Hello,

 

I have a question about how we should set the "cp_vid_std" register of ADV7480.

As the H/W manual mentions on page 166 and 167, when "cp_vid_std" is set to 0x53(720p), 0x54(1080i) or 0x5E(1080p), I think we should set "de_h_start[9:0]" and "de_h_end[9:0]" to center the picture correctly.

 

The HDMI input resolution which the customer wants to handle on their project is 1080p, 1080i, 720p and 480p.
Any resolution is good when free-run.
In this case, how should we set the "cp_vid_std"?
(Is "cp_vid_std" = 0x4A(480p) good?)
When we set cp_vid_std = 0x4A(480p), don't we have to set "de_h_start[9:0]" and "de_h_end[9:0]" to center the picture correctly?

 

Thank you!
Best regards.
