ADV7403 to ADV212 Vdata interface

I am trying to interface the ADV7403 to ADV212 Vdata interface and have a problem avoiding glue logic between devices when using 10-bit 4:2:2 YCbCr interface.  There are several video standards that a single ADV212 can encode both Y and C data e.g. Component YPbPr 525i, 525p, 576i, 576p, RGB VGA.  For theese standards video format the ADV7403 recommends using the component processor but component processor can only output DDR on pixel interface, except for  one mention that it can do 525i and 576i in SDR mode.  ADV212 only has SDR pixel interface on V-data bus.  Is there a way around this?


Thanks in advance for any help.
