I need to convert RGB component with sync on green to parrallel pixel bus. I see that the Decoder ADV7182 is able to convert from YPrPb to parrallel bus, but before I need to convert from RGB to YPrPb. The problem is that I have the sync only on green not in all the component, this could be a problem?

I see also the ADV 7403 decoder that, from data sheet, seems be able to convert both component RGB and YPrPb, but from user manual seems that is able to convert only YPrPb for component and RGB only for GR. can you say to me if the RGB component conversion is possible or not?
