Abstract

In the present invention, a method and apparatus are provided for reproducing multimedia files, wherein the selection probability of the multimedia files is adjusted according to a user'"'"'s preference and a multimedia file is randomly selected and played according to the selection probability. The selection probability of the multimedia files is adjusted according to the user'"'"'s preference; a user can listen to undesired multimedia files less frequently than other multimedia files even when the multimedia files are randomly selected.

wherein each skip of the selected multimedia file between the first and hundredth skip decreases the weighting factor by 0.01.

7. The method of claim 6, wherein the selection information includes a number of times the selected multimedia file is skipped while being reproduced.

8. The method of claim 7, wherein the selected multimedia file is skipped via an input received by a skipping input unit.

9. The method of claim 6, wherein the selection information includes a number of times the selected multimedia file is selected to increase its probability of being reproduced.

10. The method of claim 6, wherein reproducing the selected multimedia file comprises:

updating the selection information of the selected multimedia file via the multimedia file reproduction unit when the selected multimedia file is skipped while being reproduced;

updating the selection information of the selected multimedia file via the multimedia file reproduction unit when the selected multimedia file is selected to increase its probability of being reproduced; and

reproducing the another multimedia file via the multimedia file reproduction unit.

11. An apparatus for reproducing multimedia files, the apparatus comprising:

a memory for storing one or more multimedia files and selection information related a skipping command; and

a control unit for selecting and reproducing a multimedia file of the one or more stored multimedia files that is randomly selected according to the stored selection information, wherein the control unit comprises;

a random selection processing unit for randomly selecting the multimedia file according to multimedia file selection weighting ratios, and

a multimedia file reproduction unit for reproducing the selected multimedia file, for updating the stored selection information related to the selected multimedia file, and for selecting and reproducing another multimedia file of the one or more stored multimedia files when the selected multimedia file is skipped,

wherein the selection information includes a number of times the selected multimedia file is skipped while being reproduced,

wherein the selection information includes a number of times the selected multimedia file is selected to increase its probability of being reproduced,

wherein the random selection processing unit includes a weighting factor processing unit for calculating the multimedia file selection weighting ratios using the selection information,

wherein the selection information includes an integer number of times between 1 and 100 that the selected multimedia file is skipped while being played;

wherein the weighting factor is inversely proportional to the selection information and is represented as a real number between 0 and 1; and

wherein each skip of the selected multimedia file between the first and hundredth skip decreases the weighting factor by 0.01.

12. The apparatus of claim 11, wherein the selected multimedia file is skipped in response to input received via a fast forward function.
