Hi Tricky!

thanks for your guideline.

I have made the following design flow:

deinterlacer >> 1to2 demux(y=0,Cb and Cr = real video values) >>chroma resampler >> color space converter >> scaler megacore functions.

So it means I have made Y=0, and play the video with just Cb and Cr values. After that I have used color space converter to make it RGB(that is connected to vga).

I think it is fine because I set Y=0 (it means brightness=0) so output must be dark(as I brief in last post).
