Be explained in detail to the main realization principle of embodiment of the invention technical scheme, embodiment and to the beneficial effect that should be able to reach below in conjunction with each accompanying drawing.
As shown in Figure 1, the main realization principle process of the embodiment of the invention is as follows:
To introduce an embodiment in detail and come the main realization principle of the inventive method is explained in detail and illustrates according to foregoing invention principle of the present invention below.
Please refer to accompanying drawing 2, the flow chart of the playing songs on mobile terminal scheme that proposes for the embodiment of the invention.
In the present embodiment, song to be played is " sea, native place ", at the store path of portable terminal
SongsStore the strip sowing bent audio file " sea, native place .mp3 " of singing down, song audio files to be played can be multiple file formats such as mp3, wma, rm.
Table 1LRC form lyrics file content example
Determine whether the concrete grammar consistent with the coded format of current mobile terminal support is for the coded format of file " sea, native place .lrc ":
At first, determine the coded format in file " sea; native place .lrc ", the concrete grammar of determining the document No. form is more, for example calls existing function interface, perhaps also can adopt following short-cut method: the content that reads preceding 3 bytes of file " sea; native place .lrc ", if the content of preceding 3 bytes is followed successively by 0xEF, 0xBB, 0xBF, show that then file " sea, native place .lrc " is the UTF-8 coded format; If the content of preceding 2 bytes in preceding 3 bytes is followed successively by 0xFF, 0xFE, show that then file " sea, native place .lrc " is the unicode coded format; If the content of preceding 2 bytes in preceding 3 bytes is followed successively by 0xFE, 0xFF, show that then file " sea, native place .lrc " is a unicode_big endian coded format; If the content of preceding 3 bytes is not above-mentioned several situation, show that then file " sea, native place .lrc " is the ANSI coded format.
Secondly, the application programming interfaces (API, Application ProgramInterface) that provide by portable terminal manufacturer are determined the coded format that portable terminal is supported;
Then, whether the coded format of comparison document " sea, native place .lrc " is consistent with the coded format of current mobile terminal support.
Wherein, the concrete grammar that obtains label is for reading the character in the file " sea; native place .lrc " one by one, at the character that reads for " when [", with in the file " sea, native place .lrc " with this " [" character is starting point, with this " [" character after immediate "] " character character string str that is terminal point as label.
Judge that label is that time tag still is that the method for identification (RFID) tag is: determine among the character string str that " each character in the substring between [" and ": " character is whether in numeral 0～9 scope, for example when the coded format of terminal support is ANSI, judge that " each byte content is whether in the ANSI of numeral 0～9 correspondence encodes 30～39 scopes in the substring between [" and ": " character, if, illustrate that this label is a time tag, the temporal information that label is comprised, promptly the content between " [" and "] " is as an array element, be stored in the time_array array, and the lyrics of time tag correspondence are kept in the lyric_array array; Otherwise, illustrate that this label is an identification (RFID) tag.
Sort for the ease of follow-up array element to the time_array array, can be when judging label and be time tag, the temporal information that will comprise is converted into the millisecond value by quantizing after, will changes the millisecond value that obtains again and deposit among the time_array, the detailed process that quantizes is:
At first, with among the character string str " substring between [" and ": " symbol is as time_buffer[0] content, with ": " and "] " between substring as time_buffer[1] content, with the 1st time tag of the 6th row in the table 1 [01:38.29] is example, with 01 as time_buffer[0] content, with 38.29 as time_buffer[1] content;
Then, according to time_buffer[0] and time_buffer[1] content, determine time_itemvalue, with time_itemvalue as array element, be stored in the time_array array, wherein, time_itemvalue=atoc (time_buffer[1]) and * 1000+atoc (time_buffer[0]) * 60000=98290, be about to temporal information and be converted into the millisecond value.
In the present embodiment, the temporal information 98290 that above-mentioned first time tag [01:38.29] after quantizing is comprised is as time_array[0], be stored in the time_array array, with the lyric characters " as a child mother said me " of this time tag correspondence as lyric_array[0], be stored in the lyric_array array; If represent in the time_array array that with 0-0 there is corresponding relation in the 1st element in the 1st element and the lyric_array array, then display[0] be 0-0, with display[0] be stored in the display array.
