    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.

    Abstract translation: 一种方法包括为第一视频段的至少一个质量水平识别最佳背光值。 该方法还包括发送用于第一视频段的数据。 第一视频段的发送数据包括包含第一组显示适配信息的消息。 第一组显示适配信息包括用于第一视频段的至少一个质量水平的最佳背光值。 该方法还包括识别用于第二视频段的至少一个质量水平的背光值。 该方法还包括确定连续视频段之间的最大背光值改变阈值。 此外，该方法包括基于最大背光值改变阈值在最佳背光值和背光值之间应用时间平滑。
