Using the ADV8003 TX, how do I transmit  extended colorimetry video such as sYCC601, xvYCC709, xvYCC601, AdobeYCC601 and AdobeRGB

To send the extended colorimetry formats the correct fields need to be set in the AVI info-frame from the TX.

0xEC56 [7:6] = 11B

0xEC57 [6:4] = 010b ->sYCC601; 011B ->ADOBE YCC601; 100B ADOBE RGB
