I am going to use ADV7604 in my system. I want to use ADV7604 to change the contrast and brightness of my incoming DVI/HDMI signal, then transmit the digital 30bit RGB signal to the next stage. There is one thing on CSC (color space convertor) that is not clear. From the hardware manual "ADV7604 HW RvF Aug'10.pdf" on page 202, it looks the DPP CSC and CP CSC can not be enabled at the same time. But From the same document page 17, it looks the two csc can be cascaded and enabled independently. From my understanding, if I want to change the contrast and brightness of my incoming DVI signal (encoded in RGB not in YCbCr), it shoud be RGB to YCbCr first in one CSC, then change the contrast and brightness, then YCbCr to RGB again to output. Can someone help me to find out whether it works? Thank you all!
