Abstract

A system and method for determining the characteristics of a device coupled to a client device are disclosed. A method, according to one embodiment, includes driving a display device with a first video output signal formatted according to a first video interface specification; responsive to driving the display device, soliciting user input based on information included in the first video output signal; determining a characteristic of the display device based on the user input; and driving the display device according to the determined characteristic.

Claims

1. A system, comprising:

processing logic configured to effect the presentation of objects on a display screen of a display device that are altered by one or more pipelines, the processing logic configured to solicit a response by a user, the processing logic further configured to, responsive to the user input, determine the de-interlacing capabilities of the display device.

2. The system of claim 1, wherein the display device includes a television set.

3. The system of claim 1, wherein the processing logic is further configured to determine the de-interlacing capabilities of the client device.

4. The system of claim 3, wherein the one or more pipelines further comprises:

a media memory configured to store one or more consecutive interlaced pictures; and

circuit logic configured to;

access an interlaced pictures from the memory;

process a plurality of lines from a field corresponding to the interlaced picture; and

generate each line of a resulting progressive picture.

5. The system of claim 4, wherein the processing logic is further configured to effect the display of the progressive picture on the display screen and solicit further user response based on the perceived quality of the display of the progressive picture.

6. The system of claim 5, wherein the processing logic is further configured to determine whether the de-interlacing capabilities of the client device or of the display device should be used based on the further user response, wherein the processing logic is further configured to responsively implement the superior quality de-interlacing capabilities.

7. The system of claim 4, wherein the processing logic is further configured to determine the de-interlacing capabilities based on an input corresponding to analog signals, interlaced standard definition (SD) pictures received as compressed digital signals, interlaced high definition (HD) pictures received as compressed digital signals, or a combination of two or more.

8. The system of claim 4, wherein the circuit logic is programmable.

9. The system of claim 3, wherein the one or more pipelines further comprises:

a media memory configured to store one or more consecutive interlaced pictures; and

circuit logic configured to;

access plural interlaced pictures from the memory;

process a plurality of lines from plural field corresponding to the plural interlaced pictures; and

generate each line of resulting plural progressive pictures.

10. The system of claim 9, wherein the processing logic is further configured to effect the display of the plural progressive pictures on the display screen and solicit further user response based on the perceived quality of the display of the plural progressive pictures.

11. The system of claim 10, wherein the processing logic is further configured to determine whether the de-interlacing capabilities of the client device or of the display device should be used based on the further user response, wherein the processing logic is further configured to responsively implement the superior quality de-interlacing capabilities.

12. The system of claim 9, wherein the processing logic is further configured to determine the de-interlacing capabilities based on an input corresponding to analog signals, interlaced standard definition (SD) pictures received as compressed digital signals, interlaced high definition (HD) pictures received as compressed digital signals, or a combination of two or more.

13. The system of claim 9, wherein the circuit logic is programmable.

14. The system of claim 1, wherein the processing logic is embodied in a network client device capable of outputting video and audio in at least one defined format through at least one port.

15. The system of claim 1, wherein the processing logic is further configured to determine the de-interlacing capability of the display device by effecting an output to the display device of graphical objects with alternate lines displaced or shifted by varied amounts based on operations of the one or more pipelines.

16. The system of claim 15, wherein the determination of de-interlacing capabilities of the display device includes a determination of whether the display device has de-interlacing capabilities, the quality of the de-interlacing capabilities, or a combination of both.

17. The system of claim 15, wherein the one or more pipelines are further configured to generate the graphical objects based on one or more two-dimensional transformations, one or more three-dimensional transformations, or a combination of both.

18. A method, comprising:

altering one or more objects corresponding to one or more pictures;

de-interlacing by a client device one or more fields corresponding to the altered one or more objects;

outputting the altered objects and the de-interlaced altered objects on a display screen of a display device; and

soliciting user input to determine a quality of one or more rendered displays on the display screen, the one or more rendered displays based on the outputted altered objects that are de-interlaced at the display device and the de-interlaced altered objects provided by the client device.

19. The method of claim 18, further comprising determining whether the de-interlacing capabilities of the display device or the de-interlacing capabilities of the client device are superior.

20. A system, comprising:

means for altering one or more objects;

means for outputting the altered one or more objects on a display screen;

means for soliciting a response by a user in association with the displayed objects; and

means for determining the de-interlacing capabilities of the display device responsive to the user input.
