Coding-independent code points (CICP) is a way to signal the properties of a video or audio stream.^[1]^[2] It can describe the color profile of videos (and still images) in a simpler way than the use of ICC profiles.^[3] It is defined in both ITU-T H.273 and ISO/IEC 23091-2.^[1] It is used by multiple codecs including AVC^{[citation needed]}, HEVC^{[citation needed]} and AVIF.^[3]

Standardization

ITU-T H.273, for video.

ISO/IEC 23001-8:2016, part of MPEG-B (system technologies). Later split into three parts:
- ISO/IEC 23091-1:2018, for systems.
- ISO/IEC 23091-2:2019, for video. (Revised by ISO/IEC 23091-2:2021).
- ISO/IEC 23091-3:2018, for audio.

Common CICP values

Common combinations of H.273 parameters are summarized in ITU-T Series H Supplement 19.^[4]
