I am making YCbCr encoder by ADV7393.

The ADV7393 make correct color for HD YCbCr output. Such as 1080i@60Hz, 720p@60Hz and 480p@60Hz.

But in the 480i@60Hz, the ADV7393 make wrong color. It looks green color very strong.

I set the register as Table 7.5 at page 94 on the datasheet exception 0x88.

I set the register 0x88 to 0x08 instead of 0x10.

How can I fix it?

Thank you.
