A little background info, almost 30 years ago (Damn am I getting that old) I worked for IBM as a technician working on Mainframe computers. 8b/10b was very new back then and used to connect drives to the mainframe computers. For perspective these drives were the size of washing machines.
Back in those days we would change out a board that needed to be replaced and then go back to the shop diagnose the problem and repair the board to be used in another repair if needed. Today boards are disposable.
A good technician not only knew his job but also knew when the problem needed expertise above his level. Back then we would call the chip and board designers. Today they also have a sub-specialty called integrity engineers.
How does this relate? First 8b/10b is the predecessor to DVI/HDMI. They just have more capabilities, faster speeds and HDCP but the basics are very similar. Second, I am NOT an expert but have a good understanding of the basics. Just wanted to make that clear.
