SMPTE ST 2094文档套件定义了用于内容色卷转换的元数据。元数据取决于内容，可以随场景或图像的不同而变化。元数据旨在转换高动态范围和宽色域（HDR/WCG）图像本质，以便在比用于掌握图像本质的主控显示器的颜色体积更小的显示器上呈现。多个应用程序提供特定的颜色体积变换。该标准是2094套件的一部分，指定了通用定义，包括转换元数据集和元数据参数，供2094套件的其他部分使用。 2094套件的其他部分为颜色体积变换提供了载体表示和其他特定于应用程序的元数据参数。

The SMPTE ST 2094 suite of documents define metadata for use in color volume transforms of content. The metadata are content-dependent and can vary scene-by-scene or image-by-image. The metadata are intended to transform High Dynamic Range and Wide Color Gamut (HDR/WCG) image essence for presentation on a display having a smaller color volume than that of the mastering display used for mastering the image essence. Multiple applications provide particular color volume transforms.This standard, a part of the 2094 suite, specifies common definitions, including a transform metadata set, and metadata parameters, for use by other parts of the 2094 suite.Other parts of the 2094 suite provide representation for carriage and additional application-specific metadata parameters for color volume transforms.
