Abstract
The present disclosure relates to a terminal device, a communication method, a program, and a communication system, which can enable one-on-many wireless communication among terminal devices with less trouble for the user.
A communication system according to the present disclosure is a communication system in which one parent device and a plurality of child devices perform one-on-many wireless communication. The parent device includes a management unit which manages group information representing a group made up of two or more child devices to which a child device belongs, and a child device connecting unit which establishes wireless connection with the child device which performs notification of the group information that matches the managed group information, and consecutively establishes wireless connections with a plurality of child devices. On the other hand, the child device includes a notifying unit which notifies the parent device of group information representing a group made up of two or more child devices, to which it itself belongs, and a parent device connecting unit which establishes wireless connection with the parent device in response to a predetermined trigger. The present disclosure can be applied to a system which distributes data by one-on-many wireless communication.
