[HDMI IP] AVI InfoFrame

[amildm]

Hi All,

The question is related to the Intel HDMI IP.

According to the Table 23 in the UG-HDMI 2021.06.25, the AVI InfoFrame port has 113 bits width (bit 112 is a control bit).

But, in the generated HDMI IP, the port has only 112 bits width. Why? What's missing?

Thanks!

Hi Dmitry,

Thank you for you patience.

>But, in the generated HDMI IP, the port has only 112 bits width. Why?

Yes, you are correct, HDMI only have 112 bits width and bit 112 is a control bit.

Sometime it could be a documentation typo/update delay and it will require some time to be revised as it require approvals from the internal team before it can be released to the public. For this case, it is caused by documentation update delay.

Based on the latest HDMI User Guide, I believe you are talking is table 24, the AVI InfoFrame for Support FRL = 0,

The correct bit width is as you mention which is 112 bits.

You may refer to below link for the latest HDMI IP User Guide:
