DE2 Video Examples- Interlaced video handling?

Honored Contributor II



I just started working on the examples in the University Program. When I take a look at "Example_4_Video_In", I can see the incoming images (720*244 or 720*243) being clipped at 640*240, before being scaled down to 320*240.  


Can someone explain how the interlaced video stream is being handled? Are the even or the odd frames just dropped? Or are both field handled as normal "progressive" images? 


Because I can`t see any deinterlacing taking place...
