I am currently looking to build a circuit that converts vga signals to composite video; however, I would also like it to crop. All video would be cropped down to 320x234. If possible I would also like buttons to move the cropped area. Where would I start if I wanted to make something like this?
Here is a sample of what I would like it to do:

As you can see, it will be used to display the screen of a gps.
Thanks for any help!
