The main problem is probably my unterstanding of how the Clocked Video Output IP core exactly works. How do I change the output-input timing relation? Since the input timing is fixed, I can only change the output timing. And since I do not have a framebuffer, the output framerate must match the input framerate exactly. My unterstanding from the VIP Suite User Guide is the following: As soon as a new input frame starts, the scaler starts upscaling the video data delivered by the CVI core. When the fifo at the CVO core has reached the set threshold, output of the active image data starts. This provides some synchronization to lock both framerates, but it violates the set timing values for the output if the framerates do not match otherwise. Is this correct or did I miss an important point?
