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 of a client device configured to effect the presentation of objects on a display screen of a display device coupled to the client device that are altered by one or more pipelines, the processing logic of the client device configured to solicit a response by a user, the processing logic of the client device further configured to, responsive to the response from the user, determine de-interlacing capabilities of the display device coupled to the client device, the processing logic of the client device further configured to determine de-interlacing capabilities of the client device and then determine if the de-interlacing capabilities of the client device should be bypassed in favor of the de-interlacing capabilities of the display device.

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

3. The system of claim 1, 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 picture 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.

4. The client device of claim 3, wherein the processing logic is further configured to affect a display of the progressive picture on the display screen and solicit further user response based on a perceived quality of the display of the progressive picture.

5. The client device of claim 4, 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 de-interlacing capabilities of the client device or of the display device.

6. The client device of claim 3, 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.

7. The client device of claim 3, wherein the circuit logic is programmable.

8. The client device of claim 1, 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 media memory;

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

generate each line of resulting plural progressive pictures.

9. The client device of claim 8, wherein the processing logic is further configured to affect a display of the plural progressive pictures on the display screen and solicit further user response based on a perceived quality of the display of the plural progressive pictures.

10. The client device of claim 9, 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.

11. The client device of claim 8, wherein the processing logic is further configured to determine the de-interlacing capabilities of the client device or of the display device 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.

12. The client device of claim 8, wherein the circuit logic is programmable.

13. The client device 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.

14. The client device of claim 1, wherein the processing logic is further configured to determine the de-interlacing capability of the display device by affecting 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.

15. The client device of claim 14, 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.

16. The client device of claim 14, 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.

17. 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 coupled to the client device;

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;

determining via the client device de-interlacing capabilities of the display device coupled to the client device and de-interlacing capabilities of the client device; and

determining if the de-interlacing capabilities of the client device should be bypassed in favor of the de-interlacing capabilities of the display device.
