--- Quote Start --- Can you explain exactly what it is that you are trying to achieve? --- Quote End --- Hi gwall, I try to explain: The signal comes from my notebook. I have a picture in which are 9 other pictures, like the picture I have uploaded. (I think I never wrote about four streams, they are 9 ;) ) It comes in over the Bitec HSMC Digital Audio/Video Adapter via DVI. In Quartus II, I have the SOPC system with 9 clocked video inputs, every input becomes the picture as his input. The clippers, which comes next the CVIs, clipps each one part of the input picture, so that I have the 9 different pictures (yes, they are all different, just a little bit). Then I scale them up and out of the SOPC system, I mix them together to achieve a 3D picture. If all Clippers clipp just the picture at the left top, they are delayed just a few pixel. But if I clipp different parts of the picture, the output streams are delayed vertical. What I mean with "delayed vertical" is, that I can see the vertical blankings (after the mixer) of 8 of the pictures, just the first is not delayed (because I use his h_sync and v_sync to mix all together). Because of the mixing procedure, I need all nine h_syncs and v_syncs to be exactly the same. Thank you!
