Components of color space

There are four components to color space:

  • The specific color space that applies to the video content. The color space specifies a range of pixel colors that can apply to the content.

  • The color space metadata, which identifies the color space being used. If this metadata is present, the content is said to be marked for a color space.

  • The brightness function that applies to the color space. The brightness function controls the brightness of each pixel. The brightness is also known as gamma tables, electro-optical transfer function (EOTF), and transfer function.

  • The brightness metadata, which identifies the brightness function being used.

  • The display metadata that applies to the color space. Not all standards have this metadata.

The video might use a specific color space and a specific brightness function. The video might also carry color space metadata that describes aspects of the color.
