Abstract

[Object] To perform appropriate transmission band control.

[Solving Means] An information processing apparatus includes an acquisition section and a controller. Here, the acquisition section acquires user information generated by a user operation when information based on a stream communicated between another information processing apparatus via wireless communication is output from an output section. The controller performs band control of the stream communicated between another information processing apparatus via wireless communication based on the user information acquired by the acquisition section.
