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 continuous development of integrated circuit technique, cost was but in continuous reduction when the processing power of integrated circuit (IC) chip constantly strengthened.Therefore, more and more technical embedded devices have appearred in the computing machine that conventional data is handled that carries out except traditional now, because advantage and the comparatively single-minded function and usage thereof of embedded device on cost obtained significant progress in recent years.
In the embedded device application, though continuous development along with software and hardware technology, the function of its processing power and man-machine interaction is improving constantly and perfect, but be limited by multiple reasons such as its cost, small product size size, construction cycle and market outlook, the size of the arithmetic capability of its process chip and storage space still is severely limited than multi-purpose computer usually.In this case, the application software of using in the embedded device, the comparatively pocket usually and function of volume is simplified relatively, thereby just has inconvenience when using.For example, current widely used on the market various handheld terminals and digital entertainment equipment (hereinafter being referred to as embedded device), as Mp3, Mp4 player, digital TV set-top box, mobile phone, handheld game machine, PDA(Personal Digital Assistant), Global Positioning System (GPS) (GPS) navigating instrument etc., all need through carrying out the character input under the scene of the information retrieval of being everlasting---such as in Mp3, Mp4, searching for audio-video document, in the GPS navigation instrument, search for the title in road, 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 the character input, obtain the character information formed by a character at least---promptly, preestablish character database, the user carries out the character input by modes such as phonetic, stroke combination, hand-written even phonetic entries, and embedded device will meet the candidate characters of initial conditions or character combination according to the priority of frequency of utilization to carry out descending sort and select for the user.The input method of partially embedded equipment also has associating input function, promptly after the user finishes last time character input and selectes candidate characters, all characters that can form character combination with described last time character in character database frequency of utilization according to this character combination is shown, with the input operation number of times of saving the user and improve input speed; In addition, also have the input method of partially embedded equipment can be dynamically character database to be upgraded according to user's input results, for example the user is in character database beyond existing phrase or the phrase, get up to import from being about to several character combinations, then system will add a new phrase or the phrase of this character combination as initial character in the described character combination in the middle of the described character database to; Afterwards, when this character occurs as initial character once more, will be with this character combination as a candidate item, with in the character database existing other be that the phrase or the phrase of initial character shows jointly as candidate entries with this character, select for the user.
Step B: utilize the character information of steps A input that target database is retrieved.Described target database is the address that adopts in order to distinguish character database, under different application scenarioss, it may represent different implications, such as: during as if retrieval music file in Mp3, described target database is meant the set that comprises all music file titles, if retrieval is during place name in the GPS navigation instrument, described target database then is meant the set of all geographical indication titles that comprise in the map datum bag, and if when watching TV when searching TV program title or channel designation, described target database then is meant the set of television programme title or the set of channel designation, because its concrete implication that comprises under concrete application scenarios is can be for known in those skilled in the art, so 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, and the retrieval that the index of the data entries in target database sign is word for word mated.That is, in target database, all data entries of the initial character coupling in the initial character of search index sign and the character information of described input; In all index signs that retrieval is come out, further retrieve all data entries of second character match in the character information of all second characters and described input again, constantly repeat this match retrieval process, up to match retrieval finished in all characters in the character information of described input, 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 carry out match retrieval, and when step B carried out match retrieval, the user can also further upgrade (for example continuing the new character of input) to character information; Or, can also be corresponding by Chinese character and its first letter of pinyin are carried out (for example " frequently " corresponding " p ", " frequency " correspondence " pl "), realize the fuzzy query function of Chinese data entries being retrieved by the input English character.To this, the various retrieval form of maturation and kind has been arranged in the prior art, give unnecessary details no longer one by one at this.
Though it is various informative to be applied to the mode of operation and the operation interface of the information retrieval in the embedded device in the 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 continuous enhancing of embedded device function and capacity improve constantly, content of preserving in the equipment and information quantity are also more and more, the user more and more is difficult to the title that complete sum is remembered all information exactly, the randomness and the randomness of carrying out information retrieval are increasing gradually, and this can cause the retrieval mode of prior art to occur variety of issue in actual applications:
At first, increase along with data entries quantity, the user is difficult to remember the initial character of all data entries, the detection that existing retrieval technique then must depend on initial character could realize, and the user forgets the title of complete target information clauses and subclauses sometimes, but might remember some fragments in its title, existing retrieval mode then can't 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---promptly by user inputs character information, in all data entries, carry out match retrieval then.Obviously, along with the quantity of data entries is more and more, retrieval rate can be more and more slower, thereby can't guarantee that the user finds the target information clauses and subclauses that oneself need at a high speed exactly.

