Abstract translation: 描述了使用可缩放视频编码（SVC）中的色域可扩缩性（CGS）参数和表格来识别和减少视频中的伪像的发生率的技术。 为颜色空间中的每个像素值分区执行CGS映射表的推导。 像素值域分为多个分区，每个分区独立优化。 当视频数据的较低层的色域不同于视频数据的较高层的色域时，视频编码器和/或视频解码器可使用CGS的色彩预测技术来产生层间参考图片。 当映射值被用作增强层块的层间预测参考时，伪像可能出现在序列的一些帧中。 视频编码器可识别潜在地包含这些伪像的块并且禁用这些识别的块中的层间预测。

Abstract translation: 通常，描述用于处理用于视频编码的高动态范围（HDR）和宽色域（WCG）视频数据的技术。 包括存储器和处理器的设备可以执行这些技术。 存储器可以存储压缩的分数色度坐标（FCC）格式的视频数据。 处理器可以使用一个或多个逆向自适应传递函数（TF）来对压缩的FCC格式的视频数据进行逆压缩以获得分解后的FCC格式的视频数据。 处理器可接着基于分解后的FCC格式的视频数据的对应亮度分量来反调整分解后的FCC格式的视频数据的色度分量以获得反向调整的FCC格式的视频数据。 处理器可将经逆调整的FCC格式的视频数据的色度分量从FCC格式转换为颜色表示格式以获得高Dyanmic范围（HDR）和宽色域（WCG）视频数据。

Abstract: In one example, a method includes determining, by a video decoding unit, a peak brightness value of a current display; obtaining, by the video decoding unit and for a picture of video data, one or more colour remapping messages that each correspond to a respective peak brightness value of a set of peak brightness values; selecting, by the video decoding unit and based on the peak brightness value of the current display, a colour remapping message of the one or more colour remapping messages; colour remapping, by the video decoding unit and based on the selected colour remapping message, samples of the picture of video data; and outputting, by the video decoding unit and for display at the current display, the colour remapped samples of the picture of video data.

Abstract: This disclosure relates to processing video data, including processing video data that is represented by an HDR/WCG color representation. In accordance with one or more aspects of the present disclosure, one or more Supplemental Enhancement Information (SEI) Messages may be used to signal syntax elements and or other information that allow a video decoder or video postprocessing device to reverse the dynamic range adjustment (DRA) techniques of this disclosure to reconstruct the original or native color representation of the video data. Dynamic range adjustment (DRA) parameters may be applied to video data in accordance with one or more aspects of this disclosure in order to make better use of an HDR/WCG color representation, and may include the use of global offset values, as well as local scale and offset values for partitions of color component values.

IPC: H04N19/70

Abstract: In an example, a method of processing video may include receiving a bitstream including encoded video data and a colour remapping information (CRI) supplemental enhancement information (SEI) message. The CRI SEI message may include information corresponding to one or more colour remapping processes. The method may include decoding the encoded video data to generate decoded video data. The method may include applying a process that does not correspond to the CRI SEI message to the decoded video data before applying at least one of the one or more colour remapping processes to the decoded video data to produce processed decoded video data.
