there may be keyword and search term matching in multiple indexes, therefore, in order to improve the accuracy of matching, The index that can also be matched to keyword with search term screens.Specifically, if carrying voice signal in searching request, It is determined that index matches with search term, including：

1）The characteristic information of the audio file of multimedia file is obtained, and obtains the characteristic information of voice signal；

2）Detect the characteristic information for whether including matching with the characteristic information of voice signal in the characteristic information of audio file；

3）If detecting, the characteristic information of audio file includes the characteristic information matched with the characteristic information of voice signal, At least one index determined is screened at the time of then according to corresponding to the characteristic information of matching；

4）The index filtered out is defined as the index matched with search term.

Wherein, the method for screening server index has many kinds, such as, server matches go out the voice signal in audio text At the time of in part, the index including the moment is filtered out from least one index, the index filtered out is defined as and searched for The index of word matching；Or, server reads each index at the time of include, and the sound after the moment is intercepted in audio file Whether frequency fragment, detection voice signal match with the audio fragment, if detecting, voice signal matches with the audio fragment, will Index is as the index filtered out corresponding to the audio fragment.

Specifically, when being matched to voice signal and audio file, the audio file of multimedia file can be obtained Characteristic information, and obtain the characteristic information of voice signal, whether detect includes and voice is believed in the characteristic information of audio file Number characteristic information matching characteristic information, if detect audio file characteristic information include and the feature of voice signal letter Cease the characteristic information of matching, it is determined that audio file matches with voice signal, can obtain corresponding to the characteristic information of matching Moment, at the time of are defined as into voice signal in audio file the moment；If detect in the characteristic information of audio file not The characteristic information matched including the characteristic information with voice signal, it is determined that audio file mismatches with voice signal.Wherein, it is special Reference breath can include at least one of wave band and finger print information, due to by characteristic information to voice signal and audio file The flow matched is existing procedure, and the present embodiment does not repeat.

Step 206, server sends broadcast information to terminal, and the broadcast information is broadcast from this moment for triggering terminal Put multimedia file；

When only one index matched with search term, at the time of server can read the index and include, triggering is eventually End plays multimedia file from this moment.Wherein, when prestoring multimedia file in terminal, now server can be to Terminal sends index, saves flow caused by sending multimedia file again and wastes；When the multimedia file that do not prestored in terminal When, now server can send index to terminal and play content, and the broadcasting content includes whole multimedia files and whole Subtitle file, or, the broadcasting content include part multimedia file and part subtitle file from this moment.

When the index matched with search term is at least two and each index includes a moment, can not now determine At the time of obtaining broadcasting multimedia file, server can select a rope according to predetermined policy from least two index Draw, the index of selection is sent to terminal, the predetermined policy can include selection acquiescence index and selection search temperature highest At least one of index.Or each index can be sent to terminal by server, be selected by terminal-pair index.

First, if searching request also carries the file identification of multimedia file, broadcast information is sent, including：
