	~~One paragraph overview~~ of the ~~lecture~~		In this lecture, we look at one of the reasons why networked control systems problems are difficult. Due to the distributed nature of the problem, different controllers may have access to different information sets at every time. We introduce the concept of information patterns, and identify some patterns that permit simple solutions to the optimal control problem.