Embodiment
For making purpose of the present invention, technical scheme and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in more detail.
The embodiment of the invention provides a kind of characters input method of media player, and its flow process specifically comprises as shown in Figure 1:
Step 101:, set up the corresponding relation and the preservation of each character and affiliated index sign in the index sign of each data entries for a plurality of data entries of storing in the described media player;
Step 102: receive the character of input, according to the corresponding relation of character of being preserved and index sign, obtain the index sign corresponding, and export resulting index sign with the character of described input;
Step 103: receive the selection instruction of input, in the corresponding index sign of character resulting and described input, the index sign that selected described selection instruction is indicated.
Need to prove, described index sign is meant and is used for the information word of identification information clauses and subclauses, for example: for a music file, this document generally includes filename, performance or sings polytype index sign such as the musician of this music, affiliated musical form, in actual applications, the most common also the most frequently used index sign is a filename, but should be pointed out that method that the present invention shows can expand in the retrieval to the index sign of other types equally.Describe for convenient, the index sign of hereinafter mentioning is the information bar destination name of the file, understands easily, and this narration only for for example, is not represented the qualification to the invention process method.
Wherein, receive the character of input described in the step 101, according to the corresponding relation of character of being preserved and index sign, the method that obtains the index sign corresponding with the character of described input specifically comprises:
Receive a plurality of characters of input,, obtain existing the index sign of corresponding relation with described a plurality of characters according to the corresponding relation of character of being preserved and index sign.
Need to prove, character can be simultaneously corresponding to the index sign of a plurality of data entries, then the index sign with the simultaneously corresponding a plurality of data entries of character constitutes the set of an index sign, and the corresponding relation of setting up in the described step 101 and preserving is the corresponding relation of each character and this set.Simultaneously, because all being performed once at every turn, described step 101 (no matter whether carries out the character input when having data entries to add in the media player, step 101 all needs to carry out), therefore for the media player that includes some data entries, each character that comprises in the index sign of each data entries and the index sign of this data entries have all been set up corresponding relation, thereby have included the character of some---the corresponding relation of index sign set.Therefore, once add data entries in the described equipment to regard to certain, if the character that comprises in the index of this data entries sign is the character of having set up corresponding relation, then described step 101 is actual to be the process that existing corresponding relation is upgraded, if and the character that comprises in the index of the described data entries sign has partly or entirely for still there not being the character of corresponding relation, these characters are then needed to set up new corresponding relation.
For describing the difference of above-mentioned two kinds of situations in detail, be specifically described below by an example:
If certain less important index sign (for the sake of simplicity, the index sign of establishing this moment is this information bar destination name of the file) of adding the central data entries of media player to is " call ", below described two kinds of situations are discussed respectively:
1) if the index sign of existing information clauses and subclauses comprises in the described media player: " call out, wake up, call out, shout, sky ", then according to the preamble narration as can be known, before described " call " added this equipment to, the corresponding relation that has existed should be:
The index sign set that character " is exhaled " comprises: " call out, call out ";
The index sign set that character " is named " comprises: " call out, shout ";
The index sign set that character " is called out " comprises: " waking up ";
The index sign set that character " is waken up " comprises: " waking up ";
The index sign set that character " is cried out " comprises: " call out, shout ";
Character " my god " index sign set comprise: " sky ";
The index sign set of character " sky " comprising: " sky ".
After described " call " added this equipment to, the corresponding relation after the execution in step 101 then should be:
The set of index that character " is exhaled " sign comprises: " call out, call out,
Call";
The index sign set that character " is named " comprises: " call out, shout ";
The index sign set that character " is called out " comprises: " wake up,
Call";
The index sign set that character " is waken up " comprises: " waking up ";
The index sign set that character " is cried out " comprises: " call out, shout ";
Character " my god " index sign set comprise: " sky ";
The index sign of character " sky " is closed and is comprised: " sky ".
As seen, described step 101 is actual is the renewal that the existing index that character " is exhaled " and existing character " is called out " sign is gathered---promptly, in described two set, added a new corresponding relation " call " respectively.
2) if the index sign of existing information clauses and subclauses comprises in the described media player: " shout, sky ", promptly to be added to the central data entries of equipment this moment, the character that comprises in its index sign is the character that does not still have corresponding relation, according to the preamble narration as can be known, before described " call " added this equipment to, the corresponding relation that has existed should be:
The index sign set that character " is cried out " comprises: " shouting ";
The index sign set that character " is named " comprises: " shouting ";
Character " my god " index sign set comprise: " sky ";
The index sign set of character " sky " comprising: " sky ".
