ST 2048-1:2011 - SMPTE Standard - 2048 × 1080 and 4096 × 2160 Digital Cinematography Production Image Formats FS/709

(1.1) This standard defines a family of progressive sample structures of 2048 × 1080 and 4096 × 2160 images for D-Cinema content creation as defined in Table 1 and Table 2 in Section 5. This standard specifies: — R′G′B′ color encoding and digital representation — Y′C′

color encoding and digital representation — This standard also defines tristimulus values and reference white of Free Scale-Gamut (FS-Gamut), Free Scale-Log (FS-Log) curve and a Color VANC packet. The FS-Log curve has an affinity with the sensitivity of human eye and can specify a much wider dynamic range than the nonlinear curve defined in Recommendation ITU-R BT.709. The Color VANC carries tristimulus values, reference white and parameter values of the FS-Log curve. — An auxiliary component A may optionally accompany R′G′B′, Y′C′
