Abstract

Techniques are disclosed to select display settings for a display device. Device capabilities may be read from a display device and a determination made whether the device capabilities support other display formats than are read from the display, for example, a high dynamic range (HDR) format or a high resolution format. When the device capabilities do not include an format supported by a video source, video may be driven from the video source to the display device in the format and, if confirmation is received that the display device displays the driven video, settings may be stored for the display device identifying the format as a one supported by the display device. Additionally, interconnect may be tested by estimating noise levels generated by the interconnect to a network connection and/or by estimating network throughput both when video is driven over the interconnect and when it is not. Display formats may be selected for the device based on a maximum data rate of a network connection that can be maintained while the interconnect carries video.

First claim

We claim:

1. A method, comprising:
reading device capabilities from a display device,
determining whether the device capabilities include all formats supported by a video source;
when the device capabilities do not include all formats, driving video in a format of the video source that is omitted from the device capabilities to the display device,
when confirmation is received that the display device displays the driven video, storing settings for the display device identifying the display device as capable of displaying the driven format.

2. The method of claim 1 , wherein the driven video is in a high dynamic range video format.

3. The method of claim 1 , wherein the driven video is at a resolution higher than a resolution associated with formats of the device capabilities.

4. The method of claim 1 , wherein when a timeout condition is reached without receiving the confirmation, disqualifying the driven display format as a capability of the display device.

5. The method of claim 1 , wherein the confirmation is received from an operator of the display device.

6. The method of claim 1 , further comprising, prior to the driving, prompting an operator to perform a capability test, wherein the driving is performed in response to an operator response to the prompt.

7. The method of claim 1 , further comprising, after the reading, reading device capabilities of the device from a network repository.

8. The method of claim 1 , further comprising, after the storing, transmitting device settings to a network repository identifying the display device as capable of displaying the driven format.

9. The method of claim 1 , further comprising
estimating a level of interference noise generated by an interconnect over which the video is driven to the display device,
when the estimated level of interference noise exceeds a predetermined threshold, disqualifying the driven display format from use with the display device.

10. The method of claim 1 , further comprising
estimating a level of errors generated by a network transceiver in an interconnect that carries video to the display device,
disqualifying a candidate display format from use based on the estimated errors.

11. The method of claim 1 , further comprising
responsive to an operator input indicating that the display device displays the driven video format with errors, disqualifying the driven display format from use with the display device.

12. A video source, comprising;
an interconnect transceiver for connection to a display device via an interconnect, and
a processor and a memory, the processor to:
read device capabilities from a display device via the interconnect,
determine whether the device capabilities include all formats supported by the video source;
when the device capabilities do not include all formats, drive video in a format of the video source that is omitted from the device capabilities to the display device,
when confirmation is received that the display device displays the driven video, store in the memory settings for the display device identifying the display device as capable of displaying the driven format.

13. A non-transitory computer readable medium storing program instructions that, when executed by a processing device, cause the device to:
read device capabilities from a display device,
determine whether the device capabilities include all formats supported by a video source;
when the device capabilities do not include all formats, drive video in a format of the video source that is omitted from the device capabilities to the display device,
when confirmation is received that the display device displays the driven video, store settings for the display device identifying the display device as capable of displaying the driven format.

14. The medium of claim 13 , wherein the driven video is in a high dynamic range video format.

15. The medium of claim 13 , wherein the driven video is at a resolution higher than a resolution associated with formats of the device capabilities.

16. The medium of claim 13 , wherein the program instructions further cause the processing device to, when a timeout condition is reached without receiving the confirmation, disqualify the driven display format as a capability of the display device.

17. The medium of claim 13 , wherein the program instructions further cause the processing device to, prior to the driving, prompt an operator to perform a capability test, wherein the driving is performed in response to an operator response to the prompt.

18. The medium of claim 13 , wherein the program instructions further cause the processing device to, after the reading, read device capabilities of the device from a network repository.

19. The medium of claim 13 , wherein the program instructions further cause the processing device to, after the storing, transmit device settings to a network repository identifying the display device as capable of displaying the driven format.

20. The medium of claim 13 , wherein the program instructions further cause the processing device to:
estimate a level of interference noise generated by an interconnect over which the video is driven to the display device,
when the estimated level of interference noise exceeds a predetermined threshold, disqualify the driven display format from use with the display device.

21. The medium of claim 13 , wherein the program instructions further cause the processing device to:
estimate a level of errors generated by a network transceiver to an interconnect that carries video to the display device,
disqualify a candidate display format from use based on the estimated errors.

22. The medium of claim 13 , wherein the program instructions further cause the processing device to, responsive to an operator input indicating that the display device displays the driven video format with errors, disqualify the driven display format from use with the display device.

23. A method comprising:
sampling first noise from a network connection at a time when an interconnect between a video source and a display carries video data, and sampling second noise from the network connection at another time when the interconnect does not carry video data;
estimating a level of interference noise generated by the interconnect based on the first and the second noise; and
selecting a data rate of a subsequent video to transmit over the interconnect based on the estimated noise.

24. The method of claim 23 , further comprising:
driving video over the interconnect in a candidate display format at the selected data rate,
responsive to a confirmation that the video is displayed without error, storing the candidate display format as a setting of the display device.

25. The method of claim 23 , further comprising estimating a throughput of a network connection when the interconnect carries video data, wherein the data rate selection also is based on the estimated throughput.

26. The method of claim 23 , further comprising:
estimating a level of errors generated in the interconnect by a network transceiver,
disqualifying a candidate display format from use based on the estimated errors.

27. The method of claim 23 , further comprising:
driving video over the interconnect in a candidate display format at the selected data rate,
estimate transmission errors over the interconnect,
when the estimated transmission err
