At 2:40, when the 4 modes are explained a very important piece of info is left out: they are talking about an INPUT pin of the IC ! Of course, it is trivial - but only once you understand it.

Very nice introductory video. Thanks for posting. It gave me a good and clear rudimentary understanding of boundary scan and JATG. Best explanation ever.
