1. A method comprising:
- identifying a first display content to be displayed at a first time;
identifying a second display content to be displayed at a second time, wherein the second time is after the first time;
providing display data to a display port at a first frame rate if the first display content is different from the second display content;
providing display data to the display port at a second frame rate if the first display content is substantially the same as the second display content, wherein the second frame rate is less than the first frame rate;
enabling a first clock rate if the first display content is different from the second display content; and
enabling a second clock rate if the first display content is substantially the same as the second display content, wherein the second clock rate is less than the first clock rate.

Abstract
A system and method are provided for reducing power consumption within a video processing portion of a system based on display content. Display content is monitored to determine whether the display content is changing. New display content is compared to old display content to determine if the display content is changing. If the display content has not changed, a frame rate used to output display data is reduced. A color depth associated with the display data is also reduced. Power consumption can be reduced when it is determined that display content is not changing.

8. A method comprising:
-
identifying a first display content to be displayed at a first time; identifying a second display content to be displayed at a second time, wherein the second time is after the first time; providing display data to a display port at a first frame rate if the first display content is different from the second display content; providing display data to the display port at a second frame rate if the first display content is substantially the same as the second display content, wherein the second frame rate is less than the first frame rate; identifying a third display content to be displayed at a third time, wherein the third time is after the second time; providing display data with a first color depth if the third display content is different from the first display content; and providing display data with a second color depth if the third display content is substantially the same as the first display content, wherein the second color depth is less than the first color depth.

19. A system comprising:
-
a content analyzer to compare a first display content to be displayed at a first time with a second display content to be displayed at a second time, wherein the second time is after the first time; a display module to alter a frame rate for providing display data to a display port, wherein said frame rate is based on the comparison performed by said content analyzer; a power module to; enable a first clock rate if said content analyzer determines the first display content is different from the second display content; and enable a second clock rate if said content analyzer determines the first display content is substantially the same as the second display content, wherein said second clock rate is less than said first clock rate; and said display port to output said display data. - View Dependent Claims (20, 21, 22)

23. A system comprising:
-
a content analyzer to; compare a first display content to be displayed at a first time with a second display content to be displayed at a second time, wherein the second time is after the first time; and compare a third display content to be displayed at a third time with the first display content, wherein the third time is after the second time; a display module to; alter frame rate for providing display data to a display port, wherein said frame rate is based on the comparison performed by said content analyzer; provide display data with a first color depth if the content analyzer determines the third display content is different from the first display content; and provide display data with a second color depth if the content analyzer determines the third display content is substantially the same as the first display content; and said display port to output said display data.
