Why does the Arria V and Stratix V HDMI design example cause no display or image distortion on HDMI sink ?

When using Arria^®V and Stratix^®V HDMI IP core design example, switching between different color space using certain HDMI source might cause no display or image distortion on the HDMI sink.

The root cause is that there is a problem in the read request from the auxiliary bypass FIFO. This caused missing end-of-packet in the last auxiliary packet.

The problem occurs when the last auxiliary packet which missing end-of-packet involves auxiliary video information (AVI) infoFrame, which contains the color space information required by the HDMI sink.

This problem has been fixed in Quartus® Prime Standard Edition version 17.0 Update 1.
