full hd video frame rate conversion by using cpld?

Hi all I'm wondering if a CPLD such as MAX V can convert 1920*1080 120P video to 1920*1080 60P. I've checked in MAX V handbook p3-26 (http://www.altera.com/literature/hb/max-v/max5_handboo...

I would consider the following things:

1) speed of internal logic (no only IO): is this frame rate conversion supposed to work just dropping the frames? Or do you want to do some elaboration? If you need elaboration, consider how fast you can make it elaborate.

2) compatibility of the external frame memory interface with the selected device. In a frame rate conversion application you may need the external memory.

3) I can confirm that you need to count also the blanking period (if this was the original question)
