Abstract

A method for playing data in a playback apparatus is disclosed. The method includes playing the data stored in storing media installed in the playback apparatus with a playback acceleration.

Claims

1. A method for playing data in a playback apparatus, the method comprising:

calculating a playback acceleration of data to be played in the playback apparatus according to an acceleration time, an initial playback speed, and a target playback speed; and

playing the data stored in a storing media installed in the playback apparatus with the calculated playback acceleration.

2. The method of claim 1, wherein the playback acceleration is positive or negative but not zero.

3. The method of claim 1, wherein the playback acceleration is uniform.

4. A playback device comprising:

a storing module for storing data to be played;

an input module for inputting control parameters of playback acceleration of the data to be played stored in the storing module; and

a control module electrically connected to the storing module and the input module, for calculating the playback acceleration of data to be played in the playback device according to an acceleration time, an initial playback speed, and a target playback speed received by the input module, and for playing the data stored in the storing module with the calculated playback acceleration.

5. The device of claim 4, wherein the input module comprises an acceleration switch, and the playback device plays the data with an acceleration corresponding to the on status of the acceleration switch when the acceleration switch is turned on, and plays the data with a uniform speed when the acceleration switch is released.

6. The device of claim 5, wherein the acceleration switch is a lever.

7. The device of claim 5, wherein the acceleration switch is a press switch.

8. The device of claim 4, wherein the playback device further comprises a feedback device for indicating the speed status of the playback device.

9. The device of claim 8, wherein the feedback device indicates the speed status of the playback device using audio feedback.

10. The device of claim 8, wherein the feedback device indicates the speed status of the playback device using visual feedback.

11. The device of claim 8, wherein the feedback device indicates the speed status of the playback device using force feedback.

12. The device of claim 4, wherein the playback acceleration is positive or negative but not zero.

13. The device of claim 4, wherein the playback acceleration is uniform.
