Clocked video output

Hello

I'm trying to use the Clocked Video Output IP with the SOPC builder

I need to output a NTSC (4:3 525 lines) video with separate sync signals. To create the separate sync signals the wizard needs the following parameters:

Field 1

Horizontal sync (pixels)

Horizontal front porch (pixels)

Horizontal back porch (pixels)

Vertical sync (lines)

Vertical front porch (lines)

Vertical back porch (lines)

Field 0

F rising edge line

F falling edge line

Vertical blanking rising edge line

Vertical sync (lines)

Vertical front porch

Vertical back porch

I've tried different combinations (which I thought were OK) but couldn't get the video correctly sync'd. Anyone knows the correct values?

Thank you
