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 

Thiago

As far as your luma chroma swap. As you are doing it serially I can think of two ways to handle the problem. 

 

1 - I would just write a small HDL block after the clocked video output that would resequence the data. 

 

2 - You could try the Altera Color Plane Sequencer just before the Clocked Output block.
