Abstract

A method of displaying text corresponding to an audio file on an audio player includes selecting a first audio file and loading a first text file corresponding to the first audio file. A character set file is generated and contains a list only those characters included in all text files stored in the audio player. The method further includes calculating a rate at which text is displayed on a display device electrically coupled to the audio player according to a predetermined relationship between a duration of the first audio file and a size of the first text file. Next, texts stored in the first text file are displayed on the display device at the calculated rate while simultaneously outputting audio signals decoded from the first audio file.

Claims

1. A method of displaying text corresponding to an audio file on an audio player, the method comprising:

selecting a first audio file;

loading a first text file corresponding to the first audio file;

generating a character set file, the character set file containing a list only those characters included in all text files stored in the audio player;

calculating a rate at which text is displayed on a display device electrically coupled to the audio player according to a predetermined relationship between a duration of the first audio file and a size of the first text file; and

displaying texts stored in the first text file on the display device at the calculated rate while simultaneously outputting audio signals decoded from the first audio file.

2. The method of claim 1 further comprising reading a first linking file and locating the first text file and the first audio file according to linking identifiers stored in the first linking file.

3. The method of claim 1 further comprising utilizing a first image file as a background image when text from the corresponding first text file is displayed on the display device.

4. The method of claim 1 wherein the predetermined relationship for calculating the rate at which text is displayed on the display device satisfies the equation F=N/T, where F represents a moving frequency at which text is displayed on the display device, N represents a quantity of text stored in the first text file, and T represents the duration of the first audio file.

5. The method of claim 4 further comprising selecting a calculation mode of the audio player, wherein the quantity of text N is selected from a group consisting of N_C, N_W, N_S, and N_p according to the selected calculation mode, wherein N_C represents a number of characters in the first text file, N_W represents a number of words in the first text file, N_S represents a number of sentences in the first text file, and N_P represents a number of paragraphs in the first text file.

6. The method of claim 1 further comprising providing input buttons for scrolling through the text displayed on the display device.

7. The method of claim 1 further comprising providing input buttons for changing the rate at which text is displayed on the display device.

8. The method of claim 1 further comprising transferring the first audio file and the first text file to the audio player from a host device.

9. The method of claim 1 wherein providing the character set file further comprises assigning a unique numerical code to each character contained in the character set file.

10. The method of claim 9 wherein displaying texts stored in the first text file on the display device comprises reading a plurality of numerical codes from the first text file, reading the characters corresponding to the numerical codes from the character set file, and displaying the characters on the display device.

11. A method of displaying text corresponding to an audio file on an audio player, the method comprising:

selecting a first audio file;

loading a first text file corresponding to the first audio file;

calculating a rate at which text is displayed on a display device electrically coupled to the audio player according to the equation F=N/T, where F represents a moving frequency at which text is displayed on the display device, N represents a total quantity of text stored in the first text file, and T represents the total duration of the first audio file; and

displaying texts stored in the first text file on the display device at the calculated rate while simultaneously outputting audio signals decoded from the first audio file.

12. The method of claim 11 further comprising selecting a calculation mode of the audio player, wherein the quantity of text N is selected from a group consisting of N_C, N_W, N_S, and N_P according to the selected calculation mode, wherein N_C represents a number of characters in the first text file, N_W represents a number of words in the first text file, N_S represents a number of sentences in the first text file, and N_P represents a number of paragraphs in the first text file.

13. A method of displaying text corresponding to an audio file on an audio player, the method comprising:

selecting a first audio file;

loading a first text file corresponding to the first audio file;

calculating a rate at which text is displayed on a display device electrically coupled to the audio player according to the equation F=N/T, where F represents a moving frequency at which text is displayed on the display device, N represents a quantity of text stored in the first text file, and T represents the duration of the first audio file, wherein the quantity of text N is selected from a group consisting of N_C, N_S, and N_P according to the selected calculation mode, wherein N_C represents a number of characters in the first text file, N_S represents a number of sentences in the first text file, and N_P represents a number of paragraphs in the first text file; and

displaying texts stored in the first text file on the display device at the calculated rate while simultaneously outputting audio signals decoded from the first audio file.
