Write portion of frame buffer

Hi i would like, when i receive a new frame, to select the central part of it (clip) and store it in memory. The position where i save this piece of frame should depend on the frame number like this...

What kind of frames? Ehternet or whatever?

DVI Video Frames

Where do frames come from?

From a Camera

What IP or module are you using?

Altera VIP , DDR2 Memory Controller

How are you supposed to write into memory?

Now i write all the frames into a frame buffer

i would in future:

Get Video Frame 1 --> Take a small portion of it--> write in position 1

Get Video Frame 2 --> Take a small portion of it --> write in position 2

and so on...

Then i would read a video frame composed of those pieces:

| 1 | 2 | 3 | 4 |

Every time i get for example frame 1, i refresh the portion of video in position 1
