TMDS1204: Regarding the use of AC coupling and DC coupling for HDMI signal transmission

Part Number: TMDS1204

Hello!

When I used TMDS1204 this chip, I had such a question, I want to know what is the difference, advantages and disadvantages of using AC coupling mode and DC coupling mode for HDMI signals? What is the principle of signal transmission and impedance matching of each of them? Please answer the question.

Thank you so much!
