Contributor[HDMI IP] info_avi[112] control bit is assigned to Virtual Pin -> why?
Hi amildm,
Good day.
>Will the infoframe packet be sent out when info_avi[112]=1and blocked/filtered out when info_avi[112]=0?
I believe the above statement is incorrect.
Based on the Cyclone 10GX schematic file:
C10gx Schematic file
and the HDMI IP User Guide:
HDMI IP User Guide
when info_avi=1, it will not insert the Infoframe.
With that, the Infoframe packet will be sent out when info_avi[112]=0 (user_pb_2=1, released) and blocked/filtered out when info_avi[112]=1 (user_pb_2=0, pressed) .
Hope this answer your question.
Thank you.

Good day.
It is best to use latest version of Quartus.
>Why this signal is assigned to the external pin? What purpose for?
Based on HDMI example design, this pin is connected to the user pushbutton to control a feature where you can see or unsee the infoframes in the transmitted signal.
This example design uses this input to control this feature.
