The Picture-In-Picture or PIP feature allows you to watch another channel in a small picture that fits on part of the main screen. There is no sound available from the program being viewed in a PIP picture for obvious reasons. I mostly use PIP to avoid commercials when I am watching live TV, so I can switch to another channel to watch while watching the original program in the PIP picture so I will know when the commercials are over. The video shows that the PIP pictures are available in different sizes and can be moved to various locations inside the main screen.
