    Abstract: Power levels of a backlight are adjusted in a number of ways and based on a number of criteria. The adjustments result in a lower power consumption and, in some cases, may enhance audience attention to important objects in a scene. The adjustments comprise, for example, a combination of ramping down power (lowering final display brightness) in concert with corresponding compensatory LCD adjustments (increasing final display brightness). The adjustments may also include, for example, system dimming after ramp down/LCD adjustments are exhausted, or the shifting of an LDR2HDR curve.

    Abstract translation: 背光的功率水平以多种方式进行调整，并且基于多个标准。 该调整导致较低的功率消耗，并且在某些情况下可以增强观众对场景中重要对象的关注。 调整包括例如与对应的补偿LCD调整（增加最终显示亮度）一起的降低功率（降低最终显示亮度）的组合。 调整还可以包括例如在斜坡下降/ LCD调节耗尽之后的系统调光或LDR2HDR曲线的移位。

    Abstract: Systems, apparatus and methods are provided for generating, delivering, processing and displaying video data to preserve the video creator=s creative intent. Metadata which may be used to guide the processing and display of the video data is dynamically generated and embedded in the video data throughout a video delivery pipeline. The metadata may be embedded in the guard bits or least significant bits of chrominance channels of video data. Methods are provided for managing the encoding, delivery and decoding of the metadata to avoid unintentional communication of reserved words, minimize image artifacts which may result from overwriting least significant bits with metadata, prioritize delivery of metadata in the event of limited metadata bandwidth, and facilitate timely delivery of metadata to a downstream device.
