HDMI IP -> DRMI (Dynamic Range Mastering InfoFrame) -> how to derive?
Hi,
In the HDMI Sink, the DRMI packets are mapped to the Address 0x88 of the Auxiliary Packet Memory Map:
But, how can I send the DRMI packets through the HDMI source? What's port should be used?
Thank you!
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.

Hi amildm,
Thank you for the update.

I have check with our internal team on this.
You may need to set multiplexer_in0_valid of the avalon_st_multiplexer instance in the altera_hdmi_aux_hdr.v file to 1'b0 to prevent the Auxiliary Packet Generator from forming and inserting additional HDR InfoFrame into the TX Auxiliary stream.

Hi amildm,
Thank you for the update.
Yes, you are correct, we have already issue a fix to update the design example user guide.
The update is scheduled to be fixed in the next release of the HDMI Intel® Cyclone 10 GX FGPA IP Design Example User Guide.
I’m glad that your question has been addressed, I now transition this thread to community support. If you have a new question, feel free to open a new thread to get the support from Intel experts. Otherwise, the community users will continue to help you on this thread.
Thank you.
