Dear All

Could someone explain me how to make rectangle or/and text on video coming from camera. OSD for video

I use Hamsterworks's and Anton's projects and they works separately, but how to add them together ?

ref. links:

I use VHDL code and ML402, It highly appreciate your efforts for helping me , to get some link and explanation..

I cannot understand how is it works, and whether someone implemented this, i thought just to use rgb outpot 8 bit devided to 4 bits video and 4 bits for rectangle or text))):

You can try playing with "vga.vhd" from the URL you posted.

This site could help you learn something related that you could then adapt to VHDL and your situation.

I'm just guessing that your question was very broad and that's why nobody answered. Perhaps it was not clear whether you wanted to hire someone to do this or get some learning resources so you can do it yourself.

If you would like to understand how it works refer to this book:
