Reported Speech (or Indirect Speech) is when you talk about what other people said. On this video the teacher tells you to visit his website to finish the lesson, but his site is not free, so I'll tell you the end. He says that when the introductory verb is in the present we don't change the tenses. He gives the example "I come from Japan", the reported speech in the present is: "he says that he lives in Japan" (the conjunction THAT is optional).
