Copy Video Stream Several Times

Hello, I try to copy my incoming video stream several times. My first ideas were to split the signal before using the SOPC and use multiple clocked video inputs. This works fine with 2 inputs, not...

Is there a better approach to cloning video output than using multiple CVIs at the video source? I have a system where a video input is processed (clip/scale, deinterlace, frame buffer) and then mixed with OSD and test pattern generator. I want to show the same mixed output video on two different interfaces VGA and SDI. I am thinking of these two approaches:

1. Use Color Plane Seq to split the AV-Stream and use frame buffer on each path; OR

2. Take the output from the VGA CVO block and feed it back into a CVI block to regenerate AV-Stream then send it to another CVO block connected to the SDI core. Not sure if I need a Frame Buffer though.

Any suggestions? Note, both VGA and SDI will have same resolution and frame rate to keep things simple.
