My are you touchy. You could use a chill pill yourself.
Regarding component video, the convention today is to use that term for YPbPr video, although technically, as you say, the others you mentioned can also be called component video.
As far as being a teacher and finding someone that does not know, I though you fit into the latter category, which is why you asked your question.
When I attempt to answer questions, I try to ascertain the technical level of the person asking the question by noting any apparent technical inaccuracies or errors in the question. If I underestimated you technical knowledge, I apologize.
But I still don't know what it is. If you are capable of designing and laying out a high frequency analog circuit, then my reference to the Maxum product stands. But unless you really are intend on reinventing the wheel, it's much easier, faster, and probably not significantly different in cost to use an already built device such as the Gefen.
I have designed and built high frequency analog circuits, but I would never do my own component amplifier If I could buy one already built, because I know the large amount of time and effort it takes to get such an amplifier working properly. You would need a high frequency signal generator and oscilloscope at a minimum to properly test it after it was built. Oscillations and incorrect frequency response often appear even in well designed and laid out circuits. So you would need a very compelling reason to do your own design for this.
