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.

Description

technical field [0001] The present invention relates to a mobile phone including MPEG-1 Layer 3 (MP3) playback. More specifically, the present invention relates to a playback positioning method for MP3 files in MP3-enabled mobile phones, which is capable of splitting the MP3 file into segments with equal percentages and mapping the segments to individual Numeric keys to quickly select the playback position regardless of the length of the MP3 file. Background technique [0002] In recent years, mobile phones equipped with MP3 playback modules have been widely used. These types of mobile phones are able to seek the starting point of an MP3 file and move the playback position by pressing a fast forward or rewind key while playing it. When the fast-forward or rewind keys are used to find out the playback position, it takes a long time to find out the exact playback position. This is even more so when the MP3 songs are long. [0003] Playing MP3 songs using an MP3 player such...
