1.2.2.2.2 SDTV Application
1.2.2.2.2.1 SDTV Application with Video Data Range
The two equations presented in this section are for the SDTV application. The chromaticity parameters are
defined by ITU-R601 standard.
The input video data for these equations should be within the range that is defined for video application.
In an 8-bit system:
•
Rd, Gd, Bd, and Yd will be in the range [16-235]
•
Cb and Cr will be the range [16-240]
•
D = 1
In a 10-bit system:
•
Rd, Gd, Bd, and Yd will be in the range [64-940]
•
Cb and Cr will be in the range [64-960]
•
D = 4
