Description
Technical field
The present invention relates to computer software technology, be specifically related to a kind of media player and characters input method thereof.
Background technology
Along with the development of integrated circuit technique, when the processing power of integrated circuit (IC) chip constantly strengthens, cost is but in continuous reduction.Therefore, except traditional computing machine that carries out conventional data processing, there are now more and more technical embedded devices, due to advantage and the comparatively single-minded function and usage thereof of embedded device on cost, obtained in recent years significant progress.
In embedded device application, although along with the development of software and hardware technology, the function of its processing power and man-machine interaction is improving constantly and perfect, but be limited by the many reasons such as its cost, small product size size, construction cycle and market outlook, the arithmetic capability of its process chip and the size of storage space are still severely limited than multi-purpose computer conventionally.In this case, the application software using in embedded device, volume conventionally comparatively pocket and function is simplified relatively, thereby just has inconvenience in the time of application.For example, current widely used various handheld terminal on the market and digital entertainment equipment (being hereinafter referred to as embedded device), as Mp3, Mp4 player, digital TV set-top box, mobile phone, handheld game machine, personal digital assistant (PDA), Global Positioning System (GPS) (GPS) navigating instrument etc., all need to carry out character input under the scene of the information retrieval of being everlasting---such as at Mp3, in Mp4, search for audio-video document, in GPS navigation instrument, search for road, the title in place, and by digital TV set-top box searching TV program title or channel designation etc.
Under prior art, described information retrieval is normally undertaken by following two separate steps:
Steps A: use various data inputting methods to carry out character input, obtain the character information at least being formed by a character---, preset character database, user carries out character input by modes such as phonetic, stroke combination, hand-written even phonetic entries, and embedded device carries out descending sort and selects for user meeting the candidate characters of initial conditions or character combination according to the priority of frequency of utilization.The input method of partially embedded equipment also has associating input function, completing last time character user inputs and selectes after candidate characters, by showing according to the frequency of utilization of this character combination with all characters of described last time character formation character combination in character database, to save user's input operation number of times and to improve input speed; In addition, also have the input method of partially embedded equipment dynamically to upgrade character database according to user's input results, for example user is in character database beyond existing phrase or phrase, get up to input from being about to several character combinations, system will, using new phrase or the phrase of this character combination initial character in described character combination, be added in the middle of described character database; Afterwards, in the time that this character occurs as initial character again, will be using this character combination as a candidate item, jointly show as candidate entries with existing other phrase or phrase using this character as initial character in character database, select for user.
Step B: utilize the character information of steps A input to retrieve target database.Described target database is the address adopting in order to distinguish character database, under different application scenarioss, it may represent different implications, such as: if retrieve music file in Mp3 time, described target database refers to the set that comprises all music file titles, if retrieve place name in GPS navigation instrument time, described target database refers to the set of all geographical indication titles that comprise in map datum bag, and if in the time watching TV when searching TV program title or channel designation, described target database refers to the set of television programme title or the set of channel designation, because its concrete meaning comprising under concrete application scenarios is can be for known in those skilled in the art, therefore will make an explanation no longer one by one below.
The concrete grammar of described retrieval is: according to the character information of described input, the index of the data entries in target database is identified to the retrieval of word for word mating.That is, in target database, all data entries that the initial character of search index mark mates with the initial character in the character information of described input; In all index marks that are retrieved, all data entries of second character match in the character information of all second characters of further retrieval and described input again, constantly repeat this retrieval matching process, until all characters in the character information of described input are completed to retrieval coupling, obtain final result for retrieval.
In actual applications, above-mentioned two steps can also be carried out cross-application, such as character of every input in steps A, just trigger step B and retrieve coupling, for example, and when step B retrieves coupling, user can also further upgrade (continuing the new character of input) to character information; Or, can also for example, by Chinese character and its first letter of pinyin being carried out to corresponding (" frequently " corresponding " p ", " frequency " correspondence " pl "), realize the fuzzy query function of Chinese data entries being retrieved by input English character.To this, in prior art, there is the various retrieval form of maturation and kind, this is no longer going to repeat them.
Although it is various informative to be applied to mode of operation and the operation interface of the information retrieval in embedded device in prior art, its actual flow process of retrieving still all belongs to previously described steps A, the defined basic procedure of B or its expansion.Along with the continuous enhancing of embedded device function and capacity improve constantly, the content of preserving in equipment and information quantity are also more and more, user is more and more difficult to complete and remembers exactly the title of all information, randomness and the randomness of carrying out information retrieval are increasing gradually, and this can cause the retrieval mode of prior art to occur in actual applications variety of issue:
First, along with the increase of data entries quantity, user is difficult to remember the initial character of all data entries, the detection that existing retrieval technique must depend on initial character could realize, and user forgets the title of complete target information entry sometimes, but likely can remember some fragments in its title, existing retrieval mode cannot utilize the suggesting effect of these information to carry out information retrieval, and intelligent degree is not high;
Secondly, this method for information retrieval belongs to retrieval passive, closure---by user inputs character information, then in all data entries, retrieve coupling.Obviously, along with the quantity of data entries is more and more, retrieval rate can be more and more slower, thereby cannot guarantee that user finds at a high speed the target information entry oneself needing exactly.
