Embodiment Construction

[0015] The storage medium in the embodiment of the present invention is used to store music data, and the compressed format of the music data is MP3. The music data in this embodiment has an ID3 format field, and the playback device can synchronously display the lyrics of the music data on the display device according to the ID3 format field, wherein the ID3 format field includes a data segment and a synchronization segment.

[0016] Firstly, the data section is described. The data section mainly defines the text mode of the text data in the music data, such as the displayed language form and the playback text mode, etc. A piece of music data only needs to define one data section. The data section includes the following fields: frame identification field (Frame ID), length field (Size), flag field (Flags), text form field (Text Type), mode field (Lyric Mode) , language form field (Language Type), reserved field (Reserved) and mobile time field (Time shift), please refer to Tab...

Abstract

The invention relates to a data synchronization method, applicable to music playback program, used for playing back music data and synchronously displaying words of song, in which the the music data is MP3 format, and in the MP3 format it has ID3 format column position. Said data synchronization method includes the following steps: firstly, fetching music data, and in ID3 format column position of said music data containing at least one literal data and time flag data for representing correspondent time of literal data in the music data, then according to the literal data and correspondent time flag data producing index mark table, said index mark table is used for representing display time of literal data when the music data is played back, finally music playback program can be used for playing back music data,and according to index mark table synchronously displaying literal data on display device.

Description

technical field [0001] The invention relates to a data synchronization method applicable to a music playing program, used for playing music data in MP3 format and synchronously displaying lyrics. In particular, it relates to a data synchronization method, which is applicable to a music player program for playing music data in MP3 format with an ID3 format field. Background technique [0002] MP3 (MPEG-1 Layer-3) is one of the commonly used music formats at present. The basic principle of MP3 is to perform appropriate compression according to the sensitivity of the human ear to audio distortion, and filter out the signal components that the human ear cannot hear. Encoded into ".mp3" files. Because MP3 can be compressed to 12 times. That is to say, an ordinary disc compressed in MP3 format can hold 12 CDs of music, and then through an MP3 player, it can be played continuously for several hours without affecting the sound quality. Therefore, MP3 format files are widely used,...
