    We are working on a product that is a multi video protocol to HDMI converter with OSD/overlay generated by R-Pi and have shortlisted ADV7850 as a potential IC. We have queries regarding its functions & capabilities and did not find enough details in the data-sheet. We are hoping that this is the right forum for it.
