摘要

The invention concerns a device and a method for controlling playback of digital multimedia data as well as a corresponding computer-readable storage means and a corresponding computer program which are usable for facilitating controlling of digital multimedia data, especially of controlling digital audio data when DJing using a tablet computer, for instance for "scratch" effect. For this purpose a device for controlling playback of digital multimedia data is proposed, which comprises at least a first and a second touch sensitive portion for data input and data output. The device is configured for displaying in the first and the second portion a representation of at least a part of the multimedia data, where in the first portion a representation of a part of the multimedia data, which is displayed on the second portion, is displayed, and where the first portion is operatable in at least a first and a second mode, where - in the first mode independently of a position of a touch point a direction and a speed of the playback is controllable in dependence of a change of the touch point, and - in the second mode a new playback position is definable in dependence of the position of the touch point, for displaying in the second portion a marker for indicating on the second portion within the representation of the multimedia data a neighbourhood around the playback position, and for switching the modus of the first portion, when the marker is moved by user input.
