A digitizer reads analog data from a source, converts it to digital data, and writes the digital video data to another video component such as a graphic view:
TVideoDigitizer is a special type of video component that provides a common interface for all video digitizers.
To create an instance of the default video digitizer, you use the static function TVideoDigitizer::CreateDefaultVideoDigitizer. You can derive classes from TVideoDigitizer to support devices that provide specialized features, such as frame grabbing based on SMPTE time code, odd or even field capture, and programmable video signal characteristics.
NOTE
Digitizers
Classes derived from TVideoDigitizer must override the output port functions inherited from TMediaComponent.
