about Chroma Resampler IP

hello

I use the Video and Image Processing IP core like this CVI(4:4:4)-> Chroma Resampler IP(4:4:4-4:2:2) -> CVO .When I use the Embedded Sync signals with CVI IP ,all work well.But when I use the separate wires Sync signals with CVI IP, the underflow of the CVO IP is high .

what's the problem ? Can anyone help me?

    maybe you get also an overflow at the cvi?

    Try to use a Framebuffer-IP. It seems that the output needs data, while the cvi is not sending data...