For the corresponding lyrics is empty time tag, for example in the table 1 the 10th the row time tag, the temporal information that this time tag is comprised is stored in the time_array array as an array element equally, and the lyric_array array element of this element correspondence is a null character string.
For example, current reproduction time in song is 01:39.00, between the ordering after the time_array array in element time_array[0]=01:38.29 and element time_array[1]=01:43.06 between the time, according to the time_array[0 that preserves among the display] and lyric_array[0] between corresponding relation, from lyric_array, take out time_array[0]=lyrics " as a child mother said me " of 01:38.29 correspondence are as literal to be shown.
In the time_array array of current reproduction time after ordering between adjacent two elements, and when the lyrics of previous element correspondence be sky in adjacent two elements, before the current time arrives a back element, do not show the lyrics.
In order to obtain to be similar to the display effect that word for word occurs the lyrics among the OK a karaoke club ok, in step 206, an element time_array[n in current reproduction time and time_array array] when identical, corresponding relation n-m according to the time_array array element of preserving among the display and lyric_array array between original, obtain this element time_array[n] corresponding song literal lyric_array[m], and definite time_array[n] and time_array[n+1] time difference, according to song literal lyric_array[m] in the character quantity that comprises and time difference of determining, determine to show the required time of each character in the song literal.For example, at current reproduction time is 01:39.00, between the ordering after the time_array array in element time_array[0]=01:38.29 and element time_array[1]=01:43.06 between the time, determine time_array[0] and time_array[1] between time difference 4.77s, then according to time_array[0] corresponding lyric_array[0]=character quantity of " as a child mother said me ", determine to show required ≈ 0.6s average time 4.77/8 of each character, be in time_array[0 in the current time]=01:38.29 and time_array[1]=01:43.06 between the time, (about every 0.6s show character late) is with lyric_array[0 evenly] in each character show.
In addition, in order to obtain better lyrics display effect, provide song relevant background information to the user, in step 203, except with the lyric characters of time tag correspondence as the element in the lyric_array array, can also be when judging label and be identification (RFID) tag, with the word content after ": " in the identification (RFID) tag as the array element in the lyric_array array, follow-up in step 206, at first element time_array[0 in the time_array array of the current reproduction time of song after ordering]=01:38.29 before the time, the lyric_array array element of each identification (RFID) tag correspondence is shown evenly as the lyrics to be shown.
In step 203, adopt 3 arrays to come difference information memory time, the lyrics, and the corresponding relation of the temporal information and the lyrics, the advantage of doing like this is to save a large amount of memory spaces, for example for the repeated lyrics in songs playing process, only need song literal of storage to get final product, for example in the table 1 the 14th the row content, need to preserve 3 time_array array element time_array[5]=01:01.51, time_array[8]=02:16.35, time_array[11]=02:35.97,1 lyric_array array element lyric_array[5]=" sea, sea ", in the display array, preserve 3 corresponding relation display[5]=5-5, display[6]=8-5, display[7]=11-5, i.e. 3 corresponding same lyric_array array elements of time_array array element.
Except above-mentioned employing time_array array, lyric_array array and display array difference information memory time, outside the scheme of the lyrics and the corresponding relation between the two, in order to simplify processing procedure, other similar schemes can also be arranged, for example in step 203, the function of time_array array and display array can be merged, the data structure that is each element in the time_array array is a structure (time, lyric_array_index) rather than the numeral, this structure is made up of index value two parts of element in the lyric_array array of temporal information and correspondence, for example at first time tag [01:38.29], with array element (01:38.29,0) is kept in the time_array array, in step 205, sequencing according to first numerical value in each element structure body in the time_array array sorts to the element in the time_array array; In step 206, first numerical value in current reproduction time during by the comparison played songs and the time_array array after the ordering in each element structure body is determined the lyrics to be shown, in the time_array array of current reproduction time after ordering between adjacent two elements the time, with the element among the lyric_array that is index value with second numerical value in the previous element structure body in above-mentioned adjacent two elements in the lyric_array array as the lyrics to be shown.
