We noticed that when YCbCr video is sent to ADV7511, the output is clipped to 1~254. But we want 0~255 full range. We tried to program 0x59 YQ[1:0] but doesn't seem to do anything. What else should we do?
Do you see the same problem on our evaluation board?
Have you tried RGB input.
How do you know your YCbCr source really goes to 255?
YCbCr normally does not go to absolute full range, only RGB normally goes to full range/
We don't have the eval board, however the ADV7511 is otherwise working fine on our board and sending video. We're sure our source (our own FPGA) is sending 0~255. What we're not sure about is whether ADV7511 is capable of sending 0~255 YCbCr as-is, or whether the receiving is doing the clipping.
I do not know if YCbCr gets clipped to 1-254. I have seen RGB go through full range. Let me ask someone else about this.
