General information about color space

Following is some general information about color space.

Color space standards

Each color space has different standards for the three sets of color data.

To read this table, find a color space in the first column, then read across to identify the three sets of color data for that color space.

MediaLive term for the color space

Complies with this color space standard

Complies with this brightness function standard

Complies with this standard for display metadata

601 or rec601

SDR rec. 601

BT.1886

Not applicable. This color space doesn't include display metadata.

709 or rec709

SDR rec. 709

BT.1886

Not applicable. This color space doesn't include display metadata.

HDR10

rec.2020

SMPTE ST 2084 (PQ)

SMPTE ST 2086

HLG or HLG 2020

rec.2020

HLG rec. 2020

Not applicable. This color space doesn't include display metadata.

Note that HDR10 and HLG use the same color space. They use different brightness functions and display metadata standards.

How MediaLive supports the color space standards

On the input side, MediaLive can read the metadata for all four color space standards. On the output side, MediaLive can produce the color space (including the metadata) for three of the color space standards.

Color space versus video resolution

Color space refers to the range of color. MediaLive supports the following color spaces:

  • SDR (standard dynamic range)

  • HDR (high dynamic range) color spaces

Resolution refers to the video pixel count. MediaLive supports the following resolutions:

  • SD (standard definition).

  • HD (high definition).

  • UHD (ultra-high definition). For UHD, MediaLive resolutions up to 4K.

The following combinations of color space and resolution are typically used:

  • SDR color space can be associated with SD, HD, and UHD video.

  • HDR color space can be associated with HD or UHD video.

HDR isn't typically associated with SD content, but MediaLive does support this combination.
