Please with reference 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, treat that played songs is " sea, native place ", at the store path of portable terminal
Store the audio file " sea, native place .mp3 " of tape song down, treat that the played songs audio file can be multiple file formats such as mp3, wma, rm.
Table 1LRC form lyrics file content example
Confirm 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, confirm the coded format of file " sea, native place .lrc "; The concrete grammar of confirming 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 kinds of situation, show that then file " sea, native place .lrc " is the ANSI coded format.
Secondly, the application programming interfaces (API, Application ProgramInterface) that provide through portable terminal manufacturer are confirmed 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 read the character in the file " sea; native place .lrc " one by one; The character that reads for " when [", with in the file " sea, native place .lrc " with this " [" character is starting point, with this " after [" character 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: confirm among the character string str that " each character in the substring between [" and ": " character is whether in numeral 0～9 scope; When the coded format of for example supporting at the terminal is ANSI; Judge that " each byte content is whether in numeral 0～9 corresponding ANSI encodes 30～39 scopes, if explain that this label is a time tag in the substring between [" and ": " character; The temporal information that label is comprised; Promptly the content between " [" and "] " is stored in the time_array array as an array element, and the lyrics that time tag is corresponding are kept in the lyric_array array; Otherwise, explain 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 through 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 " substring between [" and ": " symbol is as the content of time_buffer [0] among the character string str; With ": " and "] " between substring as the content of time_buffer [1]; With the 1st time tag of the 6th row in the table 1 [01:38.29] is example, with 01 content as time_buffer [0], with 38.29 contents as time_buffer [1];
Then; According to the content of time_buffer [0] and time_buffer [1], confirm time_itemvalue, with time_itemvalue as array element; Be stored in the time_array array; Wherein, time_itemvalue=atoc (time_buffer [1]) * 1000+atoc (time_buffer [0]) * 60000=98290 is about to temporal information and is 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; The lyric characters " as a child mother said me " that this time tag is corresponding is stored in the lyric_array array as lyric_array [0]; 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] is 0-0, and display [0] is 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 equally this time tag is comprised is stored in the time_array array as an array element, and the lyric_array array element that this element is corresponding is a null character string.
For example; Current reproduction time in song is 01:39.00; In the time_array array after ordering between element time_array [0]=01:38.29 and element time_array [the 1]=01:43.06 time; According to the corresponding relation between time_array that preserves among the display [0] and the lyric_array [0], from lyric_array, take out the corresponding lyrics " as a child mother said me " of time_array [0]=01:38.29 as literal to be shown.
In the time_array array of current reproduction time after ordering between adjacent two elements, and the lyrics that previous element is corresponding in adjacent two elements before the current time arrives a back element, do not show the lyrics when be sky.
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; When current reproduction time is identical with an element time_array [n] in the time_array array; Corresponding relation n-m according to the time_array array element of preserving among the display and lyric_array array between original obtains the corresponding song literal lyric_array [m] of this element time_array [n], and the time difference of definite time_array [n] and time_array [n+1]; According to character quantity that comprises among the song literal lyric_array [m] and the time difference of determining, confirm to show the required time of each character in the song literal.For example; At current reproduction time is 01:39.00; In the time_array array after ordering between element time_array [0]=01:38.29 and element time_array [the 1]=01:43.06 time; Confirm the time difference 4.77s between time_array [0] and the time_array [1]; Then according to the character quantity of corresponding lyric_array [0]=" as a child mother said me " of time_array [0]; Confirm to show required ≈ 0.6s average time 4.77/8 of each character that when the current time was between time_array [0]=01:38.29 and time_array [the 1]=01:43.06, (about every 0.6s demonstration character late) showed each character among the lyric_array [0] evenly.
In addition; In order to obtain better lyrics display effect, provide song relevant background information to the user, in step 203; Except the lyric characters that time tag is corresponding as the element in the lyric_array array; Can also be when judging label and be identification (RFID) tag, the word content after ": " in the identification (RFID) tag is as the array element in the lyric_array array, follow-up in step 206; In the time of before first element time_array [0]=01:38.29 in the time_array array of the current reproduction time of song after ordering, the lyric_array array element that each identification (RFID) tag is corresponding shows as the lyrics to be shown evenly.
In step 203, adopt 3 arrays to come the corresponding relation of difference information memory time, the lyrics and 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 the content of the 14th row in the table 1 needs 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 the scheme of above-mentioned employing time_array array, lyric_array array and display array difference information memory time, 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; Can the function of time_array array and display array be merged; The data structure that is each element in the time_array array be a structure (time, lyric_array_index) rather than numeral, this structure is made up of index value two parts of element in temporal information and the corresponding lyric_array array; For example to first time tag [01:38.29]; 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 through the comparison played songs and the time_array array after the ordering in each element structure body is confirmed 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.
The scheme of the playing songs on mobile terminal that the embodiment of the invention provides exists in portable terminal when treating the corresponding LRC form lyrics file of played songs, and the temporal information that each time tag in the LRC form lyrics file is comprised is as array element; Be stored in first array; And the lyrics that each time tag is corresponding are stored in second array, according to the time order and function order as array element; Element in first array sorts; When played songs,, from second array, obtain in said first array corresponding lyrics of previous element in adjacent two elements in first array of current reproduction time after ordering between adjacent two elements the time; And the lyrics of demonstration acquisition; Realized portable terminal in played songs, can synchronously show the corresponding lyrics of voice in the song of current broadcast, can not synchronously show the problem of the lyrics when having avoided through existing playing songs on mobile terminal.
