Multimedia playing method and apparatus using the same

A multimedia playing method, suitable for a multimedia playing apparatus, wherein the multimedia playing apparatus has a memory and K audio files, and K>0, the multimedia playing method comprising:

• receiving N audio files selected by a user, wherein 0<N≦K;
• determining whether N is smaller than a predetermined number;
• if N is smaller than the predetermined number, retrieving each N audio file for a predetermined size, and planning a first section of the memory for storing the predetermined size of the N audio files;
• and
• if N is not smaller than the predetermined number, planning a first section of the memory to store each initial part of the N audio files according to N, wherein the first section of the memory is evenly distributed to each audio file.

A multimedia playing apparatus, comprising:

• a storage unit, for providing K audio files, wherein K>0;
• a multimedia input interface, coupled to the storage unit, for receiving the K audio files;
• a user interface, for receiving N audio files selected by a user, wherein 0<N≦K;
• a memory, coupled to the multimedia input interface, having a first section and a second section, wherein the first section is used for storing initial parts of the N audio files, and the second section is used for storing subsequent parts of the N audio files;
• and
• a control unit, coupled to the multimedia input interface, the user interface, and the memory, for adjusting capacities of the first section and the section,
• wherein the control unit first detects a format and encoding information of the N audio files and then determines whether total memory space required by the N audio files to be played for a predetermined time is smaller than a predetermined value and adjusts capacities of the first section and the second section accordingly.
