DISPLAY POWER REDUCTION USING HISTOGRAM METADATA

摘要

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.

1. A method comprising:
identifying an optimal backlight value for at least one quality level of a first video segment; transmitting data for the first video segment, the transmitted data for the first video segment comprising a first message containing a first set of display adaptation information, wherein the first set of display adaptation information comprises the optimal backlight value for the at least one quality level of the first video segment; identifying a backlight value for the at least one quality level of a second video segment; determining a maximum backlight value change threshold between successive video segments; and applying temporal smoothing between the optimal backlight value for the at least one quality level of the first video segment and the backlight value for the at least one quality level of the second video segment based on the maximum backlight value change threshold.
