For 8-bit/channel encoding:

Transformation from CIE 1931 XYZ values to sYCC values

For N-bit/channel encoding (N > 8) greater accuracy is required, i.e. for 16 bit/channel:

In the sYCC encoding process, negative sRGB tristimulus values and sRGB values greater than 1.0 are retained.

For 8-bit/channel encoding (the resulting values shall be limited from 0 to 255):

For N-bit/channel encoding (the resulting values shall be limited from 0 to ):

Transformation from 8 bit sYCC values to 8 bit sRGB values

Note: Since the 8 bit sYCC values are not limited by the gamut of 8 bit sRGB values, some kind of mapping is needed for the colors that contain over-ranged nonlinear floating point values (under 0.0 or over 1.0) when converting 8 bit YCC to 8 bit sRGB

Transformation from 8 bit sRGB values to 8 bit sYCC values

Extended gamut encoding for sRGB: bg-sRGB and its YCC transformation: bg-sYCC

Transformation from bg-sRGB values to CIE 1931 XYZ values

For 10 bit/channel encoding (WDC = 894, KDC = 384):

For N-bit/channel encoding (N > 10):

If then

For 8 bit/channel encoding:

Transformation from CIE 1931 XYZ values to bg-sRGB+ values

For N bit/channel encoding (N > 10) greater accuracy is required, i.e. for 16 bit/channel encoding:

In the bg-sRGB encoding process, negative sRGB tristimulus values and sRGB, tristimulus values greater than 1.0 are retained.

For N bit/channel encoding:

For 10 bit/channel encoding (WDC = 894 and KDC = 384):

For 10 bit/channel encoding the resulting bg-sRGB values shall be limited to a range from 0 to 1023.

For other N bit/channel encoding (N > 10):

For N bit/channel encoding (N > 10) the resulting bg-sRGB(N) values shall be limited to range from 0 to .

10 bit/channel encoding shall be the default bg-sRGB encoding bit depth. Other bit depths may be unsupported for general use.
