Is there any one can help to check color value from ADV7619?
I posted the question in another discussion , Could you help to check it?
We designed two video capture card by ADV7619 and ADV7441A.
But we would like to convert color domain by ADV7619 or ADV7441A , As we tested , we got some different between ADV7441A.
The test result is ADV7619 provided poor peformance than ADV7441A.
(1) Pattern Generator (set RED Pattern) -> ADV7619 -> FPGA ->PCI-E -> PC
>> We got the RGB value from our system, the R = 251,G=0, B=0.
(2) Pattern Generator (set RED Pattern) -> ADV441A -> FPGA ->PCI-E -> PC
>> We got the RGB value from our system, the R = 254 ,G=0, B=0.
Pattern gen output is 1080p/YUV709.
We check CSC table from ADV7619 and ADV7441A H/W user guide. It shall be same. But the result might some different. Is there any reason for this result?
