Abstract

A multimedia player has a fast seek function for navigating between track selections contained within a large playlist. By holding down a seek-up or a seek-down button, a selection identifying display scrolls through the selections in a playlist in single steps until a multiple of 10 is reached. If a minimum number of single steps (e.g., 4) have been taken, then the display begins to jump by 10'"'"'s. Otherwise, single steps are taken until the next multiple of 10. Single stepping is again used when the display nears the beginning or end of the playlist.

Claims

1. A method of fast seeking from a current selection to a desired selection within an ordered playlist of selections for reproduction by a media player, each selection in said ordered playlist having a corresponding selection number between a first selection number and a last selection number, said method comprising the steps of:

displaying selection identifying data of said current selection on a display;

performing a control action indicating either a seek-up or a seek-down command;

performing a control action to establish a fast seek interval;

displaying selection identifying data for interim selections on said display according to a predetermined sequence of said selection numbers wherein said interim selection is indexed to successive selections in said sequence in an increasing order in response to said seek-up command and is indexed to successive selections in said sequence in a decreasing order in response to said seek-down command, and wherein said sequence indexes said interim selection number in single steps until said interim selection number has a predetermined modulo value and then indexes said interim selection number by a jump step, each selection identifying data for each interim selection in said sequence being displayed for a predetermined display time;

performing a control action to terminate said fast seek interval, wherein an interim selection having selection identifying data being displayed at the termination of said fast seek interval is a chosen selection; and

reproducing said chosen selection.

2. The method of claim 1 wherein said media player includes a seek-up push button and a seek-down push button, and wherein said control action indicating either a seek-up or a seek-down command is comprised of prressing said seek-up push button or said seek-down push button, respectively.

3. The method of claim 2 wherein said control action to establish said fast seek interval is comprised of continuing to press said seek-up push button or said seek-down push button throughout said fast seek interval.

4. The method of claim 3 wherein said control action to terminate said fast seek interval is comprised of releasing said seek-up push button or said seek-down push button.

5. The method of claim 1 wherein said predetermined modulo value is comprised of zero with a modulus of ten.

6. The method of claim 1 wherein said jump step indexes said selection number by ten.

7. The method of claim 1 wherein said sequence includes at least a predetermined minimum number of single steps before using said jump step.

8. The method of claim 7 wherein said predetermined modulo value is comprised of zero with a modulus of ten, wherein said jump step indexes said selection number by ten, and wherein said predetermined minimum number is equal to four.

9. The method of claim 1 wherein, after incrementing said interim selection number by said jump step, said sequence reverts to said single step when said interim selection number is within a predetermined range of said first selection number or said last selection number and then wraps between said first selection number and said last selection number.

10. The method of claim 9 wherein, after wrapping between said first selection number and said last selection number, said sequence indexes said interim selection number in said single steps until said interim selection number reaches said predetermined modulo value and then resumes indexing with said jump step.

11. The method of claim 1 wherein said media player reproduces said selections from a predetermined media, wherein said media has a plurality of directories, and wherein said playlist is comprised of selections within one of said directories.

12. The method of claim 1 wherein said current selection continues to be reproduced during said fast seek interval.

13. The method of claim 1 wherein said predetermined display time has a first duration while said sequence is indexing at said single steps and has a second duration while said sequence is indexing at said jump steps, said second duration being shorter than said first duration.

14. The method of claim 13 wherein said first duration is equal to about 500 milliseconds and said second duration is equal to about 333 milliseconds.

15. The method of claim 1 wherein indexing by said jump step is disabled and said interim selection number is indexed only in single steps of a total number of selections in said playlist is less than a predetermined number.

16. A media player for reproducing selections from a media containing an ordered playlist of selections, each selection in said ordered playlist having a corresponding selection number between a first selection number and a last selection number, said media player performing a fast seek from a current selection to a desired selection within said playlist, said media player comprising:

a display showing selection identifying data;

a user control interface for indicating either a seek-up or a seek-down command, for establishing a fast seek interval, and for terminating said fast seek interval; and

a controller responsive to said user control interface for controlling said fast seek to display selection identifying data for interim selections on said display according to a predetermined sequence of said selection numbers wherein said interim selection is indexed to successive selections in said sequence in an increasing order in response to said seek-up command and is indexed to successive selections in said sequence in a decreasing order in response to said seek-down command, wherein said sequence indexes said interim selection number in single steps until said interim selection number has a predetermined modulo value and then indexes said interim selection number by a jump step, and wherein each selection identifying data for each interim selection in said sequence is displayed for a predetermined display time, said controller switching to reproduction of a chosen selection comprised of the interim selection with its selection identifying data being displayed when said fast seek interval is terminated.

17. The media player of claim 16 wherein said user control interface is comprised of a seek-up push button and a seek-down push button.

18. The media player of claim 17 wherein said fast seek interval is established by pressing and holding said seek-up push button or said seek-down push button throughout said fast seek interval and releasing said seek-up button or said seek-down button to terminate said fast seek interval.

19. The media player of claim 16 wherein said predetermined modulo value is comprised of zero with a modulus of ten and wherein said jump step indexes said selection number by ten.

20. The media player of claim 16 wherein said sequence includes at least a predetermined minimum number of single steps before using said jump step.

21. The media player of claim 16 wherein, after incrementing said interim selection number by said jump step, said sequence reverts to said single step when said interim selection number is within a predetermined range of said first selection number or said last selection number and then wraps between said first selection number and said last selection number.

22. The media player of claim 21 wherein, after wrapping between said first selection number and said last selection number, said sequence indexes said interim selection number in said single steps until said interim selection number reaches said predetermined modulo value and then resumes indexing with said jump step.

23. The media player of claim 16 wherein said media has a plurality of directories and wherein said playlist is comprised of selections within one of said directories.

24. The media player of claim 16 wherein said predetermined display time has a first duration while said sequence is indexing at said single steps and has a second duration while said sequence is indexing at said jump steps, said second duration being shorter than said first duration.

25. The media player of claim 16 wherein said selections are comprised of compressed audio files stored on said media.

26. The media player of claim 25 wherein said compressed audio files are comprised of mp3 files.

27. The media player of claim 25 wherein said media is comprised of a compact disc.
