摘要： Segments for a video are transmitted in payload units with a supplemental enhancement information (SEI) message within which is embedded display adaptation information that may be employed to control display brightness and thereby reduce power consumption during display of the respective segment. The display adaptation information includes at least a maximum pixel brightness that may be used to scale pixel brightness to maximum and correspondingly reduce backlighting for liquid crystal displays, or to adjust the supply voltage for OLED displays. The display adaptation information may optionally include a minimum pixel brightness, a pixel histogram step size, and an indicator of scaling method.

摘要： Segments for a video are transmitted in payload units with an extended network abstraction layer unit (NALU) header or supplemental enhancement information (SEI) message within which is embedded display adaptation information that may be employed to control display brightness and thereby reduce power consumption during display of the respective segment. The display adaptation information includes at least a maximum pixel brightness that may be used to scale pixel brightness and correspondingly reduce backlighting for liquid crystal displays, or to adjust the supply voltage for OLED displays. m pixel brightness is set to a level saturating a portion of the pixel histogram without perceptual loss to the viewer, resulting in further reduction of power consumption.

摘要： Apparatus and methods scale a backlight of a display. A graphics processing unit (GPU) is configured to calculate a histogram. A central processing unit (CPU) is configured to control the backlight of the display responsive to a backlight level that is based on the histogram.
