ADV7611, ColorSpace Detection problem,

Hi,

    I have problem with color space detection by ADV7611 and ADV7842.

If i connect HDMI source (which probably doesn't respect EDID) directly to ADV, ADV recieves AVI infoframe and correctly detects colorspace. But if i add CLUX-14E (1x4 HDMI v1.3 Distribution Amp) between them, adv doesn't receive AVI infoframe. ADV thinks that the video probably is in recommended RGB color space. So if video's colorspace is YCbCr, colors are converted.

       I checked video from CLUX-14E by Tektronix WVR 5250, and analyser recieve AVI infoframe.

 

Where i should look for problems?

 

Thanks and regards,

Grzegorz