Summary of the invention
The invention provides a kind of media player and characters input method thereof, can retrieve target information entry at a high speed, exactly and intelligent degree is higher.

Embodiment
For making object of the present invention, technical scheme and advantage clearer, referring to the accompanying drawing embodiment that develops simultaneously, the present invention is described in more detail.
The embodiment of the present invention provides a kind of characters input method of media player, and its flow process as shown in Figure 1, specifically comprises:
Step 101: for multiple data entries of storing in described media player, set up corresponding relation the preservation of each character in the index mark of each data entries and affiliated index mark;
Step 102: receive the character of input, according to the corresponding relation of preserved character and index mark, obtain the index mark corresponding with the character of described input, and export the index mark obtaining;
Step 103: receive the selection instruction of input, in the index mark corresponding at the obtained character with described input, the index mark that selected described selection instruction is indicated.
It should be noted that, described index mark refers to the information word for identification information entry, for example: for a music file, this file generally includes filename, performance or sings polytype index mark such as musician, affiliated musical form of this music, in actual applications, the most common also the most frequently used index mark is filename, but it should be pointed out that method that the present invention shows can expand in the retrieval of the index mark to other types equally.For convenience of describing, the index mark of hereinafter mentioning is information bar destination name of the file, easily understands, and this narration only, for for example, does not represent the restriction to the invention process method.
Wherein, receive the character of input described in step 101, according to the corresponding relation of preserved character and index mark, the method that obtains the index mark corresponding with the character of described input specifically comprises:
Receive multiple characters of input, according to the corresponding relation of preserved character and index mark, obtain existing with described multiple characters the index mark of corresponding relation.
It should be noted that, a character can identify corresponding to the index of multiple data entries simultaneously, the index mark of the multiple data entries simultaneously corresponding with a character forms the set of an index mark, and the corresponding relation of setting up and preserving in described step 101 is the corresponding relation of each character and this set.Simultaneously, due to described step 101 have at every turn data entries add media player in time be all performed once (no matter whether to carry out character input, step 101 all needs to carry out), therefore for including the media player of some data entries, the each character comprising in the index mark of each data entries and the index mark of this data entries have all been set up corresponding relation, thereby have included the character of some---the corresponding relation of index mark set.Therefore, once add the data entries in described equipment to regard to certain, if the character comprising in the index of this data entries mark is the character of having set up corresponding relation, described step 101 is actual is the process that existing corresponding relation is upgraded, if and the character comprising in the index of described data entries mark has partly or entirely for still there is not the character of corresponding relation, these characters are needed to set up new corresponding relation.
For describing the difference of above-mentioned two situations in detail, be specifically described below by an example:
If certain less important index mark (for the sake of simplicity, the index mark of establishing is now this information bar destination name of the file) of adding the central data entries of media player to is " call ", below two kinds of described situations are discussed respectively:
1) if the index of existing data entries mark comprises in described media player: " call out, wake up, call out, shout, sky ", known according to narrating above, before described " call " adds this equipment to, the corresponding relation having existed should be:
The index mark set that character " is exhaled " comprises: " call out, call out ";
The index mark set that character " is named " comprises: " call out, shout ";
The index mark set that character " is called out " comprises: " waking up ";
The index mark set that character " is waken up " comprises: " waking up ";
The index mark set that character " is cried out " comprises: " call out, shout ";
Character " my god " index mark set comprise: " sky ";
The index mark set of character " sky " comprising: " sky ".
After described " call " adds this equipment to, the corresponding relation after execution step 101 should be:
The index mark set that character " is exhaled " comprises: " call out, call out, call ";
The index mark set that character " is named " comprises: " call out, shout ";
The index mark set that character " is called out " comprises: " wake up, call ";
The index mark set that character " is waken up " comprises: " waking up ";
The index mark set that character " is cried out " comprises: " call out, shout ";
Character " my god " index mark set comprise: " sky ";
The index mark of character " sky " is closed and is comprised: " sky ".
Visible, described step 101 is actual is the renewal to the set of the existing index that character " is exhaled " and existing character " is called out " mark---, in described two set, add a new corresponding relation " call " respectively.
