ContributorHDMI IP -> DRMI (Dynamic Range Mastering InfoFrame) -> how to derive?
You are referring to the Design Example for Arria 10, but I'm working with the Cyclone-10.
Instructions for Cyclone 10 DRMI Filtering are different:
but they are not compatible with the generated code...
The User Guide for Arria 10, which you are referring to, is compatible to the generated code, which I have in my project...
Anyway, I'll set the multiplexer_in0_valid signal to '0' according to your recommendation and let you know whether it works.
Frequent ContributorHi amildm,
Good day.
After further discussion with internal team, to passthrough HDR infoframe, you need to change below bit to 0 in the rxtx_link.v file located in the rtl folder.
rxtx_link.v file
Thank you.

amildmHi ZulsyafiqH_Intel,
Thanks a lot to your response.
I'll do the mentioned by you change and test the design on the board.
I'll return to the office next week, so please be patient until my response.
Thank you again,

I've changed the mentioned block_ext_hdr_infoframe signal to drive '0', but still what's going out is the internally generated HDR metadata, not one which the video source sends.
Here is the HDR, which was received (captured by Quantum Data):
Should anything else be changed in the RTL in order to pass through the original DRMI frames with the original HDR metadata?
