History

Early history

In the CIE 1931 xy chromaticity diagram the DCI-P3 color space covers 45.5% of all chromaticities and 86.9% of Pointer’s gamut. In the CIE 1976 u’v’ chromaticity diagram the coverage is 41.7% and 85.5% respectively.[2] The blue primary color is the same as sRGB and Adobe RGB;[1] the red primary color is a monochromatic light source and has a wavelength of 615 nm. DCI-P3 was defined by the Digital Cinema Initiatives (DCI) organization and published by the Society of Motion Picture and Television Engineers (SMPTE) in SMPTE EG 432-1 and SMPTE RP 431-2.[3] As a step towards the implementation of the significantly wider Rec. 2020 it is expected to see adoption in television systems and in the home cinema domain.[4]

On November 10, 2010, SMPTE published SMPTE EG 432-1:2010.[5]

On April 6, 2011, SMPTE published SMPTE RP 431-2:2011.[6]