2) if the index of existing data entries mark comprises in described media player: " shout, sky ", now to be added to the central data entries of equipment, the character comprising in its index mark is the character that does not still have corresponding relation, known according to narrating above, before described " call " adds this equipment to, the corresponding relation having existed should be:
The index mark set that character " is cried out " comprises: " shouting ";
The index mark set that character " is named " comprises: " shouting ";
Character " my god " index mark set comprise: " sky ";
The index mark set of character " sky " comprising: " sky ".
After described " call " adds this equipment to, the corresponding relation after execution step 101 should be:
The index mark set that character " is cried out " comprises: " shouting ";
The index mark set that character " is named " comprises: " shouting ";
Character " my god " index mark set comprise: " sky ";
The index mark set of character " sky " comprising: " sky ".
the index mark set that character " is exhaled " comprises: " call ";
the index mark set that character " is called out " comprises: " call ";
Visible, the corresponding relation of described step 101 is now newly-built two characters and data entries index mark thereof---, set up respectively that character " is exhaled " and character " is called out " and the set of index mark, and in this set, comprised respectively a corresponding relation " call ".
In addition, corresponding with the process in step 101, the method can further include:
Step 101a:
In the time that data entries is deleted from described media player, remove the corresponding relation that each character in the index mark of this data entries and this index identify.
Easily understand, between described step 101, step 101a and subsequent step 102～103, there is not strict sequencing, in fact response action when described foundation, preservation, renewal or the step of removing described corresponding relation are data entries change (being that data entries is saved in media player or deletes) from equipment, it is the angle from the workflow of whole method, described corresponding relation need to be first set up, the retrieving of subsequent step 102～103 could be carried out.Simultaneously, those skilled in the art also easily understand, in above-mentioned steps 101 and step 101a, set up, preserve, upgrade and remove the process of described corresponding relation, can be very easily by the operation of data link table, matrix or other data structure be realized in the time of actual realization, specifically be the known technology of person skilled, repeat no more herein.
Further, described in, obtain existing the method for the index mark of corresponding relation specifically to comprise with described multiple characters:
There is the index mark that all has corresponding relation with multiple characters of inputting if judge, using this index mark as existing the index of corresponding relation to identify with described multiple characters; If there is not the index mark that all has corresponding relation with inputted multiple characters in judgement, using with described multiple characters in partial character exist the index mark of corresponding relation as existing the index of corresponding relation to identify with described multiple characters.
Correspondingly, now, in step 102, the index mark that described output obtains specifically comprises:
According to exporting obtained index mark with the mode of the matching degree descending sort of described multiple characters, wherein, there is the index mark of corresponding relation with more multiple inputted characters, the matching degree of itself and described multiple characters is higher.
Easily understand, the matching degree of described index mark and the character of input can also further be expanded and be: front and back order and context relation between the each character in the character information of input, more approaching with front and back order and the context relation of respective symbols in index mark, matching degree is higher, otherwise matching degree is lower.The matching degree of mentioning is herein to search for the known technological means of those skilled in the art generally, does not modify and improve in application of the present invention, therefore no longer launches narration, specifically can consult related data.
For further retrieving clearly of the present invention, below by a concrete example, described step 101～103 are explained:
If the index of the data entries comprising in the media player mark title of data entries (in this example for) is respectively: gimmick, get started, enter, victory or defeat, transportation, write, write, writer, hand-written, transmission, carry, enter to the greatest extent my hand, helper, assistant, input, start with;
For saving length, the process of adding described 16 data entries to described equipment is herein omitted, also corresponding relation unrelated to the invention (for example data entries corresponding with character " pair ", " work ", " win " etc.) is omitted, now the corresponding relation of character and data entries comprises simultaneously:
The set of index that character " is write " mark comprises: write, write, writer, hand-written;
The index mark set of character " defeated " comprising: victory or defeat, transportation, transmission, conveying, input;
The index mark set of character " hand " comprising: gimmick, writer, hand-written, enter my hand, helper, assistant to the greatest extent;
The set of index that character " enters " mark comprises: get started, enter, enter to the greatest extent my hand, input.
Suppose now a data entries " handwriting input " to be added in described media player, step 101 will be set up the corresponding relation that the character that comprises in the index mark of this data entries and this data entries index identify, and corresponding relation now comprises:
Index that character " is write " mark set (being made as set A) comprising: write, write, writer, hand-written, handwriting input;
The index mark set (being made as set B) of character " defeated " comprising: victory or defeat, transportation, transmission, conveying, input, handwriting input;
The index mark set (being made as set C) of character " hand " comprising: gimmick, writer, hand-written, enter my hand, helper, assistant, handwriting input to the greatest extent;
Index that character " enters " mark set (being made as set D) comprising: get started, enter, enter to the greatest extent my hand, input, handwriting input.
