Abstract
Signaling a display device to automatically characterize a video signal is disclosed. In a method of an embodiment of the invention, a display device that has a video signal characterization circuit is signaled to automatically characterize a video signal of a video source. A predetermined characterization image is provided on the video signal of the video source for the display device to automatically characterize.
Claims34
A method comprising:
- signaling a display device having a video signal characterization circuit to automatically characterize a video signal of a video source;
- providing a predetermined characterization image on the video signal of the video source for the display device to automatically;
- and,
- removing the predetermined characterization image from the video signal of the video source after waiting a length of time and/or after waiting for the display device to signal that characterization has been completed.
1 more element
A method comprising:
- automatically characterizing by a display device having a video signal characterization circuit of a video signal of a video source on which a predetermined characterization image has been provided;
- and,
- displaying an image other than the predetermined characterization image by the display device while automatically characterizing the video signal,
- wherein the predetermined characterization image is removed from the video signal of the video source after a length of time has been waited for and/or after the display device has signaled that characterization has been completed.

A method comprising:
- by a video source,
- signaling a display device having a video signal characterization circuit to automatically characterize a video signal of the video source;
- providing a predetermined characterization image on the video signal of the video source for the display device to automatically character;
- by the display device,
- automatically characterizing the video signal of the video source on which the predetermined characterization image has been provided;
- displaying an image other than the predetermined characterization image while automatically characterizing the video signal;
- by the video source,
- removing the predetermined characterization image from the video signal of the video source after waiting a length of time and/or after waiting for the display device to signal that characterization has been completed.
5 more elements
A video source comprising:
- a video signal having a predetermined characterization image;
- and,
- a mechanism to signal to a display device having a video signal characterization circuit to automatically characterize the video signal, and to remove the predetermined characterization image from the video signal of the video source after a length of time has been waited for and/or after the display device has signaled that characterization has been completed.
A video source comprising:
- a video signal having a predetermined characterization image;
- and,
- means for signaling to a display device having a video signal characterization circuit to automatically characterize the video signal, and for removing the predetermined characterization image from the video signal of the video source after a length of time has been waited for and/or after the display device has signaled that characterization has been completed.
A display device comprising:
- a display mechanism to display a video signal of a video source;
- a characterization circuit to automatically characterize the video signal of the video source based on a predetermined characterization image on the video signal;
- and,
- a signal mechanism to receive a signal to indicate to the characterization circuit to automatically characterize the video signal of the video source,
- wherein the predetermined characterization image is removed from the video signal of the video source after a length of time has been waited for and/or after the display device has signaled that characterization has been completed.

A display device comprising:
- a characterization circuit to automatically characterize a video signal of a video source based on a predetermined characterization image on the video signal;
- and,
- means for receiving a signal to indicate to the characterization circuit to automatically characterize to the video signal of the video source,
- wherein the predetermined characterization image is removed from the video signal of the video source after a length of time has been waited for and/or after the display device has signaled that characterization has been completed.
1 more element
A display device comprising:
- a characterization circuit to automatically characterize a video signal of a video source based on a predetermined characterization image on the video signal;
- and,
- a display mechanism to display the video signal of the video source, the display mechanism displaying an image other than the video signal while the characterization circuit automatically characterizes the video signal,
- wherein the predetermined characterization image is removed from the video signal of the video source after a length of time has been waited for and/or after the display device has signaled that characterization has been completed.
1 more element
A system comprising:
- a video source capable of signaling a display device to automatically characterize a video signal of the video source and capable of providing a predetermined characterization image on the video signal for the display device to automatically characterize;
- and,
- a display device capable of receiving the signaling from the video source to automatically characterize the video signal and capable of automatically characterizing the video signal of the video source,
- wherein the video source is to remove the predetermined characterization image from the video signal of the video source after a length of time has been waited for and/or after the display device has signaled that characterization has been completed.
