Problems solved by technology

However, due to the small size of the LCD screen of the portable MP3 player, it is impossible to display all the lyrics at the same time, so the lyrics must be displayed line by line in a synchronous manner
[0005] At present, such problems can be solved by allowing the user to edit the synchronized lyrics file by using an editing tool before the lyrics are downloaded to the portable MP3 player. However, the method of editing and storing the lyrics time is often not based on absolute time. And often take the number of sound frames (Frame) in the MP3 format, or other time formats similar to the MPEG specification as the unit. , when the integrated circuit must provide decoding, and when the MP3 file is recompressed or the bit rate (Bit Rate) is recompressed or the bit rate (Bit Rate) is changed with the number of MP3 sound frames (Frame), or other time formats, the synchronized lyrics are often would have to be remade, which could be quite a project

Embodiment Construction

[0021] At present, the mainstream specification of text data (such as: song title, lyrics, time and version, etc.) used for portable MP3 players is ID3, which can combine text data with audio data to become MP3 files. Now the common ID3 format is mostly its second or third version.

[0022] Referring to FIG. 1 , the ID3 format of the second version first lists the ID3 character string at the top of the format, and it occupies 3 bytes (Bytes) in total. Secondly, the second version field (V2) occupies 2 bits, the flag field occupies 1 bit, and the ID3 size field occupies 4 bits, so the header occupies 10 bits. And each tag field occupies 3 bits, and the tag size field has 3 bits, and thereafter, data field bits are attached. That is, the first tag field is followed by the first tag size field, followed by the first data field, and the second tag field is followed by the second tag size field, followed by the second data field, until the Nth The volume label field is followed b...

Abstract

This invention relates to a method for synchronously playing MP3 audio data and character data and its player, in which, said method includes the following steps: 1, pre-setting character data based on the being player ID3 format audio data, 2, said character data include: a lyric line digital section, a character attribute flag section, newline field of the lyrics of each line, a time length field, a segment field and lyric field, 3, said character data are stored in the ID3 character display format, 4, playing audio data and displaying lyrics in the character data when the playing time reaches to a specific time point, which is taken as the time length recorded by the character data.

Description

1. Technical field [0001] The invention relates to a method for synchronously playing MP3 audio data and character data and a player thereof. 2. Background technology [0002] At present, the digital music player products with MP3 as the mainstream digital music specification have completely diversified their forms. Moreover, portable MP3 players are favored by consumers for their stylish and dazzling appearance, small and light shape, diverse functions and characteristics that fully meet the new life in the Internet age. [0003] With the development of MP3 technology, there have been many software products that help users manage the functions of portable MP3 players. For many MP3 users, the function of synchronously displaying lyrics gives users considerable convenience. At the same time, you can also browse its lyrics and sing along with the played songs. This is a function that most music lovers expect, and it is also an important development direction of portable MP3 p...
