_DXVADDI_FREQUENCY structure

Description

The DXVADDI_FREQUENCY structure describes the video frame rate in Hertz (Hz). For example, NTSC TV is 60000 over 1001.

Members

`Numerator` [in]

The numerator of the frequency fraction.

`Denominator` [in]

The denominator of the frequency fraction.

Remarks

The user-mode display driver must interpret the video frame rate for the following special cases as indicated:

Numerator/Denominator = 0/0 is interpreted as an unknown frequency.
Numerator/Denominator = n/0, where n is any number, is interpreted as invalid.
Numerator/Denominator = 0/n is interpreted as zero frequency.
