VIP Framebuffer locked rate support: Howto setup?

If locked framerate is enabled in the framebuffer IP core, locked framerate may be controlled through registers Input Frame Rate and Output Frame Rate. These registers have an impact on frame dropping and frame repeating which lastly controls the resulting framerate.

But nowhere I can find information of how to to it exactly. Assuming that the value Input Frame Rate is N I can imagine that maybe every Nth frame is dropped. And Output Frame Rate may work accordingly with frame repetition.

Can someone give me a hint on that?

    Hi dlim,

    thanks for your quick response! I am working with Quartus version 16.1 - so I stick mainly to its documentation and this application example does not exist in this version.

    I took a short look in 18.1 documentaion but did not look carefully enough.

    Regards,
