SGGetVideoDigitizerComponent
The SGGetVideoDigitizerComponent function allows the sequence grabber component to determine the video digitizer component that is providing source video to your video channel component. For example, the sequence grabber component can use this function to obtain access to the video digitizer component so that the
grabber component can set the digitizer's parameters. See the chapter "Video Digitizer Components" in this book for information about video digitizer components.

Identifies the channel connection for this operation.

DESCRIPTION
The SGGetVideoDigitizerComponent function returns a component instance that identifies the connection between your video channel component and its video digitizer component. If your video channel component does not use a video digitizer component, set this returned value to nil.

SEE ALSO
If the sequence grabber component changes any video digitizer component parameters, it notifies your sequence grabber channel component by calling your SGVideoDigitizerChanged function, which is described in the next section.
