Utility Functions
This section describes a number of utility functions that may be supported by some video digitizer components.The
VDSetPLLFilterTypeandVDGetPLLFilterTypefunctions allow applications to control which phase-locked loop (PLL) is used by a video digitizer component that supports multiple PLLs.The
VDSetFieldPreferenceandVDGetFieldPreferencefunctions allow applications to control which field is used for some vertical scaling operations.The
VDSetDigitizerUserInterruptfunction allows applications to install custom interrupt functions that are called by the video digitizer component.The
VDGetSoundInputDriverfunction allows an application to retrieve information about a digitizer's sound input driver.The
VDGetPreferredTimeScalefunction allows an application to determine a digitizer's preferred time scale.
