Display power reduction using histogram metadata
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.
