@xudyes it is the case right now.  So just the UART interface addresses could tell the color format. counting the frame size using tuser is done.

Thank you.

Hi @daram123

 

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

@daram123

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.

@daram123

For Video resolution, you can figure out the active frame size by counting tuser(start of frame) and tlast(end of the line). For the color format, I don't think you can use PL to detect all the video source. Unless your source sends the pure color, and then you can judge it based on the tdata values
