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
Thiago

Hi Thiago,
what output format are driving with the CVO? DVI, VGA?
Could you post the settings you are using or a screenshot of the settings you are using?
Also what are you driving the CVO with? It needs to be fed with interlaced video for NTSC output to work. It can't create interlaced video from a progressive input.
Regards,
Gareth.
