ADV7604 configuration for 1080p (Autographics Mode)

Hi,

      I am using ADV7604 interfaced with FPGA to capture incoming video and store. I need to get lots of resolution support.

But main resolutions are 1920x1080 progressive @60Hz and 1920x1200 progressive @60Hz.

 

Video Input for ADV7604   : Analog RGB with discrete Sync (AIN 7,8,9 for RGB) and

Video Output by ADV7604 : 24 bit RGB with discrete Sync.

 

I had referred  the register setting script file ADV7604IO_ADV7604CP_ADV7604AFE_ADV7604HDMI_ADV7341B-VER.1.4c_RevA.txt. and i got 1920x1200 progressive @60Hz working with the settings mentioned at Graphics-9.1 section.

 

But from my understanding ADV7604 doesn't support 1920x1080 progressive @60Hz in PRIME MODE and  need to make register settings for Autographics mode. For this i had referred  ADV7604_Autographics_Pr0_230609.pdf  and i am trying to get the register settings for 1080p. Working example demonstrates 1080i formats. Bit confused on calculation of CP_START_SAV, CP_START_EAV, CP_START_VBI, CP_END_VBI, CP_START_VBI_EVEN, CP_END_VBI_EVEN for progressive video format.

 

So if some body could share the register settings for 1080p in GR mode it could be helpful.