After described " call " added this equipment to, the corresponding relation after the execution in step 101 then should be:
The index sign set that character " is cried out " comprises: " shouting ";
The index sign set that character " is named " comprises: " shouting ";
Character " my god " index sign set comprise: " sky ";
The index sign set of character " sky " comprising: " sky ".
The index sign set that character " is exhaled " comprises: " call ";
The index sign set that character " is called out " comprises: " call ";
As seen, the corresponding relation of described step 101 this moment is newly-built then two characters and data entries index sign thereof---promptly, set up respectively that character " is exhaled " and character " is called out " and the set of index sign, and comprised a corresponding relation " call " in this set respectively.
In addition, corresponding with the process in the step 101, this method can further include:
Step 101a:
When data entries is deleted, remove the corresponding relation that each character and this index in the index sign of this data entries identify from described media player.
Understand easily, there is not strict sequencing between described step 101, step 101a and the subsequent step 102～103, response action when in fact described foundation, preservation, renewal or the step of removing described corresponding relation are data entries and change (be data entries be saved in media player or the slave unit delete), it is angle from the workflow of entire method, described corresponding relation need be set up earlier, the retrieving of subsequent step 102～103 could be carried out.Simultaneously, those skilled in the art also understand easily, set up, preserve, upgrade and remove the process of described corresponding relation among above-mentioned steps 101 and the step 101a, when realizing, reality can realize by operation very easily data chained list, matrix or other data structure, specifically be the known technology of person skilled, repeat no more herein.
Further, described obtaining exists the method for the index sign of corresponding relation specifically to comprise with described a plurality of characters:
There is the index sign that all has corresponding relation with a plurality of characters of being imported as if judgement, then identifies as existing the index of corresponding relation to identify with described a plurality of characters with this index; If judge not have the index sign that does not all have corresponding relation with a plurality of characters of being imported, then with described a plurality of characters in the part character exist the index sign of corresponding relation as existing the index of corresponding relation to identify with described a plurality of characters.
Correspondingly, at this moment, in the step 102, the resulting index sign of described output specifically comprises:
According to exporting resulting index sign with the mode of the matching degree descending sort of described a plurality of characters, wherein, there is the index sign of corresponding relation with a plurality of more characters of importing, the matching degree of itself and described a plurality of characters is high more.
Understand easily, the matching degree of the character of described index sign and input can also further be expanded and be: front and back order and context relation between each character in the character information of input, approaching more with the front and back order and the context relation of respective symbols in the index sign, then matching degree is high more, otherwise then matching degree is low more.The matching degree of mentioning herein is to search for the known technological means of those skilled in the art generally, does not make amendment in the application of the present invention and improves, and therefore no longer launches narration, specifically can consult related data.
For further clear and definite retrieving of the present invention, below by a concrete example to described step 101～103 explanation that makes an explanation:
If the index of the data entries that comprises in media player sign (be the title of data entries in this example) is respectively: gimmick, cross the threshold, enter, victory or defeat, transportation, write, write, writer, hand-written, transmission, conveying, to the greatest extent go into my hand, helper, assistant, import, start with;
For saving length, the process of adding described 16 data entries to described equipment is omitted herein, also will omit simultaneously, comprise in the corresponding relation of character and data entries at this moment with the corresponding relation (for example with corresponding data entries such as character " pair ", " work ", " wins ") that the present invention has nothing to do:
The set of index that character " is write " sign comprises: write, write, writer, hand-written;
The index sign set that character " is failed " comprises: victory or defeat, transportation, transmission, conveying, input;
The set of the index of character " hand " sign comprises: gimmick, writer, hand-written, go into my hand, helper, assistant to the greatest extent;
The set of index that character " is gone into " sign comprises: cross the threshold, enter, go into to the greatest extent my hand, input.
Suppose this moment a data entries " handwriting input " to be added in the described media player, then step 101 will be set up the corresponding relation of the character that comprises in the index sign of this data entries and this data entries index sign, comprises in the corresponding relation at this moment:
Index that character " is write " sign set (being made as set A) comprising: write, write, writer, hand-written, handwriting input;
The index sign set (being made as set B) that character " is failed " comprising: victory or defeat, transportation, transmission, conveying, input, handwriting input;
The index of character " hand " sign set (being made as set C) comprising: gimmick, writer, hand-written, go into my hand, helper, assistant, handwriting input to the greatest extent;
Index that character " is gone into " sign set (being made as set D) comprising: cross the threshold, enter, go into to the greatest extent my hand, input, handwriting input.
