How to add HDMI support in video miniport driver?

I have some experience on VGA compatible video miniport driver development. Now the interface between the display card and monitor changes to HDMI from VGA interface. I don't know how to modify the video miniport driver to support HDMI interface. As I know in the VGA compatible video miniport driver, I need to implement SVGA functions. Now for HDMI, what should I do?
