Video Overlay and Video basics

Hi together,

i'm planning to buy the DE2-70 board for some video application due to its two video-inputs. I've got to applications:

- Reading two videosignals and put them on a single videosignal, divided in to vertical parts. At the left half of the output video is the first videosignal, the right half is of the second videosignal. Both videosignals have to be stretched at the half size. That's for generating a 3D-Videosignal for usual videoglasses.

- Reading two videosignals. The first is a normal videosignal, the second is a b/w-videosignal. Where on the second videosignal are bright parts, these areas have to be marked in red on the first videosignal.

Can you tell me if that all is possible? Can the board do it all in real-time? How huge would you suggest the delay to be?

Thank you very much,

propwell

    both can be done. The first should be quite possible but you'll probably need a frame store to align the videos, meaning you'll get a 1 frame latency. If they are synced you could do it with a couple of line delays The second is a bit more complicated, and may require some processing power of a CPU. Inserting colour over the top is also pretty hard in a YCbCr stream. Good luck.
