    Abstract: 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.

    Abstract: 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. The maximum 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.

    Abstract: A method includes identifying an optimal backlight value for at least one quality level of a first video segment. The method also includes transmitting data for the first video segment. The transmitted data for the first video segment includes a message containing a first set of display adaptation information. The first set of display adaptation information includes the optimal backlight value for the at least one quality level of the first video segment. The method further includes identifying a backlight value for the at least one quality level of a second video segment. The method also includes determining a maximum backlight value change threshold between successive video segments. In addition, the method includes applying temporal smoothing between the optimal backlight value and the backlight value based on the maximum backlight value change threshold.
