ITU YCrCb to RGB Standards

• Nested conversion formulas

  • R = Y + (2 - 2 Cred) Cr
  • B = Y + (2 - 2 Cblue) Cb
  • G = (Y - Cblue B - Cred R) / Cgreen

• 8-bit format
  • Y,R,G,B in [0,255]
  • Cr in [-128,127]
  • Cb in [-128,127]

• Range of G is [-134,390] for Rec 601-1

• RGB values are clipped to [0,255] and rounded
