Re: color format of HDMI Rx IP

Hi @daram123

 

Would you use InfoFrames which is called "AVI (Auxiliary Video Information)" ?

It depends on the HDMI Source that drives to HDMI RX IP, as long as EDID in HDMI Rx supports it, the color format can be detected.  If you follow chapter 5 of PG236, run example design, type "i"menu, it tells you the color format and all other color information for the incoming stream.
