Abstract

The present invention relates to a process and device for representation on a digital television screen.

The process for the representation on a digital television screen of a display comprising the representation of a video signal, the representation of applications and the representation of the navigator is characterized in that it comprises

• • a step of detecting the activation of the navigator,
  • a step of resizing the display of the video signal and the representation of applications according to one and the same homothetic reduction.

Claims

1. Process for generating for display on a display device a representation of a video signal, at least one representation of an application, and a representation of a navigator, the process comprising the steps of:

generating a graphics area displaying the representation of the video signal, the at least one representation of an application, and the representation of the navigator;

detecting an activation of the navigator,

resizing the representation of the video signal and the at least one representation of an applications according to a homothetic reduction, in a first mode of operation, and

resizing by reducing the representation of the video signal, in a second mode of operation, wherein the area occupied by the at least one representation of an application is the same during said resizing step.

2. A process according to claim 1, wherein the representation of the navigator occupies the area left vacant by the homothetic reduction of the representation of the video signal and the at least one representation of an application in the first mode of operation and the representation of the navigator occupies the area left vacant by the resized representation of the representation of the video signal in the second mode of operation.

3. Process for generating for a display device a representation of a video signal, at least one representation of an applications, and a representation of a navigator, the process comprising the steps of:

detecting a deactivation of the navigator,

resizing the representation of the video signal and the at least one representation of an application according to a homothetic increase, in a first mode of operation, and

resizing by expanding the representation of the video signal, in a second mode of operation, wherein the area occupied by the at least one representation of an application is the same during said resizing step.

4. Process according to claim 3, wherein the representation of the video signal and the at least one representation of the applications occupy the entire graphics area.

5. A device for generating for display a representation of a video signal, at least one representation of an application, and a representation of a navigator comprising:

a control module comprising

a means for detecting the activation of the navigator,

a means for detecting a modification in a state of activation of the navigator

a repositioning reformatter for resizing the representation of the video signal and the at least one representation of an application that operates in view of the means for detecting a modification in the state of activation of the navigator by resizing the representation of the video signal and the at least one representation of an application in a first mode of operation and resizing the representation of the video signal leaving unaffected the at least one representation of an application in a second mode of operation

a mixer for mixing the representation of the video signal and the representation of the at least one representation of an application, and the representation of the navigator.

6. A device according to claim 5, wherein the repositioner reformatter circuit is associated with at least one representation of an application.

7. A device according to claim 5, wherein said device is a display device.
