Video Digitizer Component Functions

Selecting an Input Source

This section discusses the video digitizer component functions that allow applications to select an input video source.

Some of these functions provide information about the available video inputs. Applications can use the VDGetNumberOfInputs function to determine the number of video inputs supported by the digitizer component. The VDGetInputFormat function allows applications to find out the video format (composite, s-video, or component) employed by a specified input.

You can use the VDSetInput function in your application to specify the input to be used by the digitizer component. The VDGetInput function returns the currently selected input.

The VDSetInputStandard function allows you to specify the video signaling standard to be used by the video digitizer component.
