Hi All,
I have a question that I have been battling for a couple of days. I am trying to use Altera's CVO IP to output NTSC video. I have tried to use the NTSC setting on the CVO but it automatically selects the Embedded sync options, but I need the sync signals on separate wires because my Video DAC requires the sync signals. This is the setup that I have: TPG -> CVO. I am using Quartus 13.0. Here are the settings that I am using for the TPG and the CVO. The pixel clock frequency I am using is 27Mhz.
TPG settings:
image width: 720
image height: 488
Bits per pixel per color plane: 8
Color space: RGB
Output format: 4:4:4
Color plane configuration: Parallel
interlacing: interlace output (F0 first)
pattern: Color bars
CVO settings:
image width: 720
image height: 487
Bits per pixel per color plane: 8
Number of color planes: 3
Color plane format: parallel
Interlaced video: checked
Syncs signals: On separate wires
Active picture line: 20
Field 1
Horizontal sync: 138
hfp: 0
hbp: 0
Vertical sync: 19
vfp: 0
vbp: 0
Field 0
F rising edge line: 266
F falling edge line: 4
Vertical blanking rising edge line: 264
Vertical sync: 19
vfp: 0
vbp: 0
pixel fifo size: 720
Fifo level : 719
I am not getting anything out on the screen with this setup. Can you guys shed some light on what I am doing wrong. Thank you for your help.
