Abstract

A display apparatus comprises a display on which first video content of a video signal is presented. In addition, second video content is simultaneously presented e.g. superimposed on the first video content. A presentation processor (209) determines a first characteristic for the presentation of the first video content and a characteristics processor (211) determines a presentation characteristic for the second video content from the first characteristic. A transmitter (213) transmits the presentation characteristic to an external source of the second video content. A single device (401) may generate the video signal comprising both the first and second video content. In this case a characteristic of the overlaying is adjusted in response to the presentation characteristic. The invention may provide an advantageous adaptation of secondary (overlay) information to the current characteristics experienced when presenting primary video content.

Claims

1. A display apparatus comprising:

a display (201);

means (203) for receiving a video signal comprising first video content for presentation on the display (201);

means (209) for determining a first characteristic for presentation of the first video content on the display (201);

means (211) for determining a presentation characteristic for presentation of second video content on the display simultaneously with the first video content in response to the first characteristic; and

means (213) for communicating the presentation characteristic to an external source (105) of the second video content.

2. The display apparatus of claim 1 wherein the presentation characteristic is indicative of at least one of:

a size of a display window for presentation of the second video content;

an aspect ratio of a display window for presentation of the second video content;

a position of a display window for presentation of the second video content;

a size of a display window for presentation of the first video content;

an aspect ratio of a display window for presentation of the first video content;

a position of a display window for presentation of the first video content;

a pixel value range for presentation of the second video content;

a pixel value range for presentation of the first video content; and

a color characteristic.

3. The display apparatus of claim 1 wherein the presentation characteristic is a presentation window characteristic.

4. The display apparatus of claim 3 wherein the display apparatus is further arranged to communicate an indication of a full display window for the display (201) to the external source.

5. The display apparatus of claim 3 further arranged to switch between different presentation window modes for the first video content and wherein the presentation window characteristic is indicative of a current presentation window mode.

6. The display apparatus of claim 1 wherein the presentation characteristic is indicative of a geometric distortion of the first video content when presented on the display.

7. The display apparatus of claim 1 wherein the presentation characteristic is indicative of an availability of a secondary display means for presenting the second video content.

8. A video apparatus comprising:

a video port (505) for coupling the video apparatus to a display unit;

a video content source (501) for providing first video content;

an overlay processor (503) for generating an output video signal comprising both the first video content and overlay video content and for providing the output video signal to the video port;

means (507) for receiving a presentation characteristic from the display unit, the presentation characteristic being indicative of a presentation of the output video signal by the display unit; and

wherein

the overlay processor (503) is arranged to adjust a characteristic of the overlay video content in response to the presentation characteristic.

9. The video apparatus of claim 8 wherein the presentation characteristic comprises a rendering window characteristic for a presentation window for the output video signal;

the presentation window characteristic comprising at least one of an aspect ratio, a size and a position of the presentation window.

10. The video apparatus of claim 8 further comprising means for determining a content window characteristic for a window of the output video signal corresponding to the first video content;

and wherein the overlay processor (503) is further arranged to adjust a characteristic of the overlay video content in response to the content window characteristic.

11. The video apparatus of claim 8 wherein the overlay processor (503) is arranged to select a position of an overlay video object of the overlay video content in response to the presentation characteristic.

12. The video apparatus of claim 8 wherein the overlay processor (503) is arranged to select a dimension of an overlay video object of the overlay video content in response to the presentation characteristic.

13. The video apparatus of claim 8 wherein the overlay processor (503) is arranged to select a geometric distortion of an overlay video object of the overlay video content in response to the presentation characteristic.

14. The video apparatus of claim 8 wherein the presentation characteristic is indicative of a characteristic of a current visible window of the output video signal;

and the overlay processor (503) is arranged to adjust the second video content to be within the current visible window.

15. The video apparatus of claim 14 wherein the presentation characteristic comprises an aspect ratio for a displayed signal, and the overlay processor (503) is arranged to determine the current visible window in response to the aspect ratio and an aspect ratio for the output video signal.

16. The video apparatus of claim 14 wherein the overlay processor (503) is arranged to modify a position at least one graphic object to be adjacent an edge of the current visible window.

17. The video apparatus of claim 14 wherein the overlay processor (503) is arranged to locate at least some of the second video content outside a window corresponding to the first video content but within the current visible window when the window corresponding to the first video content is smaller than the current visible window.

18. The video apparatus of claim 8 wherein the presentation characteristic is indicative of a characteristic of a sub-window of a current visible window of the output video signal;

and the overlay processor (503) is arranged to adjust the second video content to be within the sub-window.

19. The video apparatus of claim 8 wherein the video content generator (501) is arranged to modify a parameter of the first video content in response to the presentation characteristic.

20. The video apparatus of claim 19 wherein the parameter is an upscaling parameter.

21. A method of operation for a display apparatus including a display (201);

the method comprising;

receiving a video signal comprising first video content for presentation on the display;

determining a first characteristic for presentation of the first video content on the display (201);

determining a presentation characteristic for presentation of second video content on the display (201) simultaneously with the first video content in response to the first characteristic; and

communicating the presentation characteristic to an external source (105) of the second video content.

22. A method of operation for a video apparatus including a video port for coupling the video apparatus to a display unit;

the method comprising;

providing first video content;

generating an output video signal comprising both the first video content and overlay video content;

providing the output video signal to the video port;

receiving a presentation characteristic from the display unit, the presentation characteristic being indicative of a presentation of the output video signal by the display unit; and

adjusting a characteristic of the overlay video content in response to the presentation characteristic.
