How Does HAVi Display devices intersct with hardware

Hi,

I am working on HAVi ui implementation.

i had gone through the HAVi ui spec(chapter 8 of HAVi spec) and portions of

Steven Morris's book that discusses about HAVi display devices and their configuration.

What i don't understand is the flow of data from HAVi app to the hardware.

After referring some code i understood its some hardware specific calls that sets the hardware according to the device configuration set in the HAVi display device.

The working mode is set like that but..

How does HAVi make hardware to display the video, widgets and background.

Please help me on this..