A) if the primary election character of input is " handwriting input " in the step 102, then for this primary election character, it comprises " hand ", " writing ", " failing " and " going into " four characters, owing to all comprise " handwriting input " these clauses and subclauses (common factor of set A, B, C, D is " handwriting input ") in the set of the index of described each character sign, therefore draw final result for retrieval and be " handwriting input ".
B) if the 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, after then the user imports " hand-written " in the step 102, corresponding retrieval results should be the common factor of set A and C, i.e. " hand-written, handwriting input, writer " (actual ordering correspondingly by the algorithm decision of the matching degree of setting, will not be discussed herein); After the user obtained this result for retrieval, the result that generally will be retrieved was suggested and to remember what want to retrieve should be " handwriting input ", thereby can correctly retrieve the index sign of the data entries that needs equally.
Because the index of the data entries in media player sign is generally some specific phrases and phrase (generally all is proprietary phrase such as song title, place name, Business Name etc.), be not common common daily phrase and phrase, therefore this information retrieval method is specially adapted to be applied in the middle of the 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 it forms structure as shown in Figure 2, specifically comprises: corresponding relation operational module 210 and retrieval module 220;
Wherein, corresponding relation operational module 210 is used for a plurality of data entries that described media player is stored, sets up the corresponding relation and the preservation of each character of comprising in the index sign of each data entries and affiliated index sign respectively;
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, is used for a plurality of data entries that described media player is stored, sets up the corresponding relation and the preservation of each character of comprising in the index sign of each data entries and affiliated index sign respectively;
Described corresponding relation delete cells 212 is used for whenever data entries being arranged when described media player is deleted, and removes the corresponding relation that each character and this index in the index sign of this data entries identify.
Described retrieval module 220 comprises first selected cell 221 and second selected cell 222;
Described first selected cell 221 is used to receive a plurality of characters of input, according to the corresponding relation of character of being preserved and index sign, obtains existing with described a plurality of characters the index sign of corresponding relation, and exports resulting index sign;
Described second selected cell 222 is used to receive the selection instruction of input, in the corresponding index sign of character resulting and described input, and the index sign that selected selection instruction is indicated.
Simultaneously, described first selected cell 221 further comprises: judgment sub-unit 223 and output subelement 224;
Described judgment sub-unit 223, be used to receive a plurality of characters of input, corresponding relation according to character of being preserved and index sign is judged, there is the index sign that all has corresponding relation with a plurality of characters of being imported if judge, identify as existing the index of corresponding relation to identify with this index with described a plurality of characters, otherwise, with described a plurality of characters in the part character exist the index sign of corresponding relation as existing the index of corresponding relation to identify with described a plurality of characters;
Described output subelement 224, be used for according to exporting the index sign that judgment sub-unit obtains with the mode of the matching degree descending sort of described a plurality of characters, wherein, have the index sign of corresponding relation with a plurality of more characters of importing, the matching degree of itself and described a plurality of characters is high more.
By as seen above-mentioned, media player that the embodiment of the invention provides and characters input method thereof, corresponding relation by each character in the index sign of setting up each data entries and affiliated index sign, thereby can when retrieving, needn't rely on the index sign initial character of the data entries of desired seek or the accurate memory of alphabet, and can utilize any one or a plurality of character that comprise in the index sign of data entries of desired seek to retrieve---for example only remember the partial content of index sign of the data entries of desired seek, even under the character sequence and inconsistent situation in the index sign with the data entries of desired seek of putting in order of the character of when retrieval input, thereby still can successfully retrieve and obtain result for retrieval---character input and data entries retrieval organically are combined in the middle of the process, improve the degree of intelligence and the ease for use of character input and retrieval greatly, and then significantly improved character input and the speed of retrieval and the success ratio of retrieval.
Above-mentioned explanation is the description that retrieval is carried out at data entries, in concrete application, the result that retrieval obtains 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 invention also further provides a kind of television program search viewing method: at first utilize described characters input method to carry out the search of channel designation or television programme title, afterwards to the user prompt Search Results, after TV programme or channel that the user selects to watch from Search Results, the TV programme that the storage user selects or the information of channel, and watching the time of TV programme that the user selects or channel be set, when arrive described TV programme or channel watch the time time, the prompting user, thus the user can be made things convenient for, fast, punctual TV programme or the channel that to watch of watching.
