Hello,
I need help on how to successfully transport the Vertical Ancillary (VANC) packet from with the configuration below.
----(embedded video sync)---> CVI ---> Frame Buffer ---> CVO ----(embedded video sync)---->
The input video format is 1080i60, Vertical ancillary packet at lines 19 and 20 for Field 0 and lines 582 and 583 for Field 1.
CVI setting : Extract ancillary packet (checked)
Frame Buffer setting: Set the value of non-video packet handling setting to maximum.
CVO setting : set the appropriate ancillary insertion lines
The problem is that all the vertical ancillary packet has been concatenated in line 19 of Field 0 as seen on the output of CVO.
When I tried to simulate using a smaller video size (i.e. 128x128) and set the ancillary line for Field 1 to the appropriate line number for 128x128 video size, I have noticed that cause of the concatenation is from the Frame Buffer.
I am using Quartus 14.1.
Does anyone experienced this problem?
Thank you.
