A mobile terminal comprising: a touch screen; and a controller configured to: control the touch screen to playback a first content and display a primary progress bar for controlling playback of the first content; receive a selective touch input for selecting two points (T1, T2) on the primary progress bar, the two points (T1, T2) defining an interval corresponding to a first portion of the first content, and a drag input for dragging the two points of the selective touch input in a direction outward from the two points (T1, T2), characterized in that the controller is configured to: control the touch screen to divide the touch screen into two sections (C1, C2) and playback the first content on a first section and second content, corresponding to the first portion on a second section, in response to the drag input; and control the touch screen to display a secondary progress bar, overlapped with the primary progress bar, for controlling playback of the first portion, and in that each progress indicator position of the primary progress bar and each progress indicator position of the secondary progress bar is changed over time, and the progress indicator position of the primary progress bar and the progress indicator position of the secondary progress bar are different from each other. a touch screen; and a controller configured to: control the touch screen to playback a first content and display a primary progress bar for controlling playback of the first content; receive a selective touch input for selecting two points (T1, T2) on the primary progress bar, the two points (T1, T2) defining an interval corresponding to a first portion of the first content, and a drag input for dragging the two points of the selective touch input in a direction outward from the two points (T1, T2), control the touch screen to playback a first content and display a primary progress bar for controlling playback of the first content; receive a selective touch input for selecting two points (T1, T2) on the primary progress bar, the two points (T1, T2) defining an interval corresponding to a first portion of the first content, and a drag input for dragging the two points of the selective touch input in a direction outward from the two points (T1, T2), characterized in that the controller is configured to: control the touch screen to divide the touch screen into two sections (C1, C2) and playback the first content on a first section and second content, corresponding to the first portion on a second section, in response to the drag input; and control the touch screen to display a secondary progress bar, overlapped with the primary progress bar, for controlling playback of the first portion, control the touch screen to divide the touch screen into two sections (C1, C2) and playback the first content on a first section and second content, corresponding to the first portion on a second section, in response to the drag input; and control the touch screen to display a secondary progress bar, overlapped with the primary progress bar, for controlling playback of the first portion, and in that each progress indicator position of the primary progress bar and each progress indicator position of the secondary progress bar is changed over time, and the progress indicator position of the primary progress bar and the progress indicator position of the secondary progress bar are different from each other.
