Abstract

The present document relates to the presentation of visual data that is stored on a mobile communication device, in particular to the presentation of sequences of images such as slideshows that may further include animation sequences as well as static images. A method for displaying data includes: transferring visual data from a mobile communication device (100) to a rendering device (200) via a wireless communication link; transferring control data from the mobile communication device (100) to the rendering device (200); rendering the received visual data in the rendering device (200); and displaying the visual data, where the displaying of the visual data is controlled in accordance with the control data received from the mobile communication device (100).

Claims

1. A method for displaying visual data, including:

transferring control data and visual data from a mobile communication device to a rendering device via a wireless communication link;

rendering the received visual data at the rendering device; and

displaying the visual data;

wherein the displaying of the visual data is controlled in accordance with the control data received from the mobile communication device.

2. The method according to claim 1, wherein the visual data includes compressed image and/or video data.

3. The method according to claim 2, wherein the visual data is provided on the mobile communication device in a unified data format, the unified data format being a file container format that specifies layout and timing for displaying the visual data.

4. The method according to claim 3, further including:

transcoding the visual data into the unified data format at an external server; and

transferring the transcoded visual data to the mobile communication device.

5. The method according to claim 4, further including:

determining, at the server, that data which is to be sent to the mobile communication device includes visual data;

transcoding the visual data into the unified data format at the server; and

sending the transcoded visual data to the mobile communication device.

6. The method according to claim 4, further including:

determining, at the server, that data which is to be sent to the mobile communication device includes visual data;

storing the visual data at the server;

sending the visual data to the mobile communication device; and

upon a request issued by the mobile communication device, transcoding the visual data into the unified data format at the server and sending the transcoded visual data to the mobile communication device.

7. The method according to claim 1, wherein the visual data includes an animated presentation slide and the method includes:

generating video data for capturing the animation effects of the presentation slide

8. The method according to claim 1, wherein the visual data includes video data, and wherein the transcoding of the visual data includes setting one or more markers at time positions in the video data at which the display of video data is to be interrupted.

9. The method according to claim 1, wherein the visual data includes a plurality of media objects such as static images and/or movie clips, the method further including:

transferring media objects to the rendering device separately in response to user instructions.

10. The method according to claim 1, wherein the control data includes cursor position data, the method further including:

overlaying a cursor symbol on the displayed visual data in accordance with the cursor position data.

11. The method according to claim 10, further including:

generating the cursor position data according to signals from one or more acceleration sensors of the mobile communication device.

12. The method according to claim 10, further including:

generating the cursor position data according to signals from a touchscreen of the mobile communication device.

13. Mobile communication device, including:

a memory unit adapted to store visual data;

a communications subsystem adapted to transfer visual data and control data to a rendering device;

a user input device adapted to generate control data from user input in order to control the display of the visual data on an external display device.

14. The mobile communication device according to claim 13, wherein the user input device is further adapted to generate cursor position data for controlling a cursor that is displayed together with the visual data.

15. The mobile communication device according to claim 13, wherein the user input device includes a device movement interpreter.

16. The mobile communication device according to claim 13, wherein the user input device includes a touchscreen.

17. The mobile communication device according to claim 13, wherein

the visual data includes compressed image and/or video data and

the mobile communication device is configured to transfer each image or animated sequence to the rendering device separately in response to user instructions.

20. System including:

the mobile communication device according to claim 13, and

a file converter for receiving input documents from the mobile communication device, transforming input format to a unified animation format, and for returning the unified animation format to the mobile communication device.

18. Rendering device, including:

a communications subsystem adapted to receive visual data and control data from a mobile communication device; and

a rendering module adapted to render visual data received from the mobile communication device for display on a display device connected to the rendering device and to control the display of visual data in accordance with control data received from the mobile communication device.

19. The rendering device according to claim 18, wherein

the control data includes cursor position data, and

the rendering device is adapted to overlay a cursor symbol on the visual data based on the cursor position data.