If a) in step 102, the primary election character of input is " handwriting input ", for this primary election character, it comprises " hand ", " writing ", " defeated " and " entering " four characters, in index mark set due to described each character, all comprise " handwriting input " this entry (common factor of set A, B, C, D is " handwriting input "), therefore show that final result for retrieval is for " handwriting input ".
If b) user has forgotten the accurate title of described data entries " handwriting input ", only remember the partial content (such as " hand-written ") of this data entries title, in step 102, user inputs after " hand-written ", corresponding result for retrieval should be the common factor of set A and C, i.e. " hand-written, handwriting input, writer " (actual ordering is correspondingly determined by the algorithm of the matching degree of setting, and will not discuss herein); When user obtains after this result for retrieval, the result that generally will be retrieved is suggested and to remember what want retrieval should be " handwriting input ", thereby can correctly retrieve equally the index mark of the data entries needing.
Because the index mark of the data entries in media player is generally some specific phrases and phrase (such as song title, place name, Business Name etc. are all generally proprietary phrases), be not common common daily phrase and phrase, therefore this information retrieval method is specially adapted to be applied in the middle of media player, and can realize information inquiry fast and effectively.
Based on the above method, the present invention also provides a kind of media player simultaneously, and its composition structure as shown in Figure 2, specifically comprises: corresponding relation operational module 210 and retrieval module 220;
Wherein, corresponding relation operational module 210, for multiple data entries that described media player is stored, sets up respectively corresponding relation the preservation of each character of comprising in the index mark of each data entries and affiliated index mark;
Wherein, described corresponding relation operational module 210 comprises that corresponding relation sets up unit 211 and corresponding relation delete cells 212;
Described corresponding relation is set up unit 211, for multiple data entries that described media player is stored, sets up respectively corresponding relation the preservation of each character of comprising in the index mark of each data entries and affiliated index mark;
Described corresponding relation delete cells 212, in the time having data entries to delete from described media player, removes the corresponding relation that each character in the index mark of this data entries and this index identify.
Described retrieval module 220, comprises the first selected cell 221 and the second selected cell 222;
Described the first selected cell 221, for receiving multiple characters of input, according to the corresponding relation of preserved character and index mark, obtain existing with described multiple characters the index mark of corresponding relation, and the index that output obtains identifies;
Described the second selected cell 222, for receiving the selection instruction of input, in the index mark corresponding at the obtained character with described input, the index mark that selected selection instruction is indicated.
Meanwhile, described the first selected cell 221 further comprises: judgment sub-unit 223 and output subelement 224;
Described judgment sub-unit 223, for receiving multiple characters of input, judge according to the corresponding relation of preserved character and index mark, if there is the index mark that all has corresponding relation with multiple characters of inputting in judgement, using this index mark as existing the index of corresponding relation to identify with described multiple characters, otherwise, using with described multiple characters in partial character exist the index mark of corresponding relation as existing the index of corresponding relation to identify with described multiple characters;
Described output subelement 224, for according to exporting with the mode of the matching degree descending sort of described multiple characters the index mark that judgment sub-unit obtains, wherein, have the index mark of corresponding relation with more multiple inputted characters, the matching degree of itself and described multiple characters is higher.
From above-mentioned, the media player that the embodiment of the present invention provides and characters input method thereof, the corresponding relation identifying by setting up each character in the index mark of each data entries and affiliated index, thereby can in the time retrieving, needn't rely on the index mark initial character of the data entries to desired seek or the accurate memory of alphabet, and any one or more characters that the index that can utilize the data entries of desired seek comprises in identifying are retrieved---for example only remember the partial content of the index mark of the data entries of desired seek, while even retrieval the character of input put in order with the index mark of the data entries of desired seek in character sequence and inconsistent situation under, thereby still can successfully retrieve and obtain result for retrieval---character input and data entries retrieval are organically combined in the middle of a process, degree of intelligence and the ease for use of character input and retrieval are greatly improved, and then significantly improve character input and the speed of retrieval and the success ratio of retrieval.
Above-mentioned explanation is for data entries and retrieves the description of carrying out, in concrete application, retrieve the result obtaining according to data entries, different media players can also carry out further other application, for example, preferably, on the basis of described media player and characters input method thereof, carry out the application of television programme title or channel designation search for utilizing digital TV set-top box, the embodiment of the present invention also further provides a kind of television program search viewing method: first utilize described characters input method to carry out the search of channel designation or television programme title, rear line prompting search result, after the TV programme or channel of selecting from Search Results user to watch, the TV programme that storage user selects or the information of channel, and arrange user select TV programme or the watch time of channel, in the time arriving the watch time of described TV programme or channel, prompting user, thereby user can be facilitated, fast, punctual TV programme or the channel that need to watch watched.
