Abstract

The present disclosure involves a method of managing media playback. The method includes displaying a media program on a touch screen of an electronic device. The method includes detecting, via the touch screen, an input from a user indicating that the user wishes to fast forward or rewind the media program. The method includes triggering, in response to the detected input from the user, an appearance of a scroll bar including an indicator on the touch screen. The indicator is configured to be moved along the scroll bar. A length of the scroll bar represents a predefined amount of time that is a fraction of a total duration of the media program. A position of the indicator relative to the scroll bar corresponds to a time location of the media program.

displaying a second scroll bar and a second indicator, wherein the second indicator is configured to be moved along the second scroll bar, wherein a length of the second scroll bar represents a predefined amount of time that is less than the total time duration of the media program and wherein a position of the second indicator relative to the second scroll bar corresponds to a time location of the media program; and

thereafter navigating the media program using the second scroll bar in response to the detected movement of the second indicator along the second scroll bar.

2. The electronic device of claim 1, wherein the displaying the second scroll bar comprises displaying the second scroll bar and the first scroll bar simultaneously.

3. The electronic device of claim 1, wherein the displaying the second scroll bar comprises replacing the first scroll bar with the second scroll bar on the touch screen.

4. The electronic device of claim 1, wherein the displaying the second scroll bar is performed such that the length of the first scroll bar and the length of the second scroll bar have similar sizes.

5. The electronic device of claim 1, wherein the predefined amount of time represented by the length of the second scroll bar is a function of the measured speed of the first indicator.

6. The electronic device of claim 5, wherein the predefined amount of time represented by the length of the second scroll bar is the function of the measured speed of the first indicator in a manner such that, while the length of the second scroll bar remains the same:

as the measured speed of the first indicator decreases, the predefined amount of time decreases; and

as the measured speed of the first indicator increases, the predefined amount of time increases.

7. A method of managing media playback, comprising:

displaying a media program on a touch screen of an electronic device;

detecting a user gesture performed on the touch screen;

displaying a first scroll bar including a first indicator on the touch screen, wherein the first indicator is configured to be moved along the first scroll bar, wherein a length of the first scroll bar represents a total time duration of the media program, and wherein a position of the first indicator relative to the first scroll bar corresponds to a time location of the media program;

detecting, via the touch screen, the user'"'"'s movement of the first indicator along the first scroll bar, wherein the user'"'"'s movement of the first indicator occurs at a non-zero speed;

measuring a speed of the first indicator;

when the measured speed of the first indicator exceeds a predefined reference speed, navigating the media program at a rate that is a function of the speed of the first indicator, wherein the navigating is performed using the first scroll bar; and

when the measured speed of the first indicator is less than the predefined speed but is greater than a zero-speed, performing the following actions;

displaying a second scroll bar and a second indicator, wherein the second indicator is configured to be moved along the second scroll bar, wherein a length of the second scroll bar represents a predefined amount of time that is less than the total time duration of the media program and wherein a position of the second indicator relative to the second scroll bar corresponds to a time location of the media program; and

thereafter navigating the media program using the second scroll bar in response to the detected movement of the second indicator along the second scroll bar.

8. The method of claim 7, wherein the displaying the media program includes one of:

streaming the media program to the electronic device from an online database via a wireless or wired telecommunications protocol; and

playing the media program that is stored locally on the electronic device.

9. The method of claim 7, wherein the displaying of the second scroll bar and the second indictor is performed in a manner such that the second indicator is initially positioned in a center of the second scroll bar, and wherein a movement of the second indicator in a first direction corresponds to a rewinding of the media program, and wherein a movement of the second indicator in a second direction opposite the first direction corresponds to a fast forwarding of the media program.

10. The method of claim 7, wherein the displaying the second scroll bar comprises displaying the second scroll bar and the first scroll bar simultaneously.

11. The method of claim 7, wherein the displaying the second scroll bar comprises replacing the first scroll bar with the second scroll bar on the touch screen.

12. The method of claim 7, wherein the displaying the second scroll bar is performed such that the length of the first scroll bar and the length of the second scroll bar have similar sizes.

13. The method of claim 7, wherein the predefined amount of time represented by the length of the second scroll bar is a function of the measured speed of the first indicator.

14. The method of claim 13, wherein the predefined amount of time represented by the length of the second scroll bar is positively correlated with the measured speed of the first indicator.

15. A system for playing digital media, comprising:
