Abstract

A device for controlling playback of digital multimedia displays in first and second portion a representation of 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 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 a neighbourhood around the playback position, and
• for switching the modus of the first portion, when the marker is moved by user input.

Claims

1. Device for controlling playback of digital multimedia data through user interaction during playback, the device comprising at least a first and a second touch sensitive portion for data input and data output, and where the device is configured

for displaying in the first portion a representation of at least a first part of the multimedia data and in the second portion a representation of at least a second part of the multimedia data, where the first part represents a part of the second part, 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.

2. Device according to claim 1, where the device is configured for setting the at least one first portion from the second mode into the first mode in reaction of a user input into the at least one first portion.

3. Device according to claim 1, where the device is configured for displaying the representation in a predefined resolution within the first portion.

4. Device according to claim 1, where the marker is realized as a frame, and where the device is configured is such a way that the representation, which is displayed on the first portion, corresponds to the representation, which is displayed in the frame.

5. Device according to claim 1, where the device is configured for changing the size of the marker in reaction of a user input via the first or second touch sensitive portion.

6. Device according to claim 1, where the device is configured for displaying at least in one of the first and second portion an indicator for indicating a current playback position within the multimedia data.

7. Device according to claim 1, where the device comprises at least two first and at least two second touch sensitive portions, where in a first pair of first and second portions representations of a first set of multimedia data, and in a second pair of first and second portions representations of a second set of multimedia data is displayed.

8. Device according to claim 1, where the device is realized as a portable data processing unit.

9. Device according to claim 1, where the device is configured for continuing in the first mode playback from the current playback position with the direction and the speed of the playback defined by the change of the touch point.

10. Device according to claim 1, where the device is configured for continuing in the second mode playback from the new playback position.

11. Method for controlling playback of digital multimedia data through user interaction during playback, where at least a first and a second touch sensitive portion for data input and data output is provided, and wherein in the first portion a representation of at least a first part of the multimedia data and in the second portion a representation of at least a second part of the multimedia data is displayed, where the first part represents a part of the second part, 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, and

wherein in the second portion a marker is displayed for indicating on the second portion within the representation of the multimedia data a neighbourhood around the playback position, and the modus of the first portion is switched, when the marker is moved by user input.

12. Non-transitory computer-readable storage means on which a program is stored that enables a data processing system, once the program has been loaded into the memory of the data processing system, to execute a method for controlling playback of digital multimedia data according to claim 11.
