Abstract

A playback positioning method and apparatus are provided. A determination is made as to whether a position selection mode is activated and a music file is selected from a music files list if the position selection mode is activated. The music file is partitioned into a plurality of segments which have identical percentages. The segments are mapped to reference keys, respectively and a progress status of the music file is displayed. Playback is positioned at a segment corresponding to the key input, while the music file is played. The quick selection of a playback position regardless of the length of the MP3 file is facilitated.

Claims

1. A playback positioning method for electric music file player, comprising:

partitioning a music file read from a storage into a plurality of segments; and

positioning playback at one of the segments, selected by a key input.

2. The method of claim 1, wherein the music file is at least partitioned into a specific percentage and a number of segments to be partitioned are input and the segments of the music file are mapped to reference number keys, respectively.

3. The method of claim 1 further comprising setting a position selection mode for setting a number of segments and links between the segments and keys.

4. The method of claim 1 further comprising displaying progress status of the music file.

5. A playback positioning method for an electric music file player, comprising:
